As our loyal companions enter their golden years, their care needs become increasingly sophisticated. The aging process brings a dual challenge for many dogs: declining dental health that can lead to pain and systemic disease, and stiffening joints that reduce mobility and quality of life. Pet parents are no longer satisfied with single-purpose solutions, which explains the surge in demand for functional treats that tackle multiple age-related concerns simultaneously. The emergence of senior dental chews fortified with MSM (methylsulfonylmethane) represents a paradigm shift in preventative canine care—one that recognizes the interconnected nature of oral health and joint function.
Looking ahead to 2026, this category is poised for remarkable innovation. Manufacturers are moving beyond basic mechanical cleaning action, integrating therapeutic levels of joint-supporting compounds with advanced dental technology. These aren’t just treats with a sprinkle of supplements; they’re precision-formulated therapeutic tools designed to deliver measurable benefits. Understanding what separates truly effective products from marketing hype requires a deep dive into ingredient science, manufacturing standards, and the specific physiological needs of aging dogs.

The Growing Need for Dual-Purpose Senior Dog Care
The senior dog population is expanding rapidly as veterinary medicine advances and pet owners become more invested in longevity. Dogs over seven years old now represent nearly half of the canine population in many developed countries, creating unprecedented demand for age-specific wellness solutions. This demographic shift has revealed a critical gap in the market: products that address the concurrent decline of dental and musculoskeletal health.
Traditional approaches have treated these issues separately—dental chews for oral care, separate joint supplements for mobility. However, compliance becomes challenging when owners must administer multiple products daily. Missed doses and inconsistent routines diminish effectiveness. Dual-purpose chews solve this by integrating joint support into a daily dental routine that dogs already eagerly anticipate. The psychological benefit shouldn’t be underestimated; transforming a “medicine” into a reward increases adherence rates from below 60% to over 90% in most households.
Understanding MSM: The Joint-Support Powerhouse
MSM has evolved from a niche supplement to a cornerstone ingredient in veterinary orthopedics. This naturally occurring sulfur compound provides the building blocks for collagen, glucosamine, and chondroitin—essential components of healthy cartilage, tendons, and ligaments. Unlike some joint supplements that merely mask pain, MSM addresses the structural deterioration at the source.
For senior dogs, whose cartilage production has slowed dramatically, MSM’s role becomes critical. It reduces inflammatory markers while simultaneously supporting the synthesis of new connective tissue. The compound’s high bioavailability means it reaches therapeutic levels quickly, often showing noticeable improvement in mobility within 2-3 weeks of consistent supplementation. What makes MSM particularly valuable for dental chews is its stability during manufacturing; it withstands the heat and pressure of extrusion processes better than many other joint-supporting ingredients.
How MSM Works in Canine Joint Health
MSM’s primary mechanism involves donating sulfur groups for critical biochemical reactions. Sulfur is the third most abundant mineral in a dog’s body after calcium and phosphorus, yet it’s often overlooked in nutritional planning. In joint tissue, sulfur forms disulfide bonds that give cartilage its resilience and shock-absorbing properties. As dogs age, their ability to metabolize sulfur from food declines by up to 40%, creating a deficiency that accelerates joint degeneration.
The compound also exhibits powerful anti-inflammatory properties by downregulating NF-kB, a protein complex that drives inflammatory responses. This dual action—structural support plus inflammation reduction—makes MSM uniquely effective for osteoarthritis management. Recent 2025 studies have demonstrated that MSM combined with mechanical chewing activity creates a synergistic effect; the physical action of chewing increases blood flow to periodontal tissues, which may enhance systemic absorption of MSM through the highly vascular oral cavity.
MSM vs. Other Joint Supplements: What Makes It Unique
While glucosamine and chondroitin have dominated the joint supplement market for decades, MSM offers distinct advantages for delivery via dental chews. Glucosamine is notoriously unstable when exposed to moisture and heat, often degrading by 30-50% during the manufacturing process. Chondroitin molecules are large and difficult for senior dogs with compromised digestion to absorb effectively.
MSM remains stable at temperatures up to 240°C and has a small molecular weight, facilitating rapid absorption through both digestive and potentially oral mucosal routes. It also provides the sulfur necessary for the dog’s body to synthesize its own glucosamine and chondroitin, essentially teaching the body to help itself rather than simply providing external sources. This fundamental difference positions MSM as the superior choice for functional chews where manufacturing constraints are significant.
Why Dental Health Declines in Senior Dogs
By age seven, 80% of dogs show signs of periodontal disease, with prevalence reaching nearly 100% by age twelve. The aging process reduces saliva production, which normally contains antimicrobial compounds that keep oral bacteria in check. Concurrently, years of plaque accumulation have allowed biofilms to mineralize into calculus, creating a scaffold for pathogenic bacteria just below the gumline.
Immune function also diminishes with age, meaning the inflammatory response to oral bacteria becomes chronic rather than acute. This chronic inflammation damages not just periodontal ligaments but also contributes to systemic issues affecting the heart, kidneys, and liver. The pain associated with dental disease causes dogs to chew less vigorously, reducing the natural cleaning action that younger dogs achieve through enthusiastic chewing. This creates a vicious cycle where poor dental health leads to reduced chewing, which further worsens dental health.
The Connection Between Oral Health and Systemic Disease
The mouth serves as a gateway to the body, and in senior dogs, this connection becomes dangerously direct. Periodontal disease creates ulcerations in gum tissue, allowing bacteria direct access to the bloodstream. Studies have linked oral bacteria to endocarditis, kidney infections, and exacerbation of diabetes. For a senior dog with already declining organ function, this bacterial load can be catastrophic.
Inflammatory cytokines produced in response to oral bacteria circulate systemically, creating a state of chronic low-grade inflammation that accelerates joint degeneration. This is where the dual-action approach becomes scientifically elegant: by reducing oral inflammation through mechanical cleaning and antimicrobial ingredients, we simultaneously reduce systemic inflammatory load that worsens joint pain. The MSM then works systemically to further reduce inflammation while supporting tissue repair, creating a two-front attack on age-related decline.
The Synergistic Benefits of Combining Dental Care with Joint Support
The genius of integrating MSM into dental chews lies in the timing and delivery mechanism. The act of chewing stimulates blood flow throughout the head and neck region, potentially enhancing absorption of MSM through the highly vascular periodontal tissues. While most absorption still occurs in the digestive tract, this pre-absorption window represents an innovative delivery advantage unique to functional chews.
Moreover, the psychological benefit of pain-free chewing cannot be overstated. Dogs with joint pain often become sedentary, reducing their overall activity and even their enthusiasm for eating. A chew that simultaneously addresses dental discomfort and joint stiffness can reignite a senior dog’s zest for life. Owners report that within weeks of starting dual-purpose chews, their dogs show increased willingness to play, climb stairs, and engage with family members—benefits that extend far beyond the sum of the individual ingredients.
Key Features to Look for in 2026 Senior Dental Chews
The market evolution through 2025 has set new standards that discerning pet parents should expect in 2026 products. First-generation functional chews simply added MSM to existing formulations, but next-generation products are being designed from the ground up with both purposes in mind. Look for chews that mention “therapeutic level MSM” rather than just “contains MSM”—this indicates formulation around a specific dosage rather than token inclusion.
Texture engineering has become remarkably sophisticated. The ideal chew for 2026 should feature a dual-density structure: a firm outer layer that provides mechanical scrubbing action, and a slightly softer inner core that extends chewing time without requiring excessive force. This design acknowledges that senior dogs have more brittle teeth and reduced jaw strength. The chew should be firm enough to remove plaque but have enough “give” to prevent tooth fractures, a balance that requires advanced material science.
Advanced Texturing Technology for Superior Plaque Removal
2026 formulations are incorporating micro-ridges and cross-hatch patterns based on veterinary dental research showing these shapes disrupt biofilm more effectively than smooth surfaces. Some premium manufacturers are using 3D-printed molds to create textures that mimic the cleaning action of professional dental instruments. These patterns aren’t just marketing; they’re designed to reach the subgingival area—the critical zone where plaque causes the most damage.
The hardness should be measurable on the Shore hardness scale, with ideal senior dental chews falling between 70-80 Shore A. This provides enough resistance for effective cleaning while remaining safe for enamel that’s often worn thin after years of use. Reputable companies will publish these specifications, allowing you to make informed decisions based on your dog’s specific dental condition.
Optimal MSM Dosage Levels for Senior Dogs
Therapeutic dosing for MSM in dogs ranges from 50-100 mg per 10 pounds of body weight daily. For a 50-pound senior dog, this means 250-500 mg of MSM per day. Quality dental chews will deliver 25-50% of this dose per serving, with the understanding that dogs receive MSM from other dietary sources. Be wary of products that provide less than 10 mg per chew, as this represents sub-therapeutic levels unlikely to produce measurable joint benefits.
The 2026 trend is toward “stackable” dosing—chews formulated to complement rather than replace dedicated joint supplements. This allows veterinarians to adjust total MSM intake based on disease severity. Look for products that clearly state MSM content per chew and provide weight-based feeding guidelines that adjust the dose appropriately.
Natural, Limited-Ingredient Formulations
Senior dogs frequently develop food sensitivities and digestive issues. The 2026 standard favors single-protein sources, grain-free or ancient grain options, and absolutely no artificial preservatives, colors, or flavors. The base ingredient should be a high-quality protein like chicken, duck, or novel proteins such as insect meal for dogs with allergies.
Limited ingredient lists also reduce the risk of ingredient interactions that could degrade MSM potency. Vitamin C, for instance, can accelerate MSM degradation when present in high concentrations. Premium formulations separate these ingredients through micro-encapsulation or strategic layering within the chew structure, maintaining stability until ingestion.
Ingredient Quality: What Sets Premium Products Apart
The source of MSM matters enormously. While most MSM is synthetically produced, the starting material and purification process determine purity. Look for MSM produced through distillation rather than crystallization—the distillation process removes impurities more effectively, yielding 99.9% pure MSM without heavy metal contamination. Reputable manufacturers will provide certificates of analysis (COAs) showing purity levels and contaminant screening results.
The carrier ingredients should also meet human-grade standards. Many dental chews use meals and by-products that, while nutritionally adequate, may contain variable nutrient levels. Premium 2026 formulations are moving toward “named ingredient” sourcing—“chicken breast” rather than “poultry meal”—ensuring consistent nutrient profiles and digestibility. This is particularly important for senior dogs whose digestive efficiency has decreased.
Sourcing Transparency and Third-Party Testing
2026’s most trustworthy brands will offer blockchain-level ingredient traceability, allowing you to trace every component back to its source farm or facility. This isn’t just premium positioning; it’s essential for safety in an era of increasing supply chain complexity. Look for QR codes on packaging that link to batch-specific test results.
Third-party testing should include not just nutrient analysis but also microbial screening, heavy metal testing, and verification of active ingredient potency. The National Animal Supplement Council (NASC) seal indicates adherence to rigorous quality standards, but the gold standard is independent verification by organizations like ConsumerLab or specific veterinary university partnerships.
Avoiding Harmful Additives and Fillers
Senior dogs are particularly vulnerable to certain additives that younger dogs tolerate well. Glycerin, used to maintain chew moisture, can contribute to blood sugar spikes in dogs with metabolic issues. Artificial colors have been linked to behavioral changes and should be avoided entirely. Propylene glycol, still found in some mainstream chews, can cause Heinz body anemia and has no place in senior formulations.
The 2026 clean label movement extends to rejecting “natural flavors”—a vague term that can hide dozens of unspecified compounds. Instead, look for chews flavored with actual food ingredients like chicken liver powder or beef broth that provide both palatability and nutritional value.
Size, Texture, and Hardness: Matching Chews to Your Dog’s Needs
One size does not fit all in senior dental care. A chew that’s appropriate for a 60-pound Labrador with worn but intact teeth could fracture the jaw of a 10-pound Chihuahua with advanced dental disease. Premium manufacturers offer size-specific formulations that consider not just weight but also breed-specific jaw mechanics.
The chew’s dimensional design should prevent gulping—a common problem in eager eaters. Look for chews that are at least 1.5 times the length of your dog’s muzzle, forcing them to chew rather than swallow whole. For flat-faced breeds, specialized shapes accommodate their unique dental arcade and breathing challenges during chewing.
Breed-Specific Considerations
Brachycephalic breeds like Pugs and Bulldogs require softer, wider chews that distribute pressure across their crowded teeth. Their compromised respiratory systems also benefit from chews that can be consumed in under five minutes, reducing the risk of hypoxia during extended chewing sessions.
Large and giant breeds need extra-large chews with reinforced density to withstand their powerful jaws, but the hardness must be carefully calibrated to prevent slab fractures of their large premolars. German Shepherds and other breeds prone to dental issues benefit from chews with added enzymes like lysozyme and lactoferrin that boost the natural antimicrobial properties of saliva.
Adapting for Dogs with Missing Teeth or Dental Work
Dogs with significant tooth loss or those who have undergone dental extractions still need dental care for remaining teeth but can’t handle traditional hard chews. The 2026 solution is “adaptive texture technology”—chews that soften in the mouth after 30-60 seconds of saliva exposure, allowing dogs with compromised dentition to benefit from plaque removal without risking injury.
For dogs with crowns or bridges, look for chews specifically labeled as “restoration-safe.” These products use alternative cleaning mechanisms like enzymatic action and pH modulation rather than relying solely on mechanical abrasion. They clean through chemistry rather than physics, preserving expensive dental work while still delivering MSM benefits.
Safety Protocols and Quality Assurance in 2026
The regulatory landscape for functional pet products is tightening, with new FDA guidance expected to take full effect in 2026. This will require manufacturers to provide clinical evidence for health claims, particularly for products combining dental and joint benefits. Smart consumers should look for products that have already conducted peer-reviewed studies rather than waiting for regulatory mandates.
Manufacturing facilities should hold not just pet food certifications but human food-grade certifications like SQF (Safe Quality Food) or BRC (British Retail Consortium). These standards exceed traditional pet food requirements, implementing hazard analysis at every production stage. The facility should also practice segregated production runs for functional chews, preventing cross-contamination with non-functional treats.
Understanding VOHC Certification and Beyond
The Veterinary Oral Health Council (VOHC) seal remains the gold standard for dental efficacy, requiring clinical trials demonstrating at least a 20% reduction in plaque or calculus. However, for functional chews with MSM, this is just the starting point. The 2026 standard should include additional certifications specific to supplement delivery, such as NASC quality seals and potentially new certifications from the American College of Veterinary Nutrition.
Be cautious of products claiming “VOHC-accepted ingredients” rather than “VOHC-accepted product.” The distinction is crucial—the former means the ingredients have been used in accepted products but haven’t been tested in the current formulation. True VOHC acceptance requires testing of the final product, ensuring the manufacturing process hasn’t compromised efficacy.
Manufacturing Standards to Demand
Ask about the production method. Extrusion cooking, while efficient, can degrade MSM if temperatures exceed 150°C. Cold-press or low-temperature baking methods preserve ingredient integrity but require more sophisticated equipment. The best 2026 manufacturers are using hybrid methods—cold-pressing the MSM-enriched core while lightly baking the outer dental-cleaning layer.
Moisture content is another critical factor. Products with moisture above 15% risk microbial growth, while those below 10% become excessively hard and brittle. The sweet spot for senior chews is 12-14% moisture, achieved through precise humidity control during manufacturing and packaging with moisture scavengers rather than chemical preservatives.
Dosage Guidelines: Balancing Dental Benefits with Joint Support
The intersection of dental care and joint supplementation requires careful dosing consideration. A chew that’s too small may provide inadequate MSM, while one that’s too large could contribute to caloric excess and weight gain—anathema to joint health. The 2026 approach integrates precise caloric control, with each chew representing no more than 5% of a senior dog’s daily caloric needs.
Frequency matters as much as dosage. While daily administration is ideal for joint support, the mechanical cleaning action of dental chews is most effective when given every other day, alternating with tooth brushing. This “pulse dosing” approach may actually enhance MSM’s anti-inflammatory effects by preventing receptor desensitization that can occur with constant exposure.
Weight-Based Feeding Recommendations
Reputable manufacturers will provide detailed feeding charts that consider both weight and joint disease severity. A 50-pound dog with early-stage arthritis might receive one chew daily delivering 200 mg MSM, while the same dog with advanced disease might need two chews totaling 400 mg, with a corresponding reduction in other treats to maintain caloric balance.
These guidelines should also adjust for activity level. A sedentary senior needs fewer calories but may require the same MSM dose as a more active counterpart, as joint inflammation isn’t necessarily activity-dependent. Look for products that offer “maintenance” versus “therapeutic” feeding rates.
Frequency and Timing for Maximum Efficacy
Timing can optimize both dental and joint benefits. Giving the chew after the evening meal leverages the natural increase in salivary enzymes that occurs during digestion, enhancing the enzymatic cleaning action. The overnight fasting period that follows allows for optimal MSM absorption without competition from other nutrients.
For dogs receiving multiple joint supplements, coordinate timing to prevent interactions. MSM can be taken with or without food, but separating it from glucosamine supplements by 2-3 hours may improve absorption of both compounds. Many 2026 products include timing recommendations on packaging based on pharmacokinetic studies.
Emerging Trends in Functional Dog Chews for 2026
Personalization is the frontier of pet nutrition. Forward-thinking companies are developing “adaptive formulations” that can be customized based on your dog’s specific dental and joint health profile, submitted through a companion app. While mass customization is still emerging, the trend points toward acknowledging that a 12-year-old Labrador with hip dysplasia needs a different formulation than a 10-year-old Dachshund with periodontal disease.
Sustainability is no longer optional. Insect protein, cultured meat, and upcycled ingredients from human food production are reducing the environmental pawprint of premium chews. These novel proteins also offer hypoallergenic benefits for seniors who’ve developed sensitivities to common proteins over their lifetime.
Personalized Nutrition and Custom Formulations
The 2026 market is seeing the rise of subscription services that adjust MSM dosage and chew density based on quarterly dental assessments uploaded by owners. Using smartphone photos analyzed by AI, these services can detect changes in tartar accumulation and gum health, automatically modifying shipments to provide more or less intensive dental action as needed.
DNA testing integration is another frontier. Companies are beginning to offer chews formulated based on genetic predispositions to both dental disease and joint issues. A dog with genes indicating aggressive periodontal disease might receive chews with enhanced texture and antimicrobial ingredients, while a dog with collagen synthesis mutations receives higher MSM levels.
Sustainable and Ethical Sourcing Practices
Environmental sustainability directly impacts product quality. Insect protein, particularly from black soldier fly larvae, provides a complete amino acid profile with 90% less land use than traditional livestock. For joint health, these proteins are naturally rich in chitin, which converts to chondroitin-like compounds during digestion, providing synergistic benefits with MSM.
Marine-sourced MSM from algae rather than petroleum byproducts is gaining traction, offering identical molecular structure with renewable sourcing. Packaging innovations include compostable films made from cornstarch and algae-based inks, addressing the paradox of creating health products that harm the environment.
Red Flags: What to Avoid When Shopping
The functional chew market’s growth has attracted opportunistic manufacturers. Be extremely wary of products that list MSM far down the ingredient list—ingredients are listed by weight, and MSM should appear within the first five ingredients for therapeutic dosing. “Proprietary blends” that don’t disclose individual ingredient amounts are another red flag, preventing you from verifying adequate MSM content.
Avoid products making disease-treatment claims like “cures arthritis” or “reverses gum disease.” These are unapproved drug claims that violate FDA regulations and indicate either regulatory ignorance or deliberate deception. Legitimate products use qualified health claims like “supports joint health” and “helps reduce plaque buildup.”
Beware of extreme hardness claims. Products marketed as “indestructible” or “longest-lasting” often prioritize durability over safety, creating risks for tooth fractures and gastrointestinal obstruction. The goal is effective cleaning and supplementation, not replacing a bone as a chew toy.
Making the Transition: Introducing New Chews to Senior Dogs
Sudden dietary changes can disrupt senior dogs’ sensitive digestive systems. Introduce new functional chews gradually over 7-10 days, starting with a quarter-sized piece to assess tolerance. Monitor for changes in stool consistency, as MSM can initially cause loose stools in some dogs due to its mild detoxifying effects.
For dogs with severe dental pain, soften the chew in warm water for 30 seconds before offering. This reduces the initial mechanical challenge while still delivering MSM benefits. As gum health improves and pain diminishes (usually within 2-3 weeks), gradually reduce softening time until your dog can handle the full texture.
Cost Analysis: Investing in Preventative Care
Premium senior dental chews with MSM range from $1.50 to $4.00 per chew in 2026 pricing. While this exceeds basic dental chews, the cost-benefit analysis strongly favors investment. A single professional dental cleaning under anesthesia costs $500-1500, not including pre-anesthetic bloodwork often required for seniors. Joint injections like Adequan can run $40-80 per injection, with initial series requiring multiple doses.
When viewed as preventative care that may extend the interval between professional cleanings and reduce the need for more expensive joint interventions, functional chews represent sound financial planning. Many veterinary pet insurance companies are beginning to cover or subsidize VOHC-approved functional chews, recognizing their role in preventing costly diseases.
Frequently Asked Questions
How long does it take to see improvements in my senior dog’s mobility after starting MSM dental chews?
Most owners notice increased willingness to move and decreased stiffness within 2-3 weeks of consistent daily use. However, MSM works cumulatively, rebuilding cartilage matrix over time. Maximum benefits typically appear after 6-8 weeks. Keep a daily log of your dog’s mobility—difficulty rising, stair climbing, playfulness—to track subtle improvements that might otherwise go unnoticed.
Can dogs with kidney disease safely consume MSM in dental chews?
MSM is generally considered safe for dogs with compromised kidney function because it’s metabolized primarily in the liver and excreted through urine without significant renal processing. However, senior dogs with kidney disease should start with half the standard dose and be monitored for increased thirst or urination. Consult your veterinarian, who may recommend bloodwork after 30 days to ensure no adverse effects.
Will these chews interfere with my dog’s existing joint medications like Rimadyl or Galliprant?
MSM works through different pathways than NSAIDs and typically doesn’t cause drug interactions. In fact, some studies suggest MSM may allow for lower NSAID doses by reducing underlying inflammation. Never adjust prescription medication without veterinary guidance, but discuss the potential for dose reduction after 6-8 weeks of consistent MSM chew use if you observe improved mobility.
How do I know if the MSM dosage in a dental chew is therapeutic rather than just marketing?
Request the product’s certificate of analysis showing MSM content per chew. Therapeutic products will provide 50-100 mg MSM per 10 pounds of dog weight daily. If a company can’t provide this documentation or the amount is below 20 mg per chew for a medium-sized dog, it’s likely sub-therapeutic. Also check the ingredient list—MSM should appear among the first five ingredients.
Are MSM dental chews appropriate for dogs with few or no teeth?
Yes, but you’ll need to select appropriate formulations. Look for “senior soft” or “edentulous” versions specifically designed for dogs with compromised dentition. These soften quickly in saliva while still providing enzymatic cleaning action and full MSM dosage. You may need to break them into smaller pieces to prevent choking, but the joint benefits remain fully available through digestion.
Can puppies or young adult dogs use senior MSM dental chews?
While not harmful, these products are specifically formulated for senior physiology. The MSM dosage is calibrated for dogs already experiencing joint degeneration, and the texture is optimized for compromised teeth. Younger dogs benefit more from harder chews that provide greater mechanical cleaning and don’t require the high MSM levels. Use age-appropriate products for optimal results and cost-effectiveness.
How do MSM dental chews compare to water additives for dental health?
Water additives provide chemical antimicrobial action but no mechanical cleaning or joint support. They’re best used as adjuncts, not replacements. MSM dental chews offer superior plaque removal through physical abrasion and provide systemic anti-inflammatory benefits that water additives cannot. For senior dogs, the combination approach—chews plus appropriate water additives—provides comprehensive care.
What should I do if my dog experiences digestive upset when starting these chews?
Mild loose stools can occur as MSM begins to reduce systemic inflammation. Reduce the portion by 50% for one week, then gradually increase. Ensure your dog has constant access to fresh water, as MSM can increase thirst. If diarrhea persists beyond 48 hours or is severe, discontinue and consult your veterinarian. Some dogs may be sensitive to base ingredients rather than MSM itself.
Do MSM dental chews expire faster than regular chews due to the active ingredient?
Quality MSM remains stable for 24 months when properly stored. However, the overall chew may have a shorter shelf life due to natural preservatives and higher moisture content. Always check expiration dates, and once opened, store in an airtight container with the included moisture scavenger packet. Refrigeration can extend freshness but may harden the texture, so allow chews to return to room temperature before serving.
Will my dog build a tolerance to MSM, requiring increasing doses over time?
Unlike pain medications, MSM doesn’t cause tolerance or require dose escalation. Its mechanism involves providing essential building blocks and reducing inflammatory pathways, not receptor binding. Some dogs may need temporary dose increases during flare-ups or seasonal weather changes, but the maintenance dose remains consistent long-term. After 6-12 months of continuous use, some owners successfully reduce to every-other-day dosing while maintaining benefits.
