Is cartilage regeneration possible with supplements? A double-blind, placebo controlled study using Cartigenix HP® with RestorCel®, suggests: yes.*†

For decades, consensus held that cartilage (the smooth, load-bearing tissue cushioning our joints) could not regenerate. However, emerging clinical research, including a human study with Calroy Health Sciences’ Cartigenix HP, challenges that assumption.*† 

Three studies show measurable improvements in pain scores, walking distance, and – in one placebo-controlled study – cartilage regeneration biomarkers.*† This supports the idea that targeted supplements can indeed support cartilage regeneration.*† 

This shift marks a new era in joint structure and function wellness, where functional medicine protocols and precisely formulated supplements provide credible, non-invasive tools for joint support.*

Understanding Cartilage Regeneration and Its Challenges

Articular cartilage is a specialized connective tissue covering the ends of bones in joints. It allows for smooth movement and absorbs mechanical stress. Yet, in part because cartilage has no direct blood supply, its natural repair capacity after injury is limited. This limitation, along with other biological factors associated with joints, fueled a longstanding belief that adult cartilage is unable to heal. This belief is now being challenged.*

Recent research showed that cartilage regeneration biomarkers (PIIANP and PIICP) improved with Cartigenix HP with RestorCel.*† Note: these biomarkers are specific to research, and will not be ordered by a healthcare provider.

For both practitioners and health-activated individuals, this represents an important advancement, showing that the proper combination of inputs may unlock previously untapped potential to maintain your joint health.*

Research Study: Supplement-Driven Regeneration with Cartigenix HP with RestorCel*†

A recent, double-blind, placebo controlled human trial directly measured cartilage regeneration using imaging and biomarkers. In this randomized trial, participants taking Cartigenix HP with RestorCel showed significant improvements within 90 days, including:*†

• 64% improvement in WOMAC pain scores
• 50% improvement in walking distance
• Increased cartilage regeneration biomarkers

Cartigenix HP was also researched in two other published, human studies. Across the three studies, participants experienced:*†

• Average 67% reduction in pain scores
• Average 50% increase in walking distance
• Noticeable improvements as early as day 15 for many participants

These studies mark a critical departure from earlier understanding of joint health support, which often focused on symptom management. They demonstrate that with the right blend of standardized bioactives, measurable improvements in cartilage regeneration were achieved.*†

Comprehensive, Whole-Person Interventions

Within functional medicine, joint health is best approached through coordinated, evidence-based care. A comprehensive protocol will likely include some or all of the following:

1. Science-backed supplementation – using formulas supported by human trials on the full formula, such as Cartigenix HP.*
2. Consistent weekly exercise – Regular movement is one of the most powerful levers for joint longevity. Activity circulates better blood flow to the synovial fluid, which is the liquid responsible for hydrating and nourishing the articular cartilage.
3. Joint-supportive diet – emphasizing whole foods high in antioxidants and polyphenols (think colorful vegetables, fruits, herbs, legumes, nuts) and include omega-3-dense foods (e.g., salmon, sardines, chia, walnuts)
4. Lifestyle support – Daily choices to support heart health, joint-focused eating patterns, movement, sleep, stress, and recovery. Learn the 6 top tips here.

A 90-day supplementation period aligns with observed biomarker changes in clinical studies on Cartigenix HP. A suggested timeline:

• Day 1 – Baseline assessment and supplement start
• Weekly, or Days 15, 30 and 45 – Check in and review (use the Joint Health and Mobility Tracker for easy, at-home progress monitoring)
• Day 90 – Evaluation of progress, recommend alternations based on results

Clinical oversight ensures personalized support, guided by measurable outcomes.

Recommendations for Effective Supplement Use and Monitoring

For best outcomes:

• Choose products supported by human data on cartilage biomarkers.
• Follow the clinically studied dosing and complete at least a 90-day protocol.
• Track progress with pain and mobility scores, walking tests, and where possible, imaging or biomarker analysis.
• Reinforce supplementation with optimal diet, consistent movement, and recovery practices.

Frequently asked questions

What supplements support cartilage regeneration or joint health?

Cartigenix HP has been evaluated in three published human trials, including a randomized, placebo-controlled study. In the studies, participants showed an average 67% reduction in pain scores and a 50% increase in walking distance within 90 days, with measurable cartilage regeneration biomarkers and noticeable improvements as early as 15 days.†

Key studies include:

• 2022 prospective study with 1236 participants
• 2024 observational human study with 394 participants
• 2025 randomized, controlled human study with 62 participants

Can cartilage really regenerate with the right nutrients?

A double-blind, placebo-controlled study with Cartigenix HP with RestorCel showed a statistically significant increase in cartilage regeneration biomarkers in 90 days.*† Across all three human studies with Cartigenix HP, participants also had an average 67% reduction in pain scores and an average 50% increase in distance walked.*

†As shown in a placebo-controlled, randomized, controlled human research study (Vaidya 2025) and an observational study (Desai 2024). A prospective study (n=1,236) similarly demonstrated significant improvements in pain scores, along with quality of life measures (Desai 2022).

How long does it take to see improvements with cartilage-regenerating supplements?

Clinical studies on Cartigenix HP with RestorCel show noticeable improvements within 90 days, though some study participants reported improvements in as little as 15 days.*†

What lifestyle factors support cartilage repair alongside supplementation?

Regular movement, stress management, and balanced nutrition all support cartilage health. Learn more daily tips to support joint health here.
