Cartilage Regeneration, Joint Pain, Nitric Oxide, Blood Flow, Muscle Strength & Longevity with Kiran Krishnan 

Host Dave Asprey sits down with Kiran Krishnan, research microbiologist, systems biology researcher, and co-founder of Microbiome Labs, to explore cartilage regeneration, joint pain, osteoarthritis, nitric oxide, vascular health, inflammation, muscle growth, gut health, bone density, and the biological mechanisms that influence how the body ages. 

Kiran Krishnan is a research microbiologist, health and wellness expert, and entrepreneur who specializes in the human microbiome, gut health, inflammation, and systems biology. Over the past 20 years, he has founded several successful health and supplement companies, including co-founding and leading Microbiome Labs, a leading microbiome therapeutics brand among healthcare professionals. He is also a co-founder and partner in three other health companies. Kiran has conducted and published scientific research, contributed chapters to scientific textbooks, holds global patents, and is a sought-after speaker on human health and the microbiome. 

His latest work explores the relationship between blood vessel health, chronic inflammation, and the body’s ability to repair damaged cartilage. Through research involving compounds designed to support vascular function, nitric oxide production, and joint health, Kiran is investigating whether age-related tissue degeneration can be slowed or potentially reversed. 

Dave opens the conversation by sharing his lifelong struggle with joint pain, including an arthritis diagnosis at age 14 and three knee surgeries. Kiran explains why cartilage degeneration may begin long before symptoms appear and how declining blood flow, damaged microvessels, and chronic inflammation can interfere with the body’s natural cartilage repair mechanisms. 

They explore the role of the endothelial glycocalyx, the protective lining inside blood vessels, and why nitric oxide production becomes increasingly important with age. Kiran explains how impaired circulation can affect everything from joint lubrication and cartilage health to cognitive performance, digestion, muscle recovery, and sexual function. 

Kiran also discusses research involving Cartigenix, a joint support supplement developed using compounds from Boswellia and celery seed. He describes clinical trials involving patients with osteoarthritis, including reported improvements in joint pain, inflammation, and cartilage regeneration, even among older adults with advanced joint degeneration. Dave and Kiran examine how Cartigenix, Arterosil, and Vascanox target different aspects of joint and vascular health, while distinguishing the Cartigenix trial results from the proposed benefits of combining all three products. 

The conversation then shifts to practical strategies for improving circulation and metabolic health. Dave and Kiran discuss why walking after meals may help regulate blood sugar, how the cephalic response prepares the digestive system for food, and why excessive endurance exercise may create trade-offs for recovery and long-term health. 

They also challenge conventional thinking about muscle growth and longevity. Kiran explains why functional strength may matter more than muscle size, how nitric oxide and microcirculation influence the delivery of amino acids to muscle tissue, and why maintaining healthy blood vessels could be an overlooked factor in preserving strength as you age. 

Finally, Kiran previews emerging research on bone regeneration, gut health, and a new postbiotic-based formulation being developed for bone health, particularly during perimenopause and menopause. He shares early findings involving bone repair and osteocyte production, while Dave explains why maintaining strong bones, healthy joints, and efficient circulation should be foundational priorities for anyone interested in longevity. 

This episode is essential listening for anyone interested in cartilage regeneration, osteoarthritis, chronic joint pain, nitric oxide, blood circulation, vascular health, inflammation, muscle growth, strength training, gut health, bone density, menopause, cellular repair, supplements, biohacking, and the science of maintaining physical performance as you age. 

You’ll Learn: 

• Why cartilage breaks down with age and how impaired blood flow and chronic inflammation interfere with joint repair 

• What Kiran’s clinical research suggests about cartilage regeneration and joint recovery in people with osteoarthritis 

• How nitric oxide and the endothelial glycocalyx influence circulation, cardiovascular health, cognitive function, and longevity 

• Why functional strength may be more important than muscle size for healthy aging, and how blood flow affects muscle growth and recovery 

• How walking after meals, supporting digestion, and improving vascular function may benefit blood sugar regulation and gut health 

• What emerging research suggests about bone regeneration, postbiotics, and maintaining bone density during menopause and aging
