In this podcast episode of "Over 40 Fitness Hacks," host Brad Williams interviews Leslie Kenny from Oxford Healthspan to discuss spermidine and its potential to reverse gray hair. Brad, a personal trainer with over 14 years of experience, shares his own experience with hair loss and his interest in exploring solutions beyond conventional methods like finasteride.
Leslie explains the hair life cycle and how low spermidine levels, particularly after infections or during breastfeeding, can lead to hair shedding. She highlights the importance of spermidine in hair health and how aging and antibiotic use can affect its production in the body.
Leslie mentions promising results from clients using spermidine supplements, even in individuals over 90 years old with baldness. She emphasizes that while spermidine supplementation can help with hair growth, it may not fully restore hair in completely bald areas. The conversation shifts to dosage, with Leslie recommending a daily dose of 1 milligram, as per European Food Safety Authority guidelines.
She cautions against excessive doses of synthetic spermidine, citing potential negative effects observed in studies. Leslie also discusses the absorbability of spermidine supplements and the importance of quality over quantity.
In closing, Leslie provides information on where to find spermidine supplements and invites listeners to explore more resources on her YouTube channel and Instagram accounts. She also mentions her involvement in the Oxford Longevity Project, aimed at accelerating the translation of scientific breakthroughs in longevity to practical applications. Brad expresses gratitude for the insightful discussion, and the episode concludes with a promise to include relevant links in the show notes for listeners' convenience.
