The microbiome’s central role in aging gets a deep dive, including gut barrier health and postbiotics. Simple markers like fasting insulin, muscle mass, stool quality, and skin clues are highlighted. Practical, low-cost steps to slow biological aging and movement tips round out the conversation.

Discover which foods support stem cells, mitochondria, and gut lining to slow age-related decline. Learn how polyphenol-rich plants, greens, spirulina, mushrooms, and vitamin D fit into anti-aging strategies.
