    The InnerBuddies module "Longevity & Healthy Aging" gives you insight in:

    • Gut Microbiome & Short-Chain Fatty Acids (SCFAs)

      SCFAs contribute to anti-inflammation, gut health, and metabolic regulation, all linked to longevity. SCFA's functions as the base mechanism for the other categories. Butyrate gets high weight because of its robust evidence base in inflammation control, gut barrier integrity, and mitochondrial health — all critical for longevity. Propionate pathways are also key, especially for metabolic aging. Acetate is more abundant but generally has broader and more moderate effects; still important, especially as a substrate and signaling molecule.

    • Anti-Inflammatory & Immune Modulation

      Chronic inflammation accelerates aging; these pathways reduce inflammatory markers. Bile acids are among the most potent microbial immunomodulators with systemic relevance (gut-liver-brain axis, mucosal immunity). Tryptophan-derived indoles are among the most potent microbial immunomodulators with systemic relevance (gut-liver-brain axis, mucosal immunity). Polyamines offer both immunomodulatory and cell-protective benefits, especially in aging tissue. LPS and ammonia detox are supportive pathways—critical but more indirect in their effects.

    • Energy Metabolism & Mitochondrial Health

      Efficient energy metabolism supports cellular function, reduces oxidative stress, and enhances lifespan. TCA cycle and ETC dominate due to their centrality in mitochondrial health, bioenergetics, and ROS control — all of which are strongly linked to aging processes. Fat oxidation (FAO) supports metabolic flexibility, ketogenesis, and fasting states — overlapping with caloric restriction benefits. BCAA metabolism is double-edged: essential for mitochondrial function but excessive levels may promote mTOR activation and insulin resistance — balance is critical.

    • Cellular Repair, DNA Protection & Autophagy

      These pathways regulate DNA repair, cellular stress resistance, and autophagy, essential for longevity. Methionine / glutathione gets top weight for direct protection against oxidative stress, a primary driver of DNA damage. NAD⁺ biosynthesis is central to sirtuin-driven longevity mechanisms and DNA repair. Folate supports DNA stability but has more indirect or cofactor-like effects compared to the above.

    • Caloric Restriction & Fasting Mimicry

      Certain pathways mimic the benefits of fasting and caloric restriction, which are linked to lifespan extension.
