ADVICE

Dietary Sources of C15:0

  • Include C15:0-rich foods in your diet, considering that its levels in dairy vary depending on the animal's feed.
  • Consider C15:0 supplementation, especially if blood tests reveal a deficiency.
INSIGHT

C15:0's Impact on Longevity Pathways

  • C15:0 activates AMPK and inhibits mTOR, both key pathways involved in longevity.
  • It also positively influences several other longevity pathways, including PPAR-alpha and AKT.
ANECDOTE

C15:0 Reverses Aging in Dolphins

  • A study on dolphins with lower C15:0 showed that increasing their intake through a C15:0-rich fish diet reversed age-related conditions.
  • This suggests a causal relationship between C15:0 and healthy aging.
