Evidence LevelEmergingStrong

Mechanism

Odd-chain saturated fatty acid identified as essential. Strengthens cell membranes by integrating into phospholipid bilayer, activates AMPK and PPAR-alpha/delta, and inhibits mTOR. Repairs mitochondrial function. Epidemiologically associated with reduced cardiometabolic disease.

Contraindications

  • None established

Mechanism

Isothiocyanate that activates Nrf2 — the master regulator of antioxidant defense. Upregulates glutathione synthesis, phase II detoxification enzymes, and heat shock proteins. Also inhibits HDAC (epigenetic modifier) and NF-kB (anti-inflammatory).

Contraindications

  • Thyroid conditions (goitrogen at very high doses)
  • Cruciferous vegetable allergy
