Side-by-side comparison of mechanisms, dosing, interactions, and stacking potential.

CategorySupplementsSupplements
Standard Dose
Timing
Cycle Duration
Evidence LevelModerate (healthspan), Emerging (human longevity)Strong

Mechanism

AKG is a TCA cycle intermediate that declines with age. Supplementation reduces inflammatory cytokines, improves stem cell function, and extends healthspan in mice. Calcium salt form provides sustained release. Also supports collagen synthesis and reduces frailty markers.

Contraindications

  • Hypercalcemia
  • Kidney stones (calcium component)

Mechanism

Endocannabinoid-like lipid that activates PPAR-alpha and indirectly enhances endocannabinoid tone. Potent anti-inflammatory and analgesic without acting directly on CB1/CB2. Reduces mast cell activation, neuroinflammation, and chronic pain.

Contraindications

  • None established at standard doses
