Calcium Alpha-Ketoglutarate (Ca-AKG) vs Inositol (Myo-Inositol + D-Chiro-Inositol)

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

Calcium Alpha-Ketoglutarate (Ca-AKG)Inositol (Myo-Inositol + D-Chiro-Inositol)
CategorySupplementsSupplements
Standard Dose
Timing
Cycle Duration
Evidence LevelModerate (healthspan), Emerging (human longevity)Strong (PCOS, anxiety), Moderate (general metabolic)

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

Secondary messenger in insulin signaling cascade. Myo-inositol improves insulin sensitivity, reduces anxiety (via serotonin receptor modulation), and supports ovarian function. D-chiro-inositol complements by activating glycogen synthesis. 40:1 ratio mimics physiological balance.

Contraindications

  • Bipolar disorder (inositol depletion theory — consult psychiatrist)
