ProHealth, Ca AKG Supplement (Alpha Ketoglutarate)…

Our verdict

ProHealth, Ca AKG Supplement (Alpha Ketoglutarate)… works out to $0.70 per serving of alpha-ketoglutarate (akg), at 1000mg per serving in capsule form. That puts it above the median of the 6 alpha-ketoglutarate (akg) products we can price per dose, where the typical serving costs $0.19. One container lasts 90 days at the label dose of 1 serving a day, about $21.12 a month. We could not verify a third-party certification for ProHealth in a public registry. Worked out from the current retail price as of 2026-11-13; confirm the live price on Amazon.com before buying.
