Evaluation of the Efficacy of Calcium a -Ketoglutarate(AKG-Ca) in Improving Human Aging

Description: Participants in the intervention group will receive oral calcium alpha-ketoglutarate (CaAKG) in granular tablet form. Each tablet contains 0.5 grams of CaAKG.Participants will take two tablets twice daily (morning and evening). The total daily dose is 2 grams. The intervention period will last for 12 weeks. CaAKG is a stabilized form of alpha-ketoglutarate that enhances bioavailability and provides supplemental calcium. The tablets are identical in appearance and texture to those in the placebo group to maintain blinding.

Participants in the placebo group will receive oral tablets identical inappearance and texture to the CaAKG tablets, but containing starch with no active calciumalpha-ketoglutarate. Each tablet weighs 0.5 grams. Participants will take two tablets twicedaily (morning and evening), for a total daily intake of 2 grams. The placebo tablets arepackaged and administered in the same manner as the CaAKG tablets to ensure blindingthroughout the 12-weekintervention period.
