Calcium alpha-ketoglutarate (Ca-AKG) is a calcium salt of alpha-ketoglutarate, a key intermediate in the Krebs cycle involved in cellular energy production. It gained attention in the longevity space after a 2020 mouse study showed significant lifespan extension and reduced frailty. AKG levels naturally decline with age, and supplementation aims to restore them. Human clinical trials are still in early stages. The "calcium" in Ca-AKG refers to the mineral salt form, not an additional calcium supplement — though it does contribute a small amount of dietary calcium. Products below are ranked by cost at your chosen daily dose.

This is the current ranking surface for Ca-AKG (Calcium Alpha-Ketoglutarate). It recalculates cost per month from product price, Supplement Facts active amount, servings per container, and the dose you enter above.
10 active products have enough price and label data to calculate cost before display filters; 10 rows are currently shown in the ranked table. The current review floor for this category is 10+ reviews before any large-category and duplicate/bulk filtering.
At 1000 mg/day, visible products range from $14.99-$25.95/mo with a $20.68/mo median midpoint and a 1.7x low-to-high spread.
Look for Calcium Alpha-Ketoglutarate or Calcium AKG on the Supplement Facts panel. Labels checked for this update showed 300 mg, 700 mg, 1000 mg, and 1500 mg Ca-AKG servings, with serving sizes ranging from 1 capsule to 3 capsules or 1 scoop.
The biggest cost differences come from labeled Ca-AKG per serving, servings per container, and delivery format. Liposomal capsules, time-release capsules, and powder can rank very differently once normalized to the same daily dose.
Do not treat A-AKG, OKG, GKG, or nitric-oxide booster blends as Ca-AKG just because the title contains similar AKG language. Those are different label lines and should not be ranked as Calcium Alpha-Ketoglutarate products.
Ca-AKG remains an emerging-evidence category. The rankings compare the labeled Ca-AKG amount and current price; they do not validate longevity, anti-aging, liposomal, or time-release claims.
