Calcium AKG Longevity Capsules

Key Benefits

• Source of calcium, which contributes to normal energy-yielding metabolism.

• Calcium contributes to the maintenance of normal bones and teeth.

• Provides calcium in the form of calcium alpha-ketoglutarate.

Calcium AKG Longevity Capsules deliver 200 mg of calcium per serving in the form of calcium alpha-ketoglutarate (Ca-AKG). This formulation combines calcium with alpha-ketoglutarate, a compound naturally present in the body and involved in cellular processes.

Calcium contributes to normal energy-yielding metabolism, normal muscle function, and normal neurotransmission, while also contributing to the maintenance of normal bones and teeth. Each serving provides a source of calcium to support daily nutritional intake.

Encapsulated in vegetable cellulose with a simple ingredient profile, the formula remains free from dairy, gluten, soy, corn, fish, shellfish, tree nuts, and peanuts. The two-capsule daily format offers a straightforward way to include calcium as part of a balanced routine.

Calcium AKG Longevity Capsules use alpha-ketoglutarate (AKG) bound to calcium rather than left unbound or attached to arginine. This form has featured in animal research exploring lifespan and health span, including studies in mice later in life. Binding AKG to calcium also influences how the compound moves through the body, supporting a steadier absorption profile. Manufacturing takes place in an FDA-registered, GMP-certified facility to maintain consistent quality standards. Each batch undergoes third-party testing in US laboratories to verify purity and potency.
