Kirkman offers a special formulation of this dietary supplement often recommended by physicians based on laboratory testing results. Alpha-ketoglutarate is the salt-form of alpha-ketoglutaric acid. For example, calcium alpha-ketoglutarate is alpha-ketoglutaric acid bound to calcium. By itself, alpha-ketoglutaric acid is a strong organic acid, and taking it by mouth can upset the stomach or irritate the esophagus. Kirkman Laboratories has solved this problem by blending alpha-ketoglutaric acid with its calcium and magnesium salts to produce a "bi-element buffered alpha-ketoglutaric acid" which will not produce excess acidity. This nutrient can be taken with meals or away from meals. The hypoallergenic capsule can be swallowed or opened and the powder mixed with fruit juices or food. It has a pleasant, citrus-like taste.
