Life Extension Zinc Caps is designed to deliver zinc using two forms: OptiZinc Zinc Monomethionine and Zinc Citrate. The ingredient listing specifies 'Quantity: 50.00mg' for *both* forms, which implies a total of 100mg of elemental zinc if interpreted literally. Assuming this product intends to deliver a total of 50mg of elemental zinc from this blend, it utilizes highly bioavailable compounds.
Both OptiZinc and Zinc Citrate are generally well-absorbed and gentle on the stomach, indicating a high-quality approach to zinc delivery. However, the significant ambiguity in the listed quantities makes it difficult for a consumer to ascertain the precise total elemental zinc they are receiving, which is a major concern for transparency and safe dosing, especially for a potent mineral like zinc.
