What the source establishes

The JECFA entry identifies the additive as INS 511 and names magnesium chloride hexahydrate. A food-additive function describes what an ingredient does in a food-making context. [1]

The historical evaluation record includes an acceptable-daily-intake classification and links to specifications. Those fields belong to an evaluated use and specification system; they are not a personal supplementation prescription. [1]

What it does not establish

The name on a sack of industrial material does not demonstrate compliance with food specifications. Likewise, an additive listing does not establish sleep, muscle or other clinical benefits. Finished-product grade, composition and intended use remain separate questions. [1]

A hypothetical distinction

Imagine two materials share a chemical name but are sold for different purposes. The name identifies chemistry; documentation establishes the applicable specification.
