    What the source establishes

    The NCI Drug Dictionary identifies retinyl acetate as an ester form of retinol. It lists vitamin A acetate and retinol acetate as synonyms. [1]

    The entry also describes potential biological and anticancer activities. Such dictionary language describes a research context; it is not a clinical trial showing that an ordinary supplement prevents or treats cancer. [1]

    What it does not establish

    The name alone does not establish whether a finished product is vegan, its dose or the source of its other ingredients. Those questions require product-specific evidence. An ingredient dictionary cannot substitute for a complete label or a treatment assessment. [1]

    A hypothetical distinction

    Imagine two packages use synonymous chemical names. That can establish an ingredient match while leaving concentration, other ingredients and intended use unresolved.
