References and Source Methodology

What our references mean

Each page uses links to the source documents most relevant to its claims. Seller sources establish what the seller presently advertises, while government and peer-reviewed sources provide independent background or ingredient-level research.

No reference to an ingredient study should be read as a randomized clinical trial of the finished PhytoMem One formulation unless explicitly stated.

Checking source recency

Seller pages can change by offer version and date. Review purchase details at the time you buy. Scientific findings may also be revised as new controlled research appears.

We distinguish an observed price snapshot from a guarantee and a published ingredient study from an established finished-product result.

Core source collection

The linked catalog below includes FDA supplement guidance, NCCIH cognitive-supplement reviews, NIA brain-health information, seller policy documents and selected PubMed research. Sources are listed for transparency, not to suggest endorsement by those institutions.
