Our Final Verdict
Natrol Cognium
Natrol Cognium is an unusual memory supplement built around silk protein hydrolysate (CERA-Q) — a proprietary compound with some clinical trials showing memory improvements in older adults. The research is real but narrow, and the formula is a single-ingredient approach. The Memory Wave uses theta-frequency audio entrainment to directly target the hippocampal brainwave state associated with memory encoding, delivering a neurological intervention rather than a nutritional one. For daily memory practice and recall speed improvement, the audio entrainment mechanism is more directly relevant.
