Rosemary Extract and Acetylcholine: How It Works, Explained

A Long Traditional Reputation, Now Being Tested Formally

Rosemary (Rosmarinus officinalis) has a long history of traditional use tied to memory, and modern research has begun testing that reputation more formally.

What the Research Shows

A controlled study in university-aged adults found that rosemary supplementation had measurable effects on both prospective and retrospective memory performance compared to placebo. A separate dosing study in older adults measured cognitive performance across a range of doses.

The Acetylcholine Connection

Researchers believe rosemary's compounds, including rosmarinic acid, may help preserve acetylcholine, a neurotransmitter associated with learning and memory formation.

The Important Caveat

A broader review of the literature found consistent cognition-related effects across species and extract types, though the review's authors also noted that more rigorous, larger human trials are still needed.

Bottom Line

Rosemary Extract in CogniMary is included as part of the formula's memory-support foundation, working alongside three other ingredients.
