(1) Acetylcholine

Acetylcholine is one type of signaling molecule that is lower in Alzheimer's disease. Sea polyphenols have the potential to improve achetylcholine levels by blocking enzymes that degrade it (AChE and BuChE) [8,9,10]。

(2) Beta-amyloid

Another hallmark of Alzheimer's disease is the presence of abnormal protein clusters in the brain called beta-amyloid proteins. Sea polyphenols and Ecklonia cava extract may block the production of beta-amyloid [11,12], and also protect neurons from the damage and death caused by these abnormal proteins [13,14]。
