Prevagen Extra Strength contains the ingredient apoaequorin, a unique protein originally obtained from a specific species of jellyfish called Aequorea victoria found in the Puget Sound. Apoaequorin is a protein our brains need for healthy function but is diminished in the aging process. Prevagen is very safe and extremely well-tolerated. There are no known contraindications with any supplements or medications. Prevagen Extra Strength has twice the amount of apoaequorin when compared to the original strength Prevagen. Prevagen was tested in a large double-blind, placebo-controlled study using computers to assess brain performance. 218 adults over 40 years old participated in the three month study. Prevagen significantly improved learning and word recall. Prevagen has been shown to improve memory within 90 days.
