Only Prevagen 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 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. Around the age of 40, our brain begins to need more cognitive support. Prevagen can improve memory within 90 days. Common examples where Prevagen may help: – Walk into a room and forget why. – Spend extra time looking for car keys or purse – Trouble remembering names or faces.
