What is Ginkgo Biloba Extract? It is made by drying ginkgo leaves and soaking them in water or ethanol to extract the components. Ginkgo leaves contain more than 30 kinds of flavonoids, ginkgolides, and bilobalide, which are terpenoids. Ginkgo is said to have appeared about 250 million years ago. What is Soy Lecithin? It is lecithin derived from soybeans and is also called phosphatidylcholine. Lecithin is a type of phospholipid also found in egg yolks and yeast. It is also present in the human body as a major component of biological membranes such as cell membranes, the brain, and nerve tissue. Therefore, it is expected to be a nutrient for the brain. In addition, lecithin has both a water-friendly (hydrophilic) part and an oil-friendly (lipophilic) part in its structure, so it can mix water and oil, and is also used as an emulsifier.
