Folch and the brain
The Spanish-American biochemist Jordi Folch-Pi isolated phosphatidylserine in 1941 from bovine brain tissue. For a long time, phosphatidylserine for supplements also came from bovine brains. After the BSE crisis, manufacturers switched to plant sources, mainly soy lecithin.
Made in the United States
Doctor's Best uses SerinAid®, phosphatidylserine from soy, made by the Italian company Chemi Nutra. The capsule is plant-based. The product contains soy.
Facts about this product

Phosphatidylserine with SerinAid by Doctor's Best
Doctor's Best Phosphatidylserine SerinAid® contains the brain nutrient phosphatidylserine combined with other phospholipids. Phospholipids are fatty substances important for the construction of cells. Phosphatidylserine is highly abundant in oily fish. People who appreciate the beneficial properties of oily fish often choose a phosphatidylserine supplement. People of age also often choose this supplement.
Benefits
100 mg of phosphatidylserine per capsule. Patented SerinAid®. Does not contain gluten; GMO-free. Suitable for vegans and vegetarians.
Serine
Serine is one of the twenty natural amino acids. The non-essential amino acid is formed in the body from other metabolites, such as the amino acid glycine. Phosphatidylserine is a phospholipid to which serine is bound. This Doctor's Best product contains SerinAid®, a registered, high-quality form of phosphatidylserine.
Phospholipids
A phospholipid is a fatty substance, or lipid, consisting of a phosphate group, a glycerol group, a nitrogen-containing alcohol group and two long fatty acid tails. Different types of small molecules can be attached to the phosphate group, such as serine or choline. Phospholipids are structural lipid-protein complexes that bind together to form a membrane around every cell in the body. Much is still unknown about the effect of phospholipids in the body. The metabolism of phospholipids is impressive, however. More research is needed, however, to understand what exactly the role of phospholipids is after ingestion and how they interact with the various processes in our complex metabolism.
Phospholipids in lecithin
Phospholipids are common in the body and are therefore very essential. Since the early twentieth century, the beneficial effects of dietary phospholipids have been regularly mentioned. An important source of phospholipids is lecithin, which is found in egg yolks, soybeans, sunflower seeds and rapeseed. Lecithin is often added to certain foods as a natural emulsifier. The most common phospholipids in food are phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and phosphatidylserine. Phospholipids are also sometimes used in foods as antioxidants.
Dietary sources of phospholipids
All plant and animal foods contain phospholipids. The concentration and composition of food phospholipids vary depending on the food source, for example animal or vegetable. Phospholipids from cold water fish, for example, mainly contain unsaturated omega-3 fatty acids. Phospholipid concentrations can also increase during drying of milk or whey, for example. Animal sources of phospholipids include eggs, milk, meat and fish, seafood and krill oil. Vegetable seeds, grains and wheat starches are also rich sources of phospholipids. Finally, phospholipids are present in certain fruit and vegetable products such as spinach, orange juice and lemon juice.
