NOW Foods Phosphatidylserine 300 mg (50 softgels) is a supplement with 300 mg phosphatidylserine per softgel, derived from highly refined soy lecithin. Phosphatidylserine is a fatty substance that naturally occurs in food and is commonly used in supplements. The softgels also contain MCT oil (medium chain triglycerides) as a base, making the fat-soluble substance easier to absorb. This extra strong variant contains three times as much phosphatidylserine per softgel as the standard 100 mg variant. The formula is suitable for anyone wanting a higher dosage with the convenience of use. The recommended dosage is 1 softgel per day, taken with a meal.
