Is American ps natto a scam?

PS natto is a compound enzyme biological preparation approved by FDA, and its English name is phosphatidylserine, or PSNK for short. The main components of its patented formula are PS (phosphoserine) and NK (nattokinase). PS natto has strong lipophilicity, can pass through the brain barrier for 45 minutes, reduce blood lipid, dissolve thrombus, repair hardened blood vessels, dissolve Alzheimer's plaque and increase blood supply to the brain. At the same time, it can replenish phosphatidylserine (PS) to brain cells in time, increase neurotransmitters in brain tissue, restore normal memory function of brain, restore brain atrophy, and end Alzheimer's disease. Natto products are only composed of single natto powder and nattokinase, which only has a single thrombolytic and lipid-lowering effect, and can not repair cerebrovascular disease, restore memory, nourish brain tissue and restore brain atrophy. Last year, I bought it for my family in official website, the mainland of PS Natto. It's quite good.
