PC (Phosphatidyl Choline) combines three forms of pure phospholipids for quick absorption to rebuild every cell in your body, benefitting every key system. PC contains concentrated levels of: Phosphatidylcholine (PC): essential for memory. Phosphatidylethanolamine (PE): vital to mitochondrial function. Phosphatidylinositol (PI): supportive to the brain and neurotransmission. Approximately 60% of the brain is fat. Low levels of phosphatidylcholine (PC) in the body impacts the brain and heart, affecting memory, mental alertness, behavior, and focus.
