One of the best known and most effective ways to lower excess cortisol levels is with the nutrient Phosphatidylserine (PS). Phosphatidylserine is believed to facilitate the repair of the cortisol receptors in the hypothalamus. It is believed that the cortisol receptors get damaged by high cortisol levels reducing the ability of the hypothalamus to sense and correct high cortisone levels. Because Phosphatidylserine helps repair the feedback control apparatus, it is useful in correcting both high and low cortisol levels. Phosphatidylserine is also useful for preventing short-term memory loss, age-related dementia and Alzheimer’s disease.
