Huperzine A improved cognition

In this study, 78 people with vascular dementia, a type of impairment from reduced blood supply to the brain, took 100 mcg of huperzine A, or a placebo containing 100 mg of vitamin C, twice per day. After 12 weeks, while the placebo group had not improved, the huperzine A group performed better in mental tests, had improved ratings for clinical dementia, and better quality of daily living activities. Huperzine A is a naturally occurring compound from the Chinese club moss, used in China as a traditional medicine.

 

Phospholipids improved memory

Under sudden stress, the adrenal glands release cortisol to give a quick burst of energy, sharpen memory, and decrease sensitivity to pain. But when stress is chronic, cortisol can have negative effects, including impaired memory. Doctors believe phospholipids help the body adapt to stress.

In this study, 75 chronically stressed men, aged 30 to 51, drank cow’s milk with 0.5 percent or 1.0 percent phospholipids per day, or a placebo. After six weeks, while there was no difference between any of the groups in response to acute stress, men over age 41 in the high-dose¬†phospholipid group had better memory performance.
