A study showed Phosphatidylserine enhanced mood in a cohort of young people during mental stress and to improved accuracy during tee-off by increasing the stress resistance of golfers.[1]

PET imaging of a 59-year-old woman’s brain showed taking 500mg of Phosphatidylserine daily for three weeks increased metabolism in almost all brain regions.[2]

Phosphatidylserine is a component of the cerebral cortex’s neuronal membrane,[3] and helps restore your brain's supply and output of acetylcholine, a neurotransmitter essential to memory.[4] It also helps restore your brain's supply and output of dopamine, which is essential to memory, attention and problem-solving.[5]-[11]

Phosphatidylserine has been shown to enhance mood in a cohort of young people during mental stress.12 One study found preliminary evidence that a combination of soy-based Phosphatidylserine and lecithin may moderate the body's reaction to mental stress.[13]

Phosphatidylserine has also ameliorated elevations of stress hormones associated with strenuous exercise in young men.[14],[15]

Researchers at the University of Milan conducted a study of 10 women with depression, aged 70 to 81 years, and found Phosphatidylserine increased brain turnover of norepinephrine, dopamine, acetylcholine and glucose reserves. Using the Hamilton Rating Scale for Depression (HRSD) and clinical observation, the researchers found treatment with Phosphatidylserine, compared with pre-treatment baseline scores and controls, caused anxiety levels to decrease while improving long-term memory and learning.[16]

Each serving of Elebra contains 100mg of soy-derived Phosphatidylserine, and is manufactured in the USA at a cGMP facility that has an "A" rating (the highest possible) from the National Nutritional Foods Association. We stand behind our product and offer a 100% Money Back Guarantee.
