Supplement Spotlight: Phosphatidylserine

9 Jul

Phosphatidyl Serine (PS) is a rather potent brain nutrient that causes a calming effect due to lowering the ‘fight-or-flight’ system. It acts to lower the stress hormone cortisol at the wrong time of day. If you find yourself restless and unable to fall asleep, your stress hormone may be out of control.

It’s also especially effective for minimizing cognitive decline that occurs with age, and it has even been shown to improve your golf game by calming the mind under stress! It has also been shown to significantly decrease ADHD symptoms, especially when paired with sufficient omega-3s. This is because it works to support specific neurotransmitters in the brain, such as dopamine, serotonin, acetylcholine, and norepinephrine.

Studies have shown that 600 mg for 10 days yielded significant effects on lowering cortisol after high-intensity intervals, more favorable testosterone to cortisol ratio than a placebo group. Another study demonstrated that 400 mg of PS significantly decreased cortisol and led to lower activation of the pituitary adrenal axis (another measure of stress) in comparison to a placebo after a social stress test.

3-4 capsules (150 mg each) of PS in the afternoon is recommended. At FIT, we currently carry phosphatidylserine as well as other nutraceuticals that may be the missing support to your fitness program. Feel free to ask Jeff P. if you have any questions!
