Phosphatidic Acid Ingredient May Increase Strength and Muscle Mass

Chemi Nutra (White Bear Lake, MN) has published what it believes is the first clinical study to investigate phosphatidic acid supplementation for exercise performance. Researchers believe that phosphatidic acid can stimulate mammalian target of rapamycin (mTOR), which may be necessary for mechanical load-induced growth of skeletal muscle and resulting strength gains.

During an eight-week resistance-training program, 20 young men were assigned to 750 mg of Monitor phosphatidic acid or 750 mg of a rice flour placebo daily. Subjects were instructed to perform one maximum repetition of a bench press and leg squat to assess maximum strength. Body composition and diet was evaluated daily.

Compared to placebo users, subjects who consumed Monitor phosphatidic acid demonstrated significantly increased squat strength, bench press strength, and lean muscle (an increase of 2.6% compared to 0.1%).

Chemi Nutra’s study is now published in the Journal of the International Society of Sports Nutrition.
