Betaine Increases Muscle Strength and Power

 A University of Connecticut, Storrs study found that 14 days of betaine supplementation (1.25 grams twice per day) increased muscle power and strength (bench press force, bench press throw power, vertical jump, and isometric squat) compared to a placebo (fake betaine). Betaine (also called trimethylglycine or TMG) is an amino acid compound found in wheat, spinach, shellfish, and sugar beets. It is an important regulator of body water and is useful in reducing levels of an inflammatory chemical called homocysteine, which is an important risk factor for coronary artery disease. Ranchers use betaine to increase muscle mass in domestic animals. It assists glutathione with detoxification reactions in the liver, and is useful for preventing depression.

 Betaine is an important human nutrient that is rapidly absorbed and utilized as an osmolyte (fluid regulator), and participates in amino acid reactions that help maintain liver, heart, and kidney health. TMG reduces blood levels of homocysteine and might improve athletic performance. (Journal International Society Of Sports Nutrition, 7: 27, 2010)
