Product Details The body produces creatine primarily in the liver and kidneys from the amino acids arginine and glycine, with help from S-adenosylmethionine. Creatine circulates through the bloodstream to help support energy for cells throughout the body, but healthy levels tend to decline as we age. 1 Lean muscle mass, exercise performance and recovery Creatine is one of the best-studied nutrients for lean muscle mass, strength, and power. It is a staple of both professional and amateur athletes, and a must-have for almost any regular exercise routine. 2,3 Cellular energy production Creatine helps cells produce their primary source of energy, ATP (adenosine triphosphate), which is essential for supporting an array of biological processes that keep you healthy. In the body, creatine helps recycle ATP to create energy that cells can use. Creatine and women Women have 70-80% lower internal creatine stores than men and may consume lower dietary amounts of creatine. And during times of hormone-related changes, creatine kinetics may be altered in the body. Creatine supplementation may help improve strength and exercise performance throughout these changes, in both pre- and postmenopausal women. 4,5 Creatine as you age Numerous clinical trials have demonstrated creatine has positive effects on upper and lower body strength, physical performance, and body composition and supports muscular performance in older adults, especially when combined with resistance training, with best effects generally seen after 12 weeks. 3,5-7 Add this easy-mix, unflavored powder to eight ounces of water, a protein smoothie or your preferred beverage.
