New Study Shows Omega-6 Fat Arachidonic Acid Builds Muscle
LAS VEGAS, July 11, 2014 /PRNewswire/ -- Molecular Nutrition (MN) announced today clinical study results for their X-Factor™ arachidonic acid (ARA) supplement. Under controlled conditions in the University of Tampa's Human Performance Research Lab, supplementation of ARA for eight weeks significantly increased lean body mass, muscle thickness, strength, and anaerobic power in experienced resistance-trained men. These findings were unveiled at the National Strength and Conditioning Association (NSCA) conference in Las Vegas, NV.
Arachidonic acid is an omega-6 fatty acid. It is found in many foods including eggs, beef, chicken, and fish. ARA is one of the most biologically important fatty acids; playing key roles in the immune system, memory and learning, bone mineral density, and cardiovascular health. MN CEO William Llewellyn first proposed that supplemental ARA would support skeletal muscle growth more than a decade ago. This study validates his original hypothesis, and provides very clear support for the use of ARA supplements in sports.
Thirty college-aged men were recruited for the study, and randomized into two groups. The men in the first group were given 1,500 mg of ARA daily, and the other an identical-looking placebo. All men followed a periodized resistance-training program for 8 weeks. At the end of the study, the group supplementing ARA reported significantly greater gains in lean body mass (3.6 lbs. vs. 0.2 lbs.). They also noticed an 88% greater increase in muscle thickness (.47 cm vs. .25 cm), and added significantly more strength to bench press and leg press (110 lbs. vs. 76 lbs.). Lastly, wingate peak anaerobic power was dramatically improved with ARA (78W vs. 28W), a 275% greater increase.
"This study has demonstrated in a controlled setting the type of remarkable results we've noticed with athletes and bodybuilders for many years now," said William Llewellyn. "Arachidonic acid is a key link between the mechanical stress of resistance training, and the biological repair process that comes in afterwards to facilitate protein synthesis and growth. This gives us an exceptionally effective opportunity for increasing muscle mass and strength. ARA supplementation should provide a distinct advantage for bodybuilders, and athletes in all sports where strength and power are decisive variables."
