ARA powder is in white or light yellow color.ARA powder is water soluble and easy to form stable emulsion.It utilizes the unique microencapsule technology to encapsulate and stabilize submicro-sized droplets of ARA in a water-soluble shell. The production process is controlled strictly by HACCP. The product has excellent cold-water-solubility and flowability.
Arachidonic acid (AA, sometimes ARA) is a type of omega-6 fatty acid that is involved in inflammation. Like other omega-6 fatty acids, arachidonic acid is essential to your health. Omega-6 fatty acids help maintain your brain function and regulate growth. Eating a diet that has a combination of omega-6 and omega-3 fatty acids will lower your risk of developing heart disease. Arachidonic acid in particular helps regulate neuronal activity.

Function:
1)Muscle Growth:
ARA is an important dietary component in support of the muscle anabolic process.
Arachidonic acid is a regulator of localized muscle inflammation,and may be a central nutrient controlling the intensity of the
anabolic/tissue-rebuilding response to weight training.
2). Alzheimer's Disease
Supplementation of arachidonic acid during the early stages of this disease may actually be effective in reducing symptoms and
slowing the disease progress.
3). Brain
Arachidonic acid is one of the most abundant fatty acids in the brain, and is present in similar quantities to docosahexaenoic acid (DHA). 
Arachidonic acid helps tomaintain hippocampal ,cell membrane fluidity and helps protect the brain from oxidative stress by activating peroxisome
proliferator-activated receptor gamma.
4). Bodybuilding Supplement
Arachidonic acid is marketed as an anabolic bodybuilding supplement in a variety of products.
