Optimum Nutrition BCAA 1000 Caps Review

Optimum Nutrition BCAA 1000 Caps are branched chain amino acid food supplement capsules positioned for active lifestyles. The product is recommended first thing in the morning and or during the 30 minutes just before or immediately after training. The suggested use is to take 2 capsules with your favourite beverage or with your protein shake. Each 2 capsule serving delivers 1000 mg of BCAAs in a 2:1:1 ratio of L-Leucine, L-Isoleucine and L-Valine. The page describes the capsules as easy to swallow and says they can be used between meals, before training, or after finishing a workout to augment daily intake of amino acids. It is listed in 60 capsule, 200 capsule and 400 capsule sizes, with the 60 capsule bottle equal to 30 servings. The page also markets it with the phrase Essential Amino Acid Support and Versatile Amino Acid Support. The current listed price for the 30 serving size is $12.49 with a price per serving of $0.41, and a subscription option offers 20 percent off with flexible delivery schedules. The product is described as a supplement that supports your active lifestyle and augments daily intake of amino acids, and it should not be used as a substitute for a varied diet. Food supplements should not exceed the recommended daily dose and should be kept out of reach of children. The page includes a nutritional information label image for the 60 capsule and 30 serving bottle. Customer questions address the gelatin source of the capsules, with the brand confirming that the gelatin is bovine or porcine as supplied. The page presents the product as a simple, portable option for those who want to take amino acids in pill form rather than mixing powders, and it notes that the capsules are a convenient way to ensure the amino acids are fully ingested.
