Eafit's 4: 1: 1 BCAAs are a food supplement based on BCAA (Branched Chain Amino Acid) which contains valine, leucine and isoleucine, the 3 amino acids known as “branched chain”, predominantly in muscle tissue. These amino acids are said to be essential because the body cannot synthesize them and they must be provided by food or nutritional supplements. The 4: 1: 1 ratio (4 Leucine to 1 Isoleucine and 1 Valine) is the actual ratio of muscle BCAA metabolism during training. This means that their absorption will be total. BCAAs are one of the 8 essential amino acids and constitute 35% of essential amino acids in muscle. This BCAA 4-1-1 is a source of vitamin B6 to help energy metabolism and reduce fatigue. It is advisable to take 6 capsules per day, preferably 3 capsules 1h30 before training or the test and 3 capsules 1h30 after training with a large glass of water, or as recommended by a professional trainer. Can also be consumed during a long test (more than 3 hours) at the rate of 2 capsules every hour for a surplus of energy. To be taken during periods of intensive training or competition over 20 days, to be renewed at least 20 days apart. Do not exceed the recommended dose. It is advisable to consume this supplement as part of a varied and balanced diet and a healthy lifestyle. Close well after opening. Keep out of the reach of young children.
