â¢ BCAAs play an important role in muscle and energy production during exercise, which is the reason that they are often used during workouts. â¢ BCAAs convey many health benefits and a higher dietary intake has been identified as a predictor of longevity.
Further research is needed to determine valineâs role in a BCAA supplement. Supplementing BCAAs prevents a serum decline in BCAAs, which occurs during exercise. A serum decline would normally cause a tryptophan influx into the brain, followed by serotonin production, which causes fatigue. BCAAs are important to ingest on a daily basis, but many protein sources, such as meat and eggs, already provide BCAAS. Supplementation is unnecessary for people with a sufficiently high protein intake (1-1.5g/kg a day or more).
