Chronic supplementation with 15 g/day of essential amino acids (EAA) increases lean body mass and basal muscle protein synthesis in older women.

If you are an older woman experiencing muscle loss, consider taking 15 grams of essential amino acids daily, split into two doses between meals. This simple nutritional strategy can help increase your lean body mass and muscle protein synthesis, potentially counteracting age-related muscle loss.

GoodSupportsHIGH confidence
EAA improved LBM and basal muscle protein synthesis in older individuals. The acute anabolic response to EAA supplementation is maintained over time and can improve LBM, possibly offsetting the debilitating effects of sarcopenia.
