Tag: Excess isoleucine

While isoleucine is a vital essential amino acid for muscle health, studies have demonstrated that excessive intake can have notable disadvantages, especially related to metabolic function. Excessive consumption of this branched-chain amino acid (BCAA) can lead to potential health concerns beyond simple benefits, making it crucial to understand the risks.

In a 2021 study in the journal *Cell Metabolism*, researchers highlighted that increased dietary isoleucine levels are associated with a higher Body Mass Index in humans. These findings and other research suggest that having too much isoleucine can lead to significant health complications, including metabolic and neurological issues, though this is rare through diet alone.
