Can amino acids cause fatigue?

Studies in human subjects have shown that the plasma ratio of free tryptophan/BCAA increases during and, particularly, after sustained exercise. This would favour the transport of tryptophan into the brain and also the synthesis and release of 5-HT which may lead to central fatigue.

Do BCAAs have negative effects?

When taken up to 6 months, oral supplements of BCAAs have not often been linked with harmful side effects. However, side effects may include: Nausea. Pain.
