Detailed Analysis
Taking valine with tryptophan may reduce tryptophan's ability to enter the brain and produce beneficial effects on mood and brain function. This is because valine competes with tryptophan for entry into the brain. As a result, tryptophan's effects may be diminished when taken with valine. Valine competes with tryptophan for entry into the brain by binding to the same transport proteins, potentially reducing tryptophan's effects. This competition is a result of both amino acids being large neutral amino acids that share the same transport mechanism across the blood-brain barrier.
