FDA labelling on BCAAs?

So I just bought my first tub of BCAAs in awhile (Man Sports Iso Aminos) and there is a new label on it that says "Do not take if you are on antidepressants." It has the same exact ingredients as it used to have (L-Leucine, L-Isoleucine, and L-Valine), yet the labelling is different. I reached out to the company to ask why, since I am on antidepressants and wanted to make sure it was safe because I have taken them before with no ill effects. All they said was that the FDA required them to have that label. Does anyone know why? I did some research, but am still not understanding how antidepressants could interact in any way with the amino acids included in this BCAA.
