Question: My son is in ROTC and consumes protein drinks to supplement his food intake. He throws up bile almost every morning of training. Is this because of the protein drinks?

Dr. Blaylock's Answer:

Muscles use branched chained amino acids (BCAAs) for structural building. The amino acids from “protein drinks” such as glutamate, cysteine, and aspartate are excitotoxins and can result in injury to certain areas of the brain.

The body can easily absorb BCAAs and utilize them for muscle building. High-protein diets put a lot of stress on the kidneys. As for the vomiting of bile, he needs to have a gastrointestinal work-up to make sure there is no disease at play. DGL Plus (Pure Encapsulation) soothes the stomach and esophagus and may help until he can be seen by a doctor.
