Glycine Side Effects
Even though it is a "natural" product, glycine can cause side effects. The commonly reported glycine side effects are generally minor and include nausea, vomiting, upper digestive tract discomfort, and mild drowsiness. However, potentially serious side effects of glycine can also occur. Contact your healthcare provider if you have symptoms of schizophrenia that are getting worse or develop signs of an allergic reaction while taking glycine supplements.

However, this is simply not the case. It is reasonable to assume that any supplement potent enough to have medicinal properties may also have side effects.
