Although L-arginine may be safe when taken in the short-term, it can cause a number of side effects (including indigestion, nausea, headache, bloating, diarrhea, gout, blood abnormalities, allergies, airway inflammation, worsening of asthma, and low blood pressure).
Supplemental amino acids are generally regarded as safe, but watch out for potential side effects from arginine and methionine. Also be aware that branched-chain amino acids could upset the balance of neurotransmitters.
