Precautions

These supplements lower blood pressure to some degree, so anyone on blood pressure medicines, nitrates for angina, or erectile dysfunction medicines must check with a doctor first, since the combination can drop pressure sharply. They are not a treatment for heart disease or erectile dysfunction, and both of those deserve a proper medical assessment. Loose motions and stomach discomfort are the usual complaints at higher amounts.
