Starting my 3rd trimester, very low risk pregnancy. Curious about taking 500mg Niacin orally. Use Vitamin D3 and B12 for mild depression.

Category C drug. You a bodybuilder? LOL The "skinny" on this is that niacin is a vasodilator which is why bodybuilders love it (just ask Arnold). It ain't half bad lowering cholesterol as well. But it's labeled a Cat. C risk during pregnancy. That means harm to baby CANNOT BE RULED OUT, Probably safe up to about 18mg daily but best advice is to check with your doctor.
