Major heat, flushing, and itching! Beware!
Beware! I took one pill, and about 30 minutes later, I thought my body was on fire! The flush, itching, and heat started on my face and then went to the rest of my body. I will not take it again, but this is not a returnable item.

Not a fan of this niacin
My spouse and I each took 1 of these niacin pills. In about 30-40 minutes, we both had a reaction. I expected the flush, but not the intense heat, tingling, intense scalp itching along with arms and legs, light headedness and low blood pressure. 85/50 is a bit too low. I have taken niacin supplements before and had a flush but nothing near this. We won’t be taking anymore.
