Doctor's Best Fast Acting Arginine Complex w/Nitrosigine, Boost Nitric Oxide, Blood Flow & Vessel Flexibility, Non-GMO, Vegan, Gluten Free, 750mg, White (DRB-00406)

Best arginine supplement I've tried. Very fast acting.

I think it helped give me more flow in my feet after blocked artery detected

Very effective. Not pain relieving but definitely promotes energy. Little spendy for the amount you get though.

Because I use a lot of supplements, it’s important for me to pay attention to cost and value and side effects. This is a brand I use often because there are fewer side effects and they usually carry a strength and effectiveness that works for me. you won’t be disappointed if you buy this brand.

It seemed to work but gave me bad night sweats - totally soaked sheets and pillow cases with the AC on. I've tried many arginine blends with varying results, but the Nitrosigine was bad for me. Your experience may differ. The sweats cleared up as soon as I stopped taking it and never came back.
