Consistently Awesome!

Because I wont take any Rx toxins for anything, but rather chose suppliments as my only alternative, the money I save buying from Bulksupplements is phenomenal! And then there is the awesome customer service on top of that! The purity and consistency of everything I have ever purchased from Bulksupplements still gives me the warm and fuzzies when I open up my delivery. I really appreciate this great company!

Great Value!!

Best value on Amazon, or any other website for that matter. I talk Niacin daily for anxiety, and it makes a huge difference. I started out low and slowly bumped it up till I found a good daily dose. Tablets or capsules can be easier for getting an exact amount, but this powder is a way better bang for your buck. If you're okay with weighing, or measuring out your dose, this will save you a ton of money over the alternatives.
