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.

Good supplements, inexpensive, and easier to swollow!

Really like the products by bulk supplements. The powdered supplements are so much easier to take.

Powder dissolves completely

Have been high dosing on niacin in capsules form for last 6 months. As they are way too many pills to swallow so even though I bought in capsules, I usually open up the capsule and mix it in water. Have tried all brands and none dissolve well. They always left behind huge sediment at the bottom of the glass. Finally decided to go for Bulk Supplement powder and this powder totally dissolves in water, leaving no sediment.
