Nutricost Niacin delivers a potent 100mg dose of Vitamin B3 per capsule in a generous 240-count bottle. Designed for adults seeking the energizing benefits of niacin, this supplement is non-GMO, gluten-free, and rigorously third-party tested. Manufactured in a GMP-compliant, FDA-registered facility, it guarantees premium quality. Expect the signature niacin flush—a sign of its active potency—making it a top choice for those who want authentic Vitamin B3 effects with excellent value.

## Description

Each bottle contains 240 capsules, each containing 100mg of Niacin. Nutricost strives to provide the best supplements at the best prices. Please be aware that taking high dosages of Vitamin B3 (Niacin), especially when your body is not used to it, can lead to what is often referred to as the Niacin flush. A "niacin flush" is a temporary side effect of taking niacin; it's also a protocol used by some physicians. Studies have shown that niacin flush has a lot of benefits. However, if you are looking for just the benefits of vitamin b3 without the flush, we'd recommend using a different form of Vitamin b3 such as Niacinamide or Niacin from Inositol Hexanicotinate.

Review: Worthy - Good
Review: Been using this since 2024 and this is my verdict on this Brand. Easy to swallow with no taste. Side effects are expected, the flush. Dosage of 100mg is a good start but I prefer 200mg is sufficient (I've gone all the way up to 500mg). Great value for the money, especially when compared to pharmaceutical prices.
