240 Capsules of fast release Niacin Per Bottle
Each bottle contains 240 capsules of high-quality 500mg of Niacin. Please be aware that taking high dosages of this Niacin version of Vitamin B3, 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 common temporary side effect of taking niacin some experience; it’s also a protocol used by some physicians. The “niacin flush” happens when capillaries expand, increasing blood flow to the skin’s surface. Studies have shown that niacin flush has a variety of benefits but is often uncomfortable for some people. Talk with your physician if this product is right for you. However, if you are looking for vitamin b3 without the flush, we’d recommend using a different form of Vitamin b3 such as Niacinamide that does not cause this “flush.” Nutricost also offers a smaller 100mg dosage version.
