Type, Size & Quantity

Each of them plays an important role in the metabolism of energy in that they may be converted into coenzymes that the enzymes in each cell can make use of when completing the actions that create energy for the body. These coenzymes have been named NAD and NADH respectively. Taken in amounts of about 100mg or less, both Niacin and Niacinamide ostensibly perform the same actions. When taken at levels greater than 100mg though, this is where their overall effects begin to differ. Niacin is able to help the body balance the levels of good and bad cholesterol present in the blood, while Niacinamide is essential in monitoring insulin levels, blood sugar content, and health of joints. Niacinamide may also be used along with other supplements and minerals to increase the overall effectiveness and health of the nervous system, the digestive system and the circulatory system.

Of all of the B vitamins, Niacin is considered to be one of the most stable. It is water soluble and it is vital in sustaining life. It resists the effects of those elements which may cause erosion such as wind, heat, light, alkali, and acids. Both Niacinamide and Niacin are soluble in alcohol and water, and are quite rapidly absorbed into the digestive system once consumed. The body often won't to store extra amounts of these vitamins within the liver; however the majority of it is usually expelled during urination.

One of the most important roles of Niacinamide is in its ability to help clear the body of toxins. Hence the term "Niacin flush" which it is sometimes associated with and the reason that Niacinamide is often found in such high stores in the liver, the detoxification center of the body. It is also necessary in stimulating the adrenal gland at certain points in order to increase hormone production and synthesize certain sex based hormones. It can speed up general chemical reactions controlled by enzymes at a cellular level. These reactions include, but are not limited to processes which strengthen cell integrity and also produce energy for the body to use; meaning that without Niacin or Niacinamide, the body would operate much more slowly, would be much weaker, and would also not be able to build many energy reserves. Through this indirect influence it helps the production of DNA, in the breakdown and metabolizing of fats, and in the general maturation of each individual cell.

Pellagra, a disease that occurs as a result of Niacin deficiency, may be treated by Niacinamide. Perhaps one of the greatest benefits of Niacinamide use is the fact that it can be used to synthesize HCL, an acid which is essential in the digestive process.

Health Benefits Provided by Niacinamide

Niacinamide is indirectly involved in the production of cellular energy. It also keeps blood flow going smoothly and controls hormones as well as Glucose levels and HCL in the body; which helps to further positively affect energy production, nervous system operation, and digestion. Niacinamide affects the flexibility and health of the skin and improves the effectiveness of the circulatory system by widening the blood vessels, thereby distributing blood more rapidly to the parts of the body that need it and getting rid of harmful toxins in the blood much more quickly.

So happy I found Niacinamide Powder

Hi, I love the products with this company! I make 10% Niacinamide cream for pre-cancer lesions (reocmmended by a doctor for a family member). This is a product we must watch though the high ph of this product. Niacinamide is also great for healthy skin and it can reduce the aging process. All the general face creams I make, have a 3 to 5% niacinamide in them to enhance the benefit to the skin. Thank you so much Bulk Supplements!! I am a loyal customer!

The real deal

Wow...intense flush, not like other niacin products I have tried, this is clearly the purest form of nicotinic acid. The flush is fast, the mental effects are long lasting, and as usual the value can't be beat. If you are looking for pure nicotinic acid I highly recommend this product. Thanks again



great product , it helps my energy greatly
