When you eat a healthy diet, your body receives the necessary nutrients to efficiently process the carbohydrates and fats and convert them into glucose energy. Certain substances in food help you utilize calcium and other vitamins and minerals. Many of these substances are not produced naturally in your body, so their supplies must be continually replenished. If you have nutritional deficiencies, you may not only lack energy but suffer from cardiovascular problems.
Niacin is an essential B-complex vitamin that may help your body convert carbohydrates into energy, while supporting good circulation and cardiovascular health. It also affects the adrenal glands, prostaglandins (hormones related to muscle contractions), and the production of sex hormones.
Some studies suggest that niacin (also known as vitamin B3) may be helpful in promoting healthy vision, while alleviating skin conditions as well as joint pain and discomfort. It has an antioxidant effect and may reduce the risk of developing conditions that lead to cognitive decline. Niacin also works to reduce anxiety, promote natural relaxation, and help you sleep better. Symptoms of mild niacin deficiency include fatigue, indigestion, canker sores, and sadness; it may be due to excessive alcohol intake. Niacin deficiencies can be treated through diet and supplements.
When taken as a supplement, niacin may cause temporary flushing, redness, warmth, or itching, but these effects usually subside when your body becomes accustomed to continuous use. Progressive Labs’ Niacin Sustained Release is a high-potency formula that contains 500 mg of niacin in the form of nicotinic acid. It’s formulated to release part of the niacin quickly and the remainder more slowly over several hours to minimize uncomfortable flushing.
This bottle of Niacin Sustained Release 500 mg Tablets should last you from one to three months, depending on your dosage.

I love Niacin Sustained Release. It brought down my slightly elevated cholesterol into normal range in only a couple of months.

Great product! Been using Niacin Sustained Release for several years on recommendation of my doctor.
Seems to get stuck in my throat every once in a while but really not much of an issue. Edges are fairly squared off which I think attributes to this. If they could re-shape the pill to round the edges it would help.
