Niacin is one of the B complex Vitamins required by the body to ensure that the skin and digestive system remain healthy. The recommended daily intake is determined by the total number of calories that are taken.

There are three forms of niacin supplements available including niacinamide, nicotinic acid and inositol hexanicinate. Each form of niacin has its own specific healing effects on the body. These supplements are used to increase good cholesterol while lowering the bad cholesterol in the blood.

The niacin supplements can only have an effect on the cholesterol if you take more than the recommended daily requirement. This means you will have to take more than 1000 to 2000 mg.

Some of the conditions that can be treated using the niacin supplements include inflammation of joints, circulatory problems, and calf pain, ringing in the ears, tinnitus, depression, panic disorders, and anxiety and can even control blood sugar levels in the body.
