Niacin and nicotinamide make up Vitamin B3 complex. Some vitamin B3 supplements contain nicotinic acid while others contain nicotinamide/inositol Hexa nicotinate.
Niacin is primarily used to lower blood cholesterol alongside other lipids lowering drugs such as Crestor, Lescor, and lpitor. Scientific studies have shown that niacin can lowers “bad cholesterol” (LDL and triglycerides) and raises “good cholesterol” (HDL).
It also reduces the risk of artherosclerosis by lowering Low-Density Lipoproteins. Excess cholesterol is usually deposited in the lumen of blood vessels resulting in hardening and narrowing of arteries, which is referred to as atherosclerosis. It may cause a heart attack or even stroke. Due to this effect, niacin may reduce the risk of a subsequent heart attack in people who have already had one.
It is important to note that supplements with nicotinamide/inositol Hexa nicotinate, do not have a cholesterol lowering effect and does not cause flushing like products with nicotinic acid.
Niacin is also an FDA approved drug for treatment of pellagra. Pellagra is a disease that is as a result of inadequate intake of niacin, long term use of chemotherapy drugs and poor absorption of nutrients. Pellagra has four main symptoms commonly referred to as the 4Ds. They include Dermatitis, Dementia, Diarrhoea, and eventually if not treated, results in Death. The World Health Organisation recommends the use of nicotinamide/inositol Hexa nicotinate for treatment of pellagra opposed to nicotinic acid.
Niacin is a precursor of Nicotinamide Adenine Dinucleotide (NAD) and Nicotinamide Adenine Dinucleotide Phosphate (NADP) which are crucial in metabolism. NAD plays a crucial role in DNA repair, metabolism of carbohydrates, proteins, and alcohol while NADP helps in synthesis of fats and cholesterol. The supplements, therefore, boost metabolism and energy level in your body.
Therapeutic dosages to lower lipids are usually significantly raised as compared to the daily recommended intake. Most doctors recommend that you start with 100mg three times daily as you slowly increase the dose. For the extended release formulation, the dosage is usually 500mg once daily. It is important to note that niacin supplements have an individualized response. Therefore, your doctor should give you dosage directions depending on your condition.
For extended release supplements, you should swallow them whole not unless the tablet has a broken line. It is not advisable to crush or chew as the drug will be quickly absorbed yet, the dose it is usually higher as compared to non-extended release. Crashing will mean that the drug will be quickly absorbed and therefore give you immediate side effects such as niacin flashing.
Take the supplements with a low-fat meal or a cold beverage, to lower the flushing side effect.
Niacin supplements should be stored at a well-controlled room temperature between 200C- 250C (68oF- 770F). The supplements should also be stored away from children.
You should take niacin with caution if you have certain conditions or taking certain drugs
You should inform your doctor if you have:
- Active liver disease
- Kidney disease
- Active peptic ulcers disease
- Active arterial bleeding
- Myasthenia Gravis
You should also be careful and report to your doctor if you are taking medication such as:
- Blood thinners – warfarin, heparin, clexane
- Antihypertensive – nifedipine, amlodipine, nicardipine
- Cardiac medication – nitroglycerine
Or any other prescription drug, over the counter drug or herbal medication that you are taking.
Avoid alcohol while taking niacin supplements. Alcohol can raise the risk of liver damage and worsen the side effects of niacin supplements.
Call for medical help in case of any over dose. Signs of overdose include excessive nausea, diarrhea, vomiting, and excessive flushing. Over dosage of niacin can potentiate liver toxicity.
Use of Niacin supplements in pregnancy and breastfeeding
If you are expectant, planning to get pregnant or suspect that you are expectant, please notify your doctor. Animal studies have shown that niacin supplements can cause birth defects. However, the supplements may be used if the benefits of the supplements outweigh the risks posed to the baby. This is a very critical decision that should be made together with your doctor.
Niacin also crosses to breast milk and can potentially harm a nursing baby.

We have therefore done a market research and brought you niacin supplements that have been tried and tested. The general population has used most of these products. Therefore, we have saved you the hustle of trying to figure out what works and what does not, what is safe and what is not. We have established that our list of products have the benefits that the manufacturers and distributors claim to have.
User reviews and ratings

We have broken down all the ingredients (both the main ingredients, binding agents, and additives) found in each product for you to quickly pick out if you are sensitive to any.
Possible side effects
The most common adverse effect of niacin supplements is the niacin flush. A niacin flush mainly occurs on the face and is, therefore, most commonly referred to as facial flush. It can last for about 15 to 30 minutes and sometimes, up to two hours. The flush may be accompanied by itching, redness, and tingling sensations.
To minimize the effect of flushing, do not take the supplement on an empty stomach. Take the supplements with a low-fat meal, snack, or a lot of water. It can be worsened by taking the supplements with hot beverages, spicy food or alcohol. Flushing can also be eliminated by taking aspirin or ibuprofen though long term use may be detrimental to your health.
Supplements that have extended release have shown to cause less or no flushing though they may cause liver damage. Supplements containing inositol hexanicotinate are flush free although there is the controversy that this type of niacin supplement is not very efficient in lowering cholesterol.
We have selected both extended release and non-extended release niacin supplement products. Some people may not tolerate the flushing effect while others prefer to feel the flush to be assured that the drug is working.
Other possible side effects include a headache, nausea, vomiting, rashes, and diarrhea.
The main ingredient in niacin supplements is either nicotinic acid or inositol hexanicotinate. The difference is that nicotinic acid can lower lipid level yet inositol hexanicotinate cannot. Therefore, nicotinic acid is recommended for lowering cholesterol while but inositol hexanicotinate is generally for meeting dietary requirements of niacin. Also, nicotinic acid based supplements have a flushing effect while inositol hexanicotinate based products do not. It is vital for you to know why you are taking the supplements for you to get the right ingredient. Usually, your doctor will advise on what will work for you best. We have reviewed products that have nicotinic acid as well as inositol hexanicotinate.
Niacin supplements can be extracted from animal or plant products. We have picked products that are derived from vegetables hence fit vegetarians and nonvegetarians.
Some of the products that we have selected are sugar-free and hence fit for people with diabetes. If are diabetic and would like to use niacin supplements, it is wise that you seek your doctor’s opinion first. Niacin increases the resistance of insulin hence may cause a spike in blood sugar.
