Criteria for Evaluation

There are so many supplements’ manufacturers and distributors globally that you are most probably confused on what is best for you. Shopping for supplements at times can be so confusing because you don’t know what to look out for. And when you get one, you wonder whether it will meet your needs. We have vigorously researched the best niacin supplements, on your behalf. We have dug through the literature, tests, ratings, and reviews to come up with a list of the best niacin products in the market.

This is the criteria that we used to come up with the list of products.

Product testing

With improved marketing strategies that manufacturers and distributors have adopted of late, it is challenging to tell whether the benefits of products they claim are true or it’s just marketing gimmicks.

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 chose supplements that have the best objective reviews, ratings, and unbiased responses. We also picked out problems that the users had while taking the supplements. You will, therefore, know what to expect with each product. For instance, most users complained of niacin flush. The flush is not harmful and can be minimized by taking the supplements with a meal. You will, therefore, know at a glance, the advantages and disadvantages of each product.

Although most supplements have individualized response, if a product worked for a large percentage of the population sampled, then the highest chances are that it will work for you too.

Manufacturer’s reputation

The list of our products is from manufacturers with an excellent reputation for high-quality products. These manufacturers have been approved to produce these supplements and also, have other products that have previously been tested and proved to match their client’s needs.

Safety of the supplements

All the niacin supplements that we have listed on this list are safe for you not except if you are hypersensitive to any of the ingredients. 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.

Ingredients

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.

Other binding ingredients include Hypromellose, Silicon dioxide, Magnesium Stearate, Calcium, Gelatin capsules etc.

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.
