Niacin Supplements Guide


Niacin is very important for the human body, and a lack of this nutrient can have negative effects on overall health. Large doses of vitamin B3 are used to treat high cholesterol, and they can reduce cardiovascular risk.

Niacin supplements are taken by people who want to lower their cholesterol, but these products can also boost brain function and reduce arthritis pain.

The two main chemical forms of vitamin B3 are niacinamide and nicotinic acid. One of the reasons why niacin is important for the body is because it helps enzymes convert food into energy. It’s also good at repairing DNA and signaling cells.

What Are Niacin Supplements?

Niacin is another name for vitamin B3, and it’s a nutrient that your body needs to stay healthy. Supplements that contain this nutrient offer a variety of benefits, and they’re great for undergoing a niacin flush.

Vitamin B3 can be found in green vegetables, eggs, milk, meat and fish, and nicotinic acid can also be obtained from a supplement. Niacin is used as fuel for the body, and each of the major B vitamins help with the absorption of carbohydrates, which fuel daily activity.

Niacin supplements can also help the body metabolize protein and fats, and they can improve nervous system functioning. One of the main reasons why people use niacin supplements is to lower LDL cholesterol, which is known as the bad cholesterol.

A high-quality niacin supplement can help prevent cardiovascular disease, and it can elevate HDL cholesterol, which is healthy for the body. Research also shows that vitamin B3 can reduce the risk of diabetes, osteoarthritis, cataracts and Alzheimer’s disease.

Since niacin is responsible for assisting with energy production, it’s vital for a healthy nervous system, and the optimal amount of vitamin B3 is different for older individuals.

The amount of niacin contained within a typical supplement is enough to elevate vitamin B3 levels in the body, and if you consume too much of the supplement, you’ll experience flushing and burning.

Benefits of Niacin Supplements

A deficiency in niacin can result in headaches, diarrhea, depression, fatigue and memory loss, and it can even cause irritating skin problems. Most people who live in Western countries don’t have a niacin deficiency, but since some people are deficient in vitamin B3, supplementation can help.

These supplements offer several great benefits, and one of the main reasons why people supplement with vitamin B3 is to lower LDL cholesterol. In fact, the use of niacin for the treatment of high cholesterol started in the 1950s, and it can lower bad cholesterol by up to 20 percent.

However, due to the potential side effects, niacin isn’t used as a primary treatment for high cholesterol. Niacin supplements can also increase HDL cholesterol, which is the good type.

By preventing the breakdown of a protein that makes HDL, they can raise HDL levels by up to 35 percent. Another benefit of taking supplements that contain niacin is lower triglycerides.

A type of fat that floats around in the bloodstream consists of triglycerides, and it’s not good for overall health. Some of the best niacin supplements can lower the amount of these unhealthy fats within the blood stream by up to 50 percent, and they provide this benefit by preventing triglyceride synthesis.

Another reason why people supplement with vitamin B3 is to prevent heart disease, and it’s good at reducing oxidative inflammation and stress. These issues cause the arteries to harden, and by reducing these stressors, niacin can improve cardiovascular health.

Are There Any Side Effects?

When obtained through natural food sources, vitamin B3 doesn’t cause any unwanted side effects, but in the form of a supplement, it comes with the risk of side effects. A few potential effects of consuming niacin as a supplement are liver toxicity, vomiting and nausea.

It’s important to know that some side effects are much more common than others, and the odds of experiencing the worst effects increase as the dosage is raised. A very common effect caused by these supplements is called the niacin flush, and it’s the result of dilated blood vessels.

When this happens, flushing can occur in the neck, chest and face, and it’s almost always accompanied by burning and tingling sensations. Some other common side effects are nausea, stomach irritation and vomiting, and these issues are much more common when taking slow-release vitamin B3 supplements.

One of the dangerous effects of taking too much niacin is liver damage, and this problem is much more likely to occur among people who supplement over a long period of time. In some cases, doses between three to nine grams of niacin per day have caused impaired blood sugar control, and this is another potential side effects of supplementation.

A rare side effect is blurred vision, and since niacin can increase the total amount of uric acid in the body, it has the potential to cause gout. Although the flushing effects can occur at low doses, most unwanted side effects are caused by taking large doses of niacin.

How to Take Niacin Supplements

Niacin is an essential nutrient, and everyone needs it. However, most people don’t get enough vitamin B3 from their daily diet, and by supplementing with niacin, it’s possible to eliminate the negative effects that are caused by a deficiency. It’s quite common for these products to be recommended to people who’re at risk for heart disease and high cholesterol.

The amount of niacin in most supplements is much higher than what would be found in food, and therapeutic doses are measured in grams. Most vitamin B3 supplements come in a bottle, and the active ingredient is delivered with a capsule or tablet.

People who have trouble swallowing should consider capsules because they’re easier to wash down with a glass of water. Before supplementing with niacin, it’s important to know the recommended dosages. Most supplements will say how much to take per day, and a single serving might consist of a single capsule. For the best results, it’s a good idea to follow the specific instructions on the product label, but the general guidelines can also be helpful.

The recommended dietary allowances for adults 14 to 16 milligrams per day, and for pregnant or breastfeeding women, the doses are 17 to 18 milligrams. These are the therapeutic doses recommended for niacin supplementation, but it’s never a bad idea to speak to a physician and ask for a recommendation.

What to Look for In a Good Niacin Supplement

Top supplements that contain niacin deliver the active ingredient in several different ways. Some products deliver the main ingredient slowly, and others deliver is quickly and promote the rapid absorption of vitamin B3. The way that the active ingredient is delivered can have a major impact on the side effects produced by the supplement.

Many well-known supplements use an immediate-release delivery method, which is great for boosting HDL levels in the blood. This form of niacin is quickly absorbed by the body, and it’s also quickly excreted. After consuming immediate-release niacin, it takes between 30 to 60 minutes to reach peak blood levels, and the half-life of the formula is about one hour.

When using immediate-release niacin supplements, it’s best to consume them after meals, and most products will recommend taking several doses per day. Another option is a flush-free supplement, which doesn’t release free niacin into the body.

The major issue with flush-free formulas is that they have extremely poor bioavailability within the body, which renders them almost useless. Time-release niacin supplements are popular products, and they’re regularly used to reduce the risk of heart disease.

After a dose of this product is consumed, the capsule releases the active ingredient slowly, and it can take up to 12 hours for the full dose to be released. Although these products are good at reducing unwanted flushing, they can be hard on the liver.

When shopping for niacin supplements, it’s important to consider the delivery method and find out what the capsules are made from. Some of the best products deliver the active ingredient using vegetarian capsules, and since they don’t contain yeast, sodium, sugar, wheat, gluten or dairy, they’re ideal for people who have food allergies.

Most supplements offer time-release or immediate-release capsules, and the safest option is the immediate-release capsules. The products that quickly release niacin into the bloodstream are better than time-release products at reducing triglycerides and boosting HDL.

In fact, the best products available are wax-matrix niacin, and although they place a small amount of stress on the liver, they offer significantly more therapeutic value than alternative options. Vitamin B3 is one of the best nutrients for reducing bad cholesterol, and it’s available in several different types of supplements.

Before purchasing a specific product, it’s a good idea to avoid flush-free formulas because the bioavailability is extremely low. It’s very important to read the product label and find out if it’s an immediate-release or time-release formula.
