Health Benefits Of Niacin (Vitamin B3)

When it comes to our wellbeing, we often look for quick fixes and external solutions.

But, what if the key to our health lies within the foods we eat?

Enter niacin, also known as vitamin B3.

It’s a remarkable nutrient that can have profound impact on our overall wellbeing.

From supporting heart health and brain function to keeping your skin healthy, niacin offers a range of benefits.

I’m Dr. JJ, a naturopathic doctor in Toronto, and if you’ve got questions about nutrition, I’ve got answers for you.

This is part of an ongoing series on all the essential nutrients we need in our diet.

When it comes to the B complex in particular, we’ve looked at thiamine (vitamin B1), vitamin B6, and biotin (vitamin B7).

Today, it’s niacin’s turn.

What Is Niacin?

Niacin, also known as vitamin B3, is a water soluble vitamin that plays a vital role in the proper functioning of your body.

When you eat a water soluble vitamin, your body uses what it needs and flushes the rest out with your urine.

All the B complex vitamins are water soluble, and so is vitamin C

Compare this with fat soluble vitamins like vitamin A, vitamin D, and vitamin E, which your body stores in your fat tissues for later use.

Niacin is essential for energy metabolism, helping convert the food that we eat into energy.

Niacin also plays an important part in DNA repair, producing hormones, and keeping your skin, digestion, and nervous system in good shape.

It also has benefits in managing diabetes, heart disease, and more.

With its wide range of functions, niacin is an integral part of maintaining your overall health.

What Does Niacin Do For The Body?

Curious about the wonders of niacin and what it can do?

Let’s take a look.

1. It Helps Manage Your Cholesterol Level

Niacin can be a game changer when it comes to managing your cholesterol levels.

It works in two ways.

First, it lowers the “bad” cholesterol (LDL).

Second, it raises the “good” cholesterol (HDL).

By reducing LDL cholesterol, niacin helps prevent buildup of plaque in your arteries, which can lead to heart disease.

On the other hand, increasing HDL cholesterol helps remove LDL cholesterol from your arteries, which further protects your heart.

2. It Helps Manage Your Blood Pressure

Keeping your blood pressure in a healthy range is crucial for a strong cardiovascular system.

Niacin can be a helpful tool in managing blood pressure levels in a few ways.

First of all, it reduces your cholesterol – we talked about that above already.

It also widens your blood vessels, allowing blood to flow more easily and reducing pressure.

It has a mild diuretic effect, which means it helps get rid of extra fluid in the body.

This can also reduce the pressure on your blood vessels.

3. It’s Good For Your Brain

Your brain makes use of a lot of different nutrients.

It uses zinc and vitamin E to form and preserve memories, vitamin K for higher level cognitive functions, and protein to synthesize neurotransmitters.

Adding to the list is niacin.

Your brain uses niacin to access the energy it needs to do its job.

This is one of the reasons why brain fog is a symptom of niacin deficiency – but more on that later.

Niacin is also an antioxidant, which protects your cells from damage.

This has wide reaching benefits, including to your brain.

4. It Keeps Your Skin Healthy

Niacin plays a vital role in keeping your skin in good shape, addressing various skin concerns and giving you a glowing complexion.

One way niacin helps is by strengthening your skin’s protective barrier.

This barrier keeps your skin hydrated and shields it from harmful things in the environment.

Niacin improves the production of special fats called ceramides, which helps maintain moisture in your skin and keep it soft and smooth.

Niacin also helps reduce inflammation and redness, which is good news for people with sensitive or acne prone skin.

Promoting the production of collagen is also something that niacin does.

Collagen is a protein that makes your skin firm and elastic, and is important for keeping your skin young looking.

Using niacin regularly can make your skin smoother, reduce the appearance of wrinkles, and give you a more youthful look.

5. It May Help Manage Type 1 Diabetes

Niacin has been found to improve glucose tolerance and insulin sensitivity, two key factors in managing blood sugar levels.

By improving the body’s response to insulin, niacin may help those with type 1 diabetes to regulate their blood sugar levels.

Niacin has also been shown to reduce markers of inflammation and oxidative stress, both of which can contribute to the development of diabetes complications.

By reducing both, niacin may help ease the long term complications associated with type 1 diabetes, such as heart disease and nerve damage.

However, it’s important to note that niacin should not replace insulin therapy or other prescribed treatments for type 1 diabetes.

Niacin should be used as a complementary approach alongside medical management.

What Are The Signs Of A Niacin Deficiency?

When your body lacks an adequate amount of niacin, it can lead to a deficiency.

Niacin deficiency is called pellagra, and it’s characterized by three particular symptoms that just happen to start with D:

• Dermatitis (skin rashes and inflammation)
• Diarrhea
• Dementia (mental confusion, memory loss, and cognitive impairment)

These symptoms can vary in severity and may appear gradually or suddenly.

Digestive issues are another indicator of a niacin deficiency.

This can lead to weight loss and malnutrition if the deficiency persists.

Niacin deficiency is relatively rare in developed countries, as it’s commonly found in a variety of foods.

However, certain conditions such as drug misuse, long term medication use, or certain diets may increase the risk of niacin deficiency.

Over a long enough period, pellagra is fatal.

Foods High In Niacin

One of the best sources of niacin is poultry, such as chicken and turkey.

These lean meats not only provide high quality protein, but also contain significant amounts of niacin.

Fish, especially salmon and tuna, is another excellent source of niacin.

Besides being rich in omega 3 fatty acids, which are good for heart health, these fatty fish provide a good amount of niacin.

For those following a vegetarian or vegan diet, legumes like lentils, chickpeas, and beans are fantastic niacin rich options.

Whole grains, such as wheat, barley, and oats are also an excellent source.

Additionally, nuts and seeds are great sources of niacin and can be added to salads and smoothies.

It’s worth remembering that while niacin can be obtained from food sources, some people may require niacin supplements.

Can Too Much Niacin Hurt You?

While niacin offers numerous health benefits, consuming too much can lead to niacin toxicity.

One of the most common symptoms of niacin overdose is a flushing reaction.

This can cause the blood vessels to dilate, leading to a warm, tingling sensation, and redness and itching of the skin.

Although it’s uncomfortable, this reaction is usually harmless and temporary.

However, in more severe cases, individuals may experience gastrointestinal symptoms.

This can include nausea, vomiting, diarrhea, and abdominal pain.

In rare instances, high doses of niacin can lead to liver toxicity and decreased blood pressure.

However, it’s very difficult to overdose on niacin through diet alone.

Niacin flush tends to only happen if you’re supplementing at high doses.
