Vitamin B3 & Niacin Supplements

Vitamin B3 is a water-soluble B vitamin commonly known as niacin. It plays several important roles in the body, including helping your body release energy from the food you eat.

Vitamin B3 also supports normal nervous system and psychological function, helps maintain normal skin and mucous membranes, and contributes to the reduction of tiredness and fatigue.

At Evergreen, you'll find vitamin B3 and niacin supplements from trusted brands in a range of strengths and forms.

What Is Vitamin B3?

Vitamin B3 is the collective name used for different forms of niacin, including nicotinic acid and nicotinamide, which is also known as niacinamide. Although you'll see these different names on supplement labels, they're all forms of vitamin B3.

What Does Vitamin B3 Do?

Vitamin B3 contributes to:

• normal energy metabolism
• normal functioning of the nervous system
• normal psychological function
• the maintenance of normal skin
• the maintenance of normal mucous membranes
• the reduction of tiredness and fatigue

Like the other B vitamins, vitamin B3 is water soluble and needs to be obtained regularly through your diet.

What Foods Contain Vitamin B3?

Niacin occurs naturally in a variety of foods, including meat, fish, eggs and wholegrains. Your body can also make some niacin from the amino acid tryptophan, which is found in protein-containing foods. For most people, a varied and balanced diet should provide the vitamin B3 they need.

Niacin, Nicotinamide or Niacinamide: What's the Difference?

The terminology around vitamin B3 can be confusing. Niacin is commonly used as an umbrella term for vitamin B3, while nicotinic acid and nicotinamide are different forms of the vitamin.

Nicotinamide is also known as niacinamide, so products labelled nicotinamide and niacinamide are referring to the same form.

When choosing a vitamin B3 supplement, check the product label to see which form is included rather than assuming all B3 supplements are identical.

What Is a Niacin Flush?

Nicotinic acid can cause temporary flushing in some people, particularly when taken in larger amounts. This can feel like warmth, tingling or reddening of the skin.

You'll therefore sometimes see supplements described as “no-flush niacin” or using forms of vitamin B3 that don't generally produce the same flushing effect. A niacin flush isn't something you need to experience to receive vitamin B3 from a supplement.

Always follow the recommended intake on the individual product, particularly with higher-strength niacin supplements.

Choosing a Vitamin B3 Supplement

When comparing vitamin B3 supplements, consider:

• Form – check whether the product contains nicotinic acid, nicotinamide/niacinamide or another form.
• Strength – amounts can vary considerably between products.
• Format – tablets and capsules are the most common options.
• Other nutrients – some products combine B3 with other B vitamins.

Rather than looking for one universal “best vitamin B3 supplement”, choose a formula and strength appropriate for your individual needs.

Vitamin B3 or B Complex?

If you're specifically looking for niacin, an individual vitamin B3 supplement allows you to choose the form and amount you want.

If you'd prefer several B vitamins together, a Vitamin B Complex combines B3 with a selection of other B vitamins in one formula.
