Best Niacin

Niacin is known to have a “hot flush” associated with it. (See Reference 1) If you’re looking for a flush-free niacin supplement instead:

Vitamin B3, also known as niacin, is an essential nutrient with antioxidant and anti-inflammatory properties that was first discovered in 1873. It is made up of nicotinamide and nicotinic acid and is needed for cellular functions in the body, including enzyme function and DNA synthesis.

We get B3 in our diet, mainly from muscle meat, organ meat, fish, legumes, and nuts. It’s also available in convenient supplements for those who need an additional boost. (See Reference 2)

Vitamin B3 Deficiency

Severe vitamin B3 deficiency, known as pellagra, isn’t common in developed countries due to improved nutrition and fortified foods. However, low levels can occur and may cause:

  • Poor memory and confusion
  • Fatigue
  • Bright red, swollen tongue
  • Low mood
  • Poor circulation
  • Skin problems and roughness

Health Benefits of Vitamin B3

Interestingly, research has shown that even when a B3 deficiency isn’t present, supplementing with this nutrient can still have significant health benefits, such as the following.

Energy

We need vitamin B3 for energy production. It’s a crucial nutrient involved in two coenzymes called nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). They are essential for producing energy molecules called adenosine triphosphate (ATP) from the food we consume. So, if there isn’t enough B3 floating around our body, we can’t efficiently produce energy and may feel tired and sluggish.

Anti-Inflammatory

Vitamin B3 has anti-inflammatory benefits due to one of its metabolites called 1-methyl nicotinamide. (See Reference 4)

A 2015 clinical study found that taking 500mg of slow-release B3 daily for one month was enough to lower a marker for inflammation called high-sensitivity C-reactive protein (hs-CRP). (See Reference 5)

Heart Health

Vitamin B3 has been studied extensively for its heart health benefits.

Research has confirmed that B3 at therapeutic doses can improve heart health by:

  • Lowering “bad” LDL cholesterol levels in the blood (See Reference 3)
  • Lowering levels of lipoprotein(a) (See Reference 7)
  • Reducing blood triglyceride levels
  • Increasing levels of the “good” HDL cholesterol in the body (See Reference 6)
  • Preventing atherosclerosis — hardening of the arteries
  • Acting as a vasodilator and improving blood circulation
  • Lowering inflammation
  • Fighting free radical damage

Vitamin B3 is often recommended by doctors at high doses to lower cholesterol levels in those who can’t or don’t want to take statin medication.

Skin Health

Vitamin B3 is a great skin nutrient that reduces inflammation and promotes healing.

It may be especially useful for acne, (See Reference 8) an unpleasant skin condition that causes embarrassment to sufferers. In 2017, a review study found evidence that taking oral nicotinamide — a form of vitamin B3 — causes a significant reduction in the appearance of acne.

Healthy Joints

As we get older, stiffness and joint pain can slow us down. Research suggests that taking B3 is a simple and useful way to improve the health and function of joints, perhaps due to its anti-inflammatory properties. (See Reference 9)

A 1996 placebo-controlled study found that niacinamide supplementation reduced joint inflammation, increased joint mobility and allowed a reduction in anti-inflammatory medication. This is encouraging, but it’s worth noting that updated research is needed.

Brain Health

Research indicates that optimizing vitamin B3 levels can support healthy brain function as we age and protect against a decline in cognitive functioning. (See Reference 10)

Vitamin B3 Considerations

Vitamin B3 is a water-soluble vitamin, so the body doesn’t store it and excess amounts are easily excreted. Toxicity and overdose are unlikely but always speak to your healthcare provider before taking high doses of B3.

A common side effect of supplemental vitamin B3 is “niacin flushing”. It’s a harmless reaction that results in flushing, itching, and tingling in the face, chest and neck due to blood vessel dilation. It doesn’t last long, but taking a slow-release vitamin B3 can limit this effect for those that want to avoid it.
