What does Vitamin B3 Do?

It Prevents Heart Disease

It reduces oxidative stress and inflammation, both of which are involved in atherosclerosis, the hardening of the arteries.

It Treats Type 1 Diabetes

Type 1 diabetes is an autoimmune disease which involves the body attacking and destroying cells that create insulin in the pancreas. Niacin protects those insulin-creating cells.

It Reduces Arthritis Symptoms

Niacin eases some symptoms of osteoarthritis — it improves joint mobility and reduces the need for NSAIDs.

It Treats Pellagra

People with low niacin intake suffer a deficiency called pellagra. Niacin supplements are reliable in treating pellagra.

It Protects Brain Function

The brain needs niacin to form part of the necessary coenzymes in order to get some energy to function properly. To buttress this, brain fog and some psychiatric symptoms have been associated with niacin deficiency. What else? Some types of schizophrenia brain cell damage have been linked to vitamin B3 deficiency. It also keeps the brain healthy in cases of Alzheimer’s disease.

It Lowers LDL Cholesterol

For over half a century, vitamin B3 has been used to treat high cholesterol issues. It actually lowers LDL, the not-so-good cholesterol.

It Increases HDL Cholesterol

Asides lowering LDL cholesterol, niacin raises the relatively good cholesterol — HDL — by 15-35%. This is possible because it hinders the breakdown of apolipoprotein A1, a protein that helps make HDL.

It Improves the Skin

Vitamin B3 protects the skin cells from sun damage, whether applied to the skin in lotions or taken orally. That’s not all, as it prevents some types of skin cancer too.

Is an Overdose of Niacin Possible?

It’s only possible to overdose on niacin supplements or niacin-based medication, but not a niacin-rich diet, definitely. Niacin is often included in daily multivitamins. It is also an ingredient in prescription medications used to treat high cholesterol and triglycerides.

When taken in prescribed amounts, niacin isn’t harmful. But if taken unnecessarily, an overdose is certain and has its risks.

What’s the Prescribed Dosage?

A number of prescriptions for niacin begin at 100 milligrams (mg). This is usually split between three doses taken throughout the day.

The dose may be sometimes increased to 1,000-2000 mg, as required, but definitely not beyond 2000mg.

Symptoms of Niacin Overdose

A niacin overdose can cause mild to severe symptoms, depending on how much the overdose is, body chemistry, drug interactions, and some other factors.

Mild Symptoms

  • severe facial flush
  • severe itching
  • nausea
  • vomiting
  • diarrhea
  • severe stomach pain
  • dizziness

Severe Symptoms

  • breathing difficulty
  • peptic ulcers
  • gout
  • rapid heartbeat (tachycardia)
  • severe hypotension
