Description

Niacin (vitamin B3) is one of the most under-talked-about vitamins in everyday wellness. Our Niacin B3 Complex pairs nicotinic acid (the flush-producing form) with thiamine and alpha-lipoic acid in one daily capsule.

For energy metabolism, mental clarity, and recovery from tiredness.

What you get

  • 50mg nicotinic acid, the flush-producing form of vitamin B3
  • Thiamine (vitamin B1) for energy metabolism and nervous system function
  • Alpha-lipoic acid, a naturally occurring compound studied for its role in cellular processes
  • 120 vegan capsules, 1 capsule per day, 4-month supply

What the GB Authorised Health Claims say

  • Niacin contributes to normal energy-yielding metabolism.
  • Niacin contributes to the reduction of tiredness and fatigue.
  • Niacin contributes to normal psychological function.
  • Niacin contributes to the normal function of the nervous system.
  • Niacin contributes to the maintenance of normal skin and mucous membranes.
  • Thiamine contributes to normal energy-yielding metabolism, the normal function of the heart, and normal psychological function.

About the niacin flush

At 50mg, nicotinic acid commonly causes a temporary skin flush (warmth, redness, tingling) within 15-30 minutes of taking it. This is a normal, harmless histamine response and usually subsides within an hour. Starting with the capsule alongside food can help reduce its intensity.

What’s NOT in it

  • No artificial colours, flavours, or sweeteners
  • No GMOs, gluten, dairy, soy, or animal products
  • Vegan capsule shell

Also good to know: both Fertility Advance and Fertility Focus contain B-vitamins as part of the preconception package. This standalone complex is for everyday energy support outside the preconception window.

THE SCIENCE

Why it works

A 3-ingredient complex pairing nicotinic acid (vitamin B3 in its flush-producing form) with vitamin B1 thiamine and alpha-lipoic acid.

Niacin and B1 both contribute to normal energy metabolism, normal nervous system function, normal psychological function, and the reduction of tiredness and fatigue. B1 specifically contributes to normal heart function (GB Authorised Health Claims).

About the niacin flush

Nicotinic acid produces a temporary warm, tingling sensation in the skin lasting 15 to 30 minutes. Histamine-mediated. Harmless. Take with food, start at half a capsule for the first few days. Avoid taking with grapefruit.

USAGE

How to take it

1 capsule per day, taken with food to reduce the intensity of any flush. Start with half a capsule for the first 3 to 5 days. Avoid taking with grapefruit.

If you take medication for blood pressure, cholesterol, or diabetes, speak to your GP before starting high-dose niacin.

QUESTIONS

Frequently asked

What is the niacin flush?

A harmless warm, tingling, sometimes red feeling in the skin lasting 15 to 30 minutes. Histamine-mediated. Not an allergy.

Why include B1 and ALA?

B1 brings extra GB Authorised claims including normal heart function and energy metabolism. ALA is a naturally occurring compound found in every cell of the body and in foods like spinach.

Why avoid grapefruit?

Grapefruit can interact with niacin metabolism, potentially intensifying side effects.

Can I take it during pregnancy?

Speak to your midwife. High-dose nicotinic acid is usually not recommended during pregnancy.
