Niacinamide Vitamin B3 Capsules give you a high dose of vitamin B3 without the flushing that niacin causes. Each capsule provides 500mg of niacinamide and you take one a day with food. One pot holds 90 capsules, which is a 90 day supply.
Niacinamide is one of the two main forms of vitamin B3. Your cells turn it into NAD+, the coenzyme they use to release energy from food and repair DNA.
Niacinamide Vitamin B3 Capsules are most useful for:
Each capsule provides 500mg of niacinamide, which is 3125% of the daily reference value for vitamin B3. There are no fillers or binders, only niacinamide and the vegetable capsule shell. Nicotinamide, niacin amide and vitamin B3 are other names for niacinamide.
Take one capsule a day with food. Some practitioners advise up to three capsules spread across the day for skin or joint comfort, so only take more than one on their advice.
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
What is the difference between niacinamide and niacin?
Both are forms of vitamin B3. Niacin, also called nicotinic acid, can make your skin flush, while niacinamide gives you the same vitamin without that reaction. Niacin is the form to choose if you want B3 for cholesterol, because niacinamide has no effect on cholesterol or triglycerides.
How much niacinamide should I take a day?
Take one capsule a day, which gives you 500mg. Most people tolerate up to 1000mg a day well, but leave any increase above one capsule to your practitioner.
When is the best time to take niacinamide?
You can take it at any time of day, with a meal.
Can I take it with other supplements?
Yes. Niacinamide is often taken alongside the other B vitamins, which work together to release energy from food.
Will niacinamide make me flush?
No. Flushing is a reaction to niacin only, so niacinamide gives you the vitamin without it.
Is niacinamide the right form for NAD+ support?
Yes. Every cell makes NAD+ from niacinamide, so for general NAD+ support and healthy ageing one capsule a day is enough.

Both are forms of vitamin B3. Niacinamide (nicotinamide) does not cause the flushing and tingling that niacin (nicotinic acid) can, making it the preferred high-dose form for most people.
500mg per capsule, one daily. 90 capsules per pot.
Niacinamide is a precursor to NAD+, a coenzyme present in every cell and involved in energy metabolism and DNA repair, and is widely researched for skin health.
No. The flushing reaction is specific to nicotinic acid. Niacinamide provides high-dose vitamin B3 without flushing.
Each capsule is 500mg of niacinamide, the form of vitamin B3 that does not cause flushing. At one capsule a day a pot of 90 lasts three months.
Yes, it is vegan. It is free from gluten, dairy and nuts. The full ingredient list and allergen information are on the label image and in the Information and Allergens tab above.
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
