Description
Doctor’s Best Sustained-Release Niacin 500mg – High-Strength Vitamin B3
Doctor’s Best Sustained Release Niacin provides 500mg of vitamin B3 as niacin (nicotinic acid) in each tablet. Rather than releasing everything at once, the tablet is designed to release niacin slowly over several hours, which many people find makes the familiar warm skin flush of niacin less intense. It is a high-strength, specialist B3 product from a brand known for straightforward, science-based formulas.

Who Is It For?
This is a specialist product for adults who have a clear reason to take high-strength niacin, ideally after speaking with a GP or pharmacist. It is not intended for casual daily top-ups; a standard B-complex is usually a better choice for general wellbeing.

Doctor’s Best has spent decades producing science-based supplements in the United States, with a range covering single vitamins, minerals and specialist nutrients.
FAQs
Is 500mg of niacin a high dose?
Yes. It is many times the daily reference intake for niacin, so it is not suitable for everyone. Speak to your GP or pharmacist before use, particularly if you take other medication or have any liver concerns.
Will I still get a niacin flush?
Some people still notice mild warmth or redness. The sustained-release tablet is designed to make it less pronounced, but responses vary.

Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily intake. Keep out of reach of young children. Formulations and packaging can change – always read the label on the product you receive before use.
Take the serving shown on the label with food, swallowing the tablet whole with water – do not crush, break or chew sustained-release tablets. Avoid taking it with hot drinks or alcohol, which can make flushing more noticeable.
