Niacin Capsules by Seeking Health provide 50 mg of niacin, also known as vitamin B3, a nutrient that is naturally produced in the body and is found in many of the foods we eat. Niacin may help support healthy circulation, healthy carbohydrate and fat metabolism, and healthy skin. Because the body cannot store niacin, it requires adequate intake of this important vitamin everyday.*

Niacin may support normal mood regulation by relieving any symptoms that could be related to a deficiency of this important vitamin. One of the building blocks of serotonin is the amino acid tryptophan, and one of the building blocks of tryptophan is niacin. Tryptophan also helps maintain healthy levels of niacin within the body. If tryptophan is divided between serotonin production and niacin production, serotonin production may be reduced when niacin levels are inadequate. Supplemental niacin and tryptophan can be beneficial for healthy moods.*

Niacin is important for proper functioning of all cells, including the cells of the brain and nervous system. Niacin has the well-known effect of causing vasodilation, often called the niacin “flush,” which is an opening of small blood vessels (capillaries) for increased blood flow. These are the blood vessels which are of most value in reaching fatty tissues. Healthy blood flow is important for allowing toxins stored in these fatty tissues to be removed into the bloodstream, and processed out of the body. Niacin may also support healthy skin by promoting normal moisture retention, elasticity and tone. Niacin may also support healthy cartilage.*

For a higher dose in a slow-release format, consider our Niacin Sustained Release. For the same dose in a lozenge format for those who have trouble swallowing capsules, consider our Niacin Lozenges.

Suggested Use

Take 1 capsule daily with food or as directed by your healthcare professional.


Children and pregnant or lactating women should consult their healthcare professional prior to use. Do not use if tamper seal is damaged. Consult with a healthcare professional before use if you are using antibiotics, cholesterol-lowering drugs, blood pressure medications, alpha-inhibitors or other medications. Niacin may cause a "flush" feeling including tingling, feeling warm, blushing or turning red (usually on the face, ears, neck, or chest). This reaction is more common for individuals who have not used niacin-containing supplements before, or for those who are sensitive to niacin. It usually subsides in a few minutes to a few hours, depending on the individual. You can reduce your likelihood of experiencing that reaction by eating a meal before or very shortly after taking a supplement containing niacin, drinking plenty of water, and making sure that your dose is appropriate. It may be best to start out with only a portion of a serving and gradually work your way up to your desired dose, allowing your system to acclimate to the niacin. We recommend that you consult with a healthcare professional for help determining the best dose of niacin for your individual needs, and that you talk with your practitioner about any side-effects your experience while using niacin.

Great for flushing
I was directed by my ND to do niacin flushes to treat my hereditary hypercholesterenemia and elevated lipoprotein a. I need to take at least 150mg to flush but I'm glad the pills are in lower dosages so that I can add or remove as needed. Review by Jennifer (Posted on 11/18/2018)
Great for Relieving Brain Zaps
I tried other supermarket brands and this one was superior, it eased the symptoms and made them tolerable. I continue to take when I feel over menthylated. Dr. Bens advice has helped me so much. I am forever grateful. Review by Loretta (Posted on 11/11/2018)
Good Niacin. Helping me with my circulation and I am happy with the results so far. Review by Sean-Pablo (Posted on 9/11/2018)
Excellent Niacin supplement. It has provided the benefits that I needed it to so that my doctor is pleased. Review by Ferdinand (Posted on 9/1/2018)
Very good Niacin. It is superior in quality and I have felt better taking it. Review by Jas (Posted on 8/23/2018)
Wish I had purchased the lozenge
Harder to dose this version of the niacin. My husband doesn't have a flush but doesn't like the reaction he gets. Review by Amy (Posted on 7/27/2018)
Trying to find a lower dose of Niacin for ease in titrating
Very pleased to find a smaller dose of flushing niacin so that I can move up slowly to my optimal dose.

As always, pleased with the design of the pill and the safety measures that Seeking Health provides.

Folate pathway
Taking to help with my folate pathway. Good quality product and I am happy with the results. Review by FJ (Posted on 7/25/2018)
Feel the flush!
Forget the no-flush niacin. It doesn't have the same benefit. After a while you get used to it and it actually feels sort of soothing to me now. I take one or two of these whenever I feel overmethylated (sluggish, low motivation) and it perks me right up. These are smaller and have less filler than the 50 mg niacin I used to use. I love that the capsules are vegetarian too. Review by Holly (Posted on 10/7/2017)
Prefer The Capsule!!
I bought the Niacin in the 50mg capsule form for several reasons. My daughter (7) does not like supplements that she has to suck on ie: lozenges. She has always preferred to take a capsule. She has MTHFR C677T and has struggled with headaches when taking any multi vitamin/supplement. Tests show she need b12 and folate, so in an attempt to start her on this and with school starting, I want to have a capsule of niacin on hand to be able to either open and give her a sprinkle if she has an immediate reaction, or be able to open up the capsule and reduce the amount of niacin she receives as she is sensitive to supplements. I always learn so much from seeking health's site and appreciate the articles and helpful directions to listen to from dr. Ben under some supplements. I have learned more from him than my life time of seeing doctors. I also have to add that I do not worry about ordering from seeking health as their customer service is top notch with wanting one to be happy with their order.
