Vitamin B3 (Niacinamide) Powder


  • Vitamin B3
  • No skin flush
  • Supports overall health
  • Taste

  • Mixability

Niacinamide (Vitamin B3), though closely related to niacin, does have differing effects. It may improve energy and when used as a topical treatment, could improve the skin's appearance.


Serving Size & Timing

As a dietary supplement, take 100 mg (about 1/32 tsp) to 500 mg (about 3/16 tsp) daily, preferably with a meal (since it increases the production of HCL, which aids digestion further). Niacinamide can be dangerous in larger servings; avoid amounts exceeding 1 gram unless advised by a physician.

Customer Reviews

My dermatologist recommended taking Niacinamide orally for my skin. It has a bitter taste but it dissolves well in water. I take a lot of supplements so it is nice not to have another pill to swallow. I do 500 mg am and pm. *

Great price
B-3 is such an important vitamin, and the Nicotinacide form is the best. Nicotinacide in pill form from most supplement company’s would cost many times more. Great to have bulk powder prices from bulk supplements *

I began reading the book about Niacin from Dr Abram Hoffer, and I began using Niacinamide, it is fabulous for skin disorder and skin beauty, also it works very well for arthritis and as Dr Hoffer says: "peace of mind", so it can be use for mental disorders.
It is very good also use directly on skin, mixing it with a little glycerine or water, and leave on your skin, then refresh, your face will be illuminated.
Bulk Supplements makes all easy, good price, good delivery and best quality!*

Love this product!! I ordered this same product from previously and loved everything about It, not only the quality of the product but its packaging is superb. The packaging is more environmentally sound that the big heavy plastic that so many vitamins are packaged in. Thank you for being an environmentally aware company and providing us consumers with quality products.*

Great product. Will definitely order again!*

Great quality
I use in rose water in a spray bottle for my face to control discoloration. This product works really fast. One week twice a day and discoloration has faded. Will buy again awesome product. *

On 7/30/2018 Inetta said...

like using it on my face and already see good results on my skin. like the quality and convenience of having it in a powder without add filters in it.
like the benefits without the flush.*

No flush - yes!
Niacinamide does the trick without the flush! Great for travel too. Thanks for a great, easy-to-use product!*

On 6/1/2018 Josh said...

Great price
I use it topically on face, neck and hands. I made a 5% solution in rose water. I keep it in the refrigerator and use it as a toner. I spray it on clean skin twice a day, let it dry little, and then follow with a regular moisturizer. After 2 weeks I noticed slight improvements in skin tone - dark spots fading, less redness. I expect it will take a couple of months to get the full effect. If you would like to take it orally as well keep in mind it is quite bitter.*

I am 67 years old and find Niacin as an important part of my daily supplement. I mix it with juice for breakfast.*

On 8/8/2017 Magdy said...

Great stuff
I use this on my skin. I was on a new supplement which was breaking me out. Not through here. I started using this in my with hazel and other items and use it daily. it has really helped clear up the breakouts seriously. It's suppose to help reduce wrinkles as well. I just love this on my skin. and see results after just a couple weeks. Bulk supplements, sells the best pure forms. I am excited of what I will buy next. Berry Extracts I have been reading so much about and see they sell this as well. Top Notch company!*

On 3/25/2017 Jacqui said...

I have noticed more energy since taking this supplement. I seem to have more stamina. Somehow I am also reading the fine print better!
I plan on making a skin cream using this supplement since it is supposed to be good for the skin.*

Aids in wound healing
I find rubbing niacinamide in wounds really speeds healing time. I recommend niacinamide from because their prices are very good and their shipping is quite reliable. I ordered some niacinamide from a different store and I swear the stuff doesn't work. I have no idea what it is!

BTW - eating niacinamide doesn't aid in healing (except maybe the stomach) because it probably reacts to quick. Rubbing it into wounds really does help. Maybe injecting it would speed some kinds of healing.*

Fades wrinkles and dark spots
I reviewed this on Amazon when I first got it. Since I have used it for a few months now, I thought I'd review it again.

I use it all over my body in my 5.5 pH lotion once in a while but use it almost daily as a toner/wash and orally. I used it in my body lotion one evening and could not sleep that night. I didn't do THAT again.

Oral dose 1/8 tsp daily.

2 step toner: 1/4 tsp in 2 ounces water/rose water wiped on with a cotton ball followed by a spray on combo which I allow to dry naturally.
Spray toner:
2 oz water or rose water or aloe vera (if aloe is used may want to back off on the glycerin)
+/- 1/4 tsp glycerin (begin with 1/8 tsp as 1/4 may be too tacky)
1 tsp niacinamide
few drops of essential oils good for skin
Shake and spray
I wake up with soft moist skin every morning after using this.

I also wash nightly with a squirt of a 5.5 pH face wash and a couple pinches of niacinamide using a rotating brush on face, neck and decolletage. Leave on for about 5 mins then rinse with warm water. Follow up with above toners. If using vitamin C cream or any acidic face cream, allow at least 1/2 hour before applying.

May follow up with niacinamide mixed with a 5.5 pH cream - layering the niacinamide.

With following the above routine I notice that my skin is softer and dark spots from old acne breakouts have faded considerably. Wrinkles are less noticeable and I look younger. I even went out without makeup today (only powder). I will continue to use the routine but may mix it up a little with some alpha arbutin for more fading of my dark spots.

Too bad BS doesn't carry straight skin care products also. That would be awesome.

Vitamin B3 (Niacinamide) Powder for Skin Care
Very pleased how well the powder mixes with the other ingredients for a moisturizer. A great improvement on the quality of my skin.*

Vitamin B3 (Niacinamide) Powder
First time ordering this version of B3. The powder mixes extremely well. It has a bitter taste, but once mixed with juice or protein powder it is unnoticeable. I get tones of energy without the jitters which was good and bad at first. I liked the energy, but when I first tried it I drank some around 7 pm and could not fall asleep. lol...

I highly recommend this product.*

On 7/11/2016 Mike R said...

Great Product
This is a great product and Bulk Supplements has a superior quality. I will definitely be buying this and other products from them. *

On 7/5/2016 Amanda said...

great for both topical and oral use
I use this niacinamide powder both topically (applied to skin) and orally. I use it primarily because it has impressive skin protecting and enhancing qualities, through both topical and oral routes.

For oral use, I use between 500mg-1g daily split into AM and PM doses. I simply place water in my mouth, then dump powder in my mouth and swallow.

For topical use, I dissolve powder in any base (lotion, serum) that has some water in it, as niacinamide is highly water soluble and is very easy to incorporate into topical applications. It is white and non-oily, so it's very cosmetically acceptable. I use at a rate of 1-2% (1-2g of niacinamide per 98-99g of base) and apply daily.*

Niacinamide Powder (Capsules)
Once again Bulk have delivered amazing service. Their prices are great but more importantly this product is of high quality. The website is simple to use and I'm always surprised at how quickly the products are delivered.*

Niacinamide powder
Nicely packaged, easy to dissolve. I use it to make a skincare product - 5% niacinamide + 5% vitamin C + a little glycerin - to finally stop spontaneous bruising (purpura) on forearms. So far, looks like a real solution to the problem.*

Niacinamide Vitamin B for my skin care
This came so fast I couldn't believe it! This site is also has the very best price I have seen anywhere. And believe me, I scoured the internet so don't waste your time! The packaging was strong and secure. I made some face cream with this and I love it. I can already see a change in my skin. Thanks so much for the speedy service!*

On 10/28/2015 Christine said...

Good product
Product came quickly and worked well. It's kind of clumpy and seems a little moist even though it's a powder, if that makes sense. I made the mistake of taking it straight from the package, no mixing, and it tastes horrible so I don't recommend you do that. Unless you don't care, then go for it. With that being said, the energy I get from this more than makes up for the taste. Good product, fast delivery. I highly recommend this supplement.*

On 10/22/2015 Valerie said...

Great product
Good packaging, arrived quickly. This is a much more convenient and cost-effective source of niacinamide.*

Dissolves well
I use this niacinamide powder in my skin care products. It dissolves well and doesn't cause flushing like niacin powder does.*

On 7/23/2015 Toni said...

I ordered this product after hearing that this form of niacin can help relieve anxiety. I had to lower the dose after the first day because the effects aren't immediate but I felt them very strongly within 12 hours. A secret gem for anxiety along with l-theanine and taurine.*

On 7/20/2015 Joseph said...

Niacinamide vs Niacin
I was originally taking the niacin, and understandably could never get up to a 500 mg dose due to the intense flushing. I really believed that I could tolerate the flushing, but never did. The niacinamide is soooo much easier to take. No building up. I could take the required dose immediately. Love bulk supplements, because they have no added ingredients! Thank you!*

On 7/15/2015 Dawn said...

Excellent Quality!
I have a capsule maker use this B3 powder to make them with. It has many uses in powder form as DIY face and body serums or taken internally as a much needed supplement. Love ordering from Bulk Supplements. Quality stuff at the right price!*

On 6/17/2015 Leslie said...

Speedy Delivery
Great price for the product. I will reorder all the time and certainly will expand my purchases in general! *

Couldn't be happier
i purchased this vitamin b3 to add to my homemade body scrub. I read that it helps lighten skin and I needed help with my brightening knees. It actually works. I also added some to my face cream for nighttime. Love it. *

Bulk has the fastest delivery ! I use this in a DIY serum. It dissolves easily. I couldn't be happier .

On 4/13/2015 Carrie said...

Love It!
I use this as part of my nootropics stack and really notice the difference. I pack the powder in capsules and use it twice a day. I have bought from other suppliers but with Bulksupplements seems to be of a higher purity.

Helps brain problems?
I bought niacinamide because a highly respected natural doctor recommended it for brain issues (memory, concentration, etc.) in high doses. I have not been taking it long enough to see a difference, but I have faith in this doctor, so I fully expect improvement in the next few weeks. I have had no side effects.*

On 3/17/2015 Alice said...

Great niacinimide
I ordered niacinimide powder. I received product very quickly which is always a plus. I am using niacinimide powder to make my own niacinimide facial serum. So far, so good! I love the way it feels going on my skin!The powder dissolves very good and I love the fact that it's pure powder with no additives and it was at a great price. I will definitely be purchasing again from bulksupplements.*

On 3/14/2015 Yvette said...

this product is really good for the skin; after drinking for two weeks, you will see the difference.*

work well topical to clear acne marks*

On 12/4/2014 Paulette said...

This is one of three supplements I ordered just over a week ago. My order was for Niacinimide, MSM & Zinc, and although I have only been taking them by the suggested doses ( which are very tiny) for a few days, I have really noticed a big difference in how I feel over all. I didn't expect to wake up four days later, feeling as good as I did but I did, and I can only describe it as I felt like my body was not working as hard to function. I had more energy, and my joints and tissues felt better. I add some of all of them to my own serums and creams and can say my skin is looking much better as well. Just over all, I feel and look better. These products are very pure and clean, and that is obvious as soon as you open the foil zip lock bags, and look inside. I am now placing my second order, as I am in the process of building my own personalized daily supplements that are pure, and contain ONLY the things I need, not those costly ones that are filled with salts and sugars containing only scant amounts of what the label says you need. Taking these you get only the supps, nothing else. I don't need or want all of the other stuff. These prices are amazing as well and when you think about what you get, well, I will just say I am thankful for finding BS!*

Naicinamide powder
I received the packaging on time, the packing is excellent quality with lots of information on the product. It mixes well with my other ingredients, no problems expected. I have not had enough time to notice changes or effects of ingesting it yet, but expect known results as this is a pure substance! Will buy more!*

On 8/19/2014 Les M said...

Mixes very well, arrived very quickly, and has had a noticeable effect on the quality of my skin within 2 weeks of use. This powder does taste very bitter, but it washes off your tongue quickly with any liquid so it doesn't linger.*

Nice fine powder. Super fast shipping. Great experience overall!*

niacinamide powder
This product is a very fine powder which makes it easy to mix with the other powders that I use to make a custom multivitamin powder for our own use. Other niacinamide powders I have used were much courser and did not mix as well. I also like the vacuum packaging and the inclusion of the manufacture date.*
