BulkSupplements.com Niacinamide Powder - Vitamin B3 Powder, Niacinamide Supplement, Niacinamide 500mg - B3 Vitamins for Skin, Gluten Free, 500mg per Serving, 5kg (11 lbs) (Pack of 5)

This niacinamide powder is excellent and very pure. It dissolves well, has no bad smell, and works quickly when added to my skincare mix. I’ve noticed smoother skin and less irritation after just a few uses. The quality is consistent, the price is good, and a small amount goes a long way. I’m very satisfied with this product.

I love this stuff for what it does to my skin! I use it topically in my face products. I mix it in toners and lotions (sometimes even my spf). Topical niacinamide has been proven to be a somewhat effective anti-aging/acne treatment in numerous studies (so have vitamin c and green tea). I like it because i have sensitive skin but I find it calming and it definitely fades skin discoloration over time. I also feel like it makes my skin *behave* better (stays better moisturized but not greasy), if that makes any sense. I know products from Olay and Cerave (to name a few) contain niacinamide but they break me out so I can't use them. Most studies used it at a 5% concentration (so 1 to 20 ratio *thank you Viking Fan) and it works best at a PH of 5-6 (so don't bother mixing it with AHA or BHA). You don't have to mix it with anything special; you can just mix it with water and use it as a toner (if you don't use a preservative you should make it every day lest it go bad on you). Keep in mind, if you go any higher than 5% you may get a flushing effect--in fact you might get a flushing effect even at 5% if you're sensitive to it (some people are and while some people eventually grow more tolerant some people just can't use niacinamide without a bad reaction). Lots of people like to mix it with with N-Acetyl Glucosamine Powder (25 gm) Reduces hyperpigmentation Improves skin tone . To give you some ideas of how to use it, this has always been a popular recipe on Makeupalley dot com: "* 85 ml distilled witch hazel (Boots brand right now, which contains approximately 14% alcohol, as such, no preservative is required) * 10 ml vegetable glycerin * 5 g (approximately 1.5 teaspoons for those who don't/won't weigh it out - I prefer to weight it) niacinamide powder."--(i think it's "JoshuaP's" recipe) This is another amazon reviewer's recipe ("Gattu"): 5 tsp. rose water 10 drops of licorice extract ½ tsp. Glucosamine (5%) --BulkSupplements ½ tsp. Niacinamide (5%) --Nature and Nurture ½ tsp. Glycerin ½ tsp aloe gel ( I almost took 1 tsp) 2 tsp vitamin C ester powder (20%) --BulkSupplements Of course you can also just mix it with water and spray or pat on your face... Sometimes i've mixed it with other products and toners (like Thayer's Witch Hazel). Sometimes i've even just scooped a bit out and mixed it with the daily squirt of my face lotion or SPF (very unscientific, of me). This stuff dissolves really well, so its really versatile.

I love this brand seller because you get both quantity for a good price. It’s not all the fancy packaging but it’s suffices because it’s a Ziploc bag and overall they have like good deals and if you subscribe if you get some more discount when you get your stuff shipped on a regular basis by this store and the seller in this brand has like a diverse wide variety of supplements to take. I highly recommend bulk supplements because of the variety the amount you get of product for a good amount of your money like you get your moneys worth definitely worth the purchase and they have quick shipping and tons of products to choose from recommend highly highly highly recommend

A few years ago, I purchased a cream that contained niacin. I loved the cream and its effectiveness, however, it became very costly and I had to stop buying it. When I saw Bulk Supplement Pure Vitamin B3 (Niacinamide) Powder on Amazon, and after reading the many favorable reviews, I decided to try to make my own concoction. I am trying to get rid of some sunspots on my skin. I mixed a little niacinamide powder with some aloe vera juice in a 2 oz bottle and have been applying it with a cotton ball after I wash my face each night. I decided to mix just enough that would last me a week or so and make a fresh batch each week. I also mixed about ¼ teaspoon of the niacinamide powder in one of my small jars of face creams I had on hand and have been applying it both morning and evening. I noticed that the addition of the niacinamide in the face cream has made the cream much more effective and it now reminds me of the niacin cream that I used to buy because it has a similar scent and, not only that, it is producing the same results. It has only been 10 days since I started using this cream, but so far I am loving the results! My skin is a lot smoother and feels so much softer. No breakouts and no flushing, just smoother and brighter-looking skin. I do not know the percentage of solution I am making, but I do know that it is definitely working for me. I am hoping that with continued use, my sun spots and hyperpigmentation will disappear. I also plan to use this product as a dietary supplement to boost my energy level by mixing some in my smoothies. I look forward to purchasing more products from BulkSupplements.

Fast shipping, on time, arrived in perfect condition. The product seems fresh--smells like vitamin B! It comes in a sturdy, moisture-proof resealable bag, same as pictured...do be VERY careful to hold it upright and tap any loose powder down from the top edge BEFORE you tear it off! I didn't think to do that, but of course during shipping quite a lot of powder had migrated there...yes, I got a big POOF! of powder in my face. And on my counter. And floor. *sigh* Oh well, my own dumb fault, so I wasn't upset, just annoyed with myself! I don't feel I can rate this a 5 star yet, as I haven't had it long (less than 2 weeks) and so far have only mixed a bit with some neutral PH lotion to use on my face & body. It's too soon to know if it's affecting any changes in my skin. I have not used it internally, although I may do that too eventually. I have very sensitive skin but have had no adverse reactions at all from my homemade mix (about 4%), which is good and what I had expected--B3 as niacinamide isn't supposed to provoke side effects, generally, if used with a proper carrier. If/when I see any kind of positive change in my skin and/or health from using the product, I will certainly upgrade my rating by that last star! Until then I will leave it at "good customer experience, apparently a good product (within a limited use application)."

I had heard great things about Niacinamide from youtube gurus about how it helps lighten dark spots and brighten up your skin. So I ordered this product from Bulk supplements and now that its been more than a month of me using it in my DIY serum, I can definitely say this is working as per my expectations or i would say maybe more. But it could be also because of the combination of other ingredients(also from Bulksupplements) in the serum that I add in the serum which might be making it work even more. Here's my DIY recipe for "Vit-C + Niacinamide+N-Acetyl Glucosamine Serum": 5 tsp. rose water 10 drops of licorice extract ½ tsp. Glucosamine (5%) --BulkSupplements ½ tsp. Niacinamide (5%) --Nature and Nurture ½ tsp. Glycerin ½ tsp aloe gel ( I almost took 1 tsp) 2 tsp vitamin C ester powder (20%) --BulkSupplements **Please do your own research before using the above recipe as I am in no way a chemist or anything. I came up with this recipe by researching online as there are tons of DIY niacinamide recipes posted and this is what suits my needs. With this above combination, I was able to see instant brightness on my face within a week which was otherwise very dull looking all the time with dark spots left behind from acne. FYI - I have Asian-Indian medium-olive skin with acne spots and some clogged pores. After a month of using this serum my skin feels smoother day by day and not to mention the scars that are fading dramatically. Also I do notice my pore size getting smaller as well and even my husband commented on my skin improvement which let me tell u says a lot since he never notices anything. I am very very very happy with the results and i will definitely be buying my supplies once I run out of it from bulksupplements as I know for sure their products are in pure form and they WORK.

Always satisfied with their supplements. Good quality and pure. ❤️

Very clean and works well - mix 1/2 tsp with fav basic (nightime) moisturizer, warm washclothe to face, apply cream and enjoy rejuvination overnight. For AM, warm washclothe to face, mix ratio of 1gm ascorbic acid to 10 gm distilled water, apply liberally to face (ratio for reference, 1:10). You just made Vit-C Serum and saved a small fortune $$$. Slight sting upon application, but very effective.
