THORNE Niacinamide - 500mg Niacin - Non-Flushing Form of Vitamin B3 - Support Joint Health, Skin Health & Restful Sleep* - Gluten-Free - 180 Capsules

As a woman experiencing pre-menopausal symptoms, I can’t recommend Thorne products enough! Their Niacinamide capsules have been a game changer for me. My holistic provider recommended Thorne as one of the cleanest and most effective supplement brands out there, and I can see why. I feel a noticeable difference in my skin, joint comfort, and overall sense of calm, especially when it comes to restful sleep. It’s hard to find such high-quality, natural supplements, and Thorne truly delivers. Knowing these are gluten-free and formulated without unnecessary additives gives me peace of mind. Highly recommend to anyone looking for clean, effective support!

Top quality! My large breed dog takes this supplement to counteract the skin and fur effects of taking a steroid medication longterm. Last month I decided to save some money and switched him to a lower quality Niacinamide made by a popular brand of vitamins and supplements found at grocery stores. In no time, his fur started thinning out all over his body and his skin became dry and flaky to the point it looked like dandruff. I bought the Thorne brand again to see if this caused the change. Within a week or two, his fur is growing back and skin is no longer dry. I was shocked!! Yes, it’s more expensive but totally worth it!

Love this works well

I only took these for about 2 weeks with my lunch but stopped because my face was starting to get a lot of bumps and break out. I don't normally get break outs (I'm 42 yrs old now) and I didn't have an issue with acne as a teen but started breaking out on my cheeks after taking these. I stopped to see what happens and my face is clearing back up. I had bought these thinking these were the pills my husband's doc was recommended but it was something else. I decided to take these anyways and now have stopped due to the breakouts. I might try them again later down the road but as of right now I would not recommend them since I'm not prone to breakouts but it still caused me breakouts.

Arrived in a timely manner and in good condition.

Non flushing. Great supplement. Good brand

So I've never actually experienced side effects from a vitamin before. At first I didn't even think to attribute what I was feeling to these vitamins, but then when I stopped taking them I noticed all my issues stopped. For me, it gave me a mild headache, nothing to terrible but not pleasant. For me the worst part was I had to pee literally every 20 minutes. It felt like anything I drank would go right through me. I felt super dehydrated. However, I will say I noticed a almost immediate improvement in the tone of my skin. It sucks because I love what it did fir my skin but I cant deal with having to use the bathroom so frequently.

Quality product and the price was fair.
