Thank you for your inquiry. Paul, at Endurance Products Company. **Q: Are your products independent 3rd party tested?** A: I do not know, but if the questioner wants to research this on the internet, feel free to do so. I just know that this product bywords very well for me and I’ve been taking the 250 mg. For years. **Q: Hi is this niacin or niacinamide? Thanks so much!** A: Endur-acin is niacin in the form of nicotinic acid. Our sustained release Niacinamide brand is Endur-amide. **Q: Is it safe to cut the tablets in half? — Michelle** A: These are time released. If you need 125mg, then order 125mg. If you cut them in half, they don't work the same. We started with 500mg which was too much, so we now buy 250mg and take them morning and evening. That works a lot better.I hope this helps. Ü. ## Customer Reviews ### ⭐⭐⭐⭐⭐ GOOD VALUE *by on Reviewed in the United States 7 July 2026* One time purchase. ### ⭐⭐⭐⭐⭐ The real no flushing niacin. *by on Reviewed in the United States 18 November 2025* I had tried a few other slow release no flushing niacin products, but I often had really bad flushing once or twice a week sometimes to the point that it felt like my skin was on fire. Endur-acin is the real deal. Absolutely no flushing most of the time and the few times I had flushing it was very minor, even at the same dosage. Plus it is real Nicotinic Acid which is the form that helps control cholesterol. ### ⭐⭐⭐⭐ No Flushing - Yet *by on Reviewed in the United States 6 December 2021* I had previously taken a 500mg slo-release Niacin version. I didn’t make the association at first but after about 3-4 days I experienced a severe hot flash. My skin became reddened and I was so uncomfortable I had to go outside because the outdoor temp was in the 50s. However even outside when the sun hit me I thought my skin was going to burn off. Thought I was turning into a vampire.So I’ve been trying this at 250mg dosage starting at every other day. No issues. Now I’m at every day - no issues. So my 4 star rating is for easy to swallow, low cost, no severe hot flash. If later on there has been an actual impact on my cholesterol I’d give this 5 stars. My cholesterol isn’t high on an absolute basis but it was suggested to me that at my age I might benefit from a statin. I’m not fond of that idea, I find that losing weight and keeping it at a good level has more impact, which I’ve done. If this Niacin improves my cholesterol even more then I’ll be more than satisfied. If necessary I could increase it to 2 a day to equal 500mg but I’m not going to risk the severe hot flash. ## Frequently Bought Together - Endurance Products ENDUR-ACIN 250mg Niacin - Extended Release for Optimal Absorption & Low-Flush Vitamin B-3, 200 Tablets - Non-GMO, Vegan, Gluten Free Company - Endurance Products ENDUR-ACIN, Extended Release Niacin for Optimal Absorption & Low-Flush Vitamin B3 Niacin 500mg, Premium Niacin Supplement Made in USA, 200 Tablets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/307313168-endur-acin-low-flushing-extended-release-niacin-250mg-tablets-190ml](https://www.desertcart.pt/products/307313168-endur-acin-low-flushing-extended-release-niacin-250mg-tablets-190ml) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-24*
