I took before another brand but nothing happened to me but woth this I had rashes and allergic signs ### ⭐⭐⭐ كم من حبه ناخذ بيوم *by S***D on 2 July 2021* انه جيد يجعلك نشيط ### ⭐⭐⭐⭐⭐ The flush is good for you embrace it. *by M***A on 15 May 2025* My go to niacin tablets. Have tried other brands but these always seem to give the best results. Slight scent to them that i can only describe as the smell of the niacin flush feeling. Maybe because the smell of the tablets makes me instantly remeber the flush. Nice dose to start with 100mg if just starting nacin. On an empty stomach the flushing can come on quick but for me it doesnt last cery long (approx 30 minutes) this is dependant on you though as everybody is different. Works fast. My skin always feels so nice afterwards, like it tightened up a little bit. Gives a slight "you're glowing" look (most likely because it increases blood flow to the skin by way of the nacin flush. The flushing can be uncomfortable but the no flush version doesnt provide the same benefits as this type. Small tablet that is easy to swallow. Considered low strength. But a good everyday dose. ## Frequently Bought Together - 21st Century Niacin Tablets, 100 mg, 110 Count - 21st Century Slow Release Iron Tablets, 60 Count - 21st Century Folic Acid 400 mcg Tablets, 250 Count --- ## 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.com.pa/products/252393106-21st-century-niacin-100mg-110-tablets](https://www.desertcart.com.pa/products/252393106-21st-century-niacin-100mg-110-tablets) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-08-06*
