Review: Wow! - I started off with the flush-free version of Niacin. After researching that the flush-free doesn't offer as many cardiovascular benefits as regular niacin, I decided to give this product a try. I probably should have started off with 250mg from a different product and worked my way up to this product. This stuff will make you flush hard. I feel a tingle in my ears and I know its coming. After 10-15 minutes, I look like I just got back from the beach without sunscreen. Interestingly enough, it feels JUST like a sunburn. It's very uncomfortable, but only lasts about 45 minutes. From what I understand - the flush diminishes after a month of use. If you are not building up and want to jump in like I did, you may want to take an 81mg of aspirin 30 minutes prior to taking this for a reduced flush effect. Update: I am almost done with my first bottle, a couple things I want to note - I shop heavily based on user ratings of products, this product is absolutely fantastic and for those leaving low ratings due to the crazy flush they got is absolutely ridiculous. Regarding the flush - it is quite powerful and uncomfortable at first. It took about 2 weeks of muscling through it before the flush was barely noticeable. About a month in, I don't even flush for more than 5 minutes. At the end of my supply, I don't flush at all. I can tell that it's hitting me because my mouth gets kind of dry and I feel a tingle sensation in my tongue. If you can make it past the two week mark when the Niacin levels equalize in your blood stream and your liver isn't shocked to hell from the flood of Niacin, this product is absolutely fantastic.
Review: High-Quality Niacin Supplement - Effective B3 Support! - Effectiveness: This Horbäach Niacin has been excellent for supporting my cardiovascular health and energy levels as part of my daily vitamin routine. The 500mg dosage provides substantial B3 support, and I've noticed improved energy and overall wellness since incorporating this into my supplement regimen. The flushing effect is expected with this form of niacin and indicates the supplement is working effectively - the temporary warm sensation and skin redness are normal responses that typically diminish as your body adjusts. I appreciate having a pure, effective form of vitamin B3 without unnecessary additives or fillers. The capsule format makes it easy to take consistently as part of my morning routine. Quality: Horbäach has built a solid reputation for quality supplements, and this niacin maintains their high manufacturing standards. The non-GMO and gluten-free formulation gives me confidence about ingredient purity and safety for those with dietary sensitivities. The capsules are well-made and dissolve properly without causing stomach upset when taken with food as recommended. The 100-capsule bottle provides excellent value for extended supplementation, and the packaging protects product integrity throughout its shelf life. The manufacturing quality ensures consistent potency and reliability across different bottles. Value for Money: This niacin supplement provides outstanding value when you consider the high potency and quality formulation at a very reasonable price point. The 100-capsule supply offers excellent coverage for over three months of daily supplementation, making the cost per dose very economical. The cardiovascular and energy support benefits make this a worthwhile investment in overall health maintenance. The pure, effective formulation eliminates the need for multiple B-vitamin products, making this more cost-effective than buying separate supplements. The quality and potency justify the investment for serious nutritional supplementation. This niacin supplement has become an important part of my daily vitamin routine and provides reliable B3 support. Recommend consulting with healthcare providers about incorporating niacin supplementation, especially regarding the flushing effects and proper dosing!

### ⭐ Scary Allergic Reaction
*by A***. on February 5, 2026*

I had a very scary allergic reaction to this. It was slow to onset, but then my whole body was covered in splotchy red hives and burning. My throat started to close up. The reaction lasted for several hours even after taking Benadryl to reverse the effects. I considered going to the emergency room. I immediately threw the pills away. A huge waste of money. DO NOT PURCHASE.
