Melatonin Supplements Visit the Store Melatonin Supplements Review: Feel the flush! - I take this as it's been recommended for autoimmune disease as well as heart health. Niacin is vitamin B3 and we need B vitamins. Also, they're water soluble so you cannot overdose. This is not time released so you feel the flush. I was told that it's better for you to have the dose all at once so the capillaries will open more. The flush is kind of hot but I don't mind it, lets me know it's working! Review: a proper niacin product - This one is actual fast-acting niacin, presumably nicotinic acid. It works smoothing-out my irregular heartbeat; have been using niacin for a few decades for this purpose. If considering niacin for health benefits, avoid "Niacinamide" formulations or the time-release products. This is definitely NOT medical advise. I only pass along my own experiences. ## Features - Niacin, also known as vitamin B-3, functions in over 50 metabolic reactions, most of which are enzymatic. - Niacin plays an essential role in the activities of various enzymes involved in the metabolism of carbohydrates and fats, the functioning of the nervous and digestive systems, the manufacturing of sex hormones, and the maintenance of healthy skin.* - Suggested Use: 1 tablet daily. Please see NOTE before using. - Over 40 Years of Trust. Source Naturals was created in 1982 by CEO Ira Goldberg to support everyone’s potential to enjoy optimal health. - Manufactured in the USA.

Niacin is vitamin B3 and we need B vitamins. Also, they're water soluble so you cannot overdose. This is not time released so you feel the flush. I was told that it's better for you to have the dose all at once so the capillaries will open more.

It may not be a one day quick fix, but, there is no quick fix for THC besides synthetic urine, which is morally wrong as it's cheating and deceit. If you haven't smoked in awhile, it will get the THC out of your system super fast. Good tip, buy some at home drug tests, 50 cutoff level, and every day take 500 milligrams of this when you first wake up, don't eat anything, and go and work out hardcore. Drink a gallon of water over the 8 hour period after taking the pill. Make sure to piss a lot too. I did this and my at home tests went from positive to negative after 3 days. It will eventually flush your system completely clean if you use this. It CAN temporarily clean your system out. It gives you a 6 hour negative window starting 45 minutes after taking the pill. But be wary. If you smoked recently, it might not come negative on a test. Just. Make sure to use plenty of drug tests. ## Frequently Bought Together - Source Naturals Niacin 100 mg Vitamin B-3, Non-GMO - 250 Tablets - Source Naturals Niacinamide B-3, 100 mg Dietary Supplement - 250 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.co.za/products/2587916-source-naturals-niacin-vitamin-b-3-non-gmo-100-mg](https://www.desertcart.co.za/products/2587916-source-naturals-niacin-vitamin-b-3-non-gmo-100-mg) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-05*
