Packaged in 180 vegan capsules, it supports sustained energy and cardiovascular health without the typical niacin flush, making it a top-rated choice for health-conscious adults. ## Description Double Strength Flush-Free Niacin (Vitamin B-3) is an essential B-complex vitamin. Flush-free niacin contains inositol hexanicotinate, a form of niacin that consists of six molecules of niacin linked to a single inositol molecule. It is slowly broken down in the body to yield free niacin and inositol. This gradual release of niacin allows for true niacin activity without the characteristic niacin flush that many people cannot tolerate. This product has twice the niacin (500 mg per capsule) as in our regular strength product (250 mg per capsule). Natural color variation may occur in this product. ## Features - Flush free niacin 500mg 180 vcaps by now foods - NOWSUPPVitamin-Vitamins- 180VCAPS - Now foods product upc : 733739005007 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0041VJLTK | | ASIN | B0041VJLTK | | Age Range Description | Adult | | Allergen Information | Allergen-Free | | Best Sellers Rank | #42,204 in Health ( See Top 100 in Health ) #397 in Vitamin B Supplements | | Brand Name | NOW | | Color | Off White | | Customer Reviews | 4.7 4.7 out of 5 stars (1,081) | | Customer reviews | 4.7 4.7 out of 5 stars (1,081) | | Department | Health and Beauty>Health and Wellness | | Diet Type | Vegetarian | | Dosage Form | Tablet | | Flavor | Unflavored | | Global Trade Identification Number | 00733739005007 | | Is Discontinued By Manufacturer | No | | Item Dimensions | 7.1 x 7.1 x 13 centimeters | | Item Form | Capsule | | Item Weight | 113 g | | Item model number | 0500 | | Manufacturer | NOW Sports - Nutrition and Wellness | | Manufacturer | NOW Sports - Nutrition and Wellness | | Manufacturer Part Number | 0500 | | Material Type Free | en_AE | | Model Name | Niacin (Vitamin B-3) 500 mg, Flush-Free, Double Strength | | Model Number | 0500 | | Number of Items | 1 | | Primary Supplement Type | B-Complex | | Product Benefits | Energy Management | | Product Dimensions | 7.14 x 7.14 x 13.03 cm; 113.4 g | | Specific Uses For Product | Brain | | UPC | 733739005007 | | Unit Count | 180 Count | ## Product Details - **Brand:** NOW - **Diet type:** Vegetarian - **Flavour:** Unflavored - **Item form:** Capsule - **Primary supplement type:** B-Complex ## Images ![Supplements, Niacin (Vitamin B-3) 500 mg, Flush-Free, Double Strength, Nutritional Health, 180 Veg Capsules - Image 1](https://m.media-amazon.com/images/I/71RZgZlBhhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Vgood *by D***S on 22 June 2024* Always use ### ⭐⭐⭐⭐⭐ Review *by ζ·±***瀬 on 12 January 2026* ε₯εΊ·γ«ε½Ήη«‹γ£γ¦γ„γ¦γ€ζ„Ÿθ¬γ—γ¦γ„γΎγ™γ€‚ ### ⭐⭐⭐⭐⭐ Review *by G***E on 23 December 2025* Nice fresh pills ## Frequently Bought Together - NOW Foods Supplements, Niacin (Vitamin B-3) 500 mg, Flush-Free, Double Strength, Nutritional Health, 180 Veg Capsules - NOW Foods Supplements, Vitamin D-3 5,000 IU, High Potency, Structural Support*, 240 Softgels - NOW Supplements, Berberine Glucose Support, Combined with MCT Oil for Optimal Berberine Absorption, 90 Softgels --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/275809952-supplements-niacin-vitamin-b-3-500-mg-flush-free-double](https://www.desertcart.co.th/products/275809952-supplements-niacin-vitamin-b-3-500-mg-flush-free-double) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-11*
