Webber Naturals

Webber Naturals Niacin 500 mg, 90 Capsules, No Flush, Vitamin B3 Supplement, Supports Energy Production and Metabolism

Webber Naturals

CA$17.99

More Details
Main highlights
- Vital Nutrient: Niacin is an essential vitamin that helps the body metabolize nutrients and supports energy metabolism and tissue formation. This B vitamin is vital for normal growth and development and helps support good health. Niacin is water- soluble, so it is not stored in the body. This means that a good daily intake is required to prevent deficiency
- No Flush: Niacin (vitamin B3) in the form of inositol hexanicotinate does not cause the warm, red, tingly “niacin flush” often experienced with other vitamin B3 supplements. While the niacin flush is harmless, it can be disconcerting and uncomfortable
- Free Of: Artificial colours, preservatives or sweeteners; no dairy, starch, sugar, wheat, gluten, yeast, soy, corn, egg, fish, shellfish, salt, tree nuts or GMOs
- Easy to Swallow Capsule: This one-per-day supplement can help prevent niacin deficiency and comes in an easier-to-swallow capsule
- Each Capsule Contains: 560 mg of Inositol Hexanicotinate, providing: 500 mg of Niacin and 120 mg of Inositol
