NOW Vitamin D-3 Review

NOW Vitamin D3 1000 IU Softgels are presented as a supplement that supplies vitamin D in a highly absorbable liquid softgel form. The product is listed with the tagline Bone & Immune Health and the claims Supports Healthy Teeth and Promotes Muscle Health, which the page notes have not been evaluated by the Food and Drug Administration. Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. The page explains that it is not abundant in food, and that as more people avoid sun exposure, vitamin D supplementation becomes even more necessary to ensure that the body receives an adequate supply. Each softgel provides 25 mcg (1,000 IU) of vitamin D as D3 cholecalciferol from lanolin, which the page lists as 125% of the Daily Value. The product is offered in a 180 softgel bottle at $8.99 and a 360 softgel bottle at $16.99, with SKUs 0365 and 0375 respectively. The suggested usage is to take 1 softgel daily with a meal. The label advises storing the product in a cool, dry place after opening. The caution statement says it is for adults only, and that adults should consult a physician if pregnant or nursing, taking medication, or having a medical condition, and to keep out of reach of children. The other ingredients are extra virgin olive oil, a softgel capsule of bovine gelatin (BSE-free), glycerin and water, and safflower oil. The page states the product is not manufactured with yeast, wheat, gluten, soy, corn, milk, egg, fish, shellfish, tree nut or sesame ingredients, but is produced in a GMP facility that processes other ingredients containing these allergens. Certifications and labels shown include Halal, Intertek GMP Supplement Certification, Kosher (Triangle K, contains gelatin), and Non-GMO, along with made without corn, dairy, eggs, soy, and gluten free marks and a low sodium mark. Natural color variation may occur in this product. The page says the product is made and quality tested in the USA with globally sourced ingredients. NOW is described as family owned since 1968, and the bottle is stated to be made from 100% PCR (post-consumer recycled) resin. A short video titled Vitamin-D Supplement Basics is linked on the page. The page also lists the product under the Vitamin D category and shows related NOW vitamin D products, including chewables, gummies, and dry veg capsules, which are separate listings with their own forms.
