Solgar Vitamin D3 Review

Solgar Vitamin D3 (Cholecalciferol) 25 mcg (1000 IU) Softgels is presented as a non-GMO, gluten-free and dairy-free supplement. The page explains that people in the northern hemisphere, or those who wear lots of sunscreen, may not produce enough of the sunshine vitamin on their own, and that vitamin D is not abundant in most foods.

According to the page, one Solgar Vitamin D3 softgel taken daily helps maintain a healthy immune system and good general health, strong bones and teeth, and optimal nerve and muscle function. Because vitamin D is fat soluble, the brand describes its oil-based softgels as easy to swallow and absorb. The product is available in 100 softgel and 250 softgel sizes, with Buy Online links to Amazon for each size. The suggested use for adults is one softgel twice daily, preferably with meals, or as directed by a healthcare practitioner. The Supplement Facts panel lists a serving size of one softgel with 25 mcg (1000 IU) of Vitamin D3 at 125% Daily Value. The ingredients listed are safflower oil, gelatin, vegetable glycerin, fish liver oil and cholecalciferol, and the label states it contains fish (cod, haddock, pollock). The product is free of gluten, wheat, yeast, sugar, salt, artificial flavors, artificial sweeteners and artificial colors. The warnings advise pregnant or nursing women, people taking medications, or anyone with a medical condition to consult a healthcare practitioner before use, to stop use and consult a practitioner if adverse reactions occur, to keep out of reach of children, to store at room temperature, and not to use if the outer bottle seal is missing or damaged. The page also describes Solgar as a brand since 1947 committed to quality, health and well-being, stating that its formulas are science-backed, made in small batches with in-house manufacturing, responsibly sourced, and free of artificial ingredients or fillers. USP water filtration and HEPA air filtration are highlighted as quality standards.
