Vitamatic Vitamin D3 50,000 IU Review

Vitamatic Vitamin D3 50000 IU Weekly Dose comes as 60 veg capsules, with one capsule taken once a week with food or as directed by a healthcare provider. The page says the once-weekly dosing helps with adherence and provides a 60 week supply, which is more than one year. Vitamatic describes vitamin D3 as a very important nutrient for overall healthy muscle function, and says it increases calcium absorption to support stronger bones, teeth, and immune health. The page notes that the vast majority of individuals are deficient in vitamin D, a life-sustaining vitamin. It presents this high-dose form as a way to get the benefits of vitamin D without the risk of unprotected exposure to UVB rays, which it calls a safe and natural approach. The product is made in the USA and is free of sugar, yeast, wheat, egg, artificial colors, flavors, and preservatives. Listed badges on the page include no dairy, no artificial flavors, GMP, lab tested, formulated in the USA, soy free, non-GMO, and gluten free. The ingredients are vitamin D3 as cholecalciferol, cellulose vegetable capsule, rice flour, magnesium stearate, and silicon dioxide. The page is a supplement product listing and is not a substitute for medical advice from a healthcare provider.
