Vitamin D3 Supplements
This page contains a comprehensive list of vitamin D supplements including the Vitamin D3 Blog’s recommendations. All recommendations consist of vitamin D3 (cholecalciferol), the natural form of the vitamin/hormone. D3 is bioavailable, and is the same form of the nutrient obtained through exposure to sunlight.
Vitamin D2 (ergocalciferol) is synthetic. It’s made inside of a laboratory, and its bioavailability is nowhere near that if D3. D2 also carries more risk than D3 in the event of an accidental (or intentional) overdose, or accidental consumption of excessive amounts, a phenomenon known as vitamin D toxicity.
Vitamin D2 is still used in some supplements, so it’s imperative to read the label and make sure the product you’re buying is D3 (cholecalciferol) and not D2 (ergocalciferol). It is the recommendation of this author to purchase vitamin D3 supplements online or at a health clinic / doctor’s office, where you’ll be able to buy medical-grade brands not available at grocery stores, pharmacies or GNC-type businesses.
Vitamin D deficiency and insufficiency are common across the globe, according to the National Institutes of Health. Vitamin D deficiency/insufficiency have been linked to over 50 serious illnesses, diseases and adverse conditions.
