Best Vitamin D Supplements Buying Guide
Before choosing the best vitamin D supplement you should consider following options:
1. Vitamin D3 vs. Vitamin D2: The most common form of vitamin D is D3, also known as cholecalciferol. It is produced in the skin upon exposure to sunlight.
Vitamin D2 is a form of vitamin D thatโs mostly produced from irradiated yeast or from fish or fungus extracts.
According to Dr. Michael F. Holick, a professor of medicine, physiology and biophysics at Boston University Medical Center and one of the worldโs leading experts on vitamin D, thereโs no real difference between vitamin D3 and D2.
โThe distinction is artificial,โ says Dr. Holick. โThe only difference is that D2 is typically used in supplements in India, whereas D3 is used in supplements in the rest of the world.โ
2. Calcidiol vs. Calcitriol: Vitamin D is ultimately converted into either calcidiol (also known as 25-hydroxyvitamin D) or calcitriol (1,25 dihydroxyvitamin D). Calcidiol is the inactive form of vitamin D, while calcitriol is the active form.
According to Dr. Holick, โthe majority of doctors will measure and treat based on calcidiol levels, because most people will convert calcidiol to calcitriol.โ
3. Vitamin D3 in High-Dose vs. Low-Dose: Vitamin D3 supplements are available in high- and low-dose forms. High-dose vitamin D3 supplements contain a higher amount of vitamin D3 and are generally used for treating vitamin D deficiency or for increasing bone health.
Low-dose vitamin D3 supplements contain a smaller amount of vitamin D3 and are generally used for supporting overall health.
4. Vitamin D3 in Capsule vs. Liquid: Vitamin D3 supplements are available in capsule and liquid forms. Capsule forms are most common, but some people may prefer liquid forms.
Liquid forms may be easier to swallow and absorb. Some people may also prefer liquid forms because they can add the liquid form to their smoothie or juice, says Dr. Holick.
5. Vitamin D3 in High-Potency vs. Low-Potency: Vitamin D3 supplements are available in different potencies. High-potency forms contain between 2000 and 5000 IU of vitamin D3 per capsule or teaspoon.
Low-potency forms contain between 400 and 1000 IU. โIf you take a higher dose, you will get the appropriate amount of vitamin D3 faster,โ says Dr. Holick.
But taking a high dose of vitamin D3 may cause a โfishyโ odor in your sweat and urine, says Dr. Holick. โThis is harmless and will go away as your body adjusts to the higher dose.โ
