Comparing vitamin d products

Compare the vitamin D amount per daily serving and the units shown on the label. Check whether the formula contains additional nutrients, and review the source and dietary suitability of each product individually.

Oral supplements and topical patches are different product types. The inclusion of a patch here does not establish nutrient absorption or equivalence to an oral supplement. Follow the directions and ingredient information for each specific product.

Check the current product label for directions, ingredients, allergens and suitability. Do not exceed the recommended intake. If you take medication or need advice about suitability, speak with a pharmacist or qualified healthcare professional.

Frequently asked questions

What should I compare on a vitamin D label?

Check whether the formula contains vitamin D2 or D3, the amount per recommended serving and the units used. Labels can show micrograms and international units, so a larger printed number does not necessarily mean a larger quantity. Also check the serving size: a value per drop, tablet or daily serving can describe different quantities.

Is vitamin D with K2 the same as vitamin D on its own?

A combined product includes an additional nutrient and may have different directions and suitability information. Compare the vitamin D amount separately from the K2 amount and read the complete label. If you take prescribed medicines, ask a pharmacist about the exact combined formula rather than assuming it is interchangeable with a vitamin D-only product.

How do I compare vitamin D drops with tablets or capsules?

For drops, identify the labelled volume or number of drops in a serving and use the supplied measuring method. For tablets or capsules, check how many make one serving. Compare the declared vitamin D per recommended serving and the number of servings in the pack, rather than bottle volume or tablet count alone.
