Many of us take vitamin D to feel better, especially in winter. But a new study shows that not all vitamin D supplements work the same way.
What's new
Scientists found that taking vitamin D2 can actually lower the body's levels of vitamin D3. Vitamin D3 is the form your skin makes from sunlight. It is also better at boosting your overall vitamin D. Earlier research also hints that vitamin D3 may give your immune system stronger help against viruses and bacteria.
What it means for you
If you take a vitamin D supplement, it is worth knowing which type you are using. This one new study does not prove cause and effect, but it does raise a question. You do not need to panic. Just be aware that the kind of vitamin D you choose may matter.
One small thing to try
Before you buy your next bottle, check the label. If you are not sure what type you have, or what is best for you, ask your doctor or pharmacist. They can help you pick a supplement that fits your needs. And remember, getting a little sunlight, when safe, is a natural way to support your vitamin D levels too.
