Is it okay to take vitamins on an empty stomach?

I'd say it depends on the type of vitamin, honestly. Fat-soluble ones like vitamins A, D, E, K are better taken with some food since your body absorbs them better that way, but water-soluble ones like B and C are generally okay on an empty stomach. Some people find certain vitamins make them feel a bit nauseous without food though, so if your stomach feels off, just have a light snack with it to be safe. If you're taking specific supplements for pregnancy or postpartum, might be good to check with your PD or pharmacist about the best way to take them.

For me I do take vitamins on an empty stomach. However if you are concerned, you can eat something light like biscuits, bread or drink milo before taking your vitamins.
