make sure you read the bottle to see what it says... take wit food, take before meal or on empty stomach and go from there. most things take with some carbs like bread etc

In order to take Vitamin D vitamins, you must take Vitamin K at the same time. This is information that my doctor told me about and he said most people do not know this. Also vitamins bought in stores really are not that effective. The best vitamins are expensive but should be bought from a really good company.

I take vitamin D3 with no side effects. Saltine crackers are usually good. Some people need to take pills with food to help fend off adverse effects. Have you tried taking it with food? Best wishes for you.

I use to get nausea and even vomiting with supplements. I just make sure now to spread them out, as I take several and take them after I’ve eaten a little something. With a little research you may find some that are gentler on the stomach. Best wishes.

I take prescription vitamin D and I've had no bad reaction. Are you taking over the counter D? If you are maybe your doctor can prescribe you the prescription vitamin D. I wish you well and I'm sending gentle hugs!
