Can multi-vitamins be taken at night & still be effective? I have become severely anemic (to the extent of needing blood transfusions) but cannot tolerate vitamins throughout the day. I becomevso nauseous and shaking after taking them that I am unable to function. Please offer solutions that have worked that I may try. Thank you!

yes - they should be fine regardless of when you take them.

On a related issue, although the current iron form I take (carbonyl) doesn't upset my stomach, i started taking iron before bed because the original type I was taking DID bother my stomach - taking it before bed helped with that (and I still take my iron before bed - just out of habit at this point)). So I don't see a reason why you can't take a multi before bed.

I agree that it doesn’t matter what time you take it of the day but to ideally avoid the nausea alltogether have you tried taking a vitamin with lower doses and just take it twice a day?

I was told to take vitamins with food to help with absorption. I find that taking it with food helps with the nausea. I take my multivitamin at night, but I eat a good snack with it. It can still make me throw up if I don't have enough food in my stomach!

Just don’t take calcium supplements within 2 hours of your iron supplement. Calcium inhibits the absorption of iron.

So when i first started taking them it was making me very nauseous. The nutritionist told me to take the multivitamin with iron at night before bed along with a small snack. That helped a ton.
