Why Vitamins Make Me Nauseous?

You're taking vitamins on an empty stomach.
Vitamins that are more acidic in nature ― like vitamin C or folate ― may cause nausea if they're consumed on an empty stomach, Poppers told HuffPost.

Is it better to take vitamins in the morning or at night?

Neil Levin, a clinical nutritionist at NOW Foods, agrees that morning is best for multivitamins and any B vitamins. “Multivitamins tend to do best when taken earlier in the day, as the B vitamins in them might stimulate metabolism and brain function too much for a relaxing evening or before bed,” Levin says.

Can taking a lot of vitamins make you nauseous?

That may sound like a way to help cover your nutritional bases, especially if your diet is less than stellar. But routinely getting an overload of vitamins and minerals can hurt you. Too much vitamin C or zinc could cause nausea, diarrhea, and stomach cramps.
