Can taking too many vitamins cause weight gain?

I started a high-dose multivitamin pack last month and I swear my weight has gone up by two kilos since then. Is anyone else experiencing this or is it just water weight? I am really worried that these tablets are messing with my metabolism.

Vitamins have zero calories, so they can't cause fat gain. If you are gaining weight, it's because of a surplus in your daily calorie intake, not your multivitamin pills. Track your daily food, keep up with your workouts, and don't stress about the vitamins.

Haan, this is actually a common doubt, but vitamins se weight gain nahi hota na. It's just that when your body finally gets the missing nutrients, you start feeling healthier and your appetite might open up a bit. Just keep eating healthy home-cooked meals and you'll be absolutely fine.

As a strict vegetarian, I monitor my B12 and D3 intake very closely. Vitamins don't contain fats or carbs, so they can't directly cause weight gain. However, correcting a vitamin deficiency often restores your metabolism and appetite, which might lead to eating more if you aren't careful with your food portions.
