Can vitamin b 12 cause weight gain?

I recently started taking Vitamin B12 supplements for energy. However, I've also noticed a slight increase in my weight. Can Vitamin B12 cause weight gain, or is this just a coincidence?

I was prescribed B12 injections last year because my levels were extremely low. Personally, I didn't experience any weight gain at all, but my fatigue improved so much that I could finally start exercising regularly. It really varies from person to person.

I literally check my weight every morning and get so anxious about new supplements! Honestly, B12 itself doesn't cause weight gain, but if you were deficient, it might improve your appetite and energy levels. Just keep an eye on your overall diet and you'll be fine.

There is no need to worry about weight gain from basic vitamins. Just eat balanced meals and do some walking daily. If your B12 is low, take the supplements as advised by your doctor to keep your nerves healthy.

Honestly, I wish B12 was the reason for my weight gain and not my late-night snack ordering! It doesn't actually cause weight gain, it just helps your metabolism function properly. Go ahead and take it if your doc prescribed it.

Haan yaar, B12 se weight gain nahi hota hai na. It actually improves your energy, so you might feel more active. Faltu me tension mat lo aur doctor ki advice follow karo.
