Can vitamin d3 cause weight gain?

My doctor recommended vitamin D3 for my low levels, but I'm trying to lose some weight, actually. Will taking D3 supplements make me gain weight? I'm a bit hesitant to start them if that's a side effect.

I used to worry about this too and tried all sorts of herbal teas thinking my weight gain was from my vitamins. But actually, Vitamin D3 doesn't have any calories and won't make you put on weight. Just focus on eating clean home-cooked food and consult your doctor if you still feel heavy.

When I was prescribed high-dose D3, I asked my doctor at Apollo Hospital if it would cause weight gain. She clearly told me that D3 actually helps with metabolic health and shouldn't cause weight gain at all. You should ask your doctor clearly to find the real reason behind your weight changes.

My teenage daughter had to take weekly Vitamin D3 supplements because her levels were extremely low, and we were also worried about weight changes. Thankfully, she didn't gain any weight; in fact, her energy levels improved so much that she became more active. Please don't worry and follow your doctor's advice.

I was researching this on medical portals recently because I also started taking D3 supplements. Most studies actually show that correcting a Vitamin D3 deficiency can help with weight management rather than causing weight gain. It is definitely safe to take as long as your doctor prescribed it.

I wish I could blame my extra belly fat on my tiny Vitamin D3 capsules! But sadly, science says D3 doesn't cause weight gain. It's probably my love for parathas and lack of sleep doing the trick, so let's get our facts checked by a doctor first.

I agree with the points here, D3 doesn't cause weight gain. Get a proper thyroid and hormonal panel done to check for other issues.

No, Vitamin D3 does not cause weight gain, period. If you are gaining weight, it is likely due to a poor diet, lack of exercise, or some other underlying hormonal issue. Stop guessing and go see a doctor to get a proper checkup.

I completely understand how stressful it is when you notice your weight creeping up and start suspecting your daily supplements. But please be reassured that Vitamin D3 is highly unlikely to cause weight gain. Take a deep breath and visit your doctor to find out what else might be causing this.
