Does taking b12 help with weight loss?

My B12 levels were a bit low according to my recent blood test, and I often feel sluggish. I'm also trying to lose some weight. I heard B12 can boost metabolism; does taking B12 help with weight loss?

I was looking this up because my B12 was low. It seems B12 is essential for energy metabolism, but taking extra supplements won't cause weight loss unless you were actually deficient.

When I consulted the physician at Fortis, they said B12 only boosts energy levels if you have a deficiency. It is best to ask your doctor for a blood test before starting any supplements for weight loss.

I wish B12 could melt away all the biryani I eat! Sadly, it only helps with your energy levels, so you still have to watch what you eat to lose weight.

No, B12 does not directly cause weight loss unless you had a severe deficiency that was causing extreme fatigue.

I used to panic that my slow metabolism was due to some vitamin deficiency. It turned out my B12 was low, and correcting it gave me the energy to finally exercise regularly, which helped with weight loss.
