Does biotin cause weight gain?

I've started taking biotin supplements for my nails and hair. My cousin said that biotin can sometimes cause weight gain. Is this true, or is it just a myth?

I started a high-dose biotin supplement two weeks ago and I feel like my face looks a bit bloated lately. Has anyone else noticed water retention or weight changes after starting this? I am really hoping it's just in my head because I really need it for my hair.

I've been taking biotin gummies for my hair fall during exams and honestly, I haven't gained any weight at all. If anything, my metabolism feels slightly better. Don't worry, those tiny gummies aren't going to ruin your fitness goals!

While biotin is just a B-vitamin that shouldn't cause weight gain, everyone's body chemistry is different. If you are noticing sudden weight changes, it is always safer to get your thyroid and hormone levels checked by a doctor. Don't just ignore sudden physical changes.

Actually, biotin helps your body process carbs and fats better, so it might even help your energy levels! I've been taking it for months and my weight is completely stable. Plus, my nails look so pretty now!

Weight gain happens when we eat more paranthas and sit all day, not from a tiny vitamin tablet. If you are worried, just do a brisk 30-minute walk daily and avoid sugary snacks. Biotin is just a vitamin, it won't make you fat on its own.

Don't stress too much about it, sweetie! Biotin is just a vitamin and it doesn't have any calories that can make you gain weight. Just enjoy your healthy hair journey and don't let these online worries ruin your peace.

I take various supplements along with my BP meds and none of them have caused weight gain. Weight is managed by lifestyle, low salt, and regular physical activity. Biotin is water-soluble, so any excess is just removed by the body naturally.

With gentle yoga and mindful breathing, our body naturally maintains its ideal weight. Biotin is just a supportive nutrient for our hair and nails. It does not cause weight gain if you keep your lifestyle natural and your mind calm.

Hey! I had the same worry before starting biotin for my dry hair. My doctor told me it actually supports metabolism, so weight gain is highly unlikely. Just watch out for some hair gummies that have added sugar, as those extra calories can add up!

No way bro, biotin doesn't make you gain weight. I use it for my beard growth and my weight has been exactly the same. Just keep hitting the gym and eating clean, you'll be fine.
