My doctor hinted that some diabetes medications can affect Vitamin B12 levels. I'm wondering if I should take a B12 supplement. Can diabetics take B12 supplements, and what's the right way to go about it?

Beta, I have been taking Metformin for my diabetes for 15 years, and my doctor told me it can cause B12 deficiency over time. I take a B12 supplement regularly on his advice and feel much more energetic. Don't worry, it is very common and safe.

Hey bro, don't stress too much about B12! It's actually super helpful, especially if you are on diabetic meds which can lower your B12 levels. Just get a quick green light from your doc and start taking it.

Haan babu, B12 bilkul le sakte hain. Humare bade-buzurg bhi kehte hain ki sharir mein taqat ke liye ye zaroori hai. Bas doctor sahab se ek baar pooch lijiye ki kaunsi goli khani hai.

I totally get it, managing diabetes along with worrying about other deficiencies is so exhausting. B12 is generally very safe and often recommended for diabetics, but please do check with your doctor once to get the right brand and dose.

Please get a proper blood test done before starting any supplement. I had severe nerve tingling which I thought was just general weakness, but it was a complication of both B12 deficiency and high sugar. Your doctor needs to decide the exact dosage.

My mom is diabetic and her doctor recently put her on a B12 supplement because her levels were really low. It has really helped with her daily fatigue. It is definitely worth discussing at your next checkup!

I was so worried when my doctor suggested B12, thinking it might spike my sugar! But after reading up, I realized it is actually very important for nerve health in diabetics. Don't worry, just verify the dose with your doc to be absolutely safe.

B12 tests and supplements can add to your monthly medical bill, but they are worth it. Ask your doctor for a generic option as those are much cheaper than branded ones. Try to plan your blood tests together to save lab visit charges.

Hey, my dad is diabetic and he takes B12 tablets daily because his doctor told him metformin can reduce B12 absorption. It's super common, so you should be totally fine.

Do not start taking B12 supplements blindly based on internet suggestions. Get your serum B12 levels tested first. If there is a deficiency, your doctor will prescribe the correct therapeutic dose rather than you self-diagnosing.

I have thyroid issues along with borderline sugar, and both conditions require keeping an eye on vitamins. Definitely get your B12 and Vitamin D tested regularly during your routine doctor follow-ups to keep your energy levels up.

Please go get your levels checked. I ignored my constant leg numbness for months, thinking it was just diabetes, but it turned out to be a severe B12 deficiency. A simple doctor-prescribed supplement fixed it, so don't delay your checkup.
