Vitamin B6/Vitabin B 12 Injections?

I take B12 injections and have for 10 years now due to a medical problem causing me not to retain any B12 through stomach absorbtion. I have not experienced any weight loss in the 10 years only weight gain. While low/non-existant B12 levels can cause extreme exhaustion I wouldn't suggest taking the shots to try and lose weight when you can clearly do that on your own.

I too have to take B12 shots. again, I have not noticed any weight loss associated with them.Low energy without yes ( among other issues..lol) but just taking the shot doesnot cause me to lose wieght , thats why I'm on MFP in the first place

B12 does not affect weight but it is important for older women with anemia. It can also help some people with increasing their energy.

I have HypoThyroidism as well. I don't do shots but I absolutely take a B100 Complex (Timed Released) and 5000mg of B12. They both support oxygen flow in the blood which helps with the tiredness/exhaustion of the disorder. I also take A, C, D, E, Selenium and Zinc (that one is just to boost Immunity...nothing to do with Thyroid).

Try the B in pill form (you can do B12 Sublingual which is a quicker absorption) and see if it helps. I don't necessarily believe it helps with "weight loss" and I don't use them for that....but I sure believe it helps with my energy and overall better health.

Good luck!!!

If you're on meds for your thyroid you don't need additional supps to help with that. Have you checked your levels lately? Maybe you need a dose change. Also, look up vit B neurotoxicity.

I'm not a doctor, but here is what I know from my own issues dealing with what you're asking.
First, I too am hypothyroid. I'm also B12 deficient because my body won't store this, so I have to take injections. Guess what? Even when my labs came back at high normal levels of B12, I didn't feel any more energetic or focused and it certainly didn't boost any weight loss... especially the weight I'd gained from both my hypothyroid or my pregnancies. B vitamins do play an important role in our metabolism, so the doc is right to look there, but I'd suggest something else before paying for expensive injections (unless you give to yourself, which is much cheaper). I mentioned I have to have B12 injections because I'm deficient. Being deficient can cause irreversible neurological damage if not treated. Well, over a year ago, I started drinking something I buy at Costco (and Sam's club), called Zipfizz. It comes in various flavors and its a nutrient packed tube of powder you add to water and costs just under a buck a tube. Well, much to my doctors shock and mine, the B12 in Zipfizz made my levels of B12 shoot through the roof. Apparently, unlike other B12 supplements, this one is very much absorbable and bioavailable. In the 13yrs I've had to take shots, I've never had a lab come back with such a high count (1500). My body doesn't store B12, so this level was from drinking Zipfizz once a day and taking my shot once monthly. Where I'm going with this is, I'm still unfocused (Hello Hypothyroid symptom!!) and still struggle to lose weight (again, hello hypothyroidism symptom - has your doc checked TSH, T3 & T4 levels or just TSH, which isn't always correct) and yet, I have very high levels of B12. Zipfizz has both B6 and B12. Worth a try if he's suggesting those. I like the grape flavor, or the fruit punch you can buy online at costco.com (the actual website zipfizz.com is more expensive than Costco or Sams). Oh, but before you begin raising your levels, have that doctor check those levels - you might be on the low side and that would be worth finding out. Personally, I think Vitamin D and Omega 3's play a much more important role in helping one focus, and American's tend to be woefully deficient in both - especially Vitamin D (which sunblock isn't helping). Good luck!
