You can try your question in Weight Loss Alternative, but I, personally, would advise you to save your money. I take vitamin B12 shots because I have a deficiency and I can guarantee they haven't helped me to lose an ounce.
If you lack energy, Vitamin B12 might help increase your energy levels in order for you to be able to exercise more.
I'm with Ranae, we'd like to see you stick around and lose weight using a reasonable diet/exercise program, so you would be better able to keep off any weight you might lose.
Goot luck,
Thank you for joining MedHelp and for asking your question regard B-12 injections. The WL&D community members work together and support each other in losing weight by focusing on nutritional and balanced food choices via a variety of plans, implementing moderate and regular exercise and changing our behavior and ways of thinking about our relationship with food. Perhaps you will consider joining us in this endeavor and, in exchange, the members here will offer their assistance, share their knowledge, give their support and encouragement and make every attempt to keep you motivated and engaged in the process. The weight, exercise and mood trackers are most helpful and highly recommended.
If you would rather continue looking for B-12 injections as a way to lose weight, your question may be better served in the Weight Loss Alternative community. If you would like your post moved there, please let me know and I will do so.
Hoping you will consider joining the community as an active and regarded member. Very best wishes ...
