"Not good, after just two injections I have loss of urinating control, dizziness, feeling not in control. Just feeling peculiar. I have stopped the planned course after two injections..... Hoping the effects will pass . Interaction with other taken medications not expected."

"I lacked the intrinsic factor to absorb Vitamin B12 from food since I was in my 30s. I was diagnosed with breast cancer 2x and now am age 55 I increasingly find that I am dependent on the b12 for energy, mood and weight maintenance. I can tell when my levels are low without a calendar as this usually occurs about 3-5 days before the end of the month when I am do for my shot."

"I am 50 Initially I tried it to fight depression and low energy. Hoped it would help me trim off 10 lbs without the need for a diet. At first it helped, but after a few months I started gaining weight and developed muscle fatigue. I literally weakened by about 20% These injections began having a negative effect on me for everything I hoped they would help. I am not taking another one."

"I was on Vitamin B12 injections years ago and felt good, the thing is my workmates mentioned how I was different. I also have a thyroid problem and have started my injections again. I just didn't know why or what had me feeling so bad. I was diagnosed with BiPolar, but I wonder even with just B12 deficiency or thyroid alone, they have such a impact. But together I am very affected. Once I feel better I will see if I am BiPolar. The B12 injections do help, maybe not instantly, maybe days or longer, but they help 100%."

"I started injections about a two months ago. The first month was an injection once a week. Now I go once a month. The only thing I have noticed is a huge increase in back pain. I had to go to the emergency twice! No one told me I might have pain. But it makes sense, my nerves are waking up. Also I feel seriously bloated. Sometimes my jeans fit fine, sometimes they are tight. It's not vanity, I am fighting diabetes with diet and exercise, so the weight changes are disheartening. Other than the pain and bloat I don't really notice much difference."

"B12 is miraculous for me. I developed anemia from cancer treatment and went on B12 shots which gave me energy and resolved the anemia. I took the shots monthly for two years, I'm not on shots anymore. I take 1000 mg pill one per day."
