Cyanocobalamin "The second lot of injections I had set my anxiety off so bad I had insomnia from not being able to sleep, and this time it's making me feel anxious and making my heart beat so fast. So, not sure I should continue with it."

Cyanocobalamin "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 at 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 due for my shot."

Cyanocobalamin "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."

Cyanocobalamin "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."

Cyanocobalamin "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 an 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%."

Cyanocobalamin "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 a 1000 mg pill, one per day."

Cyanocobalamin "I started injections about 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."

Cyanocobalamin "My diet is mainly vegetarian, fish, and chicken, hence, I have a vitamin B12 deficiency. However, I have high energy levels. I have recently started vitamin B12 injections. After the second injection, symptoms commenced, which I don’t suffer from normally: high anxiety, racing heart, high blood pressure, diarrhea, nausea, vomiting. I went back to my holistic doctor, and we decided to stop the injections and take only the sublingual and vitamin B tablets at breakfast time. We will try injections every few months."

"Holy shit!! I had B12 deficiency for around 10 years (suspected timeframe) without getting treatment, and holy moly, the treatment has honest to God changed my whole view of life. Compared to 2 months ago when I started treatment to now, I don't even like the same things anymore, and I am EXTREMELY more social and happier socially than I was before. Deficiency caused me to be in a constant 'sleeping drowsy' state, and all I wanted to do was sleep and watch movies and dream away. It was a strange lifestyle. I tried to become more active, but every attempt just failed. If I tried to work without having slept at least 2 times in one day (yeah!), I would be a completely nonfunctioning vegetable. Now? I go to work with 3 hours' sleep and pound through the whole day no problem. 4 weeks of pills made such a dramatic difference, I would urge anyone that suspects it to go and get tested."

"I have been eating a plant-based, whole food diet (vegan) for the last year and taking this form of B12 every day. I take 1000 mcg twice daily, and this has not helped at all. I have become more and more tired and just don't have energy to do the normal activities of daily living. I have been researching and found many people cannot utilize this form of cobalamin and have taken methylcobalamin with great success. I took my first dose tonight and will report back. There was even a doctor who reported that in his practice he found the above information to be true with respect to oral supplementation. He did say that injections of cyanocobalamin worked, but the oral form failed. Sublingual methylcobalamin did work with his patients."

Cyanocobalamin "I couldn't be happier with CaloMist. I've been using it now for about 4 months, and I would recommend it to anyone who is taking any form of B12. I used to get B12 injections, but not anymore."

Cyanocobalamin "No aftertaste, unlike all the others that I have tried -- and it does not cause awful-tasting gas, unlike all the others that I have tried. Smaller than most of the others too!"
