Taking vitamin B12 injections may sound weird, but this is because most people are not familiar with vitamin B12 and how it works.
B12 is certainly not as popular as vitamins C and D, and its use to the human body is still being studied, although scientists now know the important function it has on keeping our brains, nervous systems, and red blood cells in good condition.
Why take Vitamin B12 Injections?
Vitamin B12 injections are given for people with vitamin B12 deficiency, Alzheimer’s disease, anemia, anorexia nervosa, chronic fatigue, memory loss, obesity, heart disease, depression, osteoporosis, AIDS, diabetes, and sleep disorders.
The effect of B12 on weight loss is still undergoing research, although most doctors agree that it’s better to take oral supplements of B12 rather than injections for those who are going on a diet. This will help make sure they get all the B12 their body needs. In several cases, pills and capsules of B12 are prescribed before injections are considered, and this is because of the possible vitamin B12 side effects.
Taking vitamin B12 through injection form means your body gets more of the nutrient immediately since injection doses are far higher than those that come in oral supplement form.
Common side effects of B12 injections
The side effects are usually not serious, such as upset stomach, a mild case of diarrhea, nausea, trouble sleeping, headache, heartburn, joint pains, skin itchiness, stuffy nose, and muscle pains.
Tenderness and swelling at the injected site also occurs a lot. Most people who take B12 injections will not actually experience side effects, especially if they go for very light doses, such as using B12 for insomnia remedies.
Possible serious side effects of taking B12
However, this doesn’t mean vitamin B12 injections cannot give serious side effects, some of which can be fatal, such as thrombi or blood clots, heart failure, and pulmonary edema, which is liquid gathering in the lungs.
The connection between B12 and these dangerous reactions lies in the wide range of the vitamin’s uses to the human body, and since B12 injections are essentially synthetic and not natural like what you get from meat and dairy products the body can react negatively and even fatally with them.
This is why any sort of sensation or changes noticed after taking B12 injections are best reported to the doctor as soon as possible. Vitamin B12 injections should only be taken with a licensed and experienced doctor’s approval.
