What is B-12 Vitamin for?
Vitamin B12 is a vitamin. It can be found in foods such as meat, fish, and dairy products. It can also be made in a laboratory.
Vitamin B12 is used for treating and preventing vitamin B12 deficiency, a condition in which vitamin B12 levels in the blood are too low. It is also used to treat pernicious anemia, a serious type of anemia that is due to vitamin B12 deficiency and is found mostly in older people. For this purpose, people use either a supplement that is taken by mouth or a gel that is applied inside the nose.
Vitamin B12 is also used for memory loss; Alzheimer’s disease; boosting mood, energy, concentration and the immune system; and slowing aging. It is also used for heart disease, lowering high homocysteine levels (which may contribute to heart disease), male infertility, diabetes, sleep disorders, depression, mental disorders, weak bones (osteoporosis), swollen tendons, AIDS, inflammatory bowel disease, asthma, allergies, a skin disease called vitiligo, preventing cervical and other cancers, and skin infections.
Some people use vitamin B12 for amyotrophic lateral sclerosis (Lou Gehrig’s disease), multiple sclerosis, preventing the eye disease age-related macular degeneration (AMD), Lyme disease and gum disease. It is also used for ringing in the ears, bleeding, liver and kidney disease, and for protection against the poisons and allergens in tobacco smoke.
Vitamin B12 is applied to the skin either alone or in combination with avocado oil for psoriasis and eczema.
Vitamin B12 is frequently used in combination with other B vitamins in various vitamin B complex products.
What is B-12 Vitamin Possibly Effective for?
• Treatment and prevention of vitamin B12 deficiency, and diseases caused by low vitamin B12 levels.
• Treatment of pernicious anemia.
• Shaky-leg syndrome. There are some reports that one form of vitamin B12 (cyanocobalamin) can help relieve tremor due to shaky-leg syndrome.
• Eczema (atopic dermatitis). Limited research shows that applying a specific vitamin B12 0.07% cream (Regividerm) to the affected area twice daily reduces the extent and severity of eczema.
• Alzheimer’s disease. Limited research suggests that higher vitamin B12 intake does not seem to prevent Alzheimer’s disease.
• Cervical cancer. Increasing vitamin B12 intake from food and supplements, along with taking folic acid, thiamine, and riboflavin, might help to prevent cervical cancer.
• Breast cancer. There is no evidence that dietary vitamin B12 alone reduces the risk of breast cancer.
• Lung cancer. Preliminary evidence suggests that there is no relationship between levels of vitamin B12 in the blood and lung cancer.
• Chronic fatigue syndrome (CFS).
• Preventing re-blockage of blood vessels after heart artery dilation (balloon angioplasty).
• Fatigue or tiredness.
• Heart disease.
• Lyme disease.
