If you are constantly drained, you run out of energy, bloated and emotionally weak, do a blood test to check the level of vitamin B12 in your body. Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a key role in the normal functioning of the brain and nervous system. Since it is only available in animal-based foods, deficiency is common among vegetarians. Those of us with anemia are also prone to vitamin B12 deficiency, as many of us who are dieting who ignore micronutrients.
Importance of vitamin B12
Supports energy: Vitamin B12 keeps our cells healthy and agile because it converts carbohydrates into glucose in the body, thus leading to energy production.
Protects the heart: It eliminates a dangerous protein called homocysteine from the blood. Homocysteines damage the arteries, leading to inflammation and heart disease. Vitamin B12 also controls and improves unhealthy cholesterol levels, protects against strokes and controls blood pressure.
Our bones need it: Studies suggest that patients with osteoporosis have higher homocysteine levels and lower vitamin B12 than people with strong, healthy bones.
Improves mood: Vitamin B12 is a cofactor in the synthesis of mood hormones, serotonin and dopamine.
Protects brain health: The researchers found that patients with Alzheimer's disease had lower B12 levels than patients of the same age who had sharp and clear memory.
We keep young: Vitamin B12 helps cell reproduction and constant renewal of the skin.
Prevents cancer: Vitamin B12 helps protect against cancers of the breast, colon, lung and prostate.
Helps you think: A deficiency can limit your ability to think clearly.
Food sources
Vitamin B12 is found only in foods of animal origin such as eggs, chicken, seafood and dairy products such as milk, cheese (paneer) and yogurt. It has been shown that Swiss cheese has the highest content of vitamin B12.
Synthetic forms include multivitamins, B-complex vitamins and supplements. In its sublingual form, this vitamin is absorbed rapidly. It should only be injected under medical supervision.
