Nature Made® B12 1000 mcg (400 ct.) is a convenient way to boost vitamin B12, an essential nutrient.

What Does Vitamin B12 Do?

Vitamin B12 keeps your nerve and blood cells healthy and helps to make DNA, or the genetic material found in all cells. In addition, vitamin B12 has been shown to help prevent megaloblastic anemia, a type of anemia that makes people tired and weak. Importantly, vitamin B12 plays a critical part in producing cellular energy, forming red blood cells and ensuring proper functioning of the nervous system.

Not everyone absorbs enough B12 from their food. For example, individuals who follow vegan or vegetarian diets may benefit from Nature Made B12 1000 mcg, since B12 is mostly found in animal products like chicken, milk, beef, eggs and fish.

What Are the Effects of a B12 Deficiency?

Those who don't get enough vitamin B12 may experience tiredness, constipation, weakness, loss of appetite, weight loss and megaloblastic anemia. Another effect of vitamin B12 deficiency is nerve problems, such as numbness and tingling in the hands and feet.

Other possible problems arising from vitamin B12 deficiency are issues with depression, balance, poor memory, confusion, dementia and soreness of the mouth or tongue. Infants who suffer from vitamin B12 deficiency may fail to thrive, have movement problems, experience developmental delays and develop megaloblastic anemia.

It's important to treat vitamin B12 deficiency with a Vitamin B12 supplement -- like Nature Made B12 1000 mcg -- as soon as possible, according to the National Institutes of Health.
