As women sometimes we count on one another for health tips, especially as age changes the way our body uses and produces energy. One thing you may have gone to your mother or best girl friend to find out is which vitamins you need to take. There’s plenty of variety in the supplement department. One general vitamin that we can’t get enough of is vitamin B12. It keeps your nerves and red blood cells healthy for the most part, and critical in many body processes. The older you get, the harder it can be to absorb vitamin B12 in the body. Strict vegetarians, drinkers, smokers, pregnant women, and the elderly are usually at high risk for B12 deficiency. Sure, you can take a daily supplement, but this is one complex vitamin that can be found in food sources you use every day. A few benefits of vitamin B12 include more energy throughout the day, less stress on the nervous system, and healthier skin, hair, and nails.
