“B12 is really critical from head to toe.”

Vitamin B12, for example, supports cell health and also helps the body make new DNA. People who don’t get enough B12 may feel tired and weak and can experience a loss of appetite, weight loss, confusion, or nerve pain. Anywhere between 1.5% and 15% of Americans are deficient in B12. People older than 50 and those on vegan or vegetarian diets are at greatest risk, according to the National Institutes of Health. (Animal products are the only ones that naturally contain B12, although many breakfast cereals, “alternative” milks, and other food products are fortified with it.)

I write about health and science. I live in Detroit with my wife and kids. I’m trying to learn German, but my progress so far is nicht gut.
