B1 helps the body make healthy new cells. It’s often called an anti-stress vitamin because of its ability to protect the immune system. When carbo-loading (either to prepare for a big race or just because pizza tastes that good), studies say this vitamin is necessary to help break down those simple carbohydrates.
Along with fellow B vitamins 12 and 9, B6 helps regulate levels of the amino acid homocysteine (associated with heart disease). Pyridoxine is a major player in mood and sleep patterns because it helps the body produce serotonin, melatonin and norepinephrine, a stress hormone. Some studies suggest vitamin B6 can reduce inflammation for people with conditions like rheumatioid arthritis.
This B vitamin is a total team player. Cobalamin works with vitamin B9 to produce red blood cells and help iron do its job: create the oxygen carrying protein, hemogloblin. Since vitamin B12 is only found in animal products, studies show higher rates of non-meat eaters with a deficiency. “But unless you are a strict vegan or vegetarian,” Zuckerbrot says, “it’s not hard to get enough of this vitamin in your diet.” For those who are deficient, it may be necessary to supplement the diet with B12.
