8 Water-Soluble Vitamins and Where to Find Them

The water-soluble vitamins are vital for many of the functions your body needs to stay healthy, including energy production and immune system function.

Your body doesn't store most of the water-soluble vitamins very long, so they need to be replenished daily. Take a tour through the water-soluble vitamins, where to find them, and their benefits.

Folate is found in leafy green vegetables, oranges and strawberries, legumes and whole grains. Your body needs folate to make red blood cells and to break down the proteins you eat. Folic acid is the form of folate found in supplements.


Vitamin B12

Vitamin B12 is found in meats, poultry, seafood, eggs, and dairy products, but not in plant-based foods so vegans are at risk for vitamin B12 deficiency. You need vitamin B12 for a healthy nervous system and blood cell production.
