Know Your A, B, Cs: Vitamin B (How Many Are There?)


There are eight B Vitamins to be exact, and they help maintain healthy skin and muscle tone, enhance your immune and nervous system functions, and promote cell growth and division.

They are water-soluble vitamins which means that your body can't store them. They need to be replenished daily because whatever the body doesn't use, gets flushed out in your urine.

The eight B vitamins are B1, B2, B3, B5, B6, B7, B9, and B12 - and they all have other names that you're probably more familiar with.

Most people get these vitamins in the food they eat. If you have food restrictions, whether you don't eat meat, dairy products, eggs, or whole grains for whatever reason, you may need to take supplements. When a supplement has all 8 of these B vitamins, it's referred to as vitamin B complex. If you buy separate B vitamins, then they are referred to by their specific name (B1, B12, etc.)

Allow me to explain each one...
