Does my body store vitamin B?

    B vitamins are not stored in your body. They are water-soluble vitamins, which means that after you consume them (from food or supplements), they travel around in your bloodstream and are used as needed. Whatever is left over is excreted in your urine. Vitamin C is another water-soluble vitamin.

    Fat-soluble vitamins ( A, D, E and K) are different: Whatever your body doesn't use right away is stored in the fat cells in your body for several weeks or months for future use.

    For more information about vitamins and your own vitamin needs, consult your doctor.

    Other than vitamin B12, your body has very limited ability to store the B vitamins so they must be replaced daily through food and/or supplements. B vitamins are water-soluble, allowing the body to excrete excess amounts or amounts not immediately used. The B vitamins include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (Pantothenic acid), B6 (pyridoxamine), B7 (biotin), folate, and B12 (cobalamin). Click on “dotFIT Supplements” in the Links section of the dotFIT profile page here  for information on B vitamin intake. The goal is to make sure you get proper daily amounts of all necessary B vitamins. This goal is accomplished by eating a healthy diet (as found in the Sharecare Fitness application) and taking a daily multivitamin and mineral formula that contains the necessary B vitamins within the amounts shown below (upper portion of range for active people and/or dieters unless otherwise noted):

    • B1: 2-10 mg/day
    • B2: 5-10 mg/day
    • B3 (Niacinamide – this form will not cause flushing): 15-30 mg/day
    • B5: 0-15 mgs (women and over 50)
    • B6: 6-12 mg/day
    • B7 (biotin): 100-300 mcg
    • Folic acid: 200-400 mcg/day
    • B12: 12-100 mcg
