  • Q: Some of the ingredient levels are more than the Nutrient Reference Value (NRV), why is this? A:

    Centrum products are classed as food supplements and are designed to complement a person’s diet.
    Having more than 100% of the NRV should not cause any concern, because the levels are safe and do not exceed the recommended Safe Upper Level (SUL) for each vitamin.
    Water soluble vitamins - such as the B group vitamins and vitamin C - cannot be stored by the body to any great extent, so if you take in more than your body needs, they are simply excreted.
