Supplementation is not necessary unless dietary intake is low.

There is no benefit of taking a lot of Vitamin C but since Vitamin C is a water soluble which means any excess that your body doesn't need will be excreted in urine. Supplements like Berocca contain B vitamins, magnesium but also Vitamin C. Since vitamin B and C are water soluble vitamins, whatever our body doesn’t store or use, the excess is excreted through our urine, why is why some multivitamins or supplements like Berocca can leave our urine looking a bright shade of yellow.
