Outcomes from associated literature, summarized in Desk 2, confirmed that each day consumption of those nutritional vitamins in some circumstances not solely had no profit but additionally elevated the chance of illness. With concern to outcomes of those research, there’s a major query; ought to we give up taking these nutritional vitamins or ought to we use them correctly and simply with doctor order or pharmacists consults?

As a result of limitless entry of individuals to nutritional vitamins and in addition lack of affected person’s consideration into multivitamins elements and their doses, it could be excessive possible {that a} affected person use nutritional vitamins in increased doses. It may be prompt that vitamin administration ought to be below the management of well being supplier professionals like pharmacists and solely be marketed by pharmacies to be able to present crucial data for sufferers about acceptable nutritional vitamins use. As well as, labeling of nutritional vitamins ought to embrace data on beneficial higher consumption, protected dosing and doable toxicities.
