Step-by-step explanation:
The category of micronutrients that is least likely to be harmful in high doses is vitamins.
Vitamins are organic compounds that are needed by the body in small amounts to function properly. They play many roles in good health and are involved in essential chemical reactions and processes.
While some vitamins are water-soluble and cannot be stored, others can be stored in the body's tissues and drawn upon when needed.
For example, vitamin C and most of the B vitamins are water-soluble and need to be consumed daily or every few days. On the other hand, fat-soluble vitamins like vitamins A, D, E, and K can be stored in the body and used when dietary intake is insufficient.
