Final answer:
Water-soluble vitamins need to be consumed daily as they are not stored in the body.
Step-by-step explanation:
The group of vitamins that must be supplied in the diet every day since they are not stored in the body are the water-soluble vitamins. Water-soluble vitamins include B vitamins (such as B1, B2, B3, B6, B12), vitamin C, and folic acid. These vitamins are easily dissolved in water and are not stored in the body for long periods of time, so they need to be consumed regularly through food sources or supplements to meet the body's requirements.
