Brent is a 22-year-old man who doesn't smoke. His RDA for vitamin C is 90 mg per day.

If he takes mg of vitamin C each day, he will consume megadose amounts of the vitamin. (Check all that apply.)

a.1000

b.100

c.200

d.50

e.900

a and e are correct

Explanation:

Data provided in the question:

Daily recommended intake of Vitamin C for Brent = 90 mg/day.

Now,

The upper limit for the intake of Vitamin C as recommended = 2000 mg/day.

Therefore,

If Brent is consuming 900 and 1000 mg of vitamin C per day, the Brent is

consuming megadose amounts of vitamin.

Hence,

900 mg and 1000 mg represent almost 9-10 times extra intake of

vitamin C. i.e a and e are correct
