Question

select the correct answer.
jade heard that vitamin k can strengthen her bones so she started taking megadoses of it daily. what negative effect could this have?
a. get her banned from sports tournaments
b. lower her ability to absorb vitamins c and e
c. poison her by building up too much vitamin k in her body
d. cause hair loss and a severe case of acne

Explanation:

To solve this, we analyze each option:

• Option A: Vitamin K isn't a banned substance in sports like some performance - enhancing drugs, so this is incorrect.
• Option B: Vitamin K doesn't interfere with the absorption of vitamins C and E. So this option is wrong.
• Option C: Vitamin K is a fat - soluble vitamin. When taken in excess, fat - soluble vitamins can accumulate in the body (in fat tissues and the liver) and reach toxic levels. So taking megadoses of vitamin K can poison the body by building up too much of it. This option is correct.
• Option D: Hair loss and severe acne are more associated with excess of some other vitamins (like vitamin A in some cases) or hormonal imbalances, not vitamin K. So this option is incorrect.

Answer:

C. poison her by building up too much vitamin K in her body
