  1. Vitamins are important to proper body building and repair, but be aware that you can overdose and harm yourself.
  2. Fat-soluble vitamins are stored in the body's fat reserves, so be careful not to take too much vitamins A, D, E, and K.
  3. Water-soluble vitamins are not stored in the body like fat-soluble ones, so it's less likely to overdose on vitamin C and the B complex.
  4. I realize vitamin supplements are a factor in your training, but be aware of daily requirements so you don't overdose, especially the fat-soluble vitamins.

Answer to Question 1

ANS: 4
The fat-soluble vitamins (A, D, E, and K) are stored in the fatty compartments of the body. Hy-pervitaminosis of fat-soluble vitamins results from megadoses (intentional or unintentional) of supplemental vitamins, excessive amounts in fortified food, and large intake of fish oils. The wa-ter-soluble vitamins, vitamin C and the B complex (which is eight vitamins), are not stored, so these need to be provided in the daily food intake. Although water-soluble vitamins are not stored, toxicity can still occur. The remaining option is not incorrect but is not as inclusive as the answer.

Answer to Question 2

ANS: 4
Certain vitamins are currently of interest in their role as antioxidants. These vitamins neutralize substances called free radicals, which produce oxidative damage to body cells and tissues. Re-searchers believe that oxidative damage increases a person's risk for various cancers. These vita-mins include beta-carotene and vitamins A, C, and E. The remaining options oversimplify the re-sponse or give very unspecific information.
