Several major findings were as follows:
1. The most frequently used dietary supplements was calcium tablet（57.8％）.
2. Peceived benefits and family support had a positive relation to the intake of dietary supplements.Peceived barriers had a negative relation to the intake of dietary supplements.

As the result of this study, I suggest teachers should teach their students how to have the correct concepts in using dietary supplements. Besides, the government should oversee the products. Under the superintendence of the government, parents can have a safe environment to choose their proper dietary supplements. In the future study, I hope there might be a deeper investigation for the parents in using dietary supplements.
