Can dietary supplements be safe?

Yes: The body's biochemical processes need vitamins & minerals to work properly. Much of our grocery store food no longer contains the same levels of nutrients due to changes in farming. Environmental issues such as stress can cause a decrease in nutrients. Unless eating all organic food, supplements may be necessary and safe.

Depends: You have to know what youre taking. Many of them have interactions with medications. You can overdose on fat soluble vitamins a and d. Try to gather as much information and ask your health professional to review your supplements before taking them.
