Question

best describes nutritional supplements?
supplements are regulated by the fda like drugs; they are approved before being available for sale.
supplements are not regulated; they can be sold without any approval or proof of effectiveness.
supplements are regulated, but the regulation companies have a history of making mistakes.

Explanation:

To determine the best description of nutritional supplements, we analyze each option:

• The first option claims supplements are regulated by the FDA like drugs (requiring approval before sale). However, nutritional supplements are not regulated like drugs by the FDA; drugs need FDA approval before marketing, but supplements do not. So this is incorrect.
• The second option states supplements are not regulated and can be sold without approval or proof of effectiveness. In the US, nutritional supplements are regulated under the Dietary Supplement Health and Education Act (DSHEA), so they are regulated (though differently from drugs). Thus, this is incorrect.
• The third option says supplements are regulated, but the regulation (DSHEA) is less strict than drug regulation, and companies have made mistakes (e.g., mislabeling, making unsubstantiated claims). This aligns with the regulatory status of supplements: they are regulated, but the regulations allow companies some leeway, and there have been instances of non - compliance or mistakes.

Answer:

The third option (Supplements are regulated, but the regulation companies have a history of making mistakes)
