Sean Riggins, a Lincoln high school athlete in his prime, died after taking a legal nutritional supplement in 2002.

His family has worked diligently since then to prevent other people from suffering the same tragedy.

Their efforts have resulted in more regulation of dietary supplements and a greater awareness of their risks.

People need to know what they are taking, be well-informed, talk to their doctors and take as these substances directed. That's the key lesson.

The federal regulator system does not treat supplements as medicinal drugs.

Treating nutritional supplements different than drugs enables people to gain easier, quicker access to these products, many of which have been used in other countries for years.

But it also puts additional responsibility on users of the products.

Although they are not classified as drugs, the supplements can react in the body similar to drugs. And they can interact with medications. That's another reason why it is wise to let your doctor know if you take a dietary supplement.

These dietary supplements should be treated with respect and caution - just as over-the-counter medicines and prescription-only drugs need to be respected and used properly.

Earlier this month, the Food and Drug Administration called for tougher, more visible warnings on acetaminophen, aspirin, ibuprofen and other nonsteroidal anti-inflamatory medicine. In particular, the FDA warned of the risks of overdoses.

"More is better" is a dangerous approach, whether your are taking medicine or dietary supplements - or talking about government regulation.
