Let's Get To the Root of It

The Earth's oldest living thing is an ancient bristlecone pine referred to as "Methuselah." The tree is nearly 5,000 years old [source: PBS]. That's 1,000 years older than any other tree in history. The age of the tree was determined using the common tree-ring method.

Side Effects of Anti-aging Supplements

There are two sides to every story, and anti-aging supplements are no exception. Before you start taking any, you should know the possible side effects. It's important to understand that dietary supplements aren't as strictly regulated as medications, and as a result, they may not be exactly what they say they are. An impure product is likely to cause side effects that wouldn't normally be associated with a supplement in its pure form [source: Monson & Schoenstadt].

Even when it comes to a supplement like coenzyme Q10, which already exists in our bodies, there are possible side effects. These include dizziness, fainting, allergic reactions, nausea, diarrhea and a few gastrointestinal conditions [source: Monson & Schoenstadt]. Even aspirin can cause a slew of side effects. While heartburn, nausea and an upset stomach are rather common, aspirin can also cause severe allergic reactions, bloody stools, dizziness, vomiting -- the list goes on [source: Drugs].

The miracle supplement HGH may give great results, but at what cost? This growth hormone was originally used as a short-term treatment and not meant for continual long-term use. Side effects can include high blood pressure, joint pain and in some cases, facial bone growth. On top of that, it can lead to an irregular heart rhythm, a higher risk of diabetes and carpal tunnel syndrome [source: Kuczynski].

The bottom line is that any product claiming to be an anti-aging supplement is probably too good to be true. More studies need to be done to confirm the benefits of most supplements that are on the market. As always, you should check with a doctor before taking any kind of supplement or medication.
