With the wellness industry worth nearly $4 trillion , its no surprise that many people are trying to jump on board.

But for every trend or product that actually helps us get healthier, there are hundreds that are simply a flash-in-the-pan fad. Some may just put a big dent in your bank account with no reward, while others may actually harm you. Below, we reminisce about the most ridiculous trends that caught our eye this year and figure out whether any of them hold (good, old-fashioned, plain) water.

While it is somewhat controversial, the treatment is approved by the Food and Drug Administration and generally safe, according to experts .
