Phiten

Instructors at the United States Air Force Academy conducted a double-blind study of the Phiten claim. Initially the instructors became interested in this product because of the company's claims that it could cause relaxation, maximize strength and energy. When looking into the product before testing they flagged several concerns; Most studies supporting Phiten were also funded by Phiten. The claims sound like the definition of pseudoscience with no mechanism to show how it could work and the claims are unfalsifiable. The packaging claims that '"not all users will experience the intended benefits."' Leaving the user to believe that it will work or it will not work. Also the instructors felt that the Phiten product was similar to other pseudoscientific medical accessories like copper bracelets, crystals and magnetic bands.

Forty-eight Academy cadets wore a tape-covered necklace for 48-hours, half were necklaces purchased from the Phiten website and the other half were clothesline purchased from The Home Depot. All necklaces were the same length and wrapped in masking tape. The cadets selected a necklace from a bin and they and the instructors did not know who wore a clothesline and who wore a Phiten necklace. At the end of the 48-hours each cadet was asked to fill out a survey rating from one to nine, if they felt relaxed, angry or energized? The conclusion was that there was no "statistically significant difference" between the clothesline and the Phiten necklace.

Furthermore, the instructors procured soil samples from a baseball field and analyzed the results checking for titanium. They also asked the Phiten company what the weight percent of titanium is in their necklaces, but were told it is a "corporate secret". The academy instructors learned that titanium was plentiful in the soil samples, and also learned that titanium is "the ninth most-abundant element on the planet". This led the instructors to state that baseball players "are purchasing Phiten necklaces to receive the purported benefits... when they are routinely performing... on playing fields that contain titanium."
