Penta Water undergoes a patented process which the company claims to result in specific health benefits.

[3][6] In response to the lawsuit, the makers of Penta said that scientists from UC San Diego as well as the Scripps Research Institute[6] "had confirmed the health benefits of their water".

[3] In March 2005 a public complaint was filed with the Advertising Standards Authority in the United Kingdom regarding a promotional leaflet on the qualities of Penta Water.

They submitted research papers that they believed showed scientific evidence of restructuring and several works in preparation, including studies from UK universities, that they believed showed increased performance and recovery levels after exercise with Penta when compared with ordinary water.

The advertisers argued that, because Penta could hydrate more efficiently than tap water, it was better for health; they said they had not, however, made any medicinal claims for the product.

[8][7] Thus, the ASA "told the advertisers not to repeat claims that implied the product was chemically unique, had been restructured or molecularly redesigned, or hydrated cells and improved physical performance better than tap water.
