While working in the wellness industry, Keith Marz regularly met patients who were struggling to lose weight because they were afraid to swallow vitamin pills as directed. In turn, Marz researched alternative methods for delivering the nutrients. He ultimately discovered that sprays were not only easier to swallow but easier for the body to absorb, since they were already liquid.

Today, his Marz Sprays serve multiple purposes: The C Spray is a multivitamin and immunity blend of 200 mg of vitamin C, the Slim Spray has a medley of vitamins that burn fat and reduce food cravings, and the Reboot Spray has 2,500 mcg of vitamin B12 in case your internal computer freezes. Only a few sprays are needed per use, so each bottle typically lasts about 30 - 60 days. The sprays are sugar- and calorie-free.

Given the products’ longevity and use of quality-sourced ingredients, Marz has received a lot of press and even successfully pitched the idea on the television show Shark Tank.
