Stress Killer, a supplement powder, debuted at Natural Products Expo West in 2017. The Reston, Virginia, company's first product was Soldier Fuel energy bars, which Christian D’Andrea and his brothers created after learning that soldiers were being supplied bars that were loaded with trans fat, according to the Washington Business Journal. While the brothers researched nutritional information for Soldier Fuel, they learned how nutrition affects stress--information that led to making Stress Killer. The Stress Killer website states, "Our goal is to help you fight [stress], so that you can be more productive, more focused, and more calm." D’Andrea also is an author and a documentary producer. He graduated from Harvard University with bachelor's degrees in history and literature, and earned master's degrees in the same subjects from Oxford University, England, according to his LinkedIn page.
