— Move over M&M's. Nudge to the side Nutella. Astronauts now have a new type of chocolate to savor on — and super charge — their flights to the moon.

Astreas, a performance nutrition company, has revealed that its chocolate truffles were eaten on board NASA's Artemis II mission as crew members Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen became he first people to fly by the moon in more than 50 years. Although the spherical treats did not float across the camera at a key moment of the flight — just like a certain cocoa and hazelnut-sweetened spread did — the Astreas truffles made history as the first performance chocolate to be flown on a journey to the moon.

"To say this product is stellar is an understatement," Scott Parazynski, a former NASA astronaut and chief medical officer of Astreas, said in a statement. "It has now been experienced across multiple spaceflight environments, culminating with the Artemis II mission. We are honored to have it accompany these pioneering explorers."

According to the Astreas website, the truffles were designed as a reimagined energy chocolate, pairing 70 percent Valrhona dark chocolate with coffee beans and algae oil to deliver a boost of energy and focus. The individually-wrapped chocolates are each 100 calories and have just 3 grams of added sugar.

Each sphere is blended with Citicoline (Cognizin), L-theanine and caffeine.

As for their taste, Astreas describes the truffles as having a "bold, bitter-sweet dark chocolate profile with a smooth, sophisticated coffee finish." Master chocolatier Michael Recchiuti, founder of Recchiuti Confections, collaborated on the development of Astreas' ganache, which is made with a mix of two Valrhona couvertures.

In addition to Parazynski — who logged almost 60 days in space on five shuttle missions and then became the only astronaut to successfully summit Mt. Everest — the Astreas team includes fellow former NASA astronaut Greg Chamitoff and Vickie Kloeris, former space food system laboratory manager at NASA's Johnson Space Center in Houston.

"For long-duration spaceflights like a mission to Mars, food will play a critical role in astronaut performance, health and morale. It is especially exciting to see private companies advancing this frontier," said Kloeris.

You need not be an astronaut to try Astreas truffles. The company sells packages of 10 or 30 spheres for $50 and $120, respectively. Astreas recommends eating the spheres 15 minutess before a workout or study session to "lift brain fog" and provide the clear-headedness required for high-impact training or tasks.

Astreas was founded in 2018 and was recognized by NASA three years later as a Phase 1 winner in the agency's Deep Space Food Challenge (competing as Mission: Space Food out of Mountain View, California). In addition to flying by the moon, Astreas' chocolates have been launched to the International Space Station.

"To have astronauts consuming it during Artemis II is an extraordinary validation of that vision," said Shahreen Reza, founder and CEO of Astreas.
