David Beckham’s IM8 supplement brand, co-founded with Prenetics, has sent specially designed 3D organoids — miniature, simplified versions of human tissues — into space to study accelerated aging, leveraging microgravity’s unique environment that will speed up this process. With the month-long space experiment underway aboard the International Space Station (ISS), the researchers will examine the benefits of IM8’s patent-pending ingredient, Cell Rejuvenation Technology 8 (CRT8), which combines “nature’s most potent compounds to support cellular renewal and longevity.”
