Tennis champion Serena Williams and actor Jake Gyllenhaal are the latest celebrity investors in Eat Just, a brand known for JUST Egg, a vegan egg replacer made from mung beans. The duo are also part of the brand’s “Really Good Eggs” campaign and are appearing in two separate, 30-second commercials.

Gyllenhaal’s appearance is themed around next-level, secret celebrity workouts and shows him eating JUST Egg to refuel after a round of underwater jiu jitsu and before he is scheduled to do “galactic robo-knight training.”

Williams’ commercial spot takes a different approach. She is pictured in her home kitchen surrounded by scientists, nutritionists, and trainers that optimize her every move, including what she consumes for breakfast.
