The 28-year-old star of The Marvelous Mrs. Maisel said that the fortifying drink helped her maintain her weight — and stave off illness — during filming. “My stay-healthy secret when I’m working 14- or 15-hour days on Mrs. Maisel is bone broth. For the first season of the show, I was feeling very tired. And because I have a fast metabolism, I felt like I was dropping weight in an unhealthy way. Bone broth has collagen and fat in it, along with all kinds of vitamins and minerals, and I really think it helped me,” Brosnahan told SHAPE for their March cover. “I was the only person on our set who didn’t get sick that season.” Ben Watts The actress — who recently nabbed her second consecutive Golden Globe award and her first Screen Actors Guild award for her role as 1950’s comedian Miriam Maisel — also finds that exercise makes her “focused and clearheaded,” though it isn’t always possible to fit in a workout.
