Ashlyn Harris's and Ali Krieger's Must Haves: From Adidas Sneakers to Ultra-Luxe Coffee

Harris is a big advocate of supplements and uses them to help with recovery. "You go into these extreme intense workouts and you push your body to the limits and you're very sore," she says. "I really believe in doing all natural supplements that aren't prescription based." While you might not think of probiotics as recovery aids, both Harris and Krieger love Align Women's Dual Action Probiotic Supplement ($30), which targets two areas: gut and feminine health. By adding good bacteria to your gut, it helps soothe abdominal discomfort and monthly mood balance, which helps ensure you're performing your best.

Pro Tip: Probiotics are best taken on an empty stomach, so before breakfast or right before bed. "I have some really hard issues sleeping overall, just from years of playing," Harris says. Knowing she's doing what she can to take care of her body while she sleeps helps her catch some Z's.
