Earlier this year, Shiffrin spent a month at a training camp in Chile, and that's when she hopped on the AG1 Pouch, 30-Day Supply ($99) train. "I started using it before we went to Chile because you're not really supposed to eat the raw vegetables and salads and things like that," she says. (And she did, unfortunately, still get food poisoning while she was there.) "One way to get those nutritional pieces, you can do it through a green powder. I don't think it's as good as just eating proper food. But when you don't have access to that — this is what I've been researching — it seems to be a good alternative."
Pro Tip: Shiffrin is spot-on with her green-powder knowledge. Green powders "can be a great option when you're traveling or on the road and do not have as much access to fresh fruits and veggies, Marissa Meshulam, MS, RD, CDN, founder of MPM Nutrition, previously told POPSUGAR. "Plus, they tend to be a quite concentrated source of vitamins, minerals, and antioxidants, meaning you're able to take in way more than you would typically be able to eat, which can provide an extra boost of the nutrients."
