Host Steve House sits down with dietitian Alyssa Leib to tackle the big question: do endurance athletes really need supplements? Alyssa breaks down which options can actually make a difference, like protein powder and creatine, and which ones deserve more caution, including bicarbonate, greens powders, and caffeine. She explains why lab testing is essential before adding vitamins or minerals and shares tips on choosing safe, third-party tested products. Alyssa emphasizes “food first” as the priority, and then how supplements can help fill gaps when training, traveling, or on expeditions. The conversation wraps up with a look at future trends like ketones and a reminder to approach all supplement claims with a healthy dose of skepticism.Special Offer to Listeners: Receive free four week samples of our most popular training plans, visit uphillathlete.com/letsgoWrite to us at [email protected]
