What supplements do Jocko and Echo take?

Jocko Willink and Echo Charles primarily take supplements like Krill Oil and Glucosamine, which Jocko has been using for over ten years. This regimen began due to a persistent shoulder injury that significantly improved after starting these supplements, though Jocko is unsure which of the two was directly responsible 1. Additionally, they recommend supplements from the brand Onnit and emphasize the quality and effectiveness of their products. Echo Charles personally highlights Krill Oil's significance for joint health and mentions its comparison to creatine in terms of benefits, noting a general preference for supplements that show tangible results 2 3.
