Condition
Relative Energy Deficiency in Sport (RED-S)
Relative Energy Deficiency in Sport (RED-S) happens when an athlete's food intake falls short of what training and basic body functions need, so the body starts dialing down reproductive hormones, bone building, metabolism, and eventually heart and mental health. People often look at vitamin D and calcium for it, given their role in bone health, but little research on them in this setting has been reviewed here so far. Nothing here yet shows how well any supplement works for RED-S, so eating enough remains the central issue.
