The Recovery Fuel Lab Recover. Refuel. Perform. Evidence

Evidence and references

Every recommendation in the lab comes from these peer-reviewed sources. The ranges are general guidance for healthy athletes and teach the principles; they are not individual prescriptions.

How the lab sets its numbers
