Exercise has been shown to induce the synthesis of the metabolite betaine (trimethylglycine) in the kidneys. Separately, delivery of betaine was developed as a therapy for the rare disease homocystinuria due to its ability to blunt the harmful buildup of homocysteine in that condition. Here, researchers briefly review recent developments in the understanding of the ability of additional betaine delivered as a therapy to act as an exercise mimetic, triggering some of the beneficial metabolic responses to exercise.

Recently, researchers identified the <a href="https:/…
