Blood-flow pairing.

Beetroot delivers dietary nitrates that the body converts to nitric oxide, while L-arginine is a direct precursor the nitric-oxide enzyme uses, so the two feed the same blood-flow pathway from two entry points.

What to do

Fine as a pre-workout pairing for blood flow, though L-citrulline is usually a better-value arginine source since oral arginine is largely broken down in the gut. Take them 1 to 2 hours before training, and expect a mild blood-pressure-lowering effect.
