Naturally increase nitric oxide with everyday foods for better energy and circulation.
Watermelon doesn’t contain nitrates like leafy greens do, but it still supports nitric oxide in the body. It’s one of the best natural sources of L-citrulline, an amino acid that helps the body make nitric oxide.
Some studies have linked watermelon juice to better blood flow and exercise recovery, thanks to its role in widening blood vessels.
Most of the citrulline is found near the rind, but any fresh watermelon can contribute. It’s an easy option in smoothies, juices, or on its own.
