L-Citrulline Malate
Combines citrulline with malate, a compound involved in cellular energy production.
Niacin (Vitamin B3)

What's notably missing
Individual per-ingredient amounts are not published in the materials we reviewed. That's different from a hidden proprietary blend — the ingredients themselves are named — but the doses aren't.
âš Know before you start
Before your first capsule: read the exact panel on the bottle you receive, since amounts can vary by print run. Because Memodyne contains nitric-oxide precursor amino acids, show the label to your doctor first if you take blood pressure medication, blood thinners, or vasodilators.
