An amino acid tied to nitric oxide production and blood flow — worth a doctor's input if you take blood pressure medication.
L-Citrulline is an amino acid the body converts toward nitric oxide, a compound involved in relaxing and widening blood vessels, and it's one of the more research-backed ingredients in this category for blood flow specifically.
Because of this mechanism, if you take medication for blood pressure or a heart condition, it's worth talking to your doctor before starting a product containing L-Citrulline, since combining blood-flow-active ingredients with certain medications is a reasonable thing to flag with a healthcare provider first.
We don't have a confirmed dose for this ingredient in JellyRock specifically, which makes it harder to fully assess potential interactions on your own.
