L-citrulline | 1,010mg 

L-citrulline has shown to be an effective supplement for targeting healthy circulation. It is converted to L-arginine by the kidneys over time, thus producing a longer lasting supply of Nitric Oxide (NO) to the body. Increased NO means increased blood flow which translates directly to better overall health, healthy blood pressure levels and enhanced sexual performance and endurance.

Side effects/cautions: There are no reported side effects of L-citrulline. You should not take L-cittruline if you take Nitrates for heart disease or ED drugs such as Cialis, Levitra, or Viagra.
