L-Citrulline and Nitric Oxide Cycling

By MemoHoney Research Team · Reviewed by Dr. Harold Bennett, M.D. · Updated June 2026

L-Citrulline plays a distinctive supporting role in MemoHoney's circulation-focused formula. Here's why it matters.

What Is L-Citrulline?

L-Citrulline is a precursor the body recycles back into arginine, creating a continuous cycle of nitric oxide production.

Sustains Blood Flow During Stress

This recycling cycle keeps cerebral blood vessels relaxed and blood flow steady even during moments of stress, fatigue, or poor sleep.

Two Forms, Complementary Roles

MemoHoney uses both L-Citrulline HCl and L-Citrulline Malate, with the malate form also supporting cellular energy and metabolic waste clearance.

L-Citrulline in MemoHoney

MemoHoney pairs L-Citrulline with L-Arginine for a complete nitric oxide cycle — see the ingredients page and the current MemoHoney discount on the MemoHoney official website.

L-Citrulline supports circulation and is not a treatment for any condition. Consult your doctor before use if you take vasodilator medication.
