Membrin® by Ortho Molecular Products

Membrin is a once-daily cognitive support capsule for adults who want a structured ginkgo plus vinpocetine plus huperzine A combination, rather than three separate single-ingredient products. It fits people who already cover the basics (sleep, hydration, daily movement) and want a focused formula to layer on top, specifically for cerebral blood flow and antioxidant support at the level of brain tissue. It is not a stimulant and not a substitute for sleep or for clinical evaluation if cognitive concerns are persistent or worsening.

Ginkgo biloba is the most well-studied botanical for cognitive support; it improves microcirculation, supports cerebral blood flow, and protects neurons from oxidant-induced damage. Vinpocetine, derived from the West African plant Voacanga africana, crosses the blood-brain barrier and has vasorelaxant effects on cerebral smooth muscle. Huperzine A, a purified component from Chinese club moss, supports acetylcholine signaling, the neurotransmitter most associated with attention and memory. The three ingredients are layered to address blood flow, cellular protection, and neurotransmitter handling at the same time.

Take 1 capsule daily, in the morning or early afternoon, with or without food. The cholinergic component can produce vivid dreams or restless sleep if taken too late in the day. If you are sensitive or run on the lower end of typical resting heart rate or blood pressure, start every other day for the first week and increase as tolerated. Many users run an 8 to 12 week period of daily use, then break for one to two weeks to reduce tolerance.

If you take prescription medications, could become pregnant, or are scheduled for surgery, talk to your clinician before starting and review the warnings below.
