Nitric oxide (NO) is a widespread signalling molecule that participates in virtually every cellular and organ function in the body (1).

The main site of the molecule’s synthesis is the inner layer of blood vessels. It relaxes blood vessels and due to this improves the blood flow in the heart and lowers the blood pressure.(2)

In the immune system, nitric oxide is produced by macrophages, which are a type of leukocyte (white blood cell) that engulfs bacteria and other foreign particles such as viruses that have invaded the body. Nitric oxide is generated by phagocytes (monocytes, macrophages, and neutrophils) as part of the human immune response.(3) NO is also an effective component in the eradication of viruses. Viral replication is inhibited by the induction of iNOS and the subsequent production of NO. This has been shown for Deng Virus (4), HIV-1, coxsackievirus (5), influenza A and B, rhino virus, CMV and Corona Virus)(6).

How can we increase the endogenous NO production ? The source for NO is the amino acid L- Arginine. By the action of the enzyme Nitric Oxide Synthase (NOS) NO is formed from L-Arginine.

The enzyme NOS needs the coenzyme NADH (Nicotinamide Adenine Dinucleotide Hydride) for full functionality. As shown by Prof.T. Malinski (Ohio University) the increase of NO-synthesis by NADH supplementation is at least ten times greater than the effect of any other substance). (T. Mailinksi, personal communication). In other words a combination of L-Arginine and NADH increase the endogenous NO production remarkably and can thus destroy the COV-2 virus in infected patients which have developed SARS.

There is a nutritional supplement available which contains L-Arginine and NADH, the brand name of which is NADH VISION.
