The lungs are composed of a network of tubular structures of various diameters which form multiple branches. These air-exchanging tubes are built of smooth muscle cells and their internal lining is made of a thin layer of endothelial cells. Smooth muscle cells allow lung tubules to contract and relax independently assuring uninterrupted airflow in the lungs and keeping air passages open.

In order to function optimally all cells building our lungs need to receive a constant supply of essential nutrients. Among them, the amino acid Arginine is important as the source of natural ‘relaxing factors’. A proper mineral balance of magnesium, calcium, and potassium is also important to support optimum contraction and relaxation of smooth muscle cells. Chronic deficiency of these nutrients can lead to spasms of the smooth muscle cells causing constriction of air passages and a variety of symptoms related to those systems. 

Similar types of cells also build our blood vessel walls, gastrointestinal tract, gall bladder and reproductive and urinary tract tubules. An optimal supplementation of cellular nutrients will not only positively affect the function of air passages in the lungs, but will also support the elasticity and optimum relaxation of blood vessels and all other organs built of smooth muscle cells.

Therefore a combination of vitamins, minerals, and essential nutrients present in the Dr. Rath Relavit Formula will also benefit everyone concerned with supporting lung capacity and healthy breathing.*



  • Key Synergy Nutrients:

    Arginine: A source for nitric oxide, the “relaxing factor” needed for optimum blood vessel relaxation.
    Calcium and Magnesium: Help to maintain an optimal balance of electrolytes in the cells and support blood vessel relaxation and contraction.
    Vitamin C: Increases the production of prostacyline, which supports blood vessel relaxation and optimizes blood viscosity. Vitamin C is present as mineral ascorbates which are gentle for the stomach. Citrus bioflavonoids support vitamin C in its function.
