Although it may seem that Lungshield and Sanvitone are the same, they are not. Sanvitone has been on the market since 2004 and has helped many clients suffering from asthma, COPD, and other respiratory infections. The ingredients may appear similar, but the quantity and raw material forms are not the same, and neither is the actual lab formulation. Sanvitone offers a more affordable version of Lungshield, which is slightly more potent. However, if Sanvitone works just as well as Lungshield for you, there’s no reason to buy Lungshield instead.
