Reality in Liposomes and Lipid Particle Deliveries

Recently, Valimenta Labs (Emek Blair) has released private label glutathione products (NuMedica and PureAbsorb reviewed here) and has put forth marketing literature comparing themselves to Quicksilver’s premium Liposomal Glutathione. IF any of it were true, it would be a good value proposition. This prompted us to analyze these and two other glutathione products for liposome size and glutathione content.
