What is the difference between BioTears Oral GelCaps and TheraTears Nutritionals?
Night and Day. TheraTears Nutritionals are designed around the metabolic conversion of plant and fish based Omega 3 fatty acids, which, primarily, convert downstream to the series three prostaglandin (PGE3). Simply said; the Omega 6 GLA series one prostaglandins (PGE1) produced by BioTears Oral GelCaps are far more tear and mucous gland specific than the series three prostaglandins in TheraTears Nutritionals. Thera Tears Nutritionals does not include Omega 6 fatty acid, gamma-linolenic-acid (GLA), which is required to produce tear specific PGE1. BioTears includes the best quality available Omega 6 and Omega 3 fatty acids to address the inflammatory process frequently associated with all three layers of the tear film.
