Are Biosyntrx formulations FDA approved, and has the formulation been clinically studied?
By law (Dietary Supplements Health and Education Act, Oct 1994) the FDA does not approve or disapprove dietary supplements. They do however, closely monitor dietary supplement label claims. Biosyntrx formulations do not contain nutrients that exceed the Institute of Medicines (IOM) published upper-limit safety levels.

BioTears has been clinically studied by thought leading ophthalmologists and optometrists using all of the subjective and objective clinical markers avaible. This includes: tear break up time (TBUT), Schrimers, ZoneQuick, ocular surface staining, and lactoferrin assay. The outcomes strongly suggest improvement in tear film chemistry, as well as improved ocular surface health in approximately 75% of dry eye patients studied.
