About Global Nutritional Research (GNR)

GNR_logo Global Nutritional Research (GNR) was founded in 2007 by brothers Justin and Mackie Barch. GNR’s first product, Clotamin, was created to meet the unmet need of a multivitamin for people on blood thinning medications like warfarin.

Clotamin is specially designed without vitamin K and adjusted levels of other vitamins to be taken without affecting blood thinning medications. Clotamin is available for purchase online and at select independent pharmacies.

GNR plans to develop more products, like Clotamin, for people on blood thinners, as well as, other specialty/niche markets.
