I had a bit of a look around, but you might have done this already anyway. On Amazon I found this info: Ultra Health Group is a division of Redrose Manufacturing Limited. All the products are formulated by in house Chemists and manufactured in our own laboratories in County Durham UK to GMP and ISO 2000:90001 Quality Assurance. Googles Redrose manufacturing ltd http://www.redrosemfg.com/nutraceutical-supplement-manufacturing http://www.redrosemfg.com/blended-powders-sports-nutrition I never heard of them before though, but apparently they have been around for a long time. Maybe you can check that out to make sure.
