to get an idea of the quality of the material available, Omega just tested powder from a US based supplier, it came out at 10% CEE. Probably because it came by sea and has been sitting in a hot warehouse. Unfortunately most suppliers, distributors and retailers often store supplements in wearhouses that are not air conditioned, often degrading the product over time especially during the summer months.
The material for Purecee was flown in and has been stored at or below 70 degrees through all points of manufacture, transport and storage.
