It's expensive in the US because one company has exclusive sales here (patent protection?), but you could try calcefidiol, weekly dose and is supposed to get levels up rapidly. Apparently it's the common form to take in Spain, and it's further down the metabolic pathway vs cholecalciferol. (I take but still have to get levels checked)
