Have purchased Green Lipped Mussel extract twice (and I will continue to buy this) from Troo Health Care. The price of their products is incredibly reasonable - especially as the postage is free. The containers - not being round - use up much less storage space - and their products are made in UK. I have definitely benefited from the mussel extract - no side effects - and my arthritic joints are gradually feeling more comfortable. I would definitely recommend purchasing from company. Many thanks to Troo Health Care for providing such brilliant supplements!
