Hello,
Perhaps somewhat surprisingly, chondroitin may be good for your heart - see here and/or here (the same site), for instance.
This makes me wonder whether I should get some purified chondroitin sulfate. The website above cites a product by Karuna as a legit supplier, but well, apparently not even that may contain what (or as much as) it claims to contain (link). Apparently the same goes for many other chondroitin suppliers.
This site promotes PURIFIED CHONDROITIN SULFATES by Biotics Research Corporation as the real thing. Do you have any idea (or experience) with their products? Or perhaps are you aware of any other sites to get legit purified chondroitin sulfate (ideally, but not necessarily, in Europe)?
Thank you
