I purchased " Triple Strength Hyaluronic Acid " from PureClinica to help alleviate my osteoarthritis because it made the bold claim to " Improve joint flexibility, and plump and fill wrinkles " ... only to find that the label on the bottle says > " IMPORTANT: This supplement is not medicine and will not prevent, diagnose, restore, correct or modify any physiological condition in humans " So as we see to claim " improving joint flexibility " and then having a disclaimer denying that this product can do anything is in direct violation of ASA regulations ! I have emailed Pureclinica 6 times via their website and once by direct email. No one ever got back to me by phone, email or letter - there has been NO COMMUNICATION ! I even called the office in London, and was met with an answering machine, I tried to leave a message but the machine only allow for 3 seconds recording - so I had to call again.. and very quickly said my mobile number and asked if someone could call me back, no one ever did. I eventually did get my refund from a Paypal claim, but I had to put a lot of unnecessary effort in just to get some helpful communication from PureClinca. I'm very surprised they have so many positive feedback, although I have heard of businesses falsifying these reviews, it is very easy to do ( please note: I am not accusing PureClinica of carrying out this illegal and unfair practice ) ... I just want to highlight that companies are doing it and it is very easy to make your company seem spotless ! I will never use this company again, I don't trust them or their products, the hyaluronic acid did not help or alleviate my joints at all ! .. there was NO effect, I took it daily, as instructed for 4 weeks .. on an empty stomach in the morning ... and there was absolutely NO increase in flexibility of joints. Which is confusing, because under research oral hyaluronic acid was found to help, which makes me question how pure this product actually is ?
