I'll give you some highlights:
The raw material for the recalled heparin batches was processed in China from pig's intestines by the American pharmaceutical firm Scientific Protein Laboratories.[3][4][5] The U.S. Food and Drug Administration was quoted as stating that at least 81 deaths were believed to be linked to a raw heparin ingredient imported from the People's Republic of China, and that they had also received 785 reports of serious injuries associated with the drug’s use.[6] According to the New York Times, "problems with heparin reported to the agency include difficulty breathing, nausea, vomiting, excessive sweating and rapidly falling blood pressure that in some cases led to life-threatening shock."[4]
Upon investigation of these adverse events by the FDA, academic institutions, and the involved pharmaceutical companies, the contaminant was identified as an "over-sulphated" derivative of chondroitin sulfate, a closely related substance obtained from mammal or fish cartilage and often used as a treatment for arthritis.[3][7] Since over-sulphated chondroitin is not a naturally occurring molecule, costs a fraction of true heparin starting material, and mimics the in-vitro properties of heparin, the counterfeit was almost certainly intentional as opposed to an accidental lapse in manufacturing.[8] The raw heparin batches were found to have been cut from 2-60% with the counterfeit substance, and motivation for the adulteration was attributed to a combination of cost effectiveness and a shortage of suitable pigs in China.
When the FDA conducted an inspection of Baxter's Chinese Heparin supplier, it found serious deficiencies at the facility which the FDA detailed in a warning letter.[9][10]
The FDA has stated that it does not have the funds nor bear the responsibility to inspect on a regular basis overseas manufacturers of active pharmaceutical ingredients such as heparin.
In November 2008, the FDA seized eleven lots of heparin from Celsus Laboratories Inc., a manufacturer in Cincinnati, Ohio.[11]
I guess we have drifted the thread so far that I have no idea what your point is.
My point is: there are no definitive published scientific studies that support supplements as doing anything at all.
That point continues to be unmolested.
