More Reasons Why People With Joint Pain Must Not Take Glucosamine!

Dr. Brian Rothbard

In my post – Glucosamine/Chondroitin – Is It Really Safe? – I talked about my experiences (when performing surgery) observing the destructive effect that Glucosamine/Chondroitin has on the joints, as well as numerous other not very pleasant side effects.

But, there are yet two more reasons to not use glucosamine as a ‘remedy’ for your joint pain.  One is where glucosamine comes from and the other is how it’s manufactured.

While it is true that some glucosamine products are vegetarian, most comes from ground up derivatives of shellfish, such as crabs, shrimp and lobster, from farms or coastal waters of China. As China has few laws against pollution, chances are good that these shellfish contain high amounts of lead and mercury, both of which are extremely toxic to your body.

Lead, associated with many health problems, when ingested, tends to travel to the digestive system, red blood cells, bone marrow, liver and nervous system.  Lead can cause weakness, abdominal pain, confusion, headaches, anemia, depression, vomiting, twitching, bad coordination and even seizures, coma and death.

Mercury, one of the most harmful toxins on the planet, is one of the most common dangerous toxins to accumulate in the body.  Once it’s in the body, it’s difficult to remove as it strongly binds to human tissues. Mercury not only suppresses the immune system, but also causes sensory impairment, skin itching burning, shedding and swelling, fast heart beat, high blood pressure and more.

One may wonder the value of ingesting products that may contain poison. But there is yet another reason to think twice before taking glucosamine. After seeing how it’s manufactured, you may want to look for another avenue to relieve your joint pain.

They were taken at what is claimed to be one of the largest glucosamine manufacturers in China, which claims to meet or exceed the Pharmacopeia guidelines (USP), that establishes standards to ensure the quality of medicines for human use.
