Chondroitin supplementation reduces the risk of myocardial infarction by about forty percent
Supplementation with chondroitin reduces the risk of a heart attack in people with an increased risk of cardiovascular disease. Relatively low doses protect as well as high ones.
Mazzuchelli extracted the files of 23,585 Spaniards who had suffered a heart attack. He compared these with the files of 117,405 Spaniards who resembled the first group in as many respects as possible, but had not had a heart attack.
Mazuchelli calculated that the use of chondroitin reduced the risk of a heart attack by 43 percent.
Glucosamine supplementation had no effect on myocardial infarction.

The researchers also found that the dosage used seemed to have no influence. A daily dose of more than 800 milligrams protected about as well as a dose of less than 800 milligrams.
When the researchers broke down their data, they saw that chondroitin supplementation protected both men and women, in both over-70s and under-70s, and in both NSAID users and non-users.
Remarkably, the protective effect of chondroitin only came to light in study participants with an increased risk of cardiovascular disease.
