Red yeast rice did absolutely nothing for me and upon further research found
Red yeast rice products that have considerable amounts of monacolin K may effectively lower blood cholesterol levels, blood glucose levels, and blood pressure. They may also reduce the risk of heart problems and death in people with metabolic syndrome. (Metabolic syndrome, also called insulin resistance syndrome, is a group of conditions that raise the risk of heart disease, diabetes, and stroke.) But, because of the levels of monacolin K, these products are considered by the FDA to be unapproved new drugs and are not sold legally in the United States.
Other red yeast rice products may contain very little monacolin K, and it’s unknown if these products are effective in reducing cholesterol levels or improving other areas of health. Some products have levels of monacolin K that are below the level known to lower cholesterol in clinical trials.
