Red yeast rice extract supplement is sold over the counter in pharmacies and health food stores here in Singapore. Red yeast rice is a fermented product of rice. It contains lovastatin, which is what cholesterol-lowering statin drug contains. It is said that red yeast rice has cholesterol-lowering effect without the drug statin-like side effects such as muscle weakness (and that include your heart muscle) etc.
According to Professor Kerry Bone from the University of New England, it is still a controversial remedy as some clinical studies have found side effects similar to the drug statin. This is one of the reasons why it is not approved by TGA (Australia) and herbalist are not supposed to prescribe it.
Why is it sold in local stores? This is because health supplements are not fully regulated in Singapore. On the other hand, my practice is regulated by NHAA (National Herbalists Association of Australia) and TGA (Therapeutic goods act) of Australia. This is to ensure safe prescription for the patients. There are a list of ethics we need to follow. For example, I can’t sell multi-level marketing products as it is deemed conflict of interest.
Therefore, please do not assume everything is safe just because they are sold in a pharmacy or health food stores. Check with your qualified natural health care provider.
