So far so good, His cardiologist sends him for blood work every 6 months. Here is all that I can find that may be helpful for you.
Red yeast rice contains monacolin K, which can affect liver function.
It may lead to elevated liver enzymes, indicating liver stress or damage.
Kidney function can also be impacted, especially in those with pre-existing conditions.
Regular monitoring of liver and kidney health is advisable when using red yeast rice.
Consult a healthcare professional before starting red yeast rice, especially if you have liver or kidney issues.
Discontinue use if you experience symptoms like jaundice, dark urine, or abdominal pain.
