Frequently asked questions

If RYR contains a statin, why not just take a statin?

Good question. A prescribed statin offers standardized dosing, quality control, and clinician oversight.

Is RYR "natural" and therefore safer?

The "natural" label doesn't change the pharmacology. Monacolin K has the same mechanism as lovastatin.
