Evidence shows most cardiovascular benefit is achieved at 10–20 mg for the majority of people. Higher doses often bring diminishing returns but higher odds of side effects.
Ubiquinol (the more bioavailable form) at 100–200 mg per day is commonly tried. Several small studies and a lot of anecdotal feedback suggest it helps muscle symptoms and energy for a subset of users. Get clearance from your prescriber first.
Useful tests to track include:
- Creatine kinase (CK) – muscle marker
- ALT/AST – liver function
- HbA1c or fasting glucose – sugar control
- Full lipid panel (consider ApoB or LDL particle number for deeper insight)
- Add muscle- and heart-friendly habits
