Penbutolol Sulfate & Nutrient Depletion
Also searched as Levatol. What the clinical evidence reports, what it may mean, and what to discuss with your pharmacist.
Penbutolol Sulfate has been associated with depletion of COENZYME Q10. This does not mean a deficiency will occur — it means these are worth knowing about and, if you take Penbutolol Sulfate long-term, worth raising with your pharmacist or healthcare provider.

COENZYME Q10
Insufficient EvidenceBETA-BLOCKERS
Beta-blockers are thought to inhibit coenzyme Q10 mitochondrial enzymes and decrease endogenous levels of coenzyme Q10. However, it is not clear if this reduction is clinically significant. There is no reliable evidence that coenzyme Q10 depletion contributes to beta-blocker side effects.
Coenzyme Q10 is a compound your cells use to produce energy, and it plays a role in keeping the heart and muscles working well. Penbutolol is a beta-blocker, and there is some research suggesting that drugs in this class may interfere with certain mitochondrial enzymes involved in making coenzyme Q10, potentially lowering the body's own supply. That said, the evidence here is rated insufficient, meaning scientists have not yet established whether this reduction actually causes any real-world problems. If you have concerns, it is worth bringing up with your pharmacist or doctor rather than starting any supplement on your own.
What Coenzyme Q10 (CoQ10) does & food sources
CoQ10 helps cells produce energy and acts as an antioxidant; heart and muscle tissue use it heavily.
Common food sources:
- Organ meats and fatty fish
- Whole grains
- Nuts and seeds

What to discuss with your clinician
There is no routine blood test for CoQ10 in everyday practice. If you have new, unexplained muscle symptoms on a medication linked to CoQ10 (statins are the best-known example), talk to your prescriber before changing anything — symptoms have many possible causes and your prescriber has several options.

Supplement considerations
CoQ10 is generally well tolerated, but evidence for supplementing (for example, for statin muscle symptoms) is mixed. It may also modestly affect warfarin — check with your pharmacist before combining.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

Caution: Do not stop a prescribed medication because of this association — discuss any symptoms with your prescriber first.

More about Penbutolol Sulfate
What drug-induced nutrient depletion means
Some medications can, over time, lower the levels of certain vitamins, minerals, or other nutrients — through reduced absorption, increased loss, or changes in how the body uses them.
Association is not deficiency
An entry here means a depletion has been reported or studied — not that it happens to everyone, or that you are deficient. Dose, duration, diet, and your own health all matter.
Evidence varies by pair
Some drug–nutrient links (like metformin and vitamin B12) are well studied; others rest on limited or preliminary research. Each entry shows the evidence rating from our licensed clinical database.
When to ask about labs
If you take an associated medication long-term, ask your healthcare provider whether monitoring is appropriate for you. Not everyone needs testing — your provider can weigh your dose, duration, and symptoms.
Don't self-supplement blindly
Supplements are not risk-free: some can interact with medications, and some (like potassium or magnesium) can be risky with kidney disease. Talk to your pharmacist before adding anything.
Never stop a medication over this
These medications are prescribed for good reasons, and the benefit usually far outweighs a manageable nutrient consideration. Any change belongs in a conversation with your prescriber.
Food first, usually
For many nutrients, a varied diet covers the gap. Each entry lists common food sources; a supplement is a decision to make with your pharmacist or provider, not a default.
