COENZYME Q10

Insignificant Depletion

ANTIDIABETES DRUGS

Metformin and sulfonylureas can modestly decrease endogenous levels of coenzyme Q10, but coenzyme Q10 supplements are not likely to be needed for patients taking these drugs.

Some antidiabetes drugs, including metformin and sulfonylureas, appear to inhibit coenzyme Q10 enzyme activity and decrease endogenous levels of coenzyme Q10. However, there is no strong evidence that coenzyme Q10 depletion is the cause of antidiabetes drug-related side effects. Furthermore, taking coenzyme Q10 does not seem to improve fasting glucose levels or glycated hemoglobin in patients with diabetes.

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.

MAGNESIUM

Insignificant Depletion

INSULIN

Insulin can increase magnesium excretion.

Insulin can enhance the renal excretion of magnesium. Theoretically, it might lower magnesium stores; however, lower magnesium stores are common in patients with diabetes due to decreased intake and osmotic diuresis resulting in increased magnesium excretion. For information on foods that are rich in magnesium, see our chart.

What Magnesium does & food sources

Magnesium is involved in muscle and nerve function, heart rhythm, blood sugar control, and bone health.

Common food sources:

  • Nuts and seeds (almonds, pumpkin seeds)
  • Whole grains
  • Leafy green vegetables
  • Beans and legumes

What to discuss with your clinician

Ask whether a magnesium level is worth checking if you take an associated medication long-term — particularly with symptoms like muscle cramps, twitching, or palpitations. Blood levels do not always reflect total body stores, which is worth discussing too.

Supplement considerations

Magnesium supplements come in many forms and can cause loose stools at higher doses. They can also bind some medications in the gut (certain antibiotics, thyroid medication), so timing matters — check with your pharmacist.

Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

Caution: Magnesium supplementation can be risky in kidney disease, where magnesium can accumulate — always check with a clinician first if your kidney function is reduced.

Important

This tool is educational and is not a substitute for professional medical advice. An association is not a diagnosis and does not mean a deficiency will occur. Always talk to your pharmacist or healthcare provider before starting, stopping, or changing any medication or supplement.

Understand the basics

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.

Common questions

Nutrient depletion FAQs

Can medications really deplete nutrients?
Yes — some medications can lower levels of certain vitamins, minerals, or other nutrients over time, by reducing absorption, increasing loss through the kidneys or gut, or changing how the body uses them. Well-known examples include metformin (vitamin B12) and proton pump inhibitors like omeprazole (magnesium and B12). How much it matters varies a lot between medications and between people.
Does an entry in this checker mean I am deficient?
No. An entry means a depletion has been reported or studied with that medication — it does not mean it happens to everyone, or that it has happened to you. Dose, how long you have taken the medication, your diet, and your overall health all influence the actual risk. Think of the results as conversation starters for your pharmacist or doctor, not a diagnosis.
Should I take a supplement if my medication appears here?
Not automatically. Supplements are not risk-free — some interact with medications (for example, calcium, magnesium, iron, and zinc can reduce absorption of certain antibiotics and thyroid medication), and some can be risky in kidney disease. The better first step is usually to ask your healthcare provider whether testing or dietary changes make sense for you.
What labs should I ask about?
It depends on the nutrient. Some, like vitamin B12, vitamin D, potassium, magnesium, and sodium, have routine blood tests; others, like CoQ10, are not usually tested in everyday practice. Each nutrient entry in this tool notes what is commonly discussed. Your provider can decide whether testing is appropriate — routine testing is not necessary for everyone.
Can supplements interact with my medications?
Yes — that is one of the main reasons not to start supplements blindly. Interactions can change how much of a medication your body absorbs or how it works. You can check specific products and ingredients against your medications with our drug–supplement interaction checker, and confirm anything important with your pharmacist.
Where does this information come from, and how is it reviewed?
The depletion records come from the Natural Medicines (Therapeutic Research Center) database — an evidence-graded clinical reference used by pharmacists and clinicians — and are displayed as published, with their evidence ratings and citations. The surrounding plain-English education is written and reviewed by licensed HelloPharmacist pharmacists.
