FOLIC ACID
Insignificant DepletionASPIRIN
Aspirin may decrease serum folate levels by reducing binding to plasma proteins, especially when large doses are taken regularly (e.g., for treatment of rheumatoid arthritis). But there doesn't seem to be an increase in urinary folate losses and red blood cell levels remain normal. This suggests folate is being redistributed in the body and deficiency isn't likely. For information on foods that are rich in folate, see our chart.
Folic acid is a B vitamin your body uses to make healthy red blood cells and support cell repair. Aspirin appears to loosen folate's grip on certain carrier proteins in the blood, which can shift where folate sits in the body, but research shows it does not actually flush more of it out through the kidneys, and red blood cell folate levels stay normal. Because of that, this is rated insignificant, meaning most people taking this medication do not need to worry about it or add a supplement. If you have concerns or eat a diet low in folate-rich foods, a quick conversation with your pharmacist is always worthwhile.
What Folic acid (folate) does & food sources
Folate is needed for cell division, red blood cell formation, and healthy fetal development.
Common food sources:
- Leafy green vegetables
- Beans, lentils, and peas
- Fortified grains and cereals
- Citrus fruits

What to discuss with your clinician
Ask your provider whether folate monitoring or supplementation is appropriate for you — this matters most before and during pregnancy, and with long-term use of certain seizure or arthritis medications.

Supplement considerations
Folate needs are individual. With some medications (for example, methotrexate), folic acid is often prescribed deliberately on a specific schedule — follow your prescriber's instructions rather than adding your own.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

VITAMIN C
Insignificant DepletionASPIRIN
Aspirin reduces tissue and leukocyte uptake of vitamin C, leaving more in the plasma to be filtered into the urine and increasing elimination. It may also reduce absorption of vitamin C from the gut. These effects are dose-related. Vitamin C supplementation has been suggested for people taking high-dose aspirin long-term. Supplements aren't needed with the low doses of aspirin used for cardiovascular indications.
Vitamin C is something your immune cells and tissues depend on, and here is an interesting quirk: aspirin appears to interfere with how your cells take up and hold onto vitamin C, which can push more of it out through the urine. It may also slightly reduce how much your gut absorbs in the first place. That said, this combination product contains a low dose of aspirin, and the evidence rates this interaction as insignificant for most people, so a supplement is not something most patients need to worry about. If you take high-dose aspirin regularly for another reason, it is worth mentioning to your pharmacist.
What Vitamin C does & food sources
Vitamin C is an antioxidant that supports the immune system, collagen formation, and iron absorption.
Common food sources:
- Citrus fruits
- Bell peppers
- Strawberries and kiwi
- Broccoli and Brussels sprouts

What to discuss with your clinician
Frank vitamin C deficiency is uncommon with a varied diet. If your diet is limited and you take an associated medication, ask your provider whether your intake is adequate.

Supplement considerations
Vitamin C is water-soluble and generally low-risk at food-level intakes; very high supplemental doses can cause stomach upset and may not add benefit.

POTASSIUM
Moderate DepletionMETHYLXANTHINES
Methylxanthines like theophylline can reduce serum potassium levels, possibly by increasing intracellular uptake of potassium. Hypokalemia is most likely to occur after acute overdose of these drugs. However, reduced potassium levels can occur with therapeutic doses, and the incidence and degree of hypokalemia increases with increasing serum theophylline levels. Monitor potassium levels in people with other risk factors for hypokalemia. For information on foods that are rich in potassium, see our chart.
Potassium is a mineral your heart, muscles, and nerves depend on to work properly. The caffeine in this combination product is a methylxanthine, and methylxanthines like caffeine can nudge potassium out of the bloodstream and into cells, which quietly lowers the level circulating in your blood. This is rated a moderate concern, meaning it is something worth paying attention to, especially if you use this medication regularly or have other reasons your potassium might already run low. It is worth asking your pharmacist or doctor whether your levels should be checked.
What Potassium does & food sources
Potassium keeps nerve signals, muscle contractions, and heart rhythm working normally.
Common food sources:
- Bananas and citrus fruits
- Potatoes and sweet potatoes
- Beans and lentils
- Tomatoes and leafy greens
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
Potassium is routinely checked with basic blood work. If you take a medication associated with potassium loss (like some diuretics), ask your provider how often your electrolytes should be monitored.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
Do not start potassium supplements on your own. Both low and high potassium can affect heart rhythm, and several common medications (ACE inhibitors, ARBs, potassium-sparing diuretics) raise potassium.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Caution: Potassium supplementation can be dangerous in kidney disease or alongside potassium-raising medications — this is a decision for your prescriber, guided by lab results.

VITAMIN B12
Moderate DepletionASPIRIN
Clinical research suggests that using aspirin is associated with a higher prevalence of vitamin B12 deficiency when compared with nonusers. For information on foods that are rich in vitamin B12, see our chart.
Vitamin B12 is something your nerves and red blood cells genuinely depend on, so it is worth paying attention to. Clinical research has found that regular aspirin users tend to show lower B12 levels more often than people who do not take it, though exactly how aspirin interferes is not fully settled. Some evidence points to aspirin affecting how the stomach and gut absorb B12. Because this combination carries a moderate depletion rating, long-term users should ask their pharmacist or doctor whether their B12 level is worth checking.
What Vitamin B12 does & food sources
Vitamin B12 supports red blood cell formation, nerve function, and DNA synthesis.
Common food sources:
- Meat, poultry, and fish
- Eggs and dairy products
- Fortified cereals and nutritional yeast
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
If you take an associated medication long-term, ask your healthcare provider whether checking a vitamin B12 level (sometimes with methylmalonic acid) is appropriate — especially if you notice fatigue, numbness, tingling, or memory changes.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
B12 status is easy to check and low levels are usually straightforward to address, so testing before supplementing is often the sensible order. High-dose folic acid can mask a B12 deficiency, which is one reason B12 and folate questions are best sorted out together with your provider.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

Caution: B12 deficiency can look like other conditions — do not self-diagnose from symptoms alone.

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.
