Potential nutrient considerations for your selected medication

Tiaprofenic Acid

FOLIC ACID

Insufficient Evidence

NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs)

It is unclear if NSAIDs can reduce serum folate levels.

Folate-dependent enzymes are inhibited in vitro by NSAIDs with carboxylic acid-containing side chains. The clinical significance of this inhibition is unknown. For information on foods that are rich in folate, see our chart.
Taking Tiaprofenic Acid? Insufficient evidence to rate; clinical significance is not known. ⓘ
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.

Caution: High-dose folic acid can mask vitamin B12 deficiency, so the two are often evaluated together.

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.

Disclaimer: This checker finds which nutrients might be depleted by prescription or over-the-counter medications. Each nutrient depletion issue is rated based on clinical significance. Use your own professional judgment prior to making clinical decisions.

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.
