GLUTATHIONE
Insufficient EvidenceACETAMINOPHEN
Chronic or excessive acetaminophen has been associated with low levels of glutathione. Usually a cysteine containing supplement is used to replenish glutathione. Cysteine is converted to glutathione in the body.
Glutathione is an antioxidant your body makes naturally to protect cells from damage and help break down certain substances, including acetaminophen itself. When the liver processes acetaminophen, it actually uses up glutathione as part of that process, and taking large or chronic doses over time has been linked to lower glutathione levels. That said, the current evidence is rated insufficient, meaning researchers have not yet established how meaningful this is for people taking normal doses. If you take acetaminophen regularly and have concerns, it is worth bringing up with your pharmacist or doctor.

More about Acetaminophen, Phenylpropanolamine
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.
