HelloPharmacist Scorecard of DRN Lithium 250 mcg by Kirkman

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: lithium citrate at 250 micrograms per capsule. Inactive ingredients—hypromellose, water, and microcrystalline cellulose—are the capsule material and binding agents.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Lithium product and its label doesn't state a use — see Lithium's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for lithium citrate supplements is not established in the data we hold. The product facts list several uses (alcohol use disorder, Alzheimer disease, ALS, anorexia nervosa, and asthma), but all of them are rated as having insufficient reliable evidence to rate—meaning the studies are too limited or unclear to confirm whether it works for those purposes.

The evidence, ingredient by ingredient Lithium

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Prescription lithium is generally well tolerated when used as prescribed and monitored, but it has a narrow safety margin—the difference between an effective dose and a toxic one is small. Supplement forms are not well studied, and it's unclear how lower doses affect side effects.

Common adverse effects with prescription lithium include tremor, fatigue, muscle weakness, weight gain, increased thirst and urination, and gastrointestinal symptoms. Lithium can also cause or worsen skin conditions like acne and psoriasis.

Pregnancy safety is rated as Possibly Unsafe—lithium can cross the placenta and has been linked to birth defects—so avoid it unless your doctor directs and monitors you. Lactation is rated Likely Unsafe because lithium passes into breast milk and may affect the infant; avoid unless supervised by a doctor.

Do not stop lithium abruptly; gradual tapering over at least 14 days is necessary to prevent relapse of bipolar symptoms.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This supplement carries serious interactions with common medications, especially antidepressants and water pills, and prescription lithium requires blood monitoring to stay safe—a practice not standard with supplements. If you're considering it, talk with your doctor or pharmacist first about whether it's appropriate for you and what you need to monitor.

Pregnancy and breastfeeding require medical supervision if you use lithium at all.

Lithium Citrate11 drug types · 515 drugs

Diuretic Drugs

Theoretically, taking lithium supplements with loop diuretics might increase lithium levels and adverse effects.
Thiazide diuretics and loop diuretics might reduce lithium excretion, particularly in sodium-restricted patients. If lithium is clinically indicated and other treatment options are unavailable or inadequate in patients using diuretics, lithium treatment can be initiated with extreme caution. Serum lithium should be measured frequently and the doses used should be the lowest dose ordinarily tolerated. It is unclear if this interaction would be clinically significant with the smaller doses found in lithium supplements.

Likelihood Probable Evidence D
Serotonergic Drugs

Theoretically, taking lithium supplements with serotonergic drugs might both mask and increase the risk of serotonin syndrome.
In a case report, a 67-year-old female with depression and bipolar disorder using lithium in combination with selective serotonin reuptake inhibitors (SSRIs) and other medications developed serotonin syndrome with symptoms of deep tendon hyperreflexia, muscle rigidity, tremor, and hyperthermia. However, agitation, one classical symptom of serotonin syndrome, was lacking. This was thought to be due to masking by lithium toxicity. Lithium can increase serotonin levels, thus, combining serotonergic drugs with lithium might increase the risk of serotonergic side effects including serotonin syndrome and cerebral vasoconstrictive disorders. It is unclear if this interaction would occur with the smaller doses found in lithium supplements.

Likelihood Probable Evidence D
Ace Inhibitors (Aceis)

Theoretically, taking lithium supplements with ACEIs might increase levels and adverse effects of lithium.
Concomitant administration of ACEIs with lithium may increase lithium concentrations. It is unclear if this interaction would be clinically significant with the smaller doses found in lithium supplements.

Likelihood Possible Evidence D
Anticonvulsants

Theoretically, taking lithium supplements with anticonvulsants might increase the risk of neurotoxicity.
Drugs such as carbamazepine and phenytoin seem to increase the risk of neurotoxicity. It is unclear if this interaction would occur with the smaller doses found in lithium supplements.

Likelihood Possible Evidence D
Antipsychotic Drugs

Theoretically, taking lithium supplements with antipsychotic drugs might increase the risk of encephalopathic syndrome.
Encephalopathic syndrome has been reported in multiple patients taking prescription lithium and antipsychotics concomitantly. Symptoms have included weakness and lethargy, fever, confusion, and extrapyramidal symptoms. In some patients, resulting brain damage was irreversible. Although there is no established causal relationship between these symptoms and the combination of lithium and antipsychotic medications, there is a theoretical relationship. It is unclear if this interaction would occur with the smaller doses found in lithium supplements.

Likelihood Possible Evidence D
Calcium Channel Blockers

Theoretically, taking lithium supplements with calcium channel blockers might reduce lithium levels and might also increase the risk of certain adverse effects.
Calcium channel blockers might reduce lithium concentrations. Monitor lithium levels with concurrent use. Calcium channel blockers might also increase the adverse neurological and gastrointestinal adverse effects of lithium. It is unclear if these interactions would occur with the smaller doses found in lithium supplements.

Likelihood Possible Evidence D
Methyldopa (Aldomet)

Theoretically, taking lithium supplements with methyldopa might increase the risk of lithium toxicity.
Concurrent use of methyldopa with lithium increases the risk of lithium toxicity. It is unclear if this interaction would be clinically significant with the smaller doses found in lithium supplements.

Likelihood Probable Evidence D
Methylxanthines

Theoretically, taking lithium supplements with methylxanthines might decrease lithium levels.
Xanthines such as aminophylline, caffeine, and theophylline (Theo-Dur, Theo-24, others) might increase the clearance of lithium. It is unclear if this interaction would be clinically significant with the smaller doses found in lithium supplements.

Likelihood Probable Evidence D
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)

Theoretically, taking lithium supplements with NSAIDs might increase lithium levels and adverse effects.
NSAIDs can decrease the renal clearance of lithium and increase lithium levels. It is unclear if this interaction would be clinically significant with the smaller doses found in lithium supplements.

Likelihood Probable Evidence D
Phenothiazines

Theoretically, taking lithium supplements with phenothiazines might decrease the levels and clinical effects of phenothiazines.
Concomitant use of lithium with phenothiazines might reduce lithium concentrations. Lithium might also reduce phenothiazine concentrations, making the pharmacokinetic effect unpredictable. It is unclear if these interactions would occur with the smaller doses found in lithium supplements.

Likelihood Probable Evidence D
Skeletal Muscle Relaxants

Theoretically, taking lithium supplements with skeletal muscle relaxants might prolong neuromuscular blockade.
Lithium might prolong neuromuscular blockade. It is unclear if this interaction would occur with the smaller doses found in lithium supplements.

DRN Lithium 250 mcg by Kirkman: Common Questions

Does DRN Lithium 250 mcg by Kirkman interact with any medications?
Yes. Based on its ingredients, DRN Lithium 250 mcg has a known interaction with 515 medications, including 259 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
DRN Lithium 250 mcg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm on an SSRI antidepressant?
No—this is a Major-severity interaction. Lithium with SSRIs may mask and increase the risk of serotonin syndrome, a serious condition. Talk with your doctor or pharmacist before considering this supplement.
What if I take a water pill for blood pressure?
Water pills can reduce how your kidneys clear lithium and raise lithium levels dangerously. This is a Major-severity interaction. Check with your doctor or pharmacist before taking this supplement.
Does this supplement actually work for depression or bipolar disorder?
The evidence we hold does not establish that it works. Prescription lithium is a proven mood stabilizer, but supplement forms are not well studied. Talk with your doctor about prescription options if lithium is appropriate for you.
Is it safe to take if I'm pregnant or breastfeeding?
No. In pregnancy, lithium is rated Possibly Unsafe and has been linked to birth defects—avoid it unless your doctor directs and monitors you. In breastfeeding, it's rated Likely Unsafe because lithium passes into breast milk. Talk with your doctor before considering it.
What are the most common side effects?
With prescription lithium, common effects include tremor, fatigue, muscle weakness, weight gain, increased thirst and urination, nausea, and skin issues. It's unclear how the lower dose in this supplement would compare, and lithium levels must be monitored to prevent toxicity.
Can I just stop taking lithium if I switch supplements?
No. If you're on prescription lithium, abrupt stopping can trigger a relapse of bipolar symptoms. Any change requires gradual tapering over at least 14 days under your doctor's supervision.
