HelloPharmacist Scorecard of Neuro-Protect by HoltraCeuticals
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
Neuro-Protect contains one active ingredient: lithium. The supplement also includes inactive ingredients—vegetable capsule material, microcrystalline cellulose (a binder), magnesium stearate (a lubricant), and silicon dioxide—that help form and deliver the capsule.
Does it work?
Couldn't assess
The evidence we hold for lithium in this product does not establish it as effective for alcohol use disorder, Alzheimer's disease, ALS, or anorexia nervosa. Each of these conditions is listed as having insufficient reliable evidence to rate.
If you're considering this supplement for a specific condition, it's worth discussing with your doctor whether the current evidence supports its use.
How safe is it?
Well-documented data
Prescription lithium is generally well tolerated when properly dosed and monitored, but it has a very narrow safety margin—your blood levels must be checked regularly to stay safe. Supplement forms of lithium are not well studied, so it's unclear how lower doses might affect side effects.
Common adverse effects from prescription lithium include tremor, fatigue, muscle weakness, weight gain, increased thirst and urination, and gastrointestinal symptoms; lithium can also worsen skin conditions like acne and psoriasis. Lithium is not safe in pregnancy—it can cross the placenta and has been linked to birth defects—and it passes into breast milk where it may harm an infant.
Avoid this product during pregnancy and breastfeeding unless your doctor specifically directs otherwise and monitors you closely. If you've been taking lithium and want to stop, do not stop abruptly; rapid drops in blood level can trigger a return of bipolar symptoms, so your doctor should taper it gradually over at least 14 days.
Meds to double-check
Major interaction found
Before taking Neuro-Protect, check with your doctor or pharmacist if you take serotonergic drugs like SSRIs (Major severity), diuretics or water pills (Major severity), muscle relaxants, NSAIDs or over-the-counter pain relievers, antipsychotics, blood pressure medications including ACE inhibitors or calcium channel blockers, or seizure medications. Lithium can dangerously raise levels of some of these drugs or create serious side effects, and you may need blood monitoring or a dose adjustment.
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.
Neuro-Protect is a single-ingredient lithium supplement with significant interactions involving blood pressure medications, diuretics, antidepressants, and many others—and lithium has a dangerously narrow safety window. If you're already on any prescription medication or considering starting this product, talk with your doctor or pharmacist first to make sure it's safe for you and won't interfere with your other drugs.

Neuro-Protect by HoltraCeuticals Drug Interactions
HelloPharmacist Interaction Report
Neuro-Protect by HoltraCeuticals contains lithium, which carries documented interactions with a significant number of medications.
The most serious concern is with serotonergic drugs (antidepressants like SSRIs)—combining lithium with these can both mask and increase the risk of serotonin syndrome, a potentially dangerous condition involving agitation, confusion, rapid heartbeat, and high body temperature.
Read the full breakdown — every affected drug type, severity by severity
Lithium also has Major-severity interactions with water pills (diuretics), which can raise lithium levels in your blood and trigger toxicity symptoms like tremor, confusion, and kidney problems. Additionally, it carries Moderate-severity interactions with muscle relaxants, pain relievers (NSAIDs), antipsychotic medications, blood pressure drugs (ACE inhibitors and calcium channel blockers), and seizure medications—each of which can either boost lithium levels dangerously or increase unwanted neurological effects.
Because lithium has a very narrow margin between an effective dose and a toxic one, and because supplement forms aren't well studied the way prescription lithium is, you'll want to run your exact medications through the interaction checker on this page before starting.
Altogether, these interactions span 515 individual medications.

For each ingredient in Neuro-Protect with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Lithium
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
