HelloPharmacist Scorecard of Lithium Synergy by Designs for Health
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
Lithium Synergy contains 3 active ingredients. Vitamin B12 supports nerve function and red blood cell formation.
Lithium is a mineral that has been studied for mood and neurological support, though supplement forms are not as well studied as prescription lithium medications. Trimethylglycine is an amino acid derivative.
The capsule also contains microcrystalline cellulose and vegetable stearate as inactive ingredients.
Does it work?
Strong evidence
Vitamin B12 in this product is effective for treating B12 deficiency and a rare absorption disorder called Imerslund-Grasbeck disease, and is likely effective for cyanide poisoning; it is possibly effective for canker sores and postherpetic neuralgia (nerve pain after shingles). For lithium, the evidence we hold rates its usefulness for alcohol use disorder, Alzheimer disease, ALS, and anorexia nervosa as insufficient—meaning we don't have reliable data to say whether it works for these conditions.
We hold no effectiveness data for trimethylglycine.
How safe is it?
Well-documented data
Vitamin B12 is generally very well tolerated; excess is removed in your urine and there's no established upper limit. Allergic reactions such as rash are possible but rare.
Lithium, by contrast, has a narrow safety margin and requires blood monitoring when used as a prescription; supplement forms are not well studied at their lower doses. Common side effects with lithium can include tremor, muscle weakness, weight gain, increased thirst and urination, fatigue, and gastrointestinal symptoms.
Lithium is not safe in pregnancy—it crosses the placenta and has been linked to birth defects—and should be avoided during breastfeeding unless closely supervised by your doctor, as it passes into breast milk.
Meds to double-check
Major interaction found
Before taking Lithium Synergy, check with your doctor or pharmacist if you use serotonergic drugs (SSRIs, SNRIs, or other antidepressants), diuretics (water pills), NSAIDs, antipsychotics, blood pressure medications (especially ACE inhibitors or calcium channel blockers), skeletal muscle relaxants, anticonvulsants, or metformin. Lithium's interactions are serious and can raise drug levels or mask dangerous side effects.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
This product is designed for those exploring lithium and B12 supplementation, but lithium's narrow safety window and extensive medication interactions make it one to discuss with your doctor or pharmacist before you start. If you take any blood pressure medication, diuretic, antidepressant, NSAID, or other regular medication, clear this product with your own healthcare provider first.
Stop and contact your provider immediately if you notice tremor, confusion, muscle weakness, or unusual thirst or urination.

Lithium Synergy by Designs for Health Drug Interactions
HelloPharmacist Interaction Report
Lithium Synergy by Designs for Health contains lithium and vitamin B12, both of which interact with medications.
Lithium carries the most serious concerns: it poses Major-severity risks with serotonergic drugs (including SSRIs for depression and anxiety) and diuretics (water pills), where it can increase serotonin syndrome risk or raise lithium levels to toxic ranges. Vitamin B12 has a Minor interaction with metformin, a common diabetes medication that can lower B12 levels over time.
Read the full breakdown — every affected drug type, severity by severity
Lithium also interacts with several other drug types at Moderate severity. These include skeletal muscle relaxants (used during surgery or for muscle spasms), NSAIDs like ibuprofen and naproxen, antipsychotic medications, blood pressure drugs called ACE inhibitors, calcium channel blockers, and anticonvulsants used for seizures or nerve pain.
In each case, lithium may raise drug levels, prolong their effects, or increase unwanted side effects. We could not check trimethylglycine for interactions.
Altogether, these interactions span 535 individual medications. Because lithium has a narrow therapeutic window—meaning the difference between an effective dose and a toxic one is small—you'll need to review your complete medication list with your doctor or pharmacist before starting this product, especially if you take any of the drug types mentioned above.

For each ingredient in Lithium Synergy with known interactions, here are the types of medications they 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.
Vitamin B12
Metformin (Glucophage)
Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.
