Below is general information about the safety of the known ingredients contained in the product Lithium Orotate. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally or parenterally and appropriately. Folic acid has been safely used in amounts below the tolerable upper intake level (UL). The UL for folic acid is based only on supplemental folic acid and is expressed in mcg folic acid. Dietary folate is not included in UL calculations, as dietary folate consumption has not been associated with adverse effects. The UL for folic acid in adults is 1000 mcg (6241). In cases of megaloblastic anemia resulting from folate deficiency or malabsorption disorders such as sprue, oral doses of 1-5 mg per day can also be used safely until hematologic recovery is documented, as long as vitamin B12 levels are routinely measured (6241,7725,8739).
POSSIBLY SAFE ...when L-5-methyltetrahydrofolate (L-5-MTHF), the reduced form of folate, is used orally and appropriately, short-term. L-5-MTHF has been used with apparent safety at a dose of 416 mcg daily for 16 weeks (104913,104914) and a dose of 113 mcg daily for 24 weeks (104920). A specific L-5-MTHF product (Metafolin, Eprova) has been used with apparent safety at a dose of 1.3 mg daily for 12 weeks (104912).
POSSIBLY UNSAFE ...when used orally in large doses, long-term. Clinical research shows that taking folic acid daily in doses of 800 mcg to 1200 mcg for 3-10 years significantly increases the risk of developing cancer and adverse cardiovascular effects compared to placebo (12150,13482,16822,17041). Doses above 1 mg per day should also be avoided if possible to prevent precipitation or exacerbation of neuropathy related to vitamin B12 deficiency (6241,6242,6245). However, there is contradictory evidence suggesting that higher doses may not be harmful. There is some evidence that doses of 5 mg per day orally for up to 4 months can be used safely if vitamin B12 levels are routinely measured (7725). Also, other clinical research suggests that folic acid supplementation at doses up to 5 mg, usually in combination with vitamin B12, does not increase the risk of cancer when taken for 2-7 years (91312). Very high doses of 15 mg per day can cause significant central nervous system (CNS) and gastrointestinal side effects (505).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
Folic acid has been safely used in children in amounts below the tolerable upper intake level (UL). The ULs for folic acid are based only on supplemental folic acid and are expressed in mcg folic acid. Dietary folate is not included in UL calculations, as dietary folate consumption has not been associated with adverse effects. The UL for children is: 1-3 years of age, 300 mcg; 4-8 years of age, 400 mcg; 9-13 years of age, 600 mcg; 14-18 years of age, 800 mcg (6241).
CHILDREN: POSSIBLY SAFE
when L-5-methyltetrahydrofolate (L-5-MTHF), the reduced form of folate, is used orally and appropriately.
One clinical study in infants aged 27 days and younger shows that consuming a formula containing L-5-MTHF (Metafolin, Merck & Cie) 10.4 mcg/100 mL daily has been used with apparent safety for up to 12 weeks (104918).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Folic acid 300-400 mcg is commonly used during pregnancy for prevention of neural tube defects (8739). Miscarriage rates and negative impacts on fetal growth have not been shown to increase with peri-conception supplemental folic acid intakes of 4 mg per day (91320,91322). However, other research shows that taking more than 5 mg per day during pregnancy may reduce development of cognitive, emotional, and motor skills in infants (91318). Also, the tolerable upper intake level (UL) of folic acid for pregnant or lactating women is 800 mcg daily for those 14-18 years of age and 1000 mcg daily for those 19 years and older (6241).
PREGNANCY AND LACTATION: POSSIBLY SAFE
when L-5-methyltetrahydrofolate (L-5-MTHF), the reduced form of folate, is used orally and appropriately, short-term.
L-5-MTHF has been used with apparent safety at a dose of 416 mcg daily for 16 weeks during lactation. Compared to folic acid, this form seems to further increase the folate concentration of red blood cells, but not breast milk (104913,104914).
LIKELY SAFE ...when lithium carbonate or lithium citrate is used orally and appropriately. Lithium carbonate and lithium citrate are FDA-approved drugs and have been used safely in clinical studies (15,97770). Lithium has a narrow therapeutic window and plasma levels must be monitored to avoid toxicity (15). Lithium levels should be drawn 12 hours after the last dose of lithium after steady state concentrations have been attained (approximately 3 days). Toxicity is most common at levels of 1.5 mEq/L, although some patients develop toxicity at levels less than 1 mEq/L (15,97770). There is insufficient reliable information available about the safety of lithium aspartate, lithium orotate, or other forms of supplemental lithium.
CHILDREN: POSSIBLY SAFE
when prescription lithium carbonate or lithium citrate is used orally and appropriately under medical supervision in children 7 years of age and older (15).
There is insufficient reliable information available about the safety of lithium aspartate, lithium orotate, or other forms of supplemental lithium.
PREGNANCY: POSSIBLY UNSAFE
when lithium carbonate and lithium citrate are used orally (15).
Lithium can cause fetal toxicity and increases the risk for cardiac and other abnormalities, including neural tube and urethral defects. However, it does not seem to increase the risk for preterm birth or low birth rate (15,9166,97770,104266). Some research suggests lithium might increase the risk for spontaneous abortion. Based on a meta-analysis of 2 population studies, taking lithium during pregnancy may increase the risk for spontaneous abortion when compared with the general population, but not when compared with patients with affective disorders not taking lithium during pregnancy (104266). This suggests that it may be the presence of affective disorder itself, or the possible associated use of other teratogenic drugs or substances during pregnancy, which may increase the risk for spontaneous abortion.
When the potential benefits to the mother and child outweigh the possible risk to the fetus, prescription lithium may be used with close monitoring by a healthcare professional (15,9166,97770,104266). The safety of lithium supplements during pregnancy is unknown.
LACTATION: LIKELY UNSAFE
when used orally.
Lithium is secreted into breast milk and may cause adverse effects in the nursing infant (15). Prescription lithium may be used in circumstances when the potential maternal benefits outweigh the possible risk to the infant. The infant should be closely monitored for signs of lithium toxicity (97770).

Theoretically, high doses of folic acid might increase the toxicity of 5-fluorouracil.
Details
Increases in gastrointestinal side effects of 5-fluorouracil, such as stomatitis and diarrhea, have been described in two clinical studies when leucovorin, a form of folic acid, was administered with 5-fluorouracil (16845).
|
Use of high-dose folic acid might contribute to capecitabine toxicity.
Details
Clinical research suggests that higher serum folate levels are associated with an increased risk for moderate or severe toxicity during capecitabine-based treatment for colorectal cancer (105402). Additionally, in one case report, taking folic acid 15 mg daily might have contributed to increased toxicity, including severe diarrhea, vomiting, edema, hand-foot syndrome, and eventually death, in a patient prescribed capecitabine (16837).
|
Folic acid might reduce the efficacy of methotrexate as a cancer treatment when given concurrently.
Details
Methotrexate exerts its cytotoxic effects by preventing conversion of folic acid to the active form needed by cells. There is some evidence that folic acid supplements reduce the efficacy of methotrexate in the treatment of acute lymphoblastic leukemia, and theoretically they could reduce its efficacy in the treatment of other cancers (9420). Advise cancer patients to consult their oncologist before using folic acid supplements. In patients treated with long-term, low-dose methotrexate for rheumatoid arthritis (RA) or psoriasis, folic acid supplements can reduce the incidence of side effects, without reducing efficacy (768,2162,4492,4493,4494,4546,9369).

Folic acid might have antagonistic effects on phenobarbital and increase the risk for seizures.
Details
|
Folic acid might reduce serum levels of phenytoin in some patients.
Details
Folic acid may be a cofactor in phenytoin metabolism (4471). Folic acid, in doses of 1 mg daily or more, can reduce serum levels of phenytoin in some patients (4471,4477,4531,4536). Increases in seizure frequency have been reported. If folic acid supplements are added to established phenytoin therapy, monitor serum phenytoin levels closely. If phenytoin and folic acid are started at the same time and continued together, adverse changes in phenytoin pharmacokinetics are avoided (4471,4472,4473,4531). Note that phenytoin also reduces serum folate levels.

Folic acid might have antagonistic effects on primidone and increase the risk for seizures.
Details
|
Folic acid might antagonize the effects of pyrimethamine.
Details
Folic acid can antagonize the antiparasitic effects of pyrimethamine against toxoplasmosis and Pneumocystis carinii pneumonia. Folic acid doesn't antagonize the effects of pyrimethamine in the treatment of malaria, because malarial parasites cannot use exogenous folic acid. Use folinic acid as an alternative to folic acid when indicated (9380).

Theoretically, taking lithium supplements with ACEIs might increase levels and adverse effects of lithium.
Details
|
Theoretically, taking lithium supplements with anticonvulsants might increase the risk of neurotoxicity.
Details
|
Theoretically, taking lithium supplements with antipsychotic drugs might increase the risk of encephalopathic syndrome.
Details
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 (97770). It is unclear if this interaction would occur with the smaller doses found in lithium supplements.
|
Theoretically, taking lithium supplements with calcium channel blockers might reduce lithium levels and might also increase the risk of certain adverse effects.
Details
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 (9,15). It is unclear if these interactions would occur with the smaller doses found in lithium supplements.
|
Theoretically, taking lithium supplements with loop diuretics might increase lithium levels and adverse effects.
Details
Thiazide diuretics and loop diuretics might reduce lithium excretion, particularly in sodium-restricted patients (9,15). 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 (97770). It is unclear if this interaction would be clinically significant with the smaller doses found in lithium supplements.
|
Theoretically, taking lithium supplements with methyldopa might increase the risk of lithium toxicity.
Details
Concurrent use of methyldopa with lithium increases the risk of lithium toxicity (9). It is unclear if this interaction would be clinically significant with the smaller doses found in lithium supplements.
|
Theoretically, taking lithium supplements with methylxanthines might decrease lithium levels.
Details
|
Theoretically, taking lithium supplements with NSAIDs might increase lithium levels and adverse effects.
Details
|
Theoretically, taking lithium supplements with phenothiazines might decrease the levels and clinical effects of phenothiazines.
Details
|
Theoretically, taking lithium supplements with serotonergic drugs might both mask and increase the risk of serotonin syndrome.
Details
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 (105343). Lithium can increase serotonin levels (9,15), 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.
|
Theoretically, taking lithium supplements with skeletal muscle relaxants might prolong neuromuscular blockade.

Below is general information about the adverse effects of the known ingredients contained in the product Lithium Orotate. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, folic acid is generally well-tolerated in amounts found in fortified foods, as well as in supplemental doses of less than 1 mg daily.
Most Common Adverse Effects:
Orally: At doses of 5 mg daily - abdominal cramps, diarrhea, and rash. At doses of 15 mg daily - bitter taste, confusion, hyperactivity, impaired judgment, irritability, nausea, sleep disturbances.
Serious Adverse Effects (Rare):
Orally: Cancer (long-term use), cardiovascular complications, liver injury, seizures.
All ROAs: Allergic reactions such as bronchospasm and anaphylactic shock.
Cardiovascular ...There is some concern that high oral doses of folic acid might increase the risk of adverse cardiovascular outcomes. Clinical research shows that taking doses of 800 mcg to 1.2 mg/day might increase the risk of adverse cardiovascular events in patients with cardiovascular disease (12150,13482). High doses of folic acid might promote cell growth by providing large amounts of the biochemical precursors needed for cell replication. Overgrowth of cells in the vascular wall might increase the risk of occlusion (12150). Although some research suggests that use of folic acid might increase the need for coronary revascularization, analysis of multiple studies suggests that taking folic acid up to 5 mg/day for up to 24 months does not appear to affect coronary revascularization risk (90798).
Dermatologic ...Orally, folic acid 1-5 mg daily can cause rash (7225,90375,91319). Folic acid 15 mg daily can sometimes cause allergic skin reactions (15).
Gastrointestinal ...Orally, folic acid 5 mg daily can cause abdominal cramps and diarrhea (7225). Folic acid 15 mg daily can sometimes cause nausea, abdominal distention, flatulence, and bitter taste in the mouth (15). In children aged 6-30 months at risk of malnourishment, taking a nutritional supplement (Nutriset Ltd) enriched in folic acid 75-150 mcg daily, with or without vitamin B 12 0.9-1.8 mcg daily, for 6 months increases the likelihood of having persistent diarrhea (90391).
Hepatic ...Liver dysfunction, with jaundice and very high liver enzymes, occurred in a 30-year-old pregnant patient with severe nausea and vomiting taking a folic acid supplement (Folic acid, Nature Made) 400 mcg daily. Based on the timing of ingestion, the lack of other etiological factors, a positive drug-induced lymphocyte stimulation test, and liver function normalization once the folic acid had been stopped, the authors suggest the folic acid supplement was the cause. However, the authors did not determine which substance in the folic acid supplement was responsible and therefore it cannot be determined that folic acid itself was the cause (91309).
Neurologic/CNS ...Orally, folic acid 15 mg daily can sometimes cause altered sleep patterns, vivid dreaming, irritability, excitability, hyperactivity, confusion, and impaired judgment (15). Large doses of folic acid can also precipitate or exacerbate neuropathy in people deficient in vitamin B12 (6243). Use of folic acid for undiagnosed anemia has masked the symptoms of pernicious anemia, resulting in lack of treatment and eventual neurological damage (15). Patients should be warned not to self-treat suspected anemia. There is also some concern that consuming high amounts of folic acid from the diet and/or supplements might worsen cognitive decline in older people. A large-scale study suggests that people over 65 years of age, who consume large amounts of folic acid (median of 742 mcg/day), have cognitive decline at a rate twice as fast as those consuming smaller amounts (median of 186 mcg/day). It's not known if this is directly attributable to folic acid. It is theorized that it could be due to folic acid masking a vitamin B12 deficiency. Vitamin B12 deficiency is associated with cognitive decline (13068). More evidence is needed to determine the significance of this finding. For now, suggest that most patients aim for the recommended folic acid intake of 400 mcg/day.
Oncologic
...There is some concern that high dose folic acid might increase the risk of cancer, although research is unclear and conflicting.
A large-scale population study suggests that taking a multivitamin more than 7 times per week with a separate folic acid supplement significantly increased the risk of prostate cancer (15607). Clinical research also shows that taking folic acid 1 mg daily increase the absolute risk of prostate cancer by 6.4% over a 10-year period when compared with placebo. However, those with a higher baseline dietary intake of folic acid had a lower rate of prostate cancer, but this was not statistically significant. Also, folate and folic acid intake in patients with prostate cancer is not associated with the risk of prostate cancer recurrence after radical prostatectomy (91317). However, it is possible that discrepancies are due to dietary folate versus folic acid intake. Large analyses of population studies suggest that while dietary folate/folic acid is not associated with prostate cancer, high blood folate/folic acid increases the risk of prostate cancer (50411,91316).
Additional clinical research shows that taking folic acid 800 mcg daily, in combination with vitamin B12 400 mcg, significantly increases the risk of developing cancer, especially lung cancer, and all-cause mortality in patients with cardiovascular disease (17041). However, this may be due to vitamin B12, as other observational research found that higher vitamin B12 levels are linked with an increased risk for lung cancer (102383). Meta-analyses of large supplementation trials of folic acid at levels between 0.5-2.5 mg daily also suggest an increased risk of cancer (50497,110318). Also, in elderly individuals, taking folic acid 400 mcg daily with vitamin B12 500 mcg daily increased the risk of cancer. The risk was highest in individuals over 80 years of age and in females and mainly involved gastrointestinal and colorectal cancers (90393).
Not all researchers suspect that high intake of folic acid supplements might be harmful. Some research suggests that increased dietary intake of folic acid, along with other nutrients, might be protective against cancer (16822). A meta-analysis of multiple clinical trials suggests that folic acid supplementation studies with folic acid levels between 500 mcg to 50 mg/day does not increase the risk of general or site-specific cancer for up to 7 years (91312,91321). Also, a post-hoc subgroup analysis of results from clinical research in adults with a history of recent stroke or ischemic attack suggests that taking folic acid, vitamin B12, and vitamin B6 does not increase cancer risk overall, although it was associated with an increased risk of cancer in patients who also had diabetes (90378).
Psychiatric ...Orally, folic acid 15 mg daily can sometimes cause exacerbation of seizure frequency and psychotic behavior (15).
Pulmonary/Respiratory ...Folic acid use in late pregnancy has been associated with an increased risk of persistent and childhood asthma at 3. 5 years in population research (50380). When taken pre-pregnancy or early in pregnancy, population research has not found an association with increased risk of asthma or allergies in childhood (90799,103979). Folic acid use in pregnancy has been associated with a slightly increased risk of wheeze and lower respiratory tract infections up to 18 months of age in population research (50328).
General
...Orally, prescription forms of lithium are generally well tolerated when used as prescribed.
Plasma levels must be monitored to avoid toxicity. It is unclear how the lower doses of lithium found in supplements may alter the occurrence and likelihood of these adverse effects.
Most Common Adverse Effects:
Orally: Edema, fatigue, fine tremor, gastrointestinal symptoms, lethargy, muscle weakness, polydipsia, polyuria, skin conditions, vertigo, and weight gain.
Cardiovascular ...Orally, lithium has been reported to cause bradyarrhythmia. A case of symptomatic bradycardia due to sinoatrial node dysfunction is reported in a patient with bipolar disorder who took lithium orotate 20 mg daily for 5 years, despite a serum lithium level in the therapeutic range (111327). Deep vein thrombosis is also reported in 2 patients with bipolar disorder who experienced toxic serum levels of lithium (111329). It is unclear if these effects are a concern with the smaller doses found in lithium supplements.
Dermatologic ...Orally, lithium can cause or exacerbate skin disorders such as hair loss, acne, psoriasis, and rash (9,15,97770). A case of Stevens-Johnson syndrome is also reported in a patient with bipolar disorder who took lithium carbonate at an unknown dose for 17 days (111317).
Endocrine ...Orally, chronic use of lithium has been reported to cause various endocrine disorders. Case reports associate chronic lithium use with hypothyroidism, hyperthyroidism, goiter, hyperparathyroidism, and diabetes insipidus (9,15,104267,104269,104270,104271,111320). In one case report, a 68-year-old male with schizophrenia developed severe hypothyroidism resulting in myxedema coma after taking oral lithium carbonate. He recovered after discontinuation of lithium and administration of levothyroxine. At least two other cases of lithium-associated myxedema coma have been reported (97740). At least 4 cases of lithium-associated hyperparathyroidism have been reported in females aged 53-68 years that had taken lithium for 24 years or more. These patients presented with hypernatremia, hypercalcemia, elevated serum creatinine, thyroid or parathyroid abnormalities, and nephrogenic diabetes insipidus (104269,105344). It is unclear if these effects are a concern with the smaller doses found in lithium supplements.
Gastrointestinal ...Orally, lithium can cause gastrointestinal symptoms. These adverse effects often improve with continued use (9). It is unclear if this effect would occur with the smaller doses found in lithium supplements.
Musculoskeletal ...Orally, lithium can cause muscle weakness. This adverse effect often improves with continued use (9). It is unclear if this effect would occur with the smaller doses found in lithium supplements.
Neurologic/CNS ...Orally, lithium can cause vertigo, muscle weakness, lethargy, fatigue, and a dazed feeling. These adverse effects often improve with continued use. Fine tremor can occur and may persist with continued use. Chronic use of lithium can cause mild cognitive and memory impairment, particularly in the presence of dehydration or hyponatremia (9,15,97745). These long-term neurological adverse effects of lithium are potentially due to accumulation in the central nervous system even when blood levels appear within the therapeutic range (97745). Lithium-associated hyperparathyroidism-induced hypercalcemia has resulted in hallucinations, confusion, insomnia, and agitation (105344). A case of delirium and transient difficulty with word finding is reported in a patient with bipolar disorder treated with lithium 250-500 mg twice daily and 9 sessions of electroconvulsive therapy (111316). A case of mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is also reported in a patient with bipolar disorder who had a toxic lithium level of 1.94 mEq/L (111318). It is unclear if these effects would occur with the smaller doses found in lithium supplements.
Psychiatric ...Abrupt discontinuation of lithium resulting in a rapid reduction in serum lithium levels can precipitate recurrence of bipolar symptoms (9165). Lithium should be tapered gradually over at least 14 days (9165).
Renal ...Orally, lithium can cause polyuria, polydipsia, and edema (9). Chronic lithium use has been reported to cause central or nephrogenic diabetes insipidus, hypocalciuric hypercalcemia, and nephrotic syndrome (104269,104271,111314,111319). Long-term lithium use is estimated to increase the odds of chronic kidney disease (CKD) by at least 2-fold and may contribute to CKD progression (111315,111324). It is unclear if these effects would occur with the smaller doses found in lithium supplements.
Other ...Orally, chronic use of lithium has been reported to cause an irreversible reduction in taste and smell in a patient with bipolar disorder who took 400-1000 mg/day for 4 months (111313). Chronic use of lithium 1200 mg/day has also been reported to cause dysphagia in a 17-year-old patient with bipolar disorder; however, the patient's serum lithium level was in the toxic range and the adverse effect resolved once the level normalized (111328). It is unclear if these effects would occur with the smaller doses found in lithium supplements.
