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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Neuro Complex contains four active ingredients: vitamin B6, vitamin B12, thiamine (vitamin B1), and alpha-lipoic acid. These are B vitamins and an antioxidant compound that play roles in nerve function, energy metabolism, and cellular protection.

The tablet also contains several inactive ingredients—microcrystalline cellulose, stearic acid, pharmaceutical glaze, croscarmellose sodium, silicon dioxide, and magnesium stearate—which are common binders and flow agents used to hold the tablet together and aid manufacturing.

Does it work?

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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Nerve and brain function support.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease), Attention, Attention deficit-hyperactivity disorder (ADHD), Carpal tunnel syndrome — and 4 related terms.
  • The closest evidence on file: Alpha-lipoic Acid is rated "Possibly Ineffective" for HIV/AIDS-related dementia (Natural Medicines).
  • Also on file: Vitamin B12 is rated "Possibly Ineffective" for Age-related cognitive decline, Alzheimer disease, Cognitive impairment.
  • Also on file: Vitamin B6 is rated "Possibly Ineffective" for Age-related cognitive decline, Alzheimer disease, Carpal tunnel syndrome.

The evidence for what this product does depends on which condition you're considering. Vitamin B6 is effective for sideroblastic anemia and B6 deficiency, likely effective for high homocysteine levels, and possibly effective for pregnancy-related nausea.

Vitamin B12 is effective for B12 deficiency and a rare absorption disorder called Imerslund-Grasbeck disease, and possibly effective for canker sores and nerve pain after shingles. Thiamine is effective for thiamine deficiency and Wernicke-Korsakoff syndrome (a serious brain condition from severe B1 deficiency).

Alpha-lipoic acid is only possibly effective for diabetic nerve damage, high cholesterol, and weight management—the evidence is limited. The product's overall effectiveness for a "neuro complex" purpose isn't established in the data we hold.

The evidence, ingredient by ingredient Vitamin B6 Vitamin B12 Thiamine Alpha-lipoic Acid

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B6 is well tolerated in doses under 100 mg daily, but high doses over time can damage nerves (sensory neuropathy); this risk rises sharply above 1,000 mg daily or with cumulative doses of 1 gram or more, though it can happen at lower doses too. Common side effects include headache, nausea, and heartburn.

Vitamin B12 is generally very safe and well tolerated with no established upper limit—excess is removed in your urine. Thiamine is very safe by mouth in normal amounts and is needed in pregnancy and breastfeeding.

Alpha-lipoic acid is generally well tolerated but can lower blood sugar and is best used under medical guidance; safety data for pregnancy and breastfeeding are insufficient, so the safety information advises against use during these times. Common side effects with alpha-lipoic acid include headache, nausea, and heartburn.

Alpha-Lipoic Acid5 drug types · 263 drugs

Alkylating Agents

Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of alkylating agents.
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy. Advise patients to consult their oncologist before using alpha-lipoic acid.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, alpha-lipoic acid may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro, alpha-lipoic acid inhibits platelet aggregation.

Likelihood Possible Evidence D
Antitumor Antibiotics

Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of antitumor antibiotics.
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of antitumor antibiotic drugs, which work by generating free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy involving antitumor antibiotics. Advise patients to consult their oncologist before using alpha-lipoic acid.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, alpha-lipoic acid might decrease the effects of thyroid hormone drugs.
Animal research suggests that co-administration of thyroxine with alpha-lipoic acid reduces conversion into the active T3 form.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking alpha-lipoic acid with antidiabetes drugs might increase the risk of hypoglycemia.
Although some small clinical studies have suggested that alpha-lipoic acid can lower blood glucose levels, larger clinical studies in patients with diabetes have shown no clinically meaningful effect. Additionally, co-administration of single doses of alpha-lipoic acid and glyburide or acarbose did not cause detectable drug interactions in healthy volunteers.

Likelihood Unlikely Evidence B
Alpha-Lipoic Acid full monograph & interactions

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

Likelihood Unlikely Evidence D
Vitamin B6 full monograph & interactions

Vitamin B121 drug type · 20 drugs

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.

Likelihood Possible Evidence A
Vitamin B12 full monograph & interactions

Thiamine1 drug type · 3 drugs

Trimethoprim (Proloprim)

Trimethoprim might increase blood levels of thiamine.
In vitro, animal, and clinical research suggest that trimethoprim inhibits intestinal thiamine transporter ThTR-2, hepatic transporter OCT1, and renal transporters OCT2, MATE1, and MATE2, resulting in paradoxically increased thiamine plasma concentrations.

Neuro Complex by Mason Natural: Common Questions

Does Neuro Complex by Mason Natural interact with any medications?
Yes. Based on its ingredients, Neuro Complex has a known interaction with 470 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Neuro Complex contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 pregnant?
The B vitamins in this product (B6, B12, and thiamine) have varying safety data in pregnancy—thiamine is considered safe at recommended amounts, but alpha-lipoic acid data aren't sufficient, and the product advises against it during pregnancy. Talk with your doctor or pharmacist about whether this specific product is right for you, since it's a personalized decision.
Can I take this if I'm breastfeeding?
Vitamin B12 and thiamine are needed while breastfeeding and are safe at recommended amounts. Alpha-lipoic acid doesn't have enough safety information for breastfeeding, and the data advise against it. Speak with your provider about whether this product fits your situation.
What are the most common side effects?
The most common side effects are headache, nausea, heartburn, and loss of appetite. These typically happen with vitamin B6 and alpha-lipoic acid. Most people tolerate standard doses well, but if you notice these effects, let your pharmacist or doctor know.
What is alpha-lipoic acid for?
Alpha-lipoic acid is an antioxidant compound. In this product it's likely included for its possible effects on diabetic nerve pain, cholesterol levels, and weight management, though the evidence is limited. It's not a vitamin—your body can make small amounts on its own.
Is this safe for high doses over a long time?
Vitamin B6 is the main concern: high doses over time can damage nerves, especially above 1,000 mg daily. The other B vitamins are very safe even at higher amounts. If you're considering long-term use, check the label for the actual dose of each ingredient and talk with your pharmacist.
Can this lower my blood sugar?
Alpha-lipoic acid may lower blood sugar, which is why it's used for diabetic nerve pain. If you take diabetes medications, this adds a small risk of low blood sugar (hypoglycemia), so check with your pharmacist before starting.
