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.

Brain Fuel Grape Flavored contains four active ingredients. Vitamin B6 supports nerve and immune function and is proven effective for vitamin B6 deficiency and certain rare anemias.

Sodium is an electrolyte your body needs in small amounts to balance fluids and nerve signals. Vitamin B12 is essential for nerve function and red blood cell formation and is effective for B12 deficiency.

Cognigrape is a grape extract studied for circulation and vein health, though evidence is limited. The product also contains inactive ingredients—glucose syrup, cane sugar, water, pectin, citric acid, natural flavors, sodium citrate, coconut oil, sunflower lecithin, and beeswax—which serve as sweeteners, thickeners, and binders.

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: support short-term memory and concentration.
  • We looked for evidence on: Attention, Cognitive function, Cognitive impairment, mental performance, focus.
  • The closest evidence on file: Vitamin B12 is rated "Possibly Ineffective" for Cognitive impairment (Natural Medicines).
  • Also on file: Grape is rated "Insufficient Reliable Evidence To Rate" for Attention deficit-hyperactivity disorder (ADHD), Cognitive function, Cognitive impairment.
  • Also on file: Vitamin B12 is rated "Insufficient Reliable Evidence To Rate" for Cognitive function, Attention.

The evidence for this product's ingredients is mixed. Vitamin B6 is proven effective for vitamin B6 deficiency and sideroblastic anemia, and possibly effective for pregnancy-related nausea and high homocysteine levels.

Vitamin B12 is proven effective for B12 deficiency. Cognigrape (grape extract) is possibly effective for chronic venous insufficiency (poor circulation in the legs) but was found possibly ineffective for chemotherapy-related nausea, hay fever, and weight loss in the studies we have data on.

Sodium has no established effectiveness ratings in our data. Overall, if you're taking this for general brain health, the evidence in our records doesn't establish that claim.

The evidence, ingredient by ingredient Vitamin B6 Sodium Vitamin B12 Grape

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 generally well tolerated in doses under 100 mg daily, though high doses over time can damage nerves. It's often used for morning sickness under medical guidance.

Sodium is safe at normal dietary amounts but too much raises blood pressure and strains your heart—avoid supplements unless your doctor says otherwise. Vitamin B12 is very safe; your body removes excess in urine, so there's no upper limit.

Cognigrape (grape extract) appears generally well tolerated; whole grapes are safe for most people. The most common side effects across these ingredients are mild: abdominal pain, nausea, headache, and diarrhea.

Serious adverse effects are rare but include nerve damage from very high B6 doses and allergic reactions to grape.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 4 of the 4 matched ingredients can interact with medications — Grape, Vitamin B12, Vitamin B6, Sodium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; lithium; Parkinson's medications.
  • For scale: 1,085 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Brain Fuel Grape Flavored, double-check these medication types with your pharmacist: blood pressure medications and seizure drugs (vitamin B6 can interfere); lithium and corticosteroids (sodium interactions); blood thinners and antiplatelet drugs (grape may increase bleeding risk); and cyclosporine (grape can reduce its absorption by up to 30%). If you take metformin, note that B12 may slightly affect its absorption.

Separately time grape juice and cyclosporine by at least 2 hours if both are needed.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help if you're deficient in B6 or B12, or if you're looking into grape extract for circulation. If you take any prescription medication—especially blood pressure drugs, seizure meds, lithium, blood thinners, or cyclosporine—talk to your pharmacist or doctor before starting.

The sodium content is worth noting if you're managing high blood pressure or heart disease.

Cognigrape9 drug types · 910 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, grape extracts may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that grape extracts might decrease platelet aggregation.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Ingesting grape juice with cyclosporine can reduce cyclosporine absorption.
A small pharmacokinetic study in healthy young adults shows that intake of purple grape juice 200 mL along with cyclosporine can decrease the absorption of cyclosporine by up to 30% when compared with water. Separate doses of grape juice and cyclosporine by at least 2 hours to avoid this interaction.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, grape juice might reduce the levels of CYP1A2 substrates.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of CYP1A2.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, grape seed extract may increase the levels of CYP2D6 substrates.
In vitro evidence suggests that grape seed extract might inhibit CYP2D6 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, grape seed extract might increase the levels of CYP2E1 substrates.
In vitro and animal research suggests that grape seed proanthocyanidin extract inhibits CYP2E1 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

It is unclear if grape seed extract inhibits or induces CYP3A4; research is conflicting.
In vitro evidence suggests that grape seed extract might inhibit CYP3A4 enzymes. However, evidence from animal research shows that grape seed extract may induce CYP3A4 in the liver. So far, these interactions have not been reported in humans.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, long-term intake of grape seed extract might decrease the effects of midazolam.
Animal research shows that subchronic ingestions of grape seed extract can increase the elimination of intravenous midazolam by increasing hepatic CYP3A4 activity. Single doses of grape seed extract do not appear to affect midazolam elimination.

Likelihood Possible Evidence D
Phenacetin

Grape juice might decrease phenacetin absorption.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of cytochrome P450 1A2 (CYP1A2).

Likelihood Possible Evidence B
Cytochrome P450 2C9 (Cyp2C9) Substrates

It is unclear if grape juice or grape seed extract inhibits CYP2C9; research is conflicting.
In vitro evidence shows that grape seed extract or grape juice might inhibit CYP2C9 enzymes. However, a small pharmacokinetic study in healthy adults shows that drinking 8 ounces of grape juice once does not affect the clearance of flurbiprofen, a probe-drug for CYP2C9 metabolism. The effects of continued grape juice consumption are unclear.

Likelihood Unlikely Evidence D
Cognigrape 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

Sodium7 drug types · 205 drugs

Antihypertensive Drugs

Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.

Likelihood Probable Evidence A
Corticosteroids

Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.

Likelihood Possible Evidence D
Didanosine (Videx)

Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.

Likelihood Probable Evidence C
Lithium

Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.

Likelihood Probable Evidence B
Sodium Phosphates

Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Sodium-Containing Drugs

Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Tolvaptan (Samsca)

Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.

Likelihood Probable Evidence C
Sodium 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.

Brain Fuel Grape Flavored by Nature's Way: Common Questions

Does Brain Fuel Grape Flavored by Nature's Way interact with any medications?
Yes. Based on its ingredients, Brain Fuel Grape Flavored has a known interaction with 1,084 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Brain Fuel Grape Flavored 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.
Is this safe to take if I'm pregnant?
The safety data on the individual ingredients is mixed. Vitamin B6 is listed as both Likely Safe and Possibly Unsafe in pregnancy, so you'd need to discuss dosage and your specific situation with your doctor. Vitamin B12 and grape are considered likely safe in pregnancy at normal amounts. Sodium safety in pregnancy is also unclear. This is a personalized decision—check with your OB or pharmacist before starting.
Can I take this while breastfeeding?
Vitamin B12 is considered safe during breastfeeding. Vitamin B6 at recommended levels is typically used for postpartum support. Sodium at normal dietary amounts is fine. However, we don't have enough data on concentrated grape supplements while nursing, so talk with your healthcare provider to be sure.
What is Cognigrape, and what does it do?
Cognigrape is a grape seed extract used in this product. It's been studied mainly for chronic venous insufficiency—poor circulation in the legs. The evidence shows it's possibly effective for that condition, though it hasn't proven helpful for nausea, allergies, or weight loss in the studies we have data on.
Will this really help my brain?
The ingredients here—B6, B12, sodium, and grape extract—don't have proven effectiveness for general brain health in our data. B12 is essential for nerve function and effective if you're deficient, and B6 supports similar roles. If you're looking for brain support, your best bet is ensuring you're not deficient in these nutrients; talk to your doctor about whether testing or supplementation makes sense for you.
Are there any common side effects?
Most people tolerate these ingredients well. The most common side effects reported are mild: abdominal pain, nausea, headache, diarrhea, dry mouth, and heartburn. Serious side effects are rare. High doses of vitamin B6 over time can cause nerve damage, and grape allergies, though uncommon, can trigger anaphylaxis.
Why does this have sodium in it if it's a brain supplement?
Sodium is added as an ingredient (sodium citrate is listed in the inactive ingredients), likely for flavoring or preservation. Your body does need some sodium, but this product isn't a primary source, and the amount in a gummy is generally small. If you're watching sodium intake for blood pressure or heart health, check the nutrition label for the exact amount per serving.
