HelloPharmacist Scorecard of B12 Energy Ginger by MegaFood
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
B12 Energy Ginger contains two active ingredients: vitamin B12 and organic ginger. These are mixed into a gummy or jelly base with inactive ingredients like tapioca syrup, cane sugar, pectin, and beet root powder.
Does it work?
Not established
Vitamin B12 is effective for treating B12 deficiency and a genetic condition called Imerslund-Grasbeck disease, and it's considered likely effective for cyanide poisoning. The data shows it may help with canker sores and a type of nerve pain called postherpetic neuralgia, though the evidence is still limited.
For ginger, the research is mixed: it's possibly effective for pregnancy-related nausea and vomiting, period pain (dysmenorrhea), and osteoarthritis, but the evidence is weaker for muscle soreness from exercise and chemotherapy nausea.
How safe is it?
Well-documented data
Vitamin B12 is generally very well tolerated and has no established upper limit since your body clears the excess through urine. It's needed and considered safe during pregnancy and breastfeeding at normal recommended amounts — follow your provider's guidance.
Ginger is also generally well tolerated in typical food and supplement amounts for most healthy adults, though at higher doses (5 grams per day or more) the risk of side effects goes up. You might notice mild stomach upset like abdominal discomfort, burping, heartburn, or diarrhea, especially with higher doses.
Rarely, ginger has caused a mild heart rhythm change in one trial participant. Since ginger is often used for morning sickness, talk with your doctor first and keep amounts moderate if you're pregnant.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you take blood thinners (anticoagulants like warfarin or phenprocoumon) — ginger may increase your bleeding risk. Also double-check if you're on diabetes medications, as ginger may lower your blood sugar further.
Let your pharmacist know about any heart drugs like nifedipine or losartan, any cancer medications, or any drugs your liver breaks down through the CYP3A4 pathway. If you take metformin for diabetes, your B12 levels are already at risk and supplementing may help, but still talk it through with your provider.
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 can be useful for someone who wants B12 support and may benefit from ginger's effects on nausea or joint pain — but it's not a product to start without checking your medications first. If you take blood thinners, diabetes drugs, heart medications, or cancer treatments, you need to clear this with your pharmacist before adding it to your routine.

B12 Energy Ginger by MegaFood Drug Interactions
HelloPharmacist Interaction Report
MegaFood's B12 Energy Ginger contains two active ingredients, and the ginger component has documented interactions with a number of medications.
The most serious concern is with blood thinners (anticoagulants) like warfarin and phenprocoumon — ginger may increase bleeding risk by thinning your blood further. There's also a case report of ginger raising INR (a measure of how thin your blood is) in someone taking phenprocoumon.
Read the full breakdown — every affected drug type, severity by severity
Ginger interacts with several other drug types at moderate severity. It may increase the risk of low blood sugar (hypoglycemia) if you're on diabetes medications, and it can theoretically boost losartan levels and lower your blood pressure more than intended.
Ginger may also interact with certain cancer drugs and other medications that your liver processes through a specific enzyme (CYP3A4 substrates), as well as drugs your body pumps out via a protein called P-glycoprotein — either increasing or decreasing how much gets into your bloodstream.
Vitamin B12 has one documented interaction: metformin, a diabetes medication, may lower your B12 levels over time because it can interfere with how your body absorbs this vitamin from food and supplements.
Altogether, these interactions span 993 individual medications. If you take any prescription drugs — especially blood thinners, diabetes medications, heart drugs, or cancer treatments — run them through the medication checker below before starting this product.

For each ingredient in B12 Energy Ginger 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.
organic Ginger
Anticoagulant/Antiplatelet Drugs
Ginger may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Laboratory research suggests that ginger inhibits thromboxane synthetase and decreases platelet aggregation. However, this has not been demonstrated unequivocally in humans, with mixed results from clinical trials. Theoretically, excessive amounts of ginger might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
Antidiabetes Drugs
Theoretically, taking ginger with antidiabetes drugs might increase the risk of hypoglycemia.
Animal and human research suggests that ginger might increase insulin levels and/or decrease blood glucose levels.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction has not been reported in humans.
Losartan (Cozaar)
Theoretically, ginger might increase levels of losartan and the risk of hypotension.
In animal research, ginger increased the levels and hypotensive effects of a single dose of losartan. It is not clear if ginger alters the concentration or effects of losartan when taken continuously. Additionally, this interaction has not been shown in humans.
Nifedipine (Procardia)
Ginger may have antiplatelet effects and increase the risk of bleeding if used with nifedipine.
Clinical research shows that combined treatment with ginger 1 gram plus nifedipine 10 mg significantly inhibits platelet aggregation when compared to nifedipine or ginger alone.
P-Glycoprotein Substrates
Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Phenprocoumon (Marcoumar, Others)
Ginger might increase the risk of bleeding with phenprocoumon.
Phenprocoumon, a warfarin-related anticoagulant, might increase the international normalized ratio (INR) when taken with ginger. There is one case report of a 76-year-old woman with a stable INR on phenprocoumon that increased to greater than 10 when she began consuming dried ginger and ginger tea.
Warfarin (Coumadin)
Ginger might increase the risk of bleeding with warfarin.
Laboratory research suggests that ginger might inhibit thromboxane synthetase and decrease platelet aggregation. In one case report, ginger increased the INR when taken with phenprocoumon, which has similar pharmacological effects as warfarin. In another case report, ginger increased the INR when taken with a combination of warfarin, hydrochlorothiazide, and acetaminophen. A longitudinal analysis suggests that taking ginger increases the risk of bleeding in patients taking warfarin for at least 4 months. However, research in healthy people suggests that ginger has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin. Until more is known, monitor INRs closely in patients taking large amounts of ginger.
Calcium Channel Blockers
Theoretically, taking ginger with calcium channel blockers might increase the risk of hypotension.
Some animal and in vitro research suggests that ginger has hypotensive and calcium channel-blocking effects. Another animal study shows that concomitant administration of ginger and the calcium channel blocker amlodipine leads to greater reductions in blood pressure when compared with amlodipine alone.
Cyclosporine (Neoral, Sandimmune)
Theoretically, when taken prior to cyclosporine, ginger might decrease cyclosporine levels.
In an animal model, ginger juice taken 2 hours prior to cyclosporine administration reduced the maximum concentration and area under the curve of cyclosporine by 51% and 40%, respectively. This effect was not observed when ginger juice and cyclosporine were administered at the same time.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, ginger might increase the levels of CYP2B6 substrates.
In vitro research shows that ginger inhibits CYP2B6 activity. However, this interaction has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, ginger might increase the levels of CYP2C9 substrates.
In vitro research shows that ginger inhibits CYP2C9 activity. However, this interaction has not been reported in humans.
Metronidazole (Flagyl)
Theoretically, ginger might increase levels of metronidazole.
In an animal model, ginger increased the absorption and plasma half-life of metronidazole. In addition, the elimination rate and clearance of metronidazole was significantly reduced.
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.
