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 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This lozenge contains five active ingredients. Vitamin B12 is the primary nutrient and plays a key role in nerve function and red blood cell formation.

The other four active ingredients are herbal: dandelion (a leafy green often eaten as food), red raspberry leaf, beet, and sarsaparilla. The product also contains inactive ingredients—cane sugar, fructose, citric acid, natural flavors, acacia gum, silica, beet juice, magnesium stearate, stearic acid, and stevia—which serve as sweeteners, flavorings, and tablet binders.

Does it work?

Strong evidence
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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Imerslund-Grasbeck disease — rated "Effective" (Vitamin B12) (Natural Medicines).
  • On file: Vitamin B12 deficiency — rated "Effective" (Vitamin B12) (Natural Medicines).
  • On file: Cyanide poisoning — rated "Likely Effective" (Vitamin B12) (Natural Medicines).
  • On file: Athletic performance — rated "Possibly Effective" (Beet) (Natural Medicines).
  • On file: Exercise-induced muscle soreness — rated "Possibly Effective" (Beet) (Natural Medicines).

Vitamin B12 is rated Effective for B12 deficiency and a rare absorption disorder called Imerslund-Grasbeck disease, and Likely Effective for cyanide poisoning. It's Possibly Effective for canker sores and postherpetic neuralgia (a nerve pain that can follow shingles).

The herbal ingredients—dandelion, raspberry, beet, and sarsaparilla—lack sufficient evidence to establish their effectiveness for any condition in the data we hold. Beet alone is rated Possibly Effective for athletic performance and exercise muscle soreness, and Possibly Ineffective for COPD.

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B12 is generally very well tolerated and has no established upper limit because your body removes excess through the urine. It's considered safe at recommended amounts in pregnancy and breastfeeding.

The herbal ingredients are less studied at supplement doses. Dandelion is generally well tolerated as food but may cause diarrhea, heartburn, or stomach discomfort at higher doses; rare allergic reactions including anaphylaxis are possible, especially in people sensitive to ragweed and related plants.

Red raspberry leaf is generally well tolerated but may cause diarrhea or stomach upset. Beet is safe as food and generally well tolerated; at supplement doses, watch for red or black stools (harmless) and rare kidney issues with large amounts.

Sarsaparilla has limited human safety data; avoid it in pregnancy and while breastfeeding due to insufficient information.

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?
  • 5 of the 5 matched ingredients can interact with medications — Beet, Red Raspberry, Sarsaparilla, Dandelion, Vitamin B12.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 1,071 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 this product, double-check with your pharmacist if you take blood thinners or antiplatelet drugs (dandelion and raspberry leaf raise bleeding risk); potassium-sparing diuretics (dandelion may raise potassium too high); diabetes or insulin medications (dandelion and raspberry leaf may lower blood sugar); digoxin or other heart medications (sarsaparilla may increase toxicity); lithium (dandelion and sarsaparilla may raise levels); or metformin (may affect B12 absorption). These are Moderate and Minor severity interactions, so review is important.

Each ingredient & the kinds of drugs it affects

For each ingredient in Vitamin B12 Herbal Lozenges Raspberry Flavor 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.

Beet3 drug types · 861 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Likelihood Possible Evidence D
Antihypertensive Drugs

Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.

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

Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.

Likelihood Possible Evidence D

Dandelion7 drug types · 457 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro research suggests that dandelion root inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion. Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion.

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

Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Laboratory research suggests that dandelion might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme.

Likelihood Possible Evidence D
Lithium

Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Animal research suggests that dandelion has diuretic properties. As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dandelion contains significant amounts of potassium.

Likelihood Possible Evidence D
Quinolone Antibiotics

Theoretically, dandelion might lower fluoroquinolone levels.
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73%. However, this effect has not been reported in humans.

Likelihood Possible Evidence D

Raspberry2 drug types · 135 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking red raspberry leaf with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that red raspberry leaf extract has antiplatelet activity and enhances the in vitro effects of the antiplatelet medication cangrelor. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Insulin

Red raspberry leaf might reduce glucose levels in patients being treated with insulin.
In one case report, a 38-year-old patient with gestational diabetes, whose blood glucose was being controlled with medical nutrition therapy and insulin, developed hypoglycemia after consuming two servings of raspberry leaf tea daily for 3 days beginning at 32 weeks' gestation. The patient required an insulin dose reduction. The hypoglycemia was considered to be probably related to use of red raspberry leaf tea.

Likelihood Possible Evidence D

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

Sarsaparilla2 drug types · 2 drugs

Digoxin (Lanoxin)

Theoretically, concomitant use of sarsaparilla with digoxin might increase the risk of cardiac toxicity.
Sarsaparilla is thought to have diuretic properties, which could potentially cause potassium loss. Overuse or misuse of sarsaparilla with cardiac glycoside therapy might increase the risk of cardiac toxicity due to potassium loss.

Likelihood Possible Evidence D
Lithium

Theoretically, sarsaparilla might increase the effects and adverse effects of lithium.
Sarsaparilla is thought to have diuretic properties. Due to these effects, sarsaparilla might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Vitamin B12 Herbal Lozenges Raspberry Flavor by NaturesPlus: Common Questions

Does Vitamin B12 Herbal Lozenges Raspberry Flavor by NaturesPlus interact with any medications?
Yes. Based on its ingredients, Vitamin B12 Herbal Lozenges Raspberry Flavor has a known interaction with 1,070 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vitamin B12 Herbal Lozenges Raspberry Flavor contains 5 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.
Does this lozenge actually have vitamin B12 in it?
Yes. Vitamin B12 is the main active ingredient and is rated Effective for treating B12 deficiency. It's also Likely Effective for cyanide poisoning and Possibly Effective for canker sores and nerve pain from shingles.
What are the other ingredients besides B12?
The product contains four herbal ingredients—dandelion, red raspberry leaf, beet, and sarsaparilla—plus inactive sweeteners and binders like sugar, stevia, and silica. The herbal ingredients haven't been proven effective for any condition in our available data.
Can I take this if I'm pregnant or breastfeeding?
Vitamin B12 itself is safe and actually needed during pregnancy and breastfeeding at normal amounts; follow your provider's advice. Sarsaparilla, however, should be avoided in pregnancy and breastfeeding because there isn't enough safety information. Talk with your pharmacist or doctor about the whole product before use.
What side effects might I notice?
B12 is very well tolerated orally. The herbal ingredients may cause diarrhea, heartburn, or stomach upset at higher doses. Beet may turn your stools red or black, which is harmless. Rare allergic reactions are possible, especially if you're sensitive to ragweed or related plants.
I take metformin for diabetes. Is this safe?
Metformin can lower B12 absorption over time, so B12 supplementation may be helpful—but you'll want to discuss timing and dosing with your pharmacist. The dandelion and raspberry in this product may also lower blood sugar, so that's another conversation worth having with your doctor.
I take a blood thinner. Can I use this?
Both dandelion and raspberry leaf in this product may theoretically increase bleeding risk with blood thinners. Check your exact medication with our tool and talk to your pharmacist before starting.
