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.

Varitonin contains five active ingredients. Vitamin C supports immune function and acts as an antioxidant.

Hesperidin Methyl Chalcone is a modified form of hesperidin, a compound from citrus. Horse Chestnut seed extract has been traditionally used for vein and circulation concerns.

Gotu Kola, an herb also called Centella asiatica, is used in traditional medicine for wound healing and vein health. Butcher's Broom is a plant extract traditionally used for circulation and vein support.

The capsule also contains inactive ingredients — hydroxypropyl methylcellulose and vegetable stearate — which are used as binders and flow agents to hold the formula together.

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Venous circulation and leg health support.
  • We looked for evidence on: Chronic venous insufficiency (CVI), Hemorrhoids, Varicose veins, Leg swelling.
  • The strongest evidence on file: Butcher's Broom is rated "Possibly Effective" for Chronic venous insufficiency (CVI) (Natural Medicines).
  • Also on file: Gotu Kola is rated "Possibly Effective" for Venous insufficiency.
  • Also on file: Horse Chestnut is rated "Possibly Effective" for Chronic venous insufficiency (CVI).

The evidence for this product's individual ingredients is mixed and often limited. Vitamin C is effective for preventing vitamin C deficiency and possibly helpful for anemia of chronic disease, exercise-related respiratory infections, atrial fibrillation, and cataracts.

Hesperidin has not shown effectiveness for obesity or high cholesterol in the studies we have; evidence for its use in nonalcoholic fatty liver disease is insufficient. Horse Chestnut is possibly effective for chronic venous insufficiency (poor circulation in the legs) but evidence is insufficient for hemorrhoids, irritable bowel syndrome, and kidney stones.

Gotu Kola is possibly effective for venous insufficiency and burns but not for radiation dermatitis or cognitive function; evidence for Alzheimer disease and generalized anxiety is insufficient. Butcher's Broom is possibly effective for chronic venous insufficiency but lacks reliable evidence for diabetic retinopathy, hemorrhoids, orthostatic low blood pressure, and lymphedema.

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 C is generally well tolerated at normal dietary and supplement doses; at very high doses (above 2 grams daily), it can cause abdominal cramps, heartburn, diarrhea, nausea, and vomiting. Kidney stones have been reported in people prone to them.

During pregnancy, normal amounts from food and prenatal vitamins are fine, but avoid high-dose supplements unless your doctor advises it. Hesperidin is generally well tolerated in food amounts and short-term use, though long-term safety data is limited; it should be avoided during pregnancy and breastfeeding due to insufficient safety information.

Horse Chestnut seed extract (properly processed to remove toxic constituents) is generally well tolerated and may cause dizziness, gastrointestinal upset, headache, or itching; however, it should be avoided during pregnancy and breastfeeding. Gotu Kola is generally well tolerated short-term but may cause nausea or gastric irritation; there are rare case reports of liver toxicity, though causation is unclear.

It should be avoided during pregnancy and breastfeeding. Butcher's Broom is generally well tolerated short-term in healthy adults and may cause diarrhea, indigestion, heartburn, nausea, or vomiting; it should be avoided during pregnancy and breastfeeding.

Hesperidin Methyl Chalcone7 drug types · 702 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, hesperidin may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Animal research suggests that hesperetin, a bioflavonoid aglycone derivative of hesperidin, may have antiplatelet activity.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking hesperidin with antihypertensive drugs might increase the risk of hypotension.
Some clinical and animal research shows that hesperidin can decrease blood pressure. However, other clinical research shows that hesperidin does not affect blood pressure.

Likelihood Possible Evidence D
Celiprolol (Celicard)

Theoretically, hesperidin may decrease the levels and clinical effects of celiprolol.
Animal research shows that concomitant use of hesperidin may reduce the plasma area under the curve of celiprolol by up to 75%. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, concomitant use with CNS depressants may cause additive sedative effects.
Animal studies show that hesperidin has sedative effects, due to opioid receptor activity and can increase sedation when used with diazepam. This effect has not been reported in humans.

Likelihood Possible Evidence D
Diltiazem (Cardizem, Others)

Theoretically, hesperidin may increase the levels and clinical effects of diltiazem.
Animal research suggests that hesperidin may enhance the bioavailability of diltiazem, increasing the plasma area under the curve of diltiazem by up to 65.3%. This effect has not been reported in humans.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, hesperidin might inhibit P-glycoprotein-mediated drug efflux and potentially increase levels of drugs that are substrates of P-glycoprotein.
In vitro research shows that hesperidin can inhibit P-glycoprotein efflux. This effect has not been reported in humans.

Likelihood Possible Evidence D
Verapamil (Calan, Others)

Theoretically, hesperidin might increase the levels and clinical effects of verapamil.
Animal research suggests that hesperidin may enhance the bioavailability of verapamil, increasing the plasma area under the curve of verapamil by 96.8%. This effect has not been reported in humans

Likelihood Possible Evidence D
Hesperidin Methyl Chalcone full monograph & interactions

Gotu Kola2 drug types · 579 drugs

Cns Depressants

Theoretically, taking gotu kola might increase the sedative effects of CNS depressants.
In vitro research suggests that gotu kola may have sedative effects via binding of GABA receptors.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking gotu kola with hepatotoxic drugs might have additive adverse effects.
There are at least four case reports of hepatotoxicity associated with the use of gotu kola. However, more information is needed to determine if gotu kola was the causative factor in these cases.

Likelihood Possible Evidence D
Gotu Kola full monograph & interactions

Vitamin C13 drug types · 207 drugs

Alkylating Agents

Theoretically, antioxidant effects of vitamin C might reduce the effectiveness of alkylating agents.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Aluminum

Vitamin C can increase the amount of aluminum absorbed from aluminum compounds.
Research in animals and humans shows that vitamin C increases aluminum absorption, theoretically by chelating aluminum and keeping it in solution where it is available for absorption. In people with normal renal function, urinary excretion of aluminum will likely increase, making aluminum retention and toxicity unlikely. Patients with renal failure who take aluminum-containing compounds such as phosphate binders should avoid vitamin C supplements in doses above the recommended dietary allowances.

Likelihood Probable Evidence B
Antitumor Antibiotics

Theoretically, the antioxidant effects of vitamin C might reduce the effectiveness of antitumor antibiotics.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as doxorubicin. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Estrogens

Vitamin C might increase blood levels of estrogens.
Increases in plasma estrogen levels of up to 55% occur under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. Increases in plasma estrogen levels may occur when patients who are deficient in vitamin C take supplements. Monitor these patients for estrogen-related side effects.

Likelihood Probable Evidence B
Fluphenazine (Prolixin)

Theoretically, vitamin C might decrease levels of fluphenazine.
In one patient there was a clinically significant decrease in fluphenazine levels when vitamin C (500 mg twice daily) was started. The mechanism is not known, and there is no further data to confirm this interaction.

Likelihood Possible Evidence D
Indinavir (Crixivan)

Vitamin C can modestly reduce indinavir levels.
One pharmacokinetic study shows that taking vitamin C 1 gram orally once daily along with indinavir 800 mg orally three times daily reduces the area under the concentration-time curve of indinavir by 14%. The mechanism of this interaction is unknown, but it is unlikely to be clinically significant in most patients. The effect of higher doses of vitamin C on indinavir levels is unknown.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Vitamin C can increase levothyroxine absorption.
Two clinical studies in adults with poorly controlled hypothyroidism show that swallowing levothyroxine with a glass of water containing vitamin C 500-1000 mg in solution reduces thyroid stimulating hormone (TSH) levels and increases thyroxine (T4) levels when compared with taking levothyroxine alone. This suggests that vitamin C increases the oral absorption of levothyroxine, possibly due to a reduction in pH.

Likelihood Probable Evidence B
Warfarin (Coumadin)

High-dose vitamin C might reduce the levels and effectiveness of warfarin.
Vitamin C in high doses may cause diarrhea and possibly reduce warfarin absorption. There are reports of two people who took up to 16 grams daily of vitamin C and had a reduction in prothrombin time. Lower doses of 5-10 grams daily can also reduce warfarin absorption. In many cases, this does not seem to be clinically significant. However, a case of warfarin resistance has been reported for a patient who took vitamin C 500 mg twice daily. Cessation of vitamin C supplementation resulted in a rapid increase in international normalized ratio (INR). Tell patients taking warfarin to avoid taking vitamin C in excessively high doses (greater than 10 grams daily). Lower doses may be safe, but the anticoagulation activity of warfarin should be monitored. Patients who are stabilized on warfarin while taking vitamin C should avoid adjusting vitamin C dosage to prevent the possibility of warfarin resistance.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

High-dose vitamin C might slightly prolong the clearance of acetaminophen.
A small pharmacokinetic study in healthy volunteers shows that taking high-dose vitamin C (3 grams) 1.5 hours after taking acetaminophen 1 gram slightly increases the apparent half-life of acetaminophen from around 2.3 hours to 3.1 hours. Ascorbic acid competitively inhibits sulfate conjugation of acetaminophen. However, to compensate, elimination of acetaminophen glucuronide and unconjugated acetaminophen increases. This effect is not likely to be clinically significant.

Likelihood Probable Evidence B
Aspirin

Acidification of the urine by vitamin C might increase aspirin levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction is not clinically significant.

Likelihood Possible Evidence B
Choline Magnesium Trisalicylate (Trilisate)

Acidification of the urine by vitamin C might increase choline magnesium trisalicylate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

Likelihood Possible Evidence B
Niacin

Vitamin C might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as vitamin C, or to the combination. It also is not known whether it will occur in other patient populations.

Likelihood Possible Evidence A
Salsalate (Disalcid)

Acidification of the urine by vitamin C might increase salsalate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams/day vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

Butcher's Broom2 drug types · 158 drugs

Alpha-Adrenergic Agonists

Theoretically, butcher's broom might increase the effects and adverse effects of alpha-adrenergic agonists.
Animal and in vitro studies show that butcher's broom has alpha-adrenergic agonist effects.

Horse Chestnut1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Horse chestnut may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Horse chestnut contains the constituent esculin which has been shown to have antithrombotic effects. Therefore, horse chestnut might have antiplatelet effects. This has not been shown in humans.

Varitonin by Douglas Laboratories: Common Questions

Does Varitonin by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Varitonin has a known interaction with 1,100 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Varitonin 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.
Can I take Varitonin if I'm pregnant?
The data we hold shows mixed safety ratings across the ingredients — vitamin C at normal doses is considered likely safe, but hesperidin, horse chestnut, gotu kola, and butcher's broom have insufficient information or should be avoided during pregnancy. Talk with your doctor or pharmacist before starting this product.
What is horse chestnut used for in this formula?
Horse Chestnut seed extract is possibly effective for chronic venous insufficiency — that's the condition where veins in the legs don't return blood efficiently, often causing swelling and discomfort. Evidence for other uses like hemorrhoids or leg symptoms is insufficient.
Does Varitonin help with circulation?
Horse Chestnut and Butcher's Broom are both possibly effective for chronic venous insufficiency, a circulation problem affecting the leg veins. Gotu Kola is also possibly effective for venous insufficiency. The other ingredients lack established evidence for circulation support in the data we hold.
What does hesperidin do?
Hesperidin Methyl Chalcone is included to support circulation and vein health, but our data shows it is possibly ineffective for obesity and high cholesterol. Evidence for its other theoretical benefits is insufficient or lacking.
Could Varitonin cause nausea?
Yes — vitamin C at high doses, gotu kola, and butcher's broom can all cause nausea or gastrointestinal upset. Horse chestnut may cause dizziness, gastrointestinal upset, or headache. If you experience nausea, stop and talk to your pharmacist.
Is there any concern about my liver with this product?
Gotu kola has rare case reports of liver toxicity associated with its use, though causation hasn't been proven and doses weren't reported in those cases. If you have liver disease or take drugs that stress the liver, discuss this product with your pharmacist first.
