HelloPharmacist Scorecard of VesselMax by Ortho Molecular Products

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
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.

VesselMax contains four active ingredients. Horse chestnut seed extract is included for its effects on chronic venous insufficiency (a condition where blood pools in the legs and causes discomfort and swelling).

Diosmin (marketed here as usminPlus) is a bioflavonoid meant to support venous and lymphatic function. Gotu kola aerial parts extract is added for its potential effects on venous insufficiency and wound healing.

Troxerutin, the fourth active, rounds out the formulation. The product also contains inactive ingredients—hypromellose, magnesium stearate, silicon dioxide, and stearic acid—which are fillers and capsule materials that have no therapeutic role.

Does it work?

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

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

Moderate

Some 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: Burns — rated "Possibly Effective" (Gotu Kola) (Natural Medicines).
  • On file: Venous insufficiency — rated "Possibly Effective" (Gotu Kola) (Natural Medicines).
  • On file: Chronic venous insufficiency (CVI) — rated "Possibly Effective" (Diosmin) (Natural Medicines).
  • On file: Hemorrhoids — rated "Possibly Effective" (Diosmin) (Natural Medicines).
  • On file: Venous leg ulcers — rated "Possibly Effective" (Diosmin) (Natural Medicines).

Horse chestnut seed extract is rated possibly effective for chronic venous insufficiency, but evidence is not conclusive for hemorrhoids, irritable bowel syndrome, or kidney stones. Diosmin is also possibly effective for chronic venous insufficiency, venous leg ulcers, and hemorrhoids; the evidence for back pain and diabetic neuropathy is insufficient.

Gotu kola is possibly effective for venous insufficiency and burns, but possibly ineffective for radiation dermatitis and cognitive function. We hold no effectiveness data for troxerutin in the facts provided.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Horse chestnut seed extract is generally well tolerated when properly processed to remove toxic compounds, but the raw plant parts are toxic. The most common side effects from the extract are dizziness, gastrointestinal upset, headache, and itching.

Rarely, calf spasms or serious cardiovascular events have been reported. Diosmin is generally well tolerated short-term; common side effects include abdominal pain, diarrhea, dizziness, nausea, and skin irritation, with rare serious effects like cardiac arrhythmias or hemolytic anemia.

Gotu kola is well tolerated short-term, with gastric irritation and nausea being most common, but there are rare reports of liver toxicity—though contaminants in those products could not be ruled out. Horse chestnut is not recommended during pregnancy or breastfeeding due to insufficient safety data.

Diosmin is rated likely safe or possibly safe for pregnancy and lactation. Gotu kola is possibly safe in pregnancy but should be avoided during breastfeeding because safety is unknown.

Talk with your doctor or pharmacist about whether any of these ingredients are right for you if you are pregnant, breastfeeding, or planning to become pregnant.

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?
  • 3 of the 3 matched ingredients can interact with medications — Gotu Kola, Diosmin, Horse Chestnut.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 1,159 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 VesselMax, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or aspirin)—horse chestnut and diosmin both carry a moderate bleeding risk. Also flag any seizure medications (like carbamazepine), muscle relaxants (like chlorzoxazone), certain pain relievers (like diclofenac), sedatives or CNS depressants, or drugs that work through P-glycoprotein—diosmin may raise their blood levels.

If you have liver problems or take hepatotoxic drugs, gotu kola warrants discussion too.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

VesselMax is designed for people dealing with chronic venous insufficiency or related circulatory issues, and the combination of horse chestnut and diosmin has some evidence behind it for that use. If you take blood thinners, antiplatelet drugs, sedatives, seizure medications, muscle relaxants, or anti-inflammatory drugs, or if you have liver concerns, check your exact medications with your doctor or pharmacist before starting this product.

usminPlus9 drug types · 885 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, diosmin may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
A case of spontaneous intraventricular hemorrhage has been reported for a 77-year-old female after 6 weeks of warfarin therapy, despite an international normalized ratio (INR) of only 1.8. The patient had also been taking aspirin and diosmin for several years. Experts speculate that chronic intake of diosmin predisposed the patient to spontaneous intraventricular hemorrhage by inducing chronic microcirculatory hypertension and inhibiting platelet aggregation. The presence of aspirin was also thought to play a role in this event.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, diosmin might reduce the effects of carbamazepine and increase the risk for convulsions.
A pharmacokinetic study in humans shows that taking diosmin (Venex) 500 mg daily for 10 days prior to oral administration of carbamazepine 200 mg increases blood levels of carbamazepine by approximately 58% and decreases carbamazepine clearance by 42%. It also decreases the formation of carbamazepine's active metabolite. It is speculated that diosmin reduces the metabolism of carbamazepine by inhibiting cytochrome P450 3A4 (CYP3A4).

Likelihood Probable Evidence B
Chlorzoxazone (Parafon Forte, Paraflex)

Theoretically, diosmin might increase the levels and clinical effects of chlorzoxazone.
A pharmacokinetic study in humans shows that taking diosmin (Venex 500) 500 mg daily for 9 days prior to oral administration of chlorzoxazone 250 mg increases blood levels of chlorzoxazone by 53% and decreases chlorzoxazone clearance by 40%. It is speculated that diosmin reduces the metabolism of chlorzoxazone by inhibiting cytochrome P450 2E1 (CYP2E1).

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

Theoretically, diosmin might inhibit the metabolism of CYP2C9 substrates.
Diclofenac is metabolized by CYP2C9 enzymes. Clinical and laboratory research shows that diosmin inhibits the metabolism of diclofenac. A pharmacokinetic study in humans shows that taking diosmin (Venex 500) 500 mg daily for 9 days prior to oral administration of diclofenac 100 mg increases blood levels of diclofenac and decreases diclofenac clearance.

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

Theoretically, diosmin might inhibit the metabolism of CYP2E1 substrates.
Chlorzoxazone is metabolized by CYP2E1 enzymes. A pharmacokinetic study in humans shows that taking diosmin (Venex 500) 500 mg daily for 9 days prior to oral administration of chlorzoxazone (Paraflex 250) 250 mg increases blood levels of chlorzoxazone by 34% and decreases chlorzoxazone clearance by 40%. It is speculated that diosmin reduces the metabolism of chlorzoxazone by inhibiting CYP2E1.

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

Theoretically, diosmin might inhibit the metabolism of CYP3A4 substrates.
Laboratory research is conflicting with respect to the effects of diosmin on CYP3A4. Some research suggests that diosmin does not affect CYP3A4 activity. However, other research suggests that diosmin alters the metabolism of carbamazepine, a CYP3A4 substrate. Laboratory and animal research show that oral administration of diosmin for 7 days prior to oral administration of carbamazepine increases plasma concentrations of carbamazepine, decreases the clearance of carbamazepine, and decreases the formation of carbamazepine's active metabolite. Additionally, pharmacokinetic research in healthy male subjects shows that taking diosmin (Venex) 500 mg daily for 10 days prior to oral administration of carbamazepine 200 mg increases blood levels of carbamazepine by approximately 58% and decreases carbamazepine clearance by 42%. It is speculated that diosmin reduces the metabolism of carbamazepine by inhibiting CYP3A4. Diosmetin, a metabolite of diosmin, may also inhibit CYP3A4.

Likelihood Possible Evidence B
Diclofenac (Voltaren, Others)

Theoretically, diosmin might increase the levels and clinical effects of diclofenac.
Clinical and laboratory research shows that diosmin inhibits the metabolism of diclofenac. A pharmacokinetic study in humans shows that taking diosmin (Venex 500) 500 mg daily for 9 days prior to oral administration of diclofenac 100 mg increases blood levels of diclofenac and decreases diclofenac clearance. It is speculated that diosmin reduces the metabolism of diclofenac by inhibiting cytochrome P450 2C9 (CYP2C9).

Likelihood Probable Evidence B
Fexofenadine (Allegra)

Theoretically, diosmin might increase the levels and clinical effects of fexofenadine.
A pharmacokinetic study in humans shows that taking diosmin (Venex) 500 mg daily for 10 days prior to oral administration of fexofenadine 120 mg increases blood levels of fexofenadine by approximately 49% and decreases the apparent oral clearance of fexofenadine by 41%. The time taken to reach maximum plasma concentration, the half-life, and the apparent renal clearance of fexofenadine are not affected. For this reason, it is speculated that diosmin alters the pharmacokinetics of fexofenadine via inhibition of P-glycoprotein in the intestine, but not in the kidney or liver.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Theoretically, diosmin might increase levels of drugs that are substrates of P-glycoprotein (P-gp).
Preliminary laboratory research suggests that diosmin inhibits P-gp. Additionally, pharmacokinetic research in healthy male subjects shows that taking diosmin (Venex) 500 mg daily for 10 days prior to oral administration of fexofenadine 120 mg increases blood levels of fexofenadine, a P-gp substrate, by approximately 49% and decreases the apparent oral clearance of fexofenadine by 41%. The time taken to reach maximum plasma concentration, the half-life, and the apparent renal clearance of fexofenadine are not affected. For this reason, it is speculated that diosmin inhibits P-gp in the intestine, but not in the kidney or liver.

Gotu Kola Aerial Parts Extract2 drug types · 581 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.

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.

VesselMax by Ortho Molecular Products: Common Questions

Does VesselMax by Ortho Molecular Products interact with any medications?
Yes. Based on its ingredients, VesselMax has a known interaction with 1,158 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
VesselMax 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 VesselMax if I'm on warfarin or another blood thinner?
Not without checking with your doctor first. Both horse chestnut and diosmin in this product carry a moderate risk of increasing bleeding when combined with blood thinners or antiplatelet drugs like aspirin. There's even a case report of serious bleeding in someone taking warfarin, aspirin, and diosmin together.
What are the most common side effects I might notice?
The main ones are gastrointestinal—diarrhea, nausea, abdominal pain, and gastric irritation. Dizziness and skin irritation are also possible. Most side effects are mild and short-term, though if you develop liver symptoms or chest pain, stop and seek medical attention.
Is it safe to take while I'm pregnant or breastfeeding?
Horse chestnut should be avoided in both pregnancy and breastfeeding due to insufficient safety data. Diosmin is likely or possibly safe during pregnancy and lactation. Gotu kola is possibly safe in pregnancy but not recommended while breastfeeding. Talk with your doctor or pharmacist about your specific situation.
Does VesselMax actually work for leg swelling or varicose veins?
The evidence shows that horse chestnut and diosmin are possibly effective for chronic venous insufficiency, the condition behind that kind of swelling. That means some evidence supports it, but results aren't guaranteed for everyone and the research isn't conclusive.
Can VesselMax interact with seizure medications or muscle relaxants?
Yes, diosmin in this product may slow how your body breaks down carbamazepine (a seizure medication) and chlorzoxazone (a muscle relaxant), potentially raising their blood levels. Check with your pharmacist or doctor before combining them.
Is there any concern about liver health with this product?
Gotu kola in VesselMax carries a rare risk of liver toxicity, though reported cases were not fully confirmed and higher doses were sometimes involved. If you have existing liver problems or take other drugs that stress the liver, mention this product to your doctor.
