HelloPharmacist Scorecard of Muscadine Grape Seed & Skins by Mighty Muscadine
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
Mighty Muscadine is a single-ingredient supplement: muscadine grape seed and skins. The only other item in the capsule is hypromellose, an inactive ingredient used to form the capsule shell.
Does it work?
Couldn't assess
The evidence we hold shows muscadine grape may help with chronic venous insufficiency (CVI)—a condition where poor circulation causes leg swelling and discomfort—though the data is rated possibly effective, meaning it shows promise but isn't definitive. For other uses like chemotherapy-related nausea, hay fever, and weight management, the evidence available to us is rated possibly ineffective.
How safe is it?
Well-documented data
Grapes as a whole food are safe for most people, and grape seed extract is generally well tolerated in studies. The most common side effects are mild—abdominal pain, diarrhea, dry mouth, indigestion, headache, joint pain, and nausea.
Anaphylaxis (a severe allergic reaction) to grape skin is rare but has been reported. Because safety data for concentrated grape supplements in pregnancy is limited, the safety notes advise against them during pregnancy; grapes as food are fine.
For breastfeeding, there isn't enough information on concentrated supplements, so talk with your pharmacist or doctor for personalized guidance.
Meds to double-check
Moderate interaction found
Before taking Mighty Muscadine, check whether you're on blood thinners or antiplatelet drugs like warfarin or clopidogrel (Moderate severity). Also double-check CYP2D6 substrates, CYP3A4 substrates, and CYP1A2 substrates (all Moderate), as well as cyclosporine and midazolam.
Use the medication checker below to be sure.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you're dealing with chronic venous insufficiency and aren't on blood thinners, this may be worth considering. If you take any prescription medication—especially blood thinners, cyclosporine, or sedatives—check it against our tool first.

Muscadine Grape Seed & Skins by Mighty Muscadine Drug Interactions
HelloPharmacist Interaction Report
Mighty Muscadine contains muscadine grape, which has documented interactions with several medication types.
The most serious concern involves blood thinners and antiplatelet drugs (those that prevent clots): grape extracts may have blood-thinning effects themselves and could increase your bleeding risk if combined with medications like warfarin or aspirin.
Read the full breakdown — every affected drug type, severity by severity
Grape also affects how your liver processes certain medications. It may reduce levels of some CYP1A2 substrates (like phenacetin) by increasing how fast your body clears them.
Conversely, it may increase levels of CYP2D6 and CYP2E1 substrates by slowing their breakdown. The picture with CYP3A4 substrates is mixed—lab evidence suggests inhibition, but animal studies suggest induction, and human data is lacking.
Additionally, grape juice specifically can reduce cyclosporine absorption by up to 30%, and long-term grape seed extract may decrease midazolam effectiveness.
Altogether, these interactions span 900 individual medications. To see if any of your prescriptions are affected, check them with the search tool on this page.

For each ingredient in Muscadine Grape Seed & Skins with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Muscadine Grape
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.
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.
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.
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.
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.
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.
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.
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).
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.
