HelloPharmacist Scorecard of Vital CandiPURE - Part 2 by Brenda Watson's Vital Planet

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.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 6 active ingredients.
  • “Proprietary Fluid Extract Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Vital CandiPURE - Part 2 contains 6 active ingredients in liquid form. Oregon grape root extract, fennel seed extract, pau d'Arco bark extract, lemon peel extract, oregano leaf extract, and thyme leaf extract are the working components.

The product also contains inactive ingredients—glycerin and purified water—that serve as excipients to deliver and stabilize the formula.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: maintain healthy intestinal yeast balance.
  • We looked for evidence on: Intestinal parasite infection, Urinary tract infections (UTIs), candida overgrowth, yeast infection, dysbiosis.
  • The closest evidence on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Intestinal parasite infection (Natural Medicines).
  • Also on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs).

The evidence for most of these ingredients is limited. Oregon grape is possibly effective for psoriasis, but we don't have reliable evidence for its use in eczema, acid reflux, or ulcers.

Fennel is possibly effective for period pain (dysmenorrhea) but lacks solid evidence for bronchitis, anxiety, bedwetting, or cholera. For pau d'Arco, oregano, thyme, and lemon, the data doesn't establish effectiveness for cancer, ulcers, wound healing, period pain, acne, bronchitis, asthma, headache, upper respiratory infections, hay fever, anxiety, high blood pressure, kidney stones, or the common cold.

The evidence, ingredient by ingredient Oregano Oregon Grape Fennel Pau D'arco Lemon Thyme

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Oregon grape is generally well tolerated when applied to skin, but oral use is less well studied—use caution. The berberine in it is traditionally avoided in pregnancy and may pass to infants, so don't use it if you're pregnant or breastfeeding.

Fennel is safe as a food but concentrated supplements and essential oils warrant more caution; avoid medicinal amounts in pregnancy. Food amounts are likely fine while breastfeeding, but medicinal doses aren't well studied.

Fennel may cause gastrointestinal upset, sun sensitivity, or allergic reactions—rarely, seizures. One case describes an allergic reaction (sneezing, coughing, wheezing, difficulty breathing) from fennel toothpaste.

Pau d'Arco should be avoided in pregnancy and breastfeeding. At high doses (above 1.5 grams daily of its lapachol component), it may cause anemia, bleeding risk, and severe nausea, vomiting, or diarrhea.

Lemon as food is safe in normal amounts; concentrated supplements or essential oils need doctor approval. Fresh lemon juice at 60 mL twice daily caused gastrointestinal upset in 37% of trial participants versus 8% on placebo.

Oregano is safe as food; medicinal amounts should be avoided in pregnancy unless approved by your doctor. Oral oregano is well tolerated in food amounts; gastrointestinal upset is the most common side effect at higher doses.

Rare systemic allergic reactions including anaphylaxis have been reported. Thyme is generally safe as food and in tea, but the concentrated essential oil can be toxic if swallowed.

Food amounts are likely fine in pregnancy and breastfeeding, but medicinal or essential-oil amounts should be avoided.

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?
  • 6 of the 6 matched ingredients can interact with medications — Fennel, Oregon Grape, Lemon, Oregano, Pau D'arco, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,327 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 these medication types with your pharmacist: blood thinners (anticoagulants or antiplatelet drugs) at Moderate risk; blood pressure drugs, CNS depressants, and diabetes medications at Moderate risk; and any drug your liver processes via CYP2D6, CYP2C9, or CYP3A4 enzymes at Moderate risk. Birth control pills, hormone replacement therapy, the immunosuppressant cyclosporine, the antibiotic ciprofloxacin, the breast-cancer drug tamoxifen, nerve-signaling medications, and the antifungal itraconazole also carry documented interactions.

If you're on any of these, do not start this supplement without talking to your pharmacist first.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, Oregon grape might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research suggests that berberine, a constituent of Oregon grape, can lower blood glucose levels.

Likelihood Possible Evidence A
Antihypertensive Drugs

Theoretically, Oregon grape might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research suggests that berberine, a constituent of Oregon grape, can have hypotensive effects. Also, an analysis of clinical evidence suggests that taking berberine in combination with amlodipine (Norvasc) can lower systolic and diastolic blood pressure when compared with taking amlodipine alone.

Animal research suggests that berberine, a constituent of Oregon grape, can have sedative effects.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, Oregon grape might increase the effects and adverse effects of cyclosporine.
Berberine, a constituent of Oregon grape, can reduce metabolism of cyclosporine and increase serum levels. It might inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, Oregon grape might increase serum levels of drugs metabolized by CYP2C9.
Preliminary clinical evidence suggests that berberine, a constituent of Oregon grape, can inhibit cytochrome P450 2C9 (CYP2C9).

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, Oregon grape might increase serum levels of drugs metabolized by CYP2D6.

In vitro research suggests that Oregon grape extracts inhibit P-gp efflux.

Likelihood Possible Evidence D

Fennel seed extract6 drug types · 742 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, fennel might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.

Animal research suggests that fennel oil has antithrombotic and antiplatelet effects.

Likelihood Possible Evidence D
Ciprofloxacin (Cipro)

Theoretically, fennel might decrease the levels and clinical effects of ciprofloxacin.

Animal research shows that fennel reduces ciprofloxacin bioavailability by nearly 50%, possibly due to the metal cations such as calcium, iron, and magnesium contained in fennel. This study also found that fennel increased tissue distribution and slowed elimination of ciprofloxacin.

Likelihood Probable Evidence D
Contraceptive Drugs

Theoretically, taking large amounts of fennel might decrease the effects of contraceptive drugs due to competition for estrogen receptors.

Some constituents of fennel have estrogenic activity.

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

Theoretically, fennel might increase levels of drugs metabolized by CYP3A4.

In vitro research suggests that fennel inhibits CYP3A4 enzyme activity. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, taking large amounts of fennel might interfere with hormone replacement therapy due to competition for estrogen receptors.

Some constituents of fennel have estrogenic activity.

Likelihood Possible Evidence D

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, thyme leaf extract might have additive effects with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that thyme leaf extract has antiplatelet effects. However, this effect has not been observed in humans.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, concurrent use of cholinergic drugs and thyme essential oil might cause additive cholinergic effects.
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE). However, this effect has not been observed in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, thyme might competitively inhibit the effects of estrogen replacement therapy.
In vitro research shows that thyme has estrogen receptor-binding activity and phytoestrogen content. However, this effect has not been observed in humans.

Likelihood Possible Evidence D

Oregano Leaf Extract2 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, oregano might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that aristolochic acid isolated from oregano leaves has antithrombin activity. It has also been reported that oregano oil inhibits arachidonic acid-induced, and ADP-induced, platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, oregano might increase the risk for hypoglycemia when taken with antidiabetes drugs.
In vitro and animal research shows that oregano extracts might lower blood glucose levels.

Likelihood Possible Evidence D

Pau d'Arco Bark Extract1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, pau d'arco might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that pau d'arco reduces platelet aggregation and may interfere with vitamin K. One clinical study shows that taking the lapachol constituent of pau d'arco in doses above 1.5 grams daily increases the risk of bleeding. The effects of whole pau d'arco or pau d'arco extract in humans are unclear.

Likelihood Possible Evidence D

Lemon Peel Extract1 drug type · 1 drug

Itraconazole (Sporanox)

Theoretically, taking itraconazole capsules or tablets with a beverage containing lemon might increase the levels and clinical effects of itraconazole.
In one case report, dissolving itraconazole tablets in a small amount of specific beverages containing lemon prior to administration increased the level of itraconazole in a lung transplant patient. In this case, the increased bioavailability was desirable and was likely due to improved tablet dissolution in the acidic beverage.

Vital CandiPURE - Part 2 by Brenda Watson's Vital Planet: Common Questions

Does Vital CandiPURE - Part 2 by Brenda Watson's Vital Planet interact with any medications?
Yes. Based on its ingredients, Vital CandiPURE - Part 2 has a known interaction with 1,326 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vital CandiPURE - Part 2 contains 6 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 use this if I'm pregnant or breastfeeding?
No, you should avoid this product during pregnancy and breastfeeding. Oregon grape and pau d'Arco are traditionally avoided in pregnancy due to possible harm, and berberine may pass to infants. Fennel should be avoided in medicinal amounts during pregnancy due to hormone-like effects and limited safety data. Oregano medicinal amounts should also be avoided in pregnancy. Talk with your doctor about what's safe for you.
Does this product actually work?
The evidence is limited. Oregon grape is possibly effective for psoriasis, and fennel is possibly effective for period pain. For the other conditions this product might be marketed for—bronchitis, asthma, anxiety, common cold, and others—we don't have reliable evidence that these ingredients work.
What are the side effects?
Most common are gastrointestinal issues (nausea, vomiting, diarrhea, heartburn, upset stomach) and allergic reactions in sensitive people. Oregon grape applied to skin may cause itching, burning, or irritation. Thyme and oregano can cause contact dermatitis if applied topically. Rare but serious: fennel and oregano have been linked to seizures and anaphylaxis in very sensitive individuals.
Can I take this with blood thinners like warfarin or aspirin?
No, not without talking to your doctor first. Oregon grape, fennel, pau d'Arco, oregano, and thyme all carry Moderate interaction risks with blood thinners and may increase your bleeding risk. This is a serious interaction that needs professional review.
What is the proprietary blend, and what does it do?
The proprietary fluid extract blend in this product is made up of the six individual extract ingredients listed on the label (Oregon grape, fennel, pau d'Arco, lemon peel, oregano, and thyme). We can't tell you the exact amount of each one because the brand keeps that proportion confidential.
Will this raise or lower my blood sugar?
Oregon grape and oregano both contain compounds that research suggests can lower blood glucose levels. If you take diabetes medications, this product could increase your risk of low blood sugar (hypoglycemia). Check with your pharmacist before starting.
