HelloPharmacist Scorecard of Citrus Bergamot Extract 1000 mg by Double Wood Supplements

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

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 0 of its 7 active ingredients.
  • “Citrus Bergamot extract” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.
  • “Bergamonte Full Spectrum Citrus Bergamia Risso Fruit Extract Complex” is a proprietary blend — the label doesn't break down how much of each component you get.

This product contains 7 ingredients total. The active ones are vitamin C, pectin, naringin, citrus bergamot extract, and several compounds found in bergamot citrus (neoeriocitrin, neohesperidin, melitidin, and bruteridine).

The inactive ingredients—hypromellose, microcrystalline cellulose, and rice flour—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
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: supports healthy cholesterol levels.
  • We looked for evidence on: Hypercholesterolemia, Hyperlipidemia, Atherosclerosis, Cardiovascular disease (CVD), Metabolic syndrome, dyslipidemia — and 1 related terms.
  • The strongest evidence on file: Pectin is rated "Possibly Effective" for Hypercholesterolemia (Natural Medicines).
  • Also on file: Vitamin C is rated "Possibly Effective" for Hypercholesterolemia.
  • Also on file: Vitamin C is rated "Possibly Ineffective" for Atherosclerosis, Cardiovascular disease (CVD).

Vitamin C is effective for preventing and treating vitamin C deficiency, and possibly effective for anemia of chronic disease, atrial fibrillation, cataracts, and protecting against exercise-related respiratory infections. Pectin is possibly effective for high cholesterol, but the evidence for its use in prediabetes and radiation exposure is insufficient to rate.

We hold no effectiveness data for the citrus bergamot compounds themselves (naringin, neoeriocitrin, neohesperidin, melitidin, bruteridine, or the extract as a whole).

The evidence, ingredient by ingredient Bergamot

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • 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 doses from food and supplements, but very high doses—above 2 grams daily—can cause abdominal cramps, heartburn, diarrhea, nausea, and kidney stones in those prone to them. At high doses, it has rarely caused kidney damage.

Pectin from food and typical supplement amounts is also well tolerated; most people experience only mild gas, loose stools, or cramps. Allergic reactions to pectin are rare but possible.

Pregnancy: normal dietary amounts of vitamin C are fine, but avoid high-dose supplements unless your doctor advises it. Pectin supplement safety in pregnancy hasn't been well studied—check with your doctor.

Breastfeeding: dietary amounts of both are considered safe; supplement safety while breastfeeding isn't well established.

Side effects, ingredient by ingredient Bergamot

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?
  • 2 of the 2 matched ingredients can interact with medications — Pectin, Vitamin C.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; cancer treatments; heart-rhythm medications.
  • For scale: 226 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.

Check with your doctor or pharmacist before using this product if you take blood thinners like warfarin, estrogens or oral contraceptives, heart medications like digoxin or lovastatin, thyroid replacement (levothyroxine), tetracycline or other antibiotics, HIV medications like indinavir, or chemotherapy drugs. Vitamin C and pectin in this product can affect how these medications are absorbed or work in your body.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is worth considering if you're looking for vitamin C and pectin for general wellness, especially if you're low in vitamin C. However, if you take birth control, hormone therapy, blood thinners, heart medications, thyroid replacement, or any prescription drug, talk with your own doctor or pharmacist before starting it—vitamin C and pectin can interfere with how some medications work.

High doses of vitamin C are best avoided unless specifically directed by your healthcare provider.

Citrus Bergamot Extract 1000 mg by Double Wood Supplements: Common Questions

Does Citrus Bergamot Extract 1000 mg by Double Wood Supplements interact with any medications?
Yes. Based on its ingredients, Citrus Bergamot Extract 1000 mg has a known interaction with 597 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Citrus Bergamot Extract 1000 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Is this product safe to take with my birth control?
Vitamin C in this product can increase blood levels of estrogens in birth control pills by up to 55% under some circumstances. This doesn't automatically mean it's unsafe, but you should talk with your doctor or pharmacist about whether to take this product alongside your birth control to make sure the interaction won't affect your protection or side effects.
What is citrus bergamot extract used for?
We hold effectiveness data only for vitamin C and pectin in this product. The citrus bergamot compounds themselves (naringin, neoeriocitrin, and others) have no documented effectiveness information in our data, so we can't tell you what they're meant to do.
Will this product cause side effects?
Vitamin C is well tolerated, but doses above 2 grams daily can cause heartburn, diarrhea, cramps, or nausea. Pectin may cause mild gas, loose stools, or cramping. Allergic reactions to pectin are rare but possible. If you're prone to kidney stones or have kidney disease, high-dose vitamin C poses additional risk.
Is it safe to take while pregnant?
Normal dietary amounts of vitamin C are fine in pregnancy. The pectin in this product hasn't been well studied in pregnancy, and vitamin C as a high-dose supplement is not recommended unless your doctor directs it. Talk with your doctor or pharmacist before starting this product if you're pregnant.
Can I take this with my thyroid medication?
Vitamin C can increase how much levothyroxine your body absorbs, which may change your thyroid levels. If you take thyroid replacement, check with your own doctor or pharmacist before adding this product—you may need a dose adjustment or different timing.
How much vitamin C is in each capsule?
The product facts don't break down the dose of each ingredient inside the capsule—only that it's a 1000 mg formula overall. You may want to contact the manufacturer or check the label for the exact vitamin C amount per dose.
