Best Citrus Bergamot 2026: Ranked by Standardization & Cost per Day
Informational summary — not medical advice. This page ranks product transparency and value; on what the research shows, see the hub and the evidence breakdown. If you take a statin or other prescription medication, talk to your clinician before adding bergamot — it shares grapefruit's CYP3A4 drug-interaction chemistry. This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
If you're going to try bergamot despite the thin evidence, buy a standardized-polyphenol product — and talk to your doctor first if you take a statin. Of the 6 citrus bergamot products tracked here, only 1 discloses a polyphenol percentage: Citrus Bergamot 150:1 (70%), at $0.38/day. It is not the cheapest option, and that's the point — the trials tested a specific standardized extract, and an unstandardized label can't be verified to match it at any price. Two other products are flagged separately for dose: one sits near a dose that failed in a null trial, one exceeds the highest tested dose in this pack.
As an Amazon Associate we earn from qualifying purchases. Ranked by disclosed polyphenol standardization first, cost per mg second, never commissions.
The one-line takeaway Citrus Bergamot 150:1's 70% polyphenol disclosure is the only label in this set you can actually compare to the trial material — that makes it the top pick even at a higher cost per day than the cheapest options. Nutricost is the best value among the unstandardized products still inside the trial-adjacent dose range. Cost per mg alone is not the whole comparison — the two lowest-cost products here are also the two products listed last because of their doses.
Every product compared: standardization, dose & cost
Sorted standardized product first, then unstandardized products inside the typical trial-adjacent dose range by cost per mg, then the two products with dose-range notes last regardless of price. Full data is a public CC BY JSON file.
| Product | mg/serving | Polyphenols disclosed | $/day | $/mg | Dose vs trials |
|---|---|---|---|---|---|
| Citrus Bergamot 150:1 Extract, 70% Polyphenols, Italian Sourced (1200mg) | 1200 mg | 70% | $0.38 | $0.0003 | Standardized pick |
| Nutricost Citrus Bergamot 1200mg (2x600mg Capsules) | 1200 mg | Not disclosed | $0.25 | $0.0002 | In trial-adjacent range |
| Secret Element Citrus Bergamot Extract 1000mg | 1000 mg | Not disclosed | $0.20 | $0.0002 | In trial-adjacent range |
| Double Wood Citrus Bergamot 1000mg (Bergamonte Standardization, NSF Certified) | 1000 mg | Not disclosed | $0.35 | $0.0003 | In trial-adjacent range |
| tnvitamins Citrus Bergamot 2000mg | 2000 mg | Not disclosed | $0.09 | $0.0000 | Above highest studied dose ⚠ |
| NusaPure Citrus Bergamot 600mg | 600 mg | Not disclosed | $0.14 | $0.0002 | Near a studied dose with no change ⚠ |
Prices are Amazon buy-box figures, verified July 19, 2026; they move. Cost per day = price ÷ servings per container at the label serving. Cost per mg = price ÷ (servings × total mg per serving) — not polyphenol-adjusted, since 5 of 6 products don't disclose that figure.
Two things to read before you compare on price alone
Citrus Bergamot 150:1's 70% polyphenol disclosure is the headline recommendation despite not being the cheapest. The trials we reviewed tested a specific standardized bergamot polyphenolic fraction (BPF) — not generic "bergamot extract." A label that states only a total milligram figure, with no polyphenol percentage, cannot be verified to deliver anything close to what the trials tested. Standardization transparency is a real quality signal here, the same way a disclosed silymarin % matters for milk thistle or a disclosed AKBA % matters for boswellia — and only one product in this set provides it.
NusaPure's 600mg/day has one of the lowest costs per mg here. Its dose is close to the 500mg/day dose studied in Bruno 2017, a trial that reported no change in its metabolic measures. This label does not disclose standardization, so we list it after the products with disclosed or in-range doses.
tnvitamins's 2000mg/day has one of the lowest costs per mg here. The highest dose in any trial we reviewed is 1300mg/day (Capomolla 2019's high-dose arm). This label's dose is more than 50% above that, and it does not disclose standardization, so we list it after the products with disclosed or in-range doses.
Verification check · Citrus Bergamot
What we could and could not verify about Citrus Bergamot
Not one of the 6 Citrus Bergamot products we track appears in the NSF, USP or Informed Sport registries. 1 of the 6 still advertise testing of some kind, wording those registries cannot confirm for Citrus Bergamot. A “cGMP” line audits the factory, not the Citrus Bergamot bottle you would actually receive.
Method: our Citrus Bergamot roster matched against the full public registries of third-party-certified supplements in the US, NSF/ANSI 173, USP Verified and Informed Sport, 5,317 listings, retrieved 2026-08-25. Absence means nobody independent has checked that Citrus Bergamot product, not that it failed. Full method and limitations.
Frequently asked questions
What is the best citrus bergamot supplement?
The one that discloses polyphenol standardization — only 1 of 6 products here does. That product is the top pick even though it isn't the cheapest, because the trials tested a specific standardized material.
Why does standardization matter so much for bergamot?
The trials tested a specific standardized fraction (BPF), not generic extract. Without a disclosed polyphenol %, there's no way to know how a product compares to what was actually studied.
Why are two low-cost products listed last?
Both have a low cost per mg here, but one sits near a dose studied in a trial that reported no change and the other is above the highest dose studied. Low cost alone is not the whole comparison.
