Hesperidin

Hesperidin citrus flavanone glycoside

Hesperidin is a citrus flavonoid studied in adults for cardiometabolic markers, not for direct cognitive benefits. Compare the form, declared amount, and source-backed cautions before choosing a product.

01

What is it?

What the human evidence covers

1

Hesperidin is a citrus flavonoid. Adult trials and pooled analyses primarily examine cardiometabolic markers; they do not establish a direct benefit for memory, focus, or other cognitive outcomes.

02

Names, aliases and forms

Common NameHesperidin
Active ConstituentCitrus flavanone glycoside
03

Mechanisms of action

Mechanism context

1

Hesperidin is metabolized to related compounds such as hesperetin. Laboratory pathway observations do not establish effects on cognition or clinical outcomes in people.

04

Potential effects and evidence map

Human trials and meta-analyses examine cardiometabolic markers, with inconsistent results across outcomes and populations. No reliable human evidence establishes a direct cognitive benefit.

Research exposure, not a recommendation1500-1000 mg/day

Adult trial protocols vary. Dose-response subgroup analyses often evaluated 500-1000 mg/day over several weeks; this describes research exposure, not a recommended intake or an interchangeable product dose.

06

Safety, side effects and risk profile

Form-specific safety limits4
EFSA's 2024 assessment reported no clinically relevant hematology or chemistry changes in human studies of glucosyl hesperidin up to 3 g/day for 12 weeks. That finding is specific to glucosyl hesperidin and its assessed uses, not every concentrated hesperidin product.
Interaction risk1
Confidence: Medium

Clinical interaction data for concentrated products are limited; review prescription medicines with a pharmacist before use.

Note Do not extrapolate laboratory flavonoid findings to a predictable clinical interaction.

2/5
D
Pregnancy / lactation caution4
Confidence: High

No adequate pregnancy or lactation conclusion was identified for concentrated hesperidin products.

Note Food exposure does not establish the safety of a concentrated supplement in these populations.

2/5
E
Evidence uncertainty2
Confidence: High

Outcome estimates differ among pooled analyses and study populations; avoid using this profile as a health-outcome promise.

Note The page reports uncertainty rather than a health outcome claim.

Interactions and cautions

Medication and population caution4

A reliable clinical interaction map for concentrated hesperidin products was not identified. If you use prescription medicine, are pregnant, or are breastfeeding, discuss a concentrated product with a pharmacist or clinician before use.

09

Practical buying and quality notes

  • Compare the declared hesperidin amount per serving, chemical form, citrus source, and independent identity or purity testing. Hesperidin, glucosyl hesperidin, and blended citrus extracts should not be assumed interchangeable.4
