Identifying Hesperidin: Common and Chemical Names
Hesperidin is a flavanone glycoside, a type of flavonoid found abundantly in citrus fruits, especially in oranges and lemons. While its most common name is hesperidin, it is also known by several scientific, chemical, and historical names. Understanding these different names can help clarify its classification and function, particularly in scientific literature and supplement formulations.
List of Alternative Names for Hesperidin
- Hesperetin-7-rutinoside: This is the precise chemical name that describes its structure as a glycoside of hesperetin with a rutinose sugar attached at the 7th position.
- Hesperidoside: A general synonym sometimes used to refer to hesperidin.
- Cirantin: An older, less common name used in some chemical contexts.
- NSC 44184: A numerical identifier associated with the compound in chemical databases.
- Citrus Bioflavonoid: A broad classification that includes hesperidin and other flavonoid compounds found in citrus fruits, such as diosmin.
- Citrus Flavone: Another general term, sometimes used interchangeably with bioflavonoid, that describes its source and class.
- Bioflavonoid Complex: Since hesperidin is often found alongside other citrus bioflavonoids in supplements and extracts, it is frequently referred to as part of a complex.
- Vitamin P: A historical and largely outdated name for bioflavonoids, including hesperidin, which was once thought to be a vitamin.
Hesperidin vs. Hesperetin: A Key Distinction
It's important to differentiate hesperidin from hesperetin, a related compound. The key difference lies in their structure: hesperidin is a glycoside, meaning it has a sugar molecule attached, while hesperetin is its aglycone, the form of the flavonoid without the sugar molecule. The body's metabolism of hesperidin often involves breaking it down into hesperetin, which is more readily absorbed.
Hesperidin vs. Hesperetin Comparison Table
| Feature | Hesperidin | Hesperetin |
|---|---|---|
| Classification | Flavanone glycoside | Flavanone aglycone |
| Structure | Includes a rutinose sugar group | Lacks the sugar group |
| Bioavailability | Poorly absorbed and limited due to low water solubility; requires metabolism by gut microbes | Readily absorbed after hesperidin is metabolized; is the active circulating form |
| Presence | Primarily found in the peel and pulp of citrus fruits | Found in smaller amounts naturally; mainly produced in the body from hesperidin |
| Solubility | Low water solubility, impacting absorption rates | More soluble and bioavailable, leading to faster absorption |
Health Benefits Associated with Hesperidin
Research into hesperidin has revealed numerous potential health benefits, many linked to its antioxidant and anti-inflammatory properties. These benefits make it a subject of interest for dietary supplements and natural medicine.
Cardiovascular Health
One of the most widely studied applications of hesperidin is its effect on blood vessel conditions and cardiovascular health. It has shown promise in improving poor circulation, potentially strengthening blood vessels and reducing inflammation. This is why it is often included in supplements targeting varicose veins and hemorrhoids.
Antioxidant and Anti-inflammatory Properties
As a potent antioxidant, hesperidin helps to combat oxidative stress by scavenging free radicals. This protective action is thought to play a role in its other health effects, including its anti-inflammatory activities. Chronic inflammation is linked to various diseases, and hesperidin's ability to modulate inflammatory markers has been noted in several studies.
Skin Health
Research has explored hesperidin's benefits for skin functions, with studies demonstrating its role in wound healing, UV protection, and improving skin permeability barrier function. Its antioxidant and anti-inflammatory mechanisms are believed to be behind these positive cutaneous effects.
Sources and Supplementation
To increase your intake of hesperidin, you can focus on consuming citrus fruits. The highest concentrations are found in the peels and white pith of oranges, lemons, and tangerines. Some studies suggest that juice processing can affect the concentration, but heat pasteurization may not always reduce the content. For concentrated doses, dietary supplements are available, often in combination with other bioflavonoids like diosmin to improve efficacy.
Bioavailability and Efficacy
One of the main challenges with hesperidin is its low bioavailability, meaning the body doesn't absorb it easily. To overcome this, some supplements use modified forms like glucosyl hesperidin, which has better water solubility. The therapeutic effects are also highly dependent on its conversion by gut microbes into the more active, absorbable form, hesperetin. For example, studies on cardiovascular benefits have shown more robust results with higher doses (over 500 mg/day) and longer treatment durations (over 6–8 weeks).
Conclusion
While hesperidin is its most common designation, the substance is also known as hesperetin-7-rutinoside, hesperidoside, and falls under the broader category of citrus bioflavonoid or historically, Vitamin P. Its identity as a flavonoid glycoside, and its relationship with its more bioavailable aglycone, hesperetin, are central to understanding its mechanism of action. The promising health benefits, particularly for cardiovascular and skin health, continue to make hesperidin a compelling natural compound for further scientific and clinical investigation. To maximize its potential, considerations regarding its bioavailability, often addressed through specific formulations, are crucial.
Potential Drug Interactions
Before taking hesperidin, be aware of potential drug interactions. Hesperidin may interact with various medications, including blood thinners, blood pressure medication, and certain chemotherapy drugs. It is important to consult a healthcare provider, especially if you are undergoing chemotherapy, as hesperidin might increase drug absorption.

Summary of Scientific Findings
- Antioxidant Action: Hesperidin effectively scavenges free radicals and reduces oxidative stress in the body.
- Anti-inflammatory Effects: It helps modulate inflammatory responses by reducing inflammatory markers.
- Cardiovascular Support: Studies show benefits for blood vessel conditions, including hemorrhoids, varicose veins, and poor circulation.
- Skin Protection: Research indicates potential for wound healing, UV protection, and improving skin barrier function.
- Metabolism and Bioavailability: The body converts hesperidin into hesperetin, a more easily absorbed metabolite, though overall bioavailability remains low.
- Supplementation Effectiveness: Higher doses over longer periods tend to yield more robust results in some studies, particularly for cardiovascular benefits.
