Hesperidin is a powerful antioxidant derived from immature citrus fruit.

Hesperidin is a flavonoid, a type of plant pigment with antioxidant properties.¹ ² It is primarily derived from the skin of immature citrus fruit and can also be found in lower concentration in some vegetables and aromatic herbs.³ 

Benefits of Hesperidin

The health benefits of hesperidin were recognized early after it’s discovery; it was initially erroneously identified as a vitamin, “vitamin P”.⁴  

Over the past decade, numerous scientific studies have validated the health benefits of hesperidin.⁵ Research has demonstrated that hesperidin may be effective in supporting immune function.

Hesperidin supports immune function

Hesperidin has been demonstrated to have antimicrobial activity through its antioxidant and radical scavenging properties.⁶

Recent results demonstrate that hesperidin may attenuate influenza A virus (H1N1) induced lung injury⁷ and may also have antiviral properties against SARS-CoV-2.⁸

What to look for in a hesperidin supplement?

Hesperidin is sometimes confused with hesperidin methylchalcone or hesperetin which are in fact structural analogues of hesperidin.

Look at the product label to make sure the active ingredient is hesperidin. You should also take note of the amount of hesperidin: the recommended dose is 1000mg per day taken on an empty stomach.
