Hesperidin is indeed a bioflavonoid with several significant health benefits. The name hesperidin is derived from “hesperidium”.The botanical term for the type of fruit produced by citrus trees. The hesperidium is a specific type of berry with a leathery rind, characteristic of citrus fruits like oranges, lemons, and grapefruits. Hesperidin was first isolated in 1828 by French chemist M. Lebreton from the white inner layer of citrus peels.
Hesperidin content in citrus fruits, according to the review by Gattuso et al., varies depending on the type of citrus fruit and the part of the fruit being used. The highest concentrations of hesperidin are found in the peel, particularly in the flavedo (the colored outer layer) and albedo (the white, soft middle layer part of the peel). These parts of the citrus fruit contain significantly higher amounts of hesperidin compared to the juice extracted from the fruit. The peel contains more hesperidin because the flavedo and albedo are the parts of the citrus fruit that play a protective role for the fruit itself. They help to protect the fruit from environmental stresses and pathogens, and they store a large portion of the bioactive compounds, including flavonoids like hesperidin, which may contribute to the fruit’s antioxidant and anti-inflammatory properties. For those who don’t want to consume citrus peel directly, hesperidin supplements derived from citrus peel are available. These supplements typically provide a concentrated dose of the flavonoid, making it easier to get higher levels of hesperidin without having to eat large quantities of citrus. While hesperidin has garnered attention for its potential role in weight reduction and fat metabolism, it offers a wide range of other health benefits as well.
Antioxidant, anti-inflammatory, gut health, neuroprotective health, etc. One of the major drawbacks of hesperidin is its bioavailability—that is, its ability to be absorbed and utilized effectively by the body. While hesperidin is a potent bioflavonoid with numerous health benefits, it is poorly absorbed when taken orally in its natural form. This is a common issue for many flavonoids and polyphenols. However, as you pointed out, there are several strategies and technologies available to enhance its absorption and increase its effectiveness in the body. The issue can be effectively addressed using various technological advancements and natural enhancers. Methods like micro ionization, the use of absorption enhancers (such as piperine and fats), encapsulation techniques, fermentation, and combination with other bioactive compounds have all been shown to improve their bioavailability.
By utilizing these methods, the body is able to absorb and utilize hesperidin more effectively, enhancing its health benefits, including its cardioprotective, anti-inflammatory, antioxidant, and weight management effects. Therefore, while hesperidin’s absorption may initially seem like a limitation, modern approaches have provided solutions to make this valuable flavonoid more accessible to the body.
