The unique product is the first 100% soluble form of hesperidin — a flavonoid that occurs naturally in citrus fruits.
Its vasodilatory and pump effects make it ideal for pre-work-out applications.
In CitraPeak, hesperidin is bonded to tapioca starch, making it 100,000 times more soluble and 347 times more bioavailable than standard hesperidin, allowing rapid activation.
The benefits of CitraPeak are supported by a range of published clinical studies. They include the following.
- Increase in physical output: Research shows that CitraPeak helps increase, energy and physical output.
- Rapid release: More than 100,000 times more soluble and 347 times more bioavailable than standard hesperidin, CitraPeak activates in just 30 minutes.
- Increase in thermogenic effect: In a cold condition test, surface temperatures were 5.4 °F higher among a CitraPeak group than a control, with users reporting increased sweating at room temperature.
- Nitric oxide pump effect: CitraPeak is broken down in the body into hesperetin (of which hesperidin is a glycoside), which has been linked to increased release of nitric oxide and related pump effects.
- Increase in blood flow: In another clinical study, CitraPeak was found to increase blood flow by 18% compared with a control.
Ongoing research is also exploring the product’s benefits in areas like V̇O2 max, recovery, mood and cognitive performance.
Already available in the US, CitraPeak will make its European debut at Vitafoods Europe (20–22May 2025 in Barcelona), where it will feature in a new pre-workout beverage concept. Prinova will exhibit at Stand #CC.B38.
James Street, Global Marketing Director at Prinova, said: “CitraPeak is a one-of-a-kind ingredient for preworkout applications."
"It offers all the clinically proven benefits of standard hesperidin – like increase in thermogenic effect and release of nitric oxide."
"However, for the first time it delivers them in a completely soluble form, so that the vasodilatory and pump effects of hesperidin are noticeable extremely rapidly."
"CitraPeak is a game-changing preworkout ingredient, and we’re delighted that its benefits are now available to active consumers in Europe.”
Sourced from citrus peels, CitraPeak® is clean, near colourless, near tasteless and odourless.
