Prinova has launched its clinically supported pre-workout ingredient CitraPeak® in Europe. 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-workout 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:

• Increase in physical output: Research shows that CitraPeak® helps increase energy and physical output
• Rapid release: Over 100,000 times more soluble^[1] and 347 times more bioavailable than standard hesperidin, CitraPeak® activates in just 30 minutes.^[2]
• 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.^[3]
• 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^[4] and related pump effects.
• Increase in blood flow: In another clinical study, CitraPeak® was found to increase blood flow by 18% compared to a control.^[5]

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 (20th to 22nd May 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 pre-workout 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 pre-workout 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.
