Prinova’s CitraPeak launches in Europe

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-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: 

• 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 (20^th to 22^nd 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.
