Prinova’s CitraPeak® brings high-bioavailability citrus peel ingredient to the pre-workout market

U.S.A. – Prinova, a global distributor of functional ingredients, has launched its clinically supported pre-workout ingredient CitraPeak®, the first 100% soluble form of hesperidin, sourced from citrus peels and with vasodilatory and pump effects.

Hesperidin is a bioflavonoid that occurs naturally in citrus fruits and has been associated with antioxidant, antibacterial, antimicrobial, anti-inflammatory and anticarcinogenic properties.

According to Prinova, the hesperidin In CitraPeak® is bonded to tapioca starch, making it 100,000 times more soluble and 347 times more bioavailable than standard hesperidin, allowing rapid activation.

CitraPeak reportedly has a widely supported range of benefits spanning the earlier mentioned rapid release within 30 minutes, increased physical output from elevated energy levels, and increased blood flow.

In further tests, one including cold conditions, surface temperatures were 5.4 °F higher among a CitraPeak® group than a control, with users reporting increased sweating at room temperature. This highlighted its impact on thermogenic effects.

“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,” James Street, Global Marketing Director at Prinova, said.

In several studies, Nitric oxide has proven to be a significant blood flow and mitochondrial respiration modulator in physical exercise. 

Several researchers have suggested that nitric oxide could contribute to increased oxygen delivery to the muscles, consequently enhancing athletic performance and reduced soreness after workouts.

Ongoing research is also exploring the product’s benefits in areas like maximal oxygen consumption (V̇O2) max, recovery, mood and cognitive performance.

“CitraPeak® is a game-changing pre-workout ingredient, and we’re delighted that its benefits are now available to active consumers in Europe,” James added. 

Already available in the US, the clean, near colourless, near tasteless and odourless CitraPeak® will make its European debut at Vitafoods Europe (20th to 22nd May 2025 in Barcelona). It will feature in a new pre-workout beverage concept.
