Invia, a mental performance drink mix supplement developed with Cognizin citicoline, a branded form of the brain health nutrient, citicoline, is now available in two calorie-free flavours; mixed berry and tea lemonade.

Invia was formulated by a neuropsychologist Robert Paul to enhance concentration, and tests conducted showed it increased participants' performance in visual learning, reaction time, and processing speed.

Paul said: "When I developed Invia, I was looking for product that could elevate my performance as a professional, husband and father.

"Invia's formula is based on clinical research, the industry's gold standard."

"Invia's formula is based on clinical research, the industry's gold standard, because I wanted a product that I could use every day without compromising my health or integrity."

The ingredients of the drink are formulated at precise doses. Studies published indicate that the main ingredient, Cognizin citicoline, improves focus and attention.

The new supplement contains vitamins E, B6 and B12, along with a combination of caffeine and ornithine.

This combination is found to result in a willingness to work, an improved mood, and better concentration when compared to caffeine alone.

Invia is currently available for purchase on the brand's website in three different packages; Standard, Featured and Preferred, which are customisable by flavour.
