In a double-blinded placebo-controlled human clinical study1, the Memory Complex demonstrated an impressive improvement of 10.1% in total memory. This versatile ingredient can be incorporated into tablets, capsules, soft gels, sachets, gummies, bars, drinks, and syrups.

Christian Steinle, Head of HARKE Nutra, one of the Business Units of HARKE Pharma GmbH: “I am convinced by the scientifically proven combination of L-theanine and fructooligossaccharide, which naturally promotes cognitive performance. For me, our Memory Complex is a real booster for clear thinking and a strong memory.”

The newly acquired Memory Complex has already been commercialized by brands in Germany and the UK. Under HARKE Pharma GmbH's control it is expected to have further launches across Europe and North America over the next 12 months supported by HARKE nutrition specialists who work closely with customers to develop formulations, from initial concept development to regulatory guidance and customized product delivery. The product will be a significant addition to Harke Nutra's diverse range of functional ingredients which already includes antioxidants, vitamins, minerals, plant extracts, and food additives.
