Did you know that 70% of immune cells are found in the gut? Data from epidemiological studies show that diet influences the quality of the immune response. More precisely, for an effective immune defence, it is essential to act on the different players of immunity: white blood cells, antibodies and inflammatory agents. Immune health is one of the most popular health benefits in the food supplement sector. As an immunity food supplement manufacturer, we provide nutraceutical solutions to help you stand out in the immune health market.

ImprovD3 logo immunity

Cholecalciferol – Camellia sinensis L.

This patent-pending ingredient combines vitamin D3 and green tea extract for a complete action on immune health.


Vitamin D, in its active form calcitriol, plays a critical role in immunity, enhancing both adaptive and innate immunity. Because vitamin D needs to be activated to be effective, we have developed ImprovD3™, a patent-pending combination of vitamin D and green tea that has been shown to promote vitamin D activation.

Scientific evidence

Green tea polyphenols have been clinically proven to boost the immune response. In addition, a proprietary study highlighted the synergy between vitamin D and green tea to increase the production of calcitriol, the active form of vitamin D, by +17% compared to the ingredients alone.
