What is RetaFit – and why is it different?
RetaFit combines niacin (vitamin B3, 16 mg = 100% NRV) with a plant base of raspberry fruit extract, green tea and guarana plus N-acetyl-L-carnitine and a touch of caffeine – vegan, gluten-free, GMO-free and made in the EU. The best part: its strongest promises are officially authorised claims* – niacin contributes to the reduction of tiredness and fatigue, to normal energy-yielding metabolism and to the normal functioning of the nervous system. The perfect base for a day that starts well.
