The nutrients featured in Mini Drops Immune Plus serve more than one purpose. Zinc, Vitamin C, Vitamin B12, and Folic Acid all support the healthy functioning of the immune system. Vitamin B12 and Folic Acid also help to reduce tiredness and fatigue. Elderberry is also added at a rate of 100mg per dose, and the fact that it's a blackcurrant liquid means the supplement is delicious while containing no artificial colours, flavours, or added sugars.
