Imuno-Strength® is a tasty natural blend of elderberry, rosehip and blackcurrant concentrates carefully formulated to retain the nutritive properties off the fruits. This delicious ‘syrup’ can be taken straight of the spoon or added to drinks. It can be taken by all ages from 5 years and upwards as a great way to boost the intake of powerful plant compounds called flavonoids. One type of flavonoid called anthocyanidins are believed to be particularly useful and are highly regarded by most nutrition scientists. Anthocyanidins are the dark red and blue colours found in many fruits and seeds and a huge amount of studies have been carried out to investigate their significance in relation to our immune system.
