Potter's Herbals Malt Extract is a  traditional malt extract combined with cod liver oil, which is a source of vitamin A and D. Vitamin D contributes to the normal absorption of calcium and maintenance of normal bones and normal muscle function.Cod Liver Oil has been valued by generations as a natural source of vitamins and is highly recommended as a supplement - but many people dislike its distinctive flavour and find it hard to digest. Potter’s use a special process to combine Cod Liver Oil with Malt, to create a pleasantly flavoured product which is also easy to digest.
