These tasty natural honey and lemon flavoured lozenges dissolve in the mouth to provide a steady release of zinc vitamin c and bee propolis to the throat membranes. The zinc is present in the citrate form because citrates are known to be readily absorbed. Zinc contributes to the normal function of the immune system as does vitamin c. The vitamin c is presented in the ascorbic acid form. Lamberts® zinc plus lozenges can be used as a lozenge or as a zinc supplement. Indeed these lozenges are ideal for both adults and children who find tablets and capsules difficult to swallow. Aspartame free.
