Freeway Gold is a fast absorbing liquid supplement containing herbs such as eyebright and thyme to help maintain an efficient respiratory system. After initial use, you could go onto its dried equivalent Freeway (we do not suggest you give both together). We are seeing more horses affected by summer allergens and winter dust and the Freeway range would be ideal to use under these circumstances.If your horse was more troubled by crops and allergens, then our Shake No More Gold would be more appropriate. Do contact us if you are unsure which supplement to use.
