Morning Sarah. A disappointing response & one which we take to heart. With supplements, sadly, not all will be successful with all animals treated. Having said that we would urge you to continue using the product until at least your current supply is exhausted. The last person who gave us a low scoring review wrote a couple of weeks later to say that she had changed her mind completely, would be re-ordering & please could she update her initial response.
You may not have read this excerpt from our website so we paste it below, just to give you the technical side of things
Nicotinamide works in two different ways. Firstly & most well known is the dampening down of the immune system & therefore the urge to scratch/rub itchy parts. Secondly, it works to thicken the skin. The first effect - relating to the immune system - builds up quite quickly, in a matter of days, while the second takes effect much slower. The skin’s thickening is caused by increasing numbers of fat cells it contains & this process is ongoing, it can take a month or more.
We wish you all the best in finding a solution that works well for your pony.
