  1. Louise Harkin

    A fantastic supplement that has aided my Boys weight, condition & energy.
    Proved pricey as he needed larger quantities but did its job.

  2. Vicki Sedgwick (verified owner)

    A truly fantastic supplement, has allowed my metabolic boys weight gain safely whilst calming his stomach, proved very pricey as was required to be fed at the top scale of recommendations to allow weight gain but has proved very successful. I now feed him at 150g per feed three times a day and hoping he will maintain his weight but may need to increase again as the whether changes.

  3. C Belshaw

    My horse has hind gut issues, I was using gut restore and liquid gold. Since switching to ulsax I have noticed even more of a difference. Not moody and can touch anywhere around stomach and hind end, also moving much better.
    I use it as a supplement not feed.
