Good product , easy to feed and gives me peace of mind as my horse is on limited grazing which I know can be hard on the gut .

55 Good for stabilising a sensitive digestive system.
Verified Purchase

By on 15 February 2020

A very useful additive for aiding stability to my horse's delicate digestive system.
We are very careful to feed 'straights' as commercial feeds seem to add too many subtle extras - usually involving sugars and soya etc which exacerbate an already compromised and delicate digestive system. Feeds and hay are carefully evaluated and timed, and the GastriAid is good for balancing the right nutrients, and we have a much happier and comfortable horse with whom to enjoy working and riding.

I have had my horse on this since he was diagnosed and treated for ulcers. Alongside ensuring access to constant forage and keeping feeds molasses- and sugar-free as much as possible to avoid acid reflux, this supplement has helped my horse to stay happy and healthy.

Can gastriaid be used along side of pink powder?

  • VioVet Staff

Hi Wendy,

Thanks for your question.

I have spoken to NAF who assure me it will be fine to feed both together.

Hope this helps.

My horse has two feeds a day, can the daily dosage be split between the two feeds or is it best fed in one of them for the best results??? Plus he is unable to have alfa alfa a hes allergic, would it still be ok to use this??

  • VioVet Staff

It is best to divide the daily dose between the 2 feeds he has each day. It should be fine for him with his Alfalfa problem.
