Fantastic gut supplement
Verified Purchase

By Karen Nelson on 23 November 2025

I have tried a lot of top branded products as a daily supplement to keep my horse happy after being diagnosed with hindgut issues and NAF GastriAid is the only one that has worked. I have been using it on my TB for 3 years now and it is keeping his hind gut settled.

Q & A

Below are some recent questions we've received regarding NAF GastriAid for Horses, including answers from our team.

18 September 2025 at 9:28am

Number of feeds

Laura

My horse is now on the maintenance dose, can this be given in one feed a day?

  • VioVet Staff

Ideally, one dose should be spread across multiple feeds in a day.

Protein amounts

Kate

I note the protein measurement is 7.1% but how many grams protein is delivered in 3 scoops/measures please?

  • VioVet Staff

Feeding guidelines recommend administering 3 scoops (60 grams) per day for maintenance in horses. Therefore, each scoop (20 grams) provides approximately 1.42 grams of protein (7.1% of 20 grams). Consequently, 3 scoops would deliver about 4.26 grams of protein daily.

Giving sporadically

Emma

Can I give this to my pony a few days before a comp and do not give permanently?

  • VioVet Staff

Yes this product is FEI/Jockey Club Legal so is safe to use around competitions. You should follow the dosing guidance in regards to when to feed. The loading period is 3 to 10 days of a higher loading dose so it is recommended to be beyond the loading period and into the maintenance period for the best effects to be seen.
If you ensure a good loading period is carried out and your horse has just started the maintenance dose for when the competition starts then this should be appropriate.

Gastriaid

Wendy

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.

Dosage

lisa

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.
