very good product. Has helped clear my horse's mud fever.

Superb product, good value for price.

Great for the flys , helps the respiratory system along with the immune system, nice resealable packet

Love it, really helped my boy,
Have found his coat shines and his skin looks so much better, he really looks amazing , was delivered quick to .

Within a week of feeding selenavite my mare is perkier and eating up well. Because of molasses I would suggest using pump attachment to bottle yo dispense otherwise a bit messy

The cap and the snood are both great, extremely good quality and value, will certainly buy more products, especially if you did a men’s coat or jacket thanks, Mark

I use this for my 30yrs old Highland mare who has arthritis and it gives her more mobility.

Excellent quality item at a great price. Fabulous communication and fast delivery. 10/10

My highland pony suffered from discolouration around the muzzle and eyes, we had tried other copper supplements without success. After researching copper products decided to give this one a go and it started to clear up within 3 weeks! Mac looks amazing 🤩

This is an amazing product! I have seen a positive difference in my mare within 4 days of use. I would definitely recommend Gastro Mag.

Used for traveling and it worked on my horse a treat. She was super calm the whole way.

Love this

I expected a few gentle exploratory licks on his first evening with the ball … wrong! He found a way of jamming it and has gnawed it with obvious great pleasure!

Excellent product

My boy, who is young and can be sharp and spooky, is much calmer since being on this for about 4 months. He seems more calm after starting off rather anxious when I got him last year.
