  Highly Recommend Foundation

  I have been using Foundation for a while now for my horse Yogi and he is looking amazing with a super shiny coat even in winter. It's such a simple addition that is also cost effective, highly recommend! Tina is also super helpful with nutritional advice

  All the ingredients you need at a good price

  I've either tried or had a very good look at a number of other options but HIHO Foundation is superior as far as the ingredients go. Everything is in there and in decent amounts. And on top of this it is the most cost effective product I can find. Recommended.

  Great products

  My mare is on HHIO foundation and support and it really settled in her work and a pleasure to be around! She is also no longer girthy (only mildy when in season) which is a big improvement! Highly recommend.

  Outstanding!

  I purchased this upon recommendation of the person I leased my horse off. My boys coat is shining and he absolutely loves the taste!

  Would not be without!

  Been using this for years and would never change. Great coats, hooves, health—they all do very well on this. Mud fever markedly reduced!

  Great products!!

  We love Healthy horses inside out products!! Recommended by our farrier Tara. We now recommend these products to others. We follow one of the feeding programmes recommended and it keeps it to a basic and cost effective feed plan for all our horses. They get a small daily hard feed with plenty of grass and hay fed also. One of our horses has been on foundation for 2.5years - the shine to his coat gets lots of compliments from others - he is a 16yr TB - who wasn't in great condition on arrival We just purchased a new pony (elderly german riding pony) who we have started on this product also - 1month with us so far We brought anther horse (12yr TB) last year who we give performance but he will move to foundation when the time is right- he was very skinny and looked shabby on arrival - he looks amazing now

  Foundation

  Brilliant mineral mix. Been using for ages now well over a year maybe two .Horses look great and some great advice about base feeds etc . My horses were initially suspicious of tbe taste but all adapted over a month or so and gobble it up now . Great company to deal with ��

  Loving HHIO Foundation

  I absolutely love how thoughtful you are and so generous with the feeding info. It has been enormously helpful to me in getting Toto’s diet balanced. He is coming through the winter looking great! My wonderful barefoot hoof trimmer, Chelsea, said at his last trim that his feet are looking really great – way better than most of the other hooves she trims! I’m very grateful to you for sharing your experience and research into a balanced feed. Together with your Foundation, Toto gets a cupful of oats (cooked the night before); ground flax seeds; ½ cup copra (soaked); 2 tablespoons of NZ sea salt; 3 big scoops of lucerne chaff and I have added a tablespoon of desiccated coconut!

  So Happy

  5 ⭐️ plus! It’s always unfortunate to have to get the vet out , and net result Tōtara is going to be absolutely fine (hurt her leg) . But when the vet’s first comment is : Gosh she is in excellent condition, look at that shine! Then: She is so shiny, is she covered all the time? (No, she’s covered at night, but she’s on HHIO) And after treating- What’s her feed regime? (The vet was watching her munch in to brown top hay from the feeder- ie pretty much zero nutritional value) I told her Hekeao whole food muesli and HHIO Foundation and Support. And that I was particular about the Recommended dosages Plus salt. The vet wanted screen shots of the products so she could read about them. She was very impressed with Totara’s condition. Which made me feel happy! Tōtara has hunted all season, (our first season for both of us). It’s been full on and to come out of it with her so healthy and shiny is thanks to HHIO! So yeah. Very happy. But I’ve been using HHIO for close to a year now? Had my previous horse on it, thanks to Natalie De Caro for recommending and giving me samples to try.
