    The Mare mix really works wonders on my mare. Sweet calm and not spooky when on Mare Mix.

    I absolutely recommend Herbal Horse to any horse owner! I’ve used the mares mix before for a very difficult mare when in season and was shocked with the results. She is much calmer and has a better attitude when its given to her. Sure all the other products will have the same effect!

    I have used almost all of your products except the Endurance one. All of my experience were amazing. Most recently I have used the Mare mix and it worked like a bomb within a day! Love your products!

    The Mare Mix has helped with both my easily distracted OTTB mare and helped my rescue mare settle better in my care.

    The Calm Mix has been a huge help overall with my OTTBs – both coming to me off track and to help settle them at shows.

    I don’t leave my yard without ensuring that both Calm and Immune mix are packed in the feed for shows – be it 1 day or week-long show – I can always be guaranteed with the quality of both the products and service!

    Beryl Shuttleworth is always just a message away for either advice or emergency supplies, in the past 3yrs of being a loyal customer I am always quick to recommend Herbal Horse to anyone for supplementation – be it competition or happy hacker horses

    My very mare-ish mare has been on both Calm Mix and Mare mix for the last 5 days and I just had a 2 day clinic with Adriaan van Wyk and my horse was the best ever. The most relaxed, focused and non-mare behaviour ever. Very impressed! 🙂

    Just to provide a bit of background on my mare – Lissy had 4 foals before the age of 10 so I am assuming she was used as a broodmare. When I bought her, the Vet thought she was still in foal but after a scan was done, she was in fact not. Turns out she had just been taken from her foal.

    So what I discovered as I never had a mare that had any foals was she was prone to come into season every week. She was in a right state all time very demonstrative when in season compared to other mares. She was very very tense to sit on and everything got heightened noise smell. Attending events she was on high alert.

    So I started a long and expensive process of trying supplements. Now when I got a back person out one of the main issues Lissy had was her pelvis due to not just the number of foals but how often she came into season resulted in her pelvis in constant tilting position she she suggested I use Slut Mix this would regulate her cycle and help with coming into season.

    I used this together with relax me and she then regulated to every month. I didn’t see her relax to much but at least only once a month she got dizzy when in season.

    However this is a costly supplement and I also was advised sometimes supplements should be used then stopped and let the horse settle.

    So I looked at other options and tried them and then found you.

    I am not riding this mare the last few months the woman that runs yard is and she has said she sees a massive different to her attitude much happier in herself.

    i have noticed she has better focus at shows as I ride my other mare at the same events and watch this mare closely.

    She still has a spook but she has better focus and seam less demonstrative when in season. so all in all good result and will continue to use it and will let people know about your products as well.

    Thank you

    On mare mix there are only minor indications of heat. Small signs plus my calendar confirm she’s in heat. She shows and flirts with the boys and they flirt back (when normally they could care less about her). Lots of tail lifting and bums at the fence. However to ride she only shows some minor signs of irritation but she’ll bend and use her back and be relaxed.

    Off mare mix (this cycle) she’s totally preoccupied in rides with the rest of the horses, nickering while I’m riding to other horses in the ring, and she braces her back and I have to work my tail off to get her to relax into the contact and use her back and bend. I try to keep the rides light during these times but since the mare mix I could ride as usual.

    🙂 Happy!

    The Mare Mix on trial has also yielded wonderful results. My mare has suffered terribly with her oestrus cycle which often resulted in having to call the vet out, or medicating her with something to manage the pain. She has been on the mare mix approximately a month and although it is still early days, her mood has vastly improved (the other horses have not been maimed or mutilated when walking past her as she grazes – I take this is a plus!). My riding instructor who schools her has also said she is much calmer and easier to work with. I have noticed that she is more calm and relaxed and does not spook as easily. This is definitely a product I will keep her on (for my sanity and the safety of all the other horses!).

    At the end of September 2011 we acquired Goldi, an incredibly strong-willed but gorgeous dun mare.

    From her previous history it would appear as if Goldi was passed around a little, but never settling with the right person. My 10 year old daughter, Shea-Lee, and Goldi just clicked – both stubborn, strong willed and fiesty at times!

    When in season Goldi can be a bit difficult – She likes to snatch and tank-off, can be a bit girthy and bucks. When offered the opportunity to test run The Herbal Horse Mare Mix then we jumped at the opportunity!

    Within a week of being on the Mare Mix the change was evident – Goldi became more focused and willing to work – So much so that they took both Grand Champion Novice Showing titles at the last graded showing!
    Unfortunately we recently ran out of the sample product and swore never again!!

    I must tell you that there was a remarkable difference in our mare when she was on your mare mix. Our girl is quite the tart at the yard (she is extremely pretty though) and seemed to be in season 22 days a month. Although she has the sweetest nature, she is very moody a lot of the time often just wanting to get back to her friends. We started her on your mix and almost immediately she changed. She was a load calmer and did not just want to get back to the herd. It was a pleasure. A changed horse. When she went off the mix she has now appeared to have the same old ways again. Cant wait to see the difference again and i will let you know. Think i am going to put her on every second day.

    There is a marked improvement in my mare – the Mare mix arrived just before her bad stages at the end of summer – I haven’t had her tying up and feeling stiff and sore from cramps. She is and always will be moody but I have noticed a marked improvement in her demeanor when I know she is in season. She had one moment at NRA where she was flirting with all the boys but I cant say I blame her but she was easy and manageable and was able to do her job still and wasn’t her usual hormonal self.

    Past weekend at CVRC she did one of her best tests and was cool calm and collected – I am OVER THE MOON.
