This has completely settled my mare. She had separation issues when in season. This has gone
She is much quieter to handle
She is a fussy eater however no issues with this product
I would thoroughly recommend

The Chastetree Berry powder has really helped my elderly mare since she was diagnosed with Cushings disease. She is less hormonal and has a brighter outlook than before. She shed all her coat this year by herself and is currently looking fantastic. I'm sure the CTB powder has helped her in many ways and i shall continue to use this supplement in her daily ration.

Everyone can see the difference in my grumpy gelding would highly recommend. Doesn’t overly like the taste but mint and garlic does the trick

I have a very hormonal mare, would this stop her coming into season?

Chastetree Berry won’t stop your mare coming into season, but it can help to maintain more stable hormone levels through oestrus, which will keep behaviour more settled. For the best support for hormonal mares we recommend that you look at Hormonease.

My gelding is riggy, and at times his behaviour is very stallion like, is this only used for mares, or can it help geldings too?

Chastetree Berry can help to maintain normal hormone responses, and can be fed to riggy geldings as well as hormonal mares. It is included as an ingredient in Feedmark Hormonease.

My pony struggles to shed his winter coat, I was told this supplement could help?

For older horses and ponies that may struggle with coat loss, this herb can help to maintain normal shedding patterns. If you have a horse or pony that has been diagnosed with Cushing's you may be interested in C-Plus™.
