Fantastic product, we have used this for a long while now and have seen a big difference in our two oldies on it.
Maxine - 14/06/2023 14:41
this product helps keeps our ponies in top condition especially when they dont need too much feed
Maxine - 09/02/2023 11:55
dont completely know the outcome yet as early days but the pony eats it with the tiniest of feeds so positively good so far
Cheryl Anne - 15/12/2022 15:55
Excellent product that is palatable.  Only just started using to see a difference yet
Sylvia - 20/10/2022 01:05
Have been using this product for several years so that speaks for itself
Trusted Feefo Customer - 17/10/2022 15:42
The horse seems to like it. Always a good start. Since we are using it as a 'preventative', it is hard to tell how well it is working, but we have used it, alongside homeopathy,  since April to try to slow down the progress of cushings in an elderly mare. She did shed most of her coat and is a normal weight as we go into winter. I have ordered more.

Been using for my old boy for a few months he loves it and ooks well.
Pat - 25/08/2022 15:03
I use it for two oldies and have definitely seen and improvement in their coats.

Fed my old pony this for years and he’s still going string and continued to shed his coat
Laura - 18/07/2022 15:17
Great product, let down by the packing.
Fran - 20/04/2022 20:45
suits our aged shetland well
heather - 10/04/2022 21:31
Took several months to see a difference in my 22 yr old pony with EMS but wouldn’t be without it now.  He sheds his coat earlier and quicker, and his new coat looks fab. He is much happier in himself and more like his old self.
Carol - 07/02/2022 16:23
Products really do what they claim
Michele - 03/02/2022 08:09
It has really helped my mare and my old pony 32 years with cushions. My mare doesn't have cushings but her temper has never been good I have seen a remarkable change in her much more loving and tolerant
Rosemarie - 02/02/2022 19:22
My horse is just starting to respond with C-Plus . Early days yet but seems happier in himself
Trusted Feefo Customer - 31/01/2022 12:32
I have noticed an improvement with my old boy coat within 4 weeks.
- 05/01/2022 22:45
Early days but benefits showing
Michael - 15/12/2021 21:08
My gelding reacted badly to Prascend when diagnosed with Cushings, became a total psycho! Put him on half dose of C-Plus to see if his behaviour changed. Fantastic! Became his usual docile self with added bonus of energy levels returned & coat fell out quicker than the hubster's hair! Thank you Feedmark!
Laura - 04/12/2021 13:17
Been using this for over a year now, great product.
Rosemarie - 27/10/2021 20:20
My horses are happier in themselves with herbal remedies more natural
Kathryn - 21/10/2021 10:09
Very palatable, noticed a difference in how my mare's coat has improved.  Hoping for good results of blood tests in March when she is tested again for Cushings/EMS, will be interesting to see if the ACTH hormone levels have dropped.
Trusted Feefo Customer - 11/10/2021 09:52
My pony is insulin resistant and this product has helped to regulate his hormones and therefore get rid of his cresty neck
Trusted Feefo Customer - 22/09/2021 20:40
It helps my horse to feel great.
Sally - 17/09/2021 14:51
This seems to have really helped my mare.
Kathryn - 10/09/2021 10:50
I've been feeding this now since May 2021 and have noticed a real difference in my mare's coat.  I was advised to use this rather than medicate with Prascend when blood tests came back with high ACTH.  It will be interesting to see the next test results but I think this supplement is having a positive effect.  It's also very palatable as she can be a fussy eater.
Carol - 01/09/2021 16:41
The old pony I started feeding this to was showing slight Cushing symptoms since having C plus he is shedding normally again
Angela - 01/07/2021 21:44
Salem has Cushings disease and this product appears to help his condition.
Karen - 01/07/2021 09:08
good product does exactly what it says my mare has ems and cushings you wouldnt know looking at her thanks to this product
Kathryn - 28/06/2021 11:54
I am using C Plus for my 24 year old Irish sport horse to regulate her hormone levels as she is possibly cushinoid.  There are no issues with palatability and I was recommended this by an equine professional who has seen success with lower levels of ACTH over a period of time.  I have been feeding this for about 5 weeks now so I think it's too early to comment but I am hopeful that this will negate the need to medicate with prascend.
Valerie - 16/06/2021 20:13
I can see the improvement in my horse since giving C+
Caroline - 26/05/2021 08:56
Really helped my 24 year old Arab mare with her Cushing symptoms
Trusted Feefo Customer - 25/03/2021 13:20
Smells far too strong and the mare hates it and wouldn’t eat it.  So it’s now just sat there wasted.
Trusted Feefo Customer - 21/03/2021 20:50
Horse ate it without any fuss. Cannot tell if it made a difference as horse died last week
Sylvia - 18/03/2021 13:30
Absolutely brilliant.. have never had to call vet for a Cushing’s related consultation in 6 years
Trusted Feefo Customer - 10/03/2021 19:18
I purchased this as my pony had been drinking and peeing alot and was exercise intolerant as well as quickly putting on weight and hard to lose it, He was tested for cushings which was negative however, I have noticed he is brighter, he has stopped drinking so much and his bedding is normal
Trusted Feefo Customer - 20/01/2021 19:22
This product really helps my cob to cope with ppid
Trusted Feefo Customer - 06/01/2021 20:11
Improvement in syptoms , appetite and demeanor seen almost immediately. No palatability issues.
Alison - 06/01/2021 19:50

Amazing products, my horses look awesome
Jacqui - 30/11/2020 11:36
Very easy to order, my horse has cushings so I feel this supplement is supporting him well.
Rachel - 25/11/2020 20:14
Great product that doesn’t require a ‘loading dose’ great product for the older horse.
Valerie - 09/11/2020 06:34
Diane - 24/10/2020 19:26
Used both supplements for some time.  Really help me manage my pony.

Fantastic lifesaving product. For two of my old ponies improvements were since within a week. Will be feeding them this long term now.

My horse eats it all up 👍
Kathryn - 09/08/2020 21:05
I have noticed a difference in coat lustre and my fussy mare finds this supplement very palatable.  She is borderline bushings and I'm interested to see what the second blood tests reveal.
Trusted Feefo Customer - 26/07/2020 22:34
Outstanding results in a week and getting better still, so happy to see it working on my ponies!
Alison - 10/06/2020 22:11

2nd tub and coat is finally shedding on my 25 yr old mare. So far so good
Trusted Feefo Customer - 23/04/2020 19:52
A very Good quality product
Trusted Feefo Customer - 22/04/2020 20:26
I like the fact that you can try a sample of this product to see if your horse will eat it. Mine wouldn’t eat it to start with but I am gradually increasing  the amount and he is eating it.
Trusted Feefo Customer - 05/04/2020 08:07
Been using this for a couple of months. Great supplement, muscle tone is improving and he's shedding his coat already.
Jill - 05/03/2020 07:31
I have an elderly mare on this and she is much better in herself and outwardly.
She has low level Cushing and this has helped her maintain condition and helps her shed her coat.

Absolutely excellent and keeps my pony with Cushings in really good form.  It just seems to have that extra something that makes it special.
Karen - 27/11/2019 16:09
this product is a miracle
Trusted Feefo Customer - 27/11/2019 15:05
Bought C- plus for my retired gelding.  Smells nice and he's eating it.  No noticable changes in this first week but will keep feeding for a few weeks to set if this helps him.
Alison - 23/10/2019 16:45
I have used C+ for a while now, having used pure Chasteberry from another source for some years with considerable success in keeping my Cushings horse stable.  However, I have found C+ to be even better and I currently have a pony with Cushings who is extremely well in himself and keeping well which is all that matters.  I put this down to using C+ as he is not on - and not requiring - other medication.
Trusted Feefo Customer - 02/10/2019 22:10
Great value for money. Seems to suit my horses.
Trusted Feefo Customer - 02/10/2019 13:19

You sell natural products which I feel are very good for my horse.Delivery is brilliant every time.
Trusted Feefo Customer - 28/08/2019 20:50
I have used this product for a couple of years now for a pony with Cushings who reacts badly to medication.  He is absolutely thriving on C+ and I would recommend it to anyone with an equine in this condition.  I think it supersedes Chasteberry on its own - which I found to work very well but C+ is even better.
Trusted Feefo Customer - 28/08/2019 17:27
Great product as always and helps my horse no end.
Trusted Feefo Customer - 24/08/2019 10:40

Trusted Feefo Customer - 01/08/2019 09:27
I didn't expect to see any results so quickly but after two weeks, my 19 year old mare has a really shiny coat already, I am hopeful that after longer on the supplement, other benefits will show.
Trusted Feefo Customer - 31/07/2019 17:28
My pony is 31 years old and pre cushings. This keeps her fit and well and my vet says because she is on this she does not need routine medication.

Not been using it long enough to know if makes a difference.  My horse is not too keen on the taste but is now up to full dose after 3 weeks.  
Dose is very large to give in one feed - shame is not more concentrated
Anne - 08/05/2019 15:59

This Product has made a huge difference to my old horse after cushings diagnosis. Latest blood test showed marked improvement. Extra bonus is that although normally a fussy eater the horse loves it!
Trusted Feefo Customer - 10/04/2019 12:09
My 5 veterans have been on this for some time and I wouldn't use anything else.  They are well, their coats are looking good and are shedding well ready for summer  and shiny eyes all round -  including the 30 year old.

Mandy - 09/10/2017 12:19
My 38 year old boy has been on this for years, he was diagnosed with cushings 4 years ago and it was recommended to me by a friend from Feedmark to give it a try. I've never looked back since he is doing very well and not on any medication from the vets.

Nutrition Information

C-Plus™ is a blend of natural ingredients that not only support the pituitary gland, but benefit the all-round health and wellbeing of older horses and ponies.

The key ingredient is Chastetree Berry (Agnus-castus), commonly used to offer support to the pituitary gland, helping to maintain a normal and balanced endocrine system and metabolic function. This helps to keep hormones at correct levels to ensure normal immune status, coat shedding, and fat storage. In addition to this, Magnesium and Cinnamon support normal blood sugar levels, and antioxidants Vitamin E and Selenium combine with the natural health supportive effects of Rosehips which, along with immune-supportive Astragalus, optimise the health status of the horse. Further ingredients add extra support for older horses: Seaweed helps to encourage normal fat distribution, and prebiotic Brewer’s Yeast and soothing Mint ease the gastrointestinal system and support efficient digestion.


Micronised linseed, Chastetree berry powder (15%), Brewer's Yeast, Seaweed, Rosehip shells, Magnesium oxide (5%), Mint leaves, Maize meal, Cinnamon, Astragalus.
