T is on this now instead of MSM - as this product contains MSM. Not sure if it is benefitting her more tham just MSM, but early days yet to assess fully.

unsure quite how effective this is in relieving my elderly TB's discomfort, certainly appears to offer some relief
Trusted Feefo Customer - 02/03/2022 19:54
I have been using Zerobute for years but the last supply smelt different and the £139.00 was only half full. It has never been like that before!
Joanne - 22/02/2022 19:52
When my farrier reshod my horse last week he said I should start riding her again after 10 months. I've been using Zerobute since before Christmas.
Trusted Feefo Customer - 17/02/2022 08:08
My 20 year old thoroughbred is much more comfortable on his hinds with arthritic changes since using zerobute would definitely recommend it

Just started using Zero bute and so far I am very pleased with the results. Daisy has been lame for 9 months and under veterinary investigations. She is still lame but must feel better as she jumped out of her enclosure. I will continue to feed Zero bute during the winter and fingers crossed she will feel better.

This product seems to be really improving the movement and general well being of my veteran Irish Draught cross. He is so well in himself and spends most of his time in the field getting down, rolling enthusiastically, getting up, shaking himself down and taking himself off for a short canter!

Zero bute keeps my old retired mare moving easier

Excellent when occasionally needed for my ex polo pony.
Trusted Feefo Customer - 03/07/2019 14:29
This does really work and is fast acting. Hesitant to use all the time because of the devils claw in it which could cause ulcers? And that you can't compete on it. Horse doesn't like the taste, so have to try disguise in feed.  However I would recommend.
Clive - 19/06/2019 14:19
Not sure yet.As only just trying it

Amazing stuff! I was at my wits end trying to make my children's old pony more comfortable. Even the vet was stumped as Bute hadn't helped. After a week of use she voluntarily cantered across the field with a few bucks thrown in for good measure. Millie hadn't got out of a shuffle for over a year

Nutrition Information

Zerobute™ contains herbs and natural compounds that provide a safe and effective way to soothe the musculoskeletal system, maintaining mobility. The well-known properties of Devil's Claw provide the active constituents harpagocides, which help to keep the horse comfortable. This is complemented by the herb Chamomile, which helps to keep muscles relaxed, as well as Yucca and Meadowsweet, all of which have well known soothing effects. Methyl sulphonyl methane (MSM) is a source of Sulphur, necessary for the production of collagen and connective tissues, and Celery seeds have a warming effect so are ideal to feed to horse’s that are tired or run down as a pick-me-up. With a complex chemistry, this combination of herbs and plant extracts are naturally soothing and comforting.

For optimal mobility support, Zerobute™ can be fed alongside one of our high specification joint supplements, Best-Flex HA® or ExtraFlex HA®, and is safe to feed long term. Ideal for older horses or younger horses that have been worked hard and have a bit of wear and tear.


Methyl sulphonyl methane (MSM), Devil's Claw root (29%), Meadowsweet, Celery seed powder, Chamomile flowers, Yucca.

Zerobute™ is safe to feed on a long term basis. Zerobute™ is not recommended for horses where gastric ulceration is indicated due to the effect of Devil's Claw on the digestive system.

Feed supplements should be fed according to body weight. Introduce to the horse's diet gradually, splitting between feeds (when applicable).
