this used to work well on my elderly riding mare when the formula was slightly different and I have been using the latest version on my retired racehorse and it appears to ease his discomfort although on really bad days I do resort to a sachet of Butaleve in addition

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.
