Zylkène is a complementary feed for horses which contains a natural product, derived from casein, a protein in milk. It is a molecule well known to promote the relaxation of newborns after breastfeeding. Launched in April 2008, Zylkène has become a familiar product for veterinary surgeons, behaviourists, nurses and pet owners for use in helping pets cope when facing unusual and unpredictable situations or before occasions such as a change in their normal environment.

Zylkène is a product that can help support dogs, cats and horses in situations where they find the need to adapt their behaviour to cope. These include competing, travelling, clipping, hacking out or any situation that stresses your horse.

There are many ways our pets can respond to new and unpredictable situations and not all animals respond in the same way. Zylkène is palatable and easy to give; simply mix with food. Give just once a day.

Feeding Guidelines

Short Term Use: use for 1-2 days before the predicted event or change in environment. Some animals may need earlier supplementation (5-7 days).

Longer Term Use: 1-2 months

Horses up to 500kg: 1 sachet daily
Horses over 500kg: 2 sachets daily

Horses are often dosed for 2 days prior to a particular event, as well as on the day itself. Longer periods can be given, up to permanent, daily supplementation.

I bought this for a horse suffering with general anxiety with life. There were occasional days when I thought maybe she was a bit more chill but they were infrequent and random. I gave the whole course with pretty much no effect

I found it useful to take the edge off panic for new years fireworks at the neighbouring housing estate. He was still startled and wired, but not panicking and no unstoppable cantering around the field as before

Zylkene is works brilliantly. I bought 4 sachets for my mare as she had lost her confidence travelling in a new trailer. I had tried her in the trailer the day before giving her Zylkene and the short journey had not been successful with a very stressed horse. I gave her the Zylkene and took her to the beach. The difference was amazing, no sweating and hardly any movement in the trailer. It isn't the first time I have used Zylkene. I used it a few years ago when I took my horse to a local parade and it really helps relieve the stress.

55 Best Ever
Verified Purchase

I have owned my Haflinger gelding for eight years, he got so tense at shows he would just explode and sometimes bolt. I have tried almost every calmer out there. Zylkene worked we have done two dressage shows and been placed third at both competions. He is a fussy feeder but ate it no problem. It lasted all day where as other calmers wore off after a couple of hours. So onwards and upwards.

Tablet form

Cheryl Denholm


Is there a tablet form of Zylkene I can give my horse? She won’t eat powered substances.

Many thanks

  • VioVet Staff


Thank you for getting in touch.

Unfortunately Zylkene does not come in tablet form, it is only in sachets of powder.

I was just wondering if this product is FEI legal in eventing.

  • VioVet Staff

Zylkene is not on the FEI's banned substances list so is not tested for. However, any calming or performance-enhancing agent is not allowed, according to FEI regulations.
