How long can my horse be on clop for he is a 16.2hh

  • Veterinary Advisor

Valerian based calmers such as CLOP are very safe and can be given for as long as required. Many horses take this kind of supplement daily long term. If you intend to keep your horse on CLOP long term then you may find that you can give a lower maintenance dose and still have the same effect. Though this will depend on your individual horse.

What are the ingredients and amounts of this calmer
What is the strength of the valerian?

  • Customer Service Manager

The ingredients of the product are linseed oil and valerian.

As it is a natural product, it is difficult to determine how strong the actual valerian product is itself, but it is in the product at 0.5%

Is there magnesium in clop liquid calmer

Jo Curran

I could not find what is in your calmer. Could have I detailed analysis please?

  • Non-Executive Director

This calmer is based on Valerian compound (a herbal product which is regarded as safe and effective as a calming agent, but is not permitted to be used in competition horses). It is not based on magnesium for its effect.
