Zylkene testimonials:

Amanda Skinner and Ollie

“We have used Zylkene since Ollie was a puppy, he's a big nervous wreck when it comes to vet visits and Zylkene is our saving grace! We love how easy it is to administer, just pop open the capsules and mix it with his food. He doesn't take tablets well so Zylkene is absolutely perfect!  We always make sure we have some in the house just in case and wouldn't be without it, we've tried other calming products but this is by far the best!!”


Jackie Flack and Lionel

“We adopted a 9 year old lurcher last year and because of his previous lifestyle he suffered with severe separation anxiety, especially at night time. Despite allowing him to sleep in the same room as us he still panicked when he did not have contact with us. We have been using Zylkene now for a couple of weeks and the difference is amazing, we first used 1 tablet a day but now only need 1 every other day and we are hoping to reduce further. He is so much more relaxed now and we are all getting much needed sleep!”
