What Our Clients Are Saying

  • Ashlee Bond International Show Jumper

    SynChill has been a game changer for me and my program! I can’t express how wonderful this product is. It helps the hot/ nervous/ spooky/ sensitive ones focus and stay calm without taking their quality away! It’s super easy to give to the horses and they seem to like it as well! I can’t survive without SynChill! It will forever be a part of our program!

    We are so happy to have found a product like this—it has made the biggest difference!

  • Mark Glatt Multiple Graded Stakes Winning Trainer

    The products are very effective and cost friendly. In particular, SynAir.

  • Lorrie Canaday Galway Farm

    We at Galway Farm love the SynNutra products! Specifically the SynChill and GastroMend. SynChill is so easy to administer, the smaller tube is great, leaves less residue and works! Our horses really seem to relax. The GastroMend has made a significant difference in several of our horses’ demeanors! WAY happier and more relaxed about life in general and happier to do their jobs! Definitely products worth trying and the customer service is fantastic!

  • Laura Hansen La Cresta, CA

    My nervous green 5 yr old jumper did two perfect clean rounds at Thermal today…1st time EVER in jumper class, thanks to SynChill! So happy!

  • Karen Klawitter CEO, SoCal Equine Foundation, Inc.

    I recently used SynChill on my eventing, trail horse. What an astounding difference! His character changed dramatically! He went from being aggressive and hard to work with to standing still to be saddled and even stood still to have his EZ boots put on. AND on the trail he was a real “trail” horse. I can’t wait to see the difference at his next trial event!

  • Howard Zucker Thoroughbred Trainer,
    Santa Anita, Del Mar

    The more I use it, the better I like it. I\'ve just switched my last 2 Gastro Gard horses on to this. HUGE savings for the owners!! No drugs, completely natural.

  • Jeff Metz 4 time leading trainer at Emerald Downs.
    Trainer of multiple stakes winners at Emerald Downs and Turf Paradise
    Trainer of multiple State Champions in WA

    I used Syn Air on bleeders and horses that get mucus a lot. It definitely gives a horse energy and the ability to breath the best possible. have been using for a couple of years now and am very happy with the products results.

    Horse Racing, Naturally

Nutraceutical is the product of smashing "nutrition" and "pharmaceutical" together, becoming representative of finding a natural pathway to better health, performance and treatment of disease. According to the National Nutraceutical Center, Nutraceuticals are made from herbal or botanical raw materials. More than 40 percent… …
