SynChill from SynNutra is a pleasant-tasting, all-natural equine calming gel meant to help your horse focus calmly on the job, whether that's on the racetrack, in the show ring, out on the trails, or schooling at home. SynChill preserves your horse's mental clarity, unlike sedatives and tranquilizers, while minimizing their 'flight' response. It's also the only product on the market to incorporate 5-HTP (5-Hydroxytryptophan), a natural anti-represent and a precursor to serotonin. The unique blend of this amino acid, with Vitamin B6 and Melatonin, will maximize serotonin production and maintenance and allow for your horse to perform stress-free. You'll love that this gel won't take away from your horse's physical capabilities, and with your partner's improved mindset, you can maximize your ride!
