What is Syn-flex?

There is often talk about glucosamine supplements in the Tripawds Discussion Forums. Since Syn-flex liquid glucosamine was one of my daily supplements, and my people believe it helped with my orthopedic issues, we thought we’d share what we know about it here.

Syn-flex is an all-natural product that is not known to interact with any drugs or medications. It is a premium glucosamine arthritis liquid supplement made in the USA since 1999. The formula for pets is identical to that for humans but includes a tasty beef flavor.

Syn-flex uses only pharmaceutical quality liquid Glucosamine, the highest quality available. It has no fillers like many Glucosamine pills, and as a liquid it delivers maximum absorption and rapid pain relief. Syn-flex has no dangerous side effects such as those with NSAIDs and Cox-2 Inhibitors.

Here is a breakdown of one 1/4 oz. Syn-flex serving:

Certified Ingredients Per 1/4 oz. of Syn-flex

  Glucosamine HCL and Glucosamine Sulfate

Please note that “Shark Cartilage” is not actually derived from shark fins. It is merely an industry term for shellfish exoskeleton. We know – we were concerned, so we asked when visiting the Syn-flex factory in Florida. Visit their website for specific details about all Syn-flex ingredients.

Here’s one customer testimonial the fine folks at Syn-flex passed on to us …

Our 12-year old min-schnauzer was having a real hard time walking and trying to go up and down our steps to go outside. The vet gave him an arthritis medication but I was reluctant to use it. I checked all the information and testimonials on Syn-flex and decided to give it a try. It seemed to work within 2-3 days with our Bunky. Where he could barely walk before, he was almost running with the other younger dogs within a week.

At the same time I was using the product for my arthritis in my knee and felt a huge improvement immediately. When we ran out of the product I didn’t re-order, thinking I could some like products from the pet stores. No way did they work the same. I just received my first re-order of Syn-flex, Bunky has taken 3 doses and is again his lively, playful self that he was before when he took it. THANK YOU for this wonderful product!
