Both Flexicose and Syn-flex are fine products. They each contain 1500 mg of glucosamine, but some of the additional ingredients are different. Therefore, many of our customers choose to get the best of both brands by alternating between the two. Although Flexicose has a grape flavor and Syn-flex is Mandarin orange flavored, most users mix the product into a drink. We prefer ours in orange juice. And most dogs don’t care which they receive.

Although we started with Synflex liquid glucosamine, we now use both products in our home. My old dog, Storm, had arthritis in his later years. We discovered Synflex while looking for an alternative to the Aspirin (which almost killed him), and Rimadyl (which we had read of the potentially bad side effects). Here is the Aspirin for Dogs article about Storm’s near death experience with it.

We started selling Synflex about 2 1/2 years ago after we saw how great it worked for Storm. And about 1 1/2 years ago we tried Flexicose liquid glucosamine, liked it, and started selling it too. Now we open one bottle at a time and alternate brands. When we use up a bottle of Flexicose, we’ll open a bottle of Synflex next. We don’t see any difference in their effects. Although many of our customers swear by one brand or the other, I think it probably only matters which they start with. Most people will stick with what they started with if it is working for them.

Although we feel the positive effects of each are the same, there are some differences in each product some people may prefer. Flexicose has a grape flavor and needs to be refrigerated AFTER it is opened. Before opening the bottle you may simply store it in a cool place in your home. Synflex 1500 has the new mandarin orange taste and does not need to be refrigerated after opening. Some customers prefer one flavor over the other. And although some of our customers do take their glucosamine “straight”, we prefer it mixed in juice. In fact, you can read about our morning drink here.

So when the question of which brand to purchase comes up, I really don’t have a definite answer. But keep in mind that many of our customers will specify in the comments section of the shopping cart that they would like to have some of each brand. For example, a customer may order 6 bottles of Flexicose or Synflex and specify they would like to have 3 bottles of each. They are the same price, so you may mix and match any way you would like.
