Synflex 1500

Powerful Liquid Glucosamine

Liquid Glucosamine Formula Synflex 1500

Syn-flex® Original formula is a powerhouse product. But, for those who want more power, we offer the Syn-flex® 1500 formula. It contains 1,500 mg. of Glucosamine and White Willow Bark for even greater anti-inflammatory power! But that’s not all... it’s a smooth Mandarin Orange flavor and wonderful!


What is White Willow Bark?


White Willow bark contains an ingredient called Salicin. When introduced into your body, it becomes salicylic acid. In an arthritis product, it provides one more anti-inflammatory to the formula. It also helps reduce prostaglandins which cause pain and inflammation.


White willow bark is not aspirin. Nor, does it have the side effects which can be caused by aspirin.


Using White Willow bark for arthritis pain and inflammation has been shown to be safer, with fewer side effects, than aspirin. Although aspirin was originally derived from acetylsalicylic acid, White Willow bark provides relief without some of the possible side effects of aspirin (if you are allergic to aspirin, talk to your doctor before taking Synflex® 1500 or use Synflex® Original). As those who have used Syn-flex® Original formula know, we have powerful anti-inflammatories working for you. Syn-flex® 1500 just adds this little “extra” power to the formula. Safe, highly effective and delicious!
