Clinical studies show that supplementing with glucosamine sulfate may stimulate joint repair. FlexAble Glucosamine Sulfate is fully reacted and is made up of a combination of glucose, glutamine and sulphur. It is generally believed that the sulphur component makes it more useful for joint problems.

This formula is sodium free, for those who wish to reduce their sodium intake or people with hypertension.

One common question: Can persons allergic to sulfa drugs or sulfite take glucosamine? Michael Murray, ND responds: "When people say they are allergic to sulphur, what they really mean is they are allergic to the so-called sulfa drugs or sulfite-containing food additives. It is impossible to be allergic to sulphur because sulphur is an essential mineral. The sulfate form of sulphur is present in relatively high concentrations in human blood. In short, glucosamine sulfate is extremely well-tolerated, and no allergic reactions have been reported."

Nice, sturdy trail running and walking shoes
Size: 9.5, Color: Midnight/Grey Blue
I like Asics athletic shoes. They consistently fit my feet quite well. These shoes seem sturdy and have good grippy tread, ideal for light hiking, trail running and general every day use. Comfortable. My only gripe about Asics is the tread on previous shoes seems to wear out quickly. I walk and hike about 35-40 miles a week and the past Asics I’ve had usually lose their rear tread after six months so maybe that is normal.

Very comfortable
Size: 9.5, Color: Black/Cool Grey
Awesome shoe, very comfortable. As a trail shoe it is a little firmer than a running sneaker as expected. The unexpected was the comfort the shoe provided. Nice looking as well. I've been wearing against most of my life. Always find myself coming back to them when I tried other brands. Size consistency has always been near perfect.

Excellent support and comfort.
Size: 12, Color: Black/Carrier Grey
A comfortable, lightweight shoe, with a nice heal cushion that gives slightly but not mushy or squishy. Very breathable. A solid choice for everyday sidewalks and trails.
