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."

Buying another package
Size: Large, Color: Multicoloured D (5-pack)
Oh my gosh, I love these!!! They are very comfortable and not overly tight. The material is so thin and breathable, very comfortable. Love the colors. Am buying another package! I'm in perimenopause and these definitely keep me cooler than my tradition cotton underwear.

Soft and comfy
Size: XX-Large, Color: Black
Nice, soft, fits pretty well although space between cups is a little oddly wide which I’ve never had an issue with before. Still, it’s cotton and comfortable.
