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."

Holy dreams Batman!
Flavor Name: Peppermint
This product is so good I had to come back to review it! I originally got this for my daughter since she has terrible insomnia, but she hated the minty taste...so I started taking them along with my husband and wow is all I have to say! It makes me tired and I’ve been having the craziest dreams (I usually never dream or remember them)! Definitely recommend and I actually really like the flavor.

Not fast dissolve. After 20 minutes, it still sits beneath my tongue.
Flavor Name: Peppermint
This is definitely not fast dissolving tablets. My B12 and biotin sublingual tablets dissolve in a couple of minutes but these pills last over 20 minutes.

Good supplement for uric acid support
My dad has been using this support supplement for uric acid for a while and I thought it was a good option. The ingredients feel of quality and are easy to take, as the capsules are of adequate size and do not cause stomach discomfort. I like that it is also focused on kidney support and that it does not have a strong taste or noticeable side effects in my case. It is a convenient alternative to complement a balanced diet and healthy habits. The value for money is good and the packaging performs a lot. In general, I am satisfied with the product and would buy it again.
