In brief: Elevated blood sugar

Aside from that, which pre-diabetics and diabetics need be aware.
Virtually none. A cochrane analysis (medical think tank) found no conclusive benefits from this or chondroitin sulfate. I am the side that does not think it works. Last year $3.8 billios dollars were spent on this product alone. Check the label: fda does not endorse this product for treatment of any disease!

In brief: Mild side effects

Glucosamine is an amino sugar that is often taken as a nutritional supplement for arthritis.
In several large clinical trials the side effects were mild and infrequent consisting of constipation, stomach ache, rash and hives. Since glucosamine is often made from the shells of crustaceans there is a theoretical risk of an allergic reaction for those with seafood allergies, but is rarely seen.
