It takes over 14 grams of fresh ginger root to produce the amount of concentrated extract found in each of these capsules! Each capsule provides 24mg of gingerols, which are volatile compounds that are easily lost if ginger is cooked, dried or crystallised. Very few supplements provide this level of gingerols, and in fact many do not even declare a level on the label.
The dark rich concentrated ginger paste is dissolved into sunflower oil and supplied in capsules. Using this method ensures that the active constituents such as the gingerols and zingerone are preserved.
Ginger has a long history of use particularly as an aid to digestion since its 'warming' properties means it has a settling effect on the system. More recently ginger supplements have been recommended as part of joint care programs, alongside products such as glucosamine and fish oil.
