All that wiggles may not be Jell-O, but it may be medicine for your joints. Gelatin has been found by many to be helpful in decreasing the symptoms of arthritis, increasing mobility and decreasing pain and stiffness. Plain gelatin is most commonly sold in small envelopes as Knox Gelatine, but Knox also sells this product in larger containers as Nutra Joint. This form is intended to be used in hot or cold beverages daily in a 10-gram dose.
The plain gelatin can also be mixed in hot beverages quite easily. One packet is the usual dose. So why would gelatin have anything to do with the joints? As it turns out, gelatin is very similar in structure as the collagen type 2 that makes up the connective tissues of the body including cartilage. Cartilage is like Teflon, a slippery surface to allow joints to easily slide against each other.
In arthritis, the cartilage becomes roughened and less slippery which causes restricted movement. The theory with using gelatin for arthritis is that this precursor to cartilage helps the body to repair damage and also keeps damage from occurring in the first place.
