Jointace? Magnets utilise special high grade ceramic magnets for high magnetic permeability and a strong active field. These special bio-magnets emit a safe magnetic field that penetrates to where it is most needed. Static magnetic fields may provide sustained support for joints and muscles. Jointace? Magnets provide a complementary approach. The magnets are free from side effects and are ideal used alongside Jointace? Glucosamine and Chondroitin supplements. Jointace Magnets can be used for as long as required, and are suitable for long term use. Jointace?
