Magnetic Collars

Magnetic therapy has not been scientifically proven yet there are a lot of people who say that it has helped them or helped their pets. Before you purchase any magnetic product please check with your doctor or vet as there are certain conditions where magnets shouldn't be used, for example if someone in the household has a pacemaker it could be affected by a strong magnet.  For more information and a critical review of magnetic therapy there is a very good article on the Medic8 website.  Here's an extract,

"In the studies that did find benefits from magnetic therapy, many have shown those benefits very quickly. This suggest that if a magnet does work, it should not take very long for the user to start noticing the effect. Therefore, people may wish to purchase magnets with a 30-day return policy and return the product if they do not get satisfactory results within 1 to 2 weeks."
