I'm not going to make any claims about my magnetic jewelry, other than the fact that it has certainly helped my arthritis. And it's better made than most of the others you will find.
Necklaces - $30
Anklets - $20
The Necklace Efficiency Test:
Clasp your hands in front of you, palms up and hold them about six inches in front of your body. Have someone push as hard as they can on your clasped hands. You will lose your balance and step forward. Put a magnetic necklace on and repeat the whole operation. If the necklace is a good one, you will be very hard to pull forward, if at all.
This test was told to me by an old fellow who sold really good magnetic jewelry and I couldn't believe what a difference it made! I've got a lot of upper body strength and it doesn't matter when someone pushes on your hands like that. You'll step forward. But with a necklace on, I was like a rock - didn't move!
