I tried these pills for 6 m0onths with no noticable effect. Certainly not worth the money.
I had better luck with an eggplant tincture you can find out about here. Cut 1 eggplant into 1" chunks and put into a pitcher of water. Let it soak a couple of days and I dring about 4 oz per day. Also, Celery seems to help, supposedly has a lot of magnexium. Eat 2-4 stalks a day. I think I'll try the magnesium tea someone else advised.
