Is the product Nopalea effective?

The product you mention is primarily derived from prickly pear, a cactus.
Like many hebal therapies it just depends. It depends on you, your environment and your general health. You do not state what you are trying to treat.

Some pricky pear extracts are produced in china, so who knows what could be contained in those.

this artical from 2003 states:
Capsules containing dried prickly pear cactus are a popular item on both sides of the border and are used to treat diabetes, high cholesterol and obesity (Aguilar,
2001). Although nopal capsules are known to lower serum cholesterol levels both in humans and animals, they may not be efficient in the treatment of diabetes as , theoretically, the active ingredients are possibly lost upon heating and drying or processing (Lozoya, 1999).

I started taking the nopalea in the beginning of July. My feet had been extremely swollen and painful for years. My doctor was in the process of getting me a wheelchair when I saw the infomercial. I thought it was a bunch of crap but I ordered it anyway. A week after I started taking it I realized that my feet no longer hurt. I am a volunteer for the animal projects at our county fair. I was on my feet for 12 hours a day for 7 days. Every night when I got back to the campsite I would poke my feet to make sure they were still there. I hadn't been able to stand for more than a few minutes prior to this. At first I thought maybe it was all in my head but the fact that I didn't actually think it would work convinced me that my body was really better.

It is definately worth trying. If it doesn't work for you just don't order more. I personally think everyone should try it. I never thought anything would make me feel better and I just can't express how pleased I am with this drink.

Good luck
