awesome product.

I take supplements so this one to help with the cells in the body to keep them healthy and strong I've learned as we age our cells don't bounce back as they did when we you were young so this helps me.

Great value

We use this for our dog, it comes in easy to open capsules with powder inside that we can sprinkle on her food. Great value.

Crossing fingers

I bought this after reading an article about its effect on the liver. So far, so good butt it doesn't taste the best. ;)
