I wouldn't use juice at all, any juice.
Not good for liver and metabolism period.
If you believe in pomegranate, and want to try it anyways, I'd recommend to at least put it in the blender together with some high fiber fruits/foods.
But again the fructose alone isn't ideal from a health standpoint.
Stick to the basics:
basic multi
fish oil
protein from lean meats and fish
fats from nuts and olive oil (uncooked)
carbs from rice, oats, potatoes, sweet potatoes
as many vegetables as you want
zero to low caloric hot sauces and dips like mustard, tabasco, chilli, etc...
celtic sea salt
Done...
