Just trying to push this back up so i can get more answers. Thanks to all that have replied. The Ultra Mega sounds like the best from what i have learned i like gold because it does not have iron and i dont think i need any more iron since i am eating a ton of red meat. and the Green has fibre which the gold doesnt list so i am still looking for the best of both worlds. I may go with the Gold and then take another fibre supplement
