Grapefruit Juice vs. Lemon Juice

Is there an advantage to taking Grapefruit Juice over Lemon Juice? I would prefer to stick to lemon as part of my candida diet, but if Liver Flush results are significantly better with Grapefruit Juice than with Lemon Juice, I would definitely be willing to go with the Grapefruit.

Thanks for your advice!
