Good thing if you were doing vitamins on the cleanse that you stoped them cause you certainly would not be doing yourself any favors. One you'd pee most if not all of them out and since the main working of the MC is to give the digestive system a rest it working at odds to this principle because the body would have to spend energy otherwise used for cleansing and healing to digestg and process the solid vitamins. The other minus is that sisnce digestion woulda remained active it is highly likely that you would remain hungry thoughout the fast.

While the MC is a good overall cleanse it is not considered a colon clenase so don't guide yourself by the butt pee. Do your colonics post MC regardless.

While there are the juicers that are considered the better ones the best juicer  still comes down to the best one is the one you have and will use. So crank that baby up and juice them veggies.

My favorite and pretty much my daily staple veggie juice is as follows.

 2 lbs of carrots

2-3 good sized stalks of celery

1/3 to 1/2 red beet depending on size

Parsley and Cilantro. A bunch each where the stems amount to the cirmuference of one finger

 2 green apples

Thumb size chunk of ginger

My other regular juice is to cut back on the content of the carrots and beets is

2 Cucumbers

2-3 stalks of celery

some of your fave leafy greens (kale,spinach, romain etc) aqnd/or parsley and cilantro

2 Apples

Chunk of Ginger

Greens can be pretty bitter when juices so I use the apples and ginger to mellow it out
besides them also being having excellent nutritional content and the ginger is also good for digestion
