Hello again #91053,
I suppose you could replenish your intestinal flora with probiotics post-fast, specifically with a probiotics product, but fruit and vegetables and their juices are jam-packed with enzymes that really don't any assistance from the first product mentioned.
Fasting throughout the ages and especially since the advent of Natural Hygiene in the mid 1800's have seen no need to be concerned with the specific replenishment of the intestinal flora as fruit/vegetables do the job more than adequately.
