I included a bit of reading material from HyperBiotics for you to read!
I learned that 60% of the beneficial flora in their products will survive the stomach acid's of a child, and get to the intestine where they are truly needed. Some key points about the probiotic of theirs is that :1) it helps repair your child's microbiome, 2)they reverse the cycle of antibiotics, 3)full nutrient absorption, and 4) it reactivates their natural defenses. That's impressive to me! I would definitely recommend these during any season of the year! If you don't give them to your children for gut heath, at least get them taking them when they are antibiotics!
