The most difficult part of my job is trying to answer the many questions I receive from customers. The technical aspect of the answer is not difficult, it's the determination of whether the answer is valid for that particular person. Medicine now understands that medical treatment is not a "one size fits all" situation. Personalized medicine will be the practice of the future as we learn more about the human genome and how drugs affect people based on difference in their genetic makeup.
The same is true with dietary supplements. Omega-3s, enzymes, vitamins, probiotics, and botanicals will have different effects on different people. Why does one vitamin/supplement protocol produce wondrous results in one person yet does nothing for another?
The difficulty in answering customer questions lies in that I know they want concrete and defined answers to a problem. But I am hampered in that I only see words in an email and I cannot perform an exam of any kind nor should I give medical information (I'm a PhD, not an MD). I can tell you the science behind a certain product and how it works, but that is no guarantee that it will produce the desired results in you. So many variables come into play: diet, environment, genetics, gut bacteria, and age all factor into how a particular individual responds to drugs, foods, and dietary supplements.
I try to stress that what works for one individual may not happen for another and no one knows the outcome as a certainty. You should not be discouraged if a particular protocol does not produce desired results. Rather, it is a checkmark on your list of things to try. Listen to what others have tried, ask questions, and be skeptical. Skepticism will allow you to more objectively evaluate the results of any protocol, drug, or supplement.
My role in answering your question is to promote your understanding of the known science. I am uncomfortable extrapolating known science to limits beyond validity. This means I may tell you that I don't know if "xxxx" will help you or your child. It may or may not. To tell you otherwise would be deceptive.
My advice always boils down to this: If it is safe to use, try it. Experiment with dose amounts and frequency if you are not sure as to the results. Keep a journal and write down everything. Watch for patterns that may lead you to answers.
