This week's questions:

1. My thyroid reports have been normal every time my doc checks them but I have all the symptoms of thyroid problems is there something I am missing?

2. I am confused about whether I should be taking probiotics or not, no gut issues, advice?

3. What is the best source of protein powder and is NNU (net nitrogen utilization) a valuable guide?

4. I have heard all the talk about methylation and MTHFR, should I just go ahead and take methyl-folate, SAMe, NAC, and methyl-B12 and not worry about getting tested for the MTHFR?
