Methylation also may not address the yeast on the penis. Yeast on sexual organs can be caused by candida in the kidneys and skin problems can be directly related to liver issues (inability to detox toxins so you have to detox via the skin). Addressing methylation is great for overall general health but I think there may be more simpler things that need to be addressed to find relief and results. Examples include addressing the underlying pH, inflammation, digestive problems, dehydration, and how much you chew your food. If your sons digestion is sluggish (1 bm or less per day) than this is the first thing I would try to improve if it was me. You can address methylation all you want, but if you are constipated and not pooping enough, this is possibly a more significant problem.
