@ MicroMan.... I am ever waiting to see you post links to
valid studies showing your point of view.

The people who tend to end up on NT IMO, as I have been here since 2006, are those who are not healing well, who have been overlooked by numerous doctors who do not check for low B12, accept the horrid side effects from several drug families, (acid blocking drugs, fluoroquininolones, statins) and need interventions of certain nutrients, and have other masked and/or unidentified chronic issues.

Many of them find that replacing certain nutrients (not just taking a daily multivitamin), helps them considerably. The MS forum is one that uses certain things to treat MS...vitamin D, and a few other things. Our PN forum, has several nutrients that help with nerve pain, and we also recommend lowering sugar and white carbs in the diet, and avoidance of foods that may have histamine consequences.

What we discuss here on NT is not the same as Yahoo news items, or other typical internet self help dietary advice.
What I have seen HERE are people suffering from MTHFR mutations who doctors don't even know what that is! People going to 5, 10, yes and even more doctors, who never have tested them for B12 levels.

Here is one example of what is going on in medical offices in this country:

So I would like to see some links from you. No hurry...
And I'd like to reiterate, that I have not seen anyone on NT suggesting all adults in the US need to take a daily multivitamin. The people who come here are damaged, and need healing help. Check out Dr. Blaylock MD's website. He was recommending certain nutrients to his neurology patients long before this board, or the complementary medical movement. He is now retired but was a neurosurgeon for many years. He follows the research closely and offers a newsletter for a small fee to share his current opinions and insights.
