This is propaganda! 2.9% ?.... at least that is less than the infamous Vit E story that came out a few years ago.

The last part of that story, reveals the intent of the article...
It is about CONTROL and government regulation. The new bill coming perhaps, is the target.

How studies are run, is very important. The drug companies know this and massage their data using mathematical tricks to make their drugs look better than they really are. They choose subjects with very poor placebo responses, (high placebo responses are common), and also pick subjects likely to respond favorably. They hide damaging data. The ADHD studies using stimulants and strong drugs in children are examples. One doctor formerly from CHADD, made public how he was censored by a drug company for telling the truth in one study. It was quite a scandal at the time. Scandals have been reported around Zyprexa (one doctor shredded his data on test subjects who DIED during early studies) and Luvox doctor was discovered after the fact to have falsified his data too. Oh and let's not forget the doctor in Calif who falsified all the data on Pfizer drug Celebrex for post operative pain....and recently the doctor employed by CDC in the Netherlands who falsified all the vaccine data (claiming no harm) to children who developed autism.
Drugs (approved by the FDA BTW) in this country are the 4th leading cause of death --errors and misuse.

So it is not surprising that "studies" don't move as many as they once did!

There are many people eating a "healthy diet" or so they think...who may have malabsorption in the intestine, or genetic errors preventing use of some vitamins due to poor conversion: called MTHFR polymorphism. There are several drugs commonly used today (most OTC now) that CAUSE malasorption of B12-- all the acid blockers! Do we ignore that? Also if people follow medical advice about sun exposure which appears EVERYWHERE now, they will have no Vit D to speak of! Supplements are the only way to get it these days!
