It's shocking that millions of pregnant women are advised to take folic acid, which is synthetic vitamin B9. Research shows it can cause cancer!
Be particularly careful with folic acid here - it can cause cancer as it's synthetic - for more on this, search under the words
"folic acid" + cancer
you really need folate, the natural version of vitamin B9.
In 2009, a study by Norwegian researchers published in JAMA showed increased incidence of lung cancers among those supplementing with folic acid. Other evidence has also suggested prostate and lung cancer incidence might be increased.
The proper, active form is folate (vitamin B9). Also, many people cannot convert folic acid supplements to folate, so make sure to buy only folate supplements.
As Dr Mark Hyman warns: "Man-made molecules do funny, unpredictable things because they don't work with our normal biochemical pathways. Nature made molecules we have consumed for millennia work with our bodies. Folic acid, the molecule that is used to fortify our food supply, is used in most studies and in most vitamins. It is a man-made, funny looking molecule - a fully oxidized, synthetic chemical compound that seems to cause [more] mischief [than good]. It costs less and is more stable than the nature-made form of this nutrient.
"On the other hand, the nature-made form or forms, called "folates," do not seem to cause problems. This molecule is often found in foliage - dark green leafy vegetables, hence the name folate. This can enter your normal biochemical pathways and gets properly metabolized. The folic acid may not be converted or metabolized by the body, increasing cancer and disease risk. The excess folic acid becomes oxidized and promotes free radical production and genetic instability leading to cancer and other disease.
"The nature-made form of this nutrient - called methyl folate (and there are a few forms of that too) - is what should be in food and vitamin supplements. Many conscientious companies are now using only this form of the nutrient, but it is more expensive. Look at your supplement label: if it says "folic acid" then find another vitamin that has the words "L 5 methyl-tetrahydrofolate" or "5 formyl tetrahydrofolate" on the label."
