Early miscarriage is linked to VITAMIN B12 deficiency

by Ivy Eff

Recommended dosage: 400-1000 mcg twice a day. Take in combination with folic acid or (preferably) folate 

In one study, a group of women who had had multiple miscarriages and no full term pregnancies were supplemented with Vitamin B12. Two months later, they were allowed to try to get pregnant. A significant number of these women then went on to become pregnant and carry to term.

The conclusion of another study was that “Vitamin B12 deficiency is one of the causes of recurrent pregnancy loss.

Yet another study (unrelated to fertility but about B12 in general) found that 39% of Americans may suffer from “low normal” levels of Vitamin B12. That is, the level falls below 258 pmol/L. Even though this level is considered to be well above the deficiency level (148 p,ol./L.), even at a low normal level, people often show symptoms of deficiency, like confusion or problems with balance. It could be extrapolated that if other deficiency symptoms show up a “low normal” levels, fertility could be affected, too.

Get checked specifically for your B12 level.

Some doctors make assumptions regarding B12 levels based on elevated levels of homocysteine and methylmalonic acid instead of testing the actual B12 level. But half of all women with low B12 actually have normal levels of homocysteine and methylmalonic acid. So request that your doctor test you. Keep in mind, too, however, that high levels of folic acid can hide a B12 deficiency.

Vitamin B12 is difficult to get solely from your diet.

It is notoriously hard to absorb Vitamin B12. First, it is only available from animal products. Second, it is very tightly bound to the animal products so it requires a lot of acid to break it off and make it usable. However, some people have naturally lower stomach acid. For others, their stomach acid levels reduce as they get older. Without high levels of stomach acid, your body may be unable to separate and use the Vitamin B12 found in your foods.

Your body may also be unable to use some supplements of B12.

Even with supplementation, many people have difficulty obtaining Vitamin B12. That’s because B12 usually found in the form of cyanocobalamin. Unfortunately, in order for the body to use cyanocobalamin, certain enzymes in the body need to convert it first. But common defects in enzymes — as well as dietary deficiencies, or abnormal tissues  — can make you unable to convert and use that form of B12 at all. In that case, no matter how much B12 you think you are supplementing with, if it’s in the wrong form for you, your body may still be quite starved of it.

Another form of B12 is known as methylcobalimin. This form DOES NOT need to be converted first, so it is ready to be used by the body immediately. For those with the common MTHFR gene defect (which may be as many as 50% of the population and across multiple ethnicities), high levels of homocysteine, or neurological problems, this form can be especially effective.
