If you don’t think you’re getting enough vitamin B12, think about getting Jarrow Formulas – Methyl B-12 Vitamins. Why? Because “Vitamin B12 deficiency is associated with infertility,” says hematologist Michael Bennett, M.D. in Could it be B12? “Pregnancy may occur in the presence of B12 deficiency but may be associated with recurrent early fetal loss.”
Plus, a deficiency of B12 leads to reduced sperm counts and sperm motility. To learn more about the effects of this vitamin on fertility rates, read Could It Be B12?: An Epidemic of Misdiagnoses.

Fertility and B12 Vitamins
“Doctors have reported successful pregnancies in once-infertile women following therapy for B12 deficiency,” write Pacholok and Stuart in Could it be B12? “Yet often, sadly, this deficiency is overlooked even by infertility specialists until women have undergone months or even years of unsuccessful treatment. As a result, many couples spend thousands of dollars and suffer disappointment after disappointment, when treatment with B1 injections might have solved their problem.”

These authors say researchers don’t know exactly why a vitamin B12 deficiency makes it difficult to get pregnant and carry the baby to term. The deficiency could interfere with ovulation or normal cell division – and even affect how the fertilized ovum is implanted in the uterine lining.
Whatever the exact link is between vitamin B12 deficiency and female or male infertility, these authors say that a B12 test may improve the chances of getting pregnant naturally. Also — it may be wise to avoid certain foods when you’re trying to conceive a baby.

A New Way to Dectect Vitamin B12 Deficiency
Researchers have developed a new test to detect the levels of vitamin B12 using your breath, allowing for a cheaper, faster, and simpler diagnosis that could help to avoid the potentially fatal symptoms of B12 deficiency. In a study published today, 23 June 2011, in IOP Publishing’s Journal of Breath Research, researchers have developed a simple, non-invasive, low-cost breath test to more accurately measure vitamin B12.
Vitamin B12 deficiency is a growing public health problem in which the most common tests – using blood serum levels – are limited in accuracy and sensitivity and are non-specific for vitamin B12. Vitamin B12 plays a crucial role in the functioning of the brain and nervous system whilst also being essential for the formation of red blood cells; however in low levels it can cause fatigue, clinical depression and memory loss as well as more detrimental and irreversible effects on the brain and nervous system. Several reports have also linked B12 deficiency to pernicious anaemia and Alzheimer’s disease.
Vitamin B12 deficiency can often be asymptomatic, which means you may not know you are deficient. If you don’t know you’re deficient, you won’t know how vitamin B12 affects your fertility. This accentuates the need for a more accurate and reliable test. The initial testing of the B12 breath test conducted measurements on subjects with chronic pancreatitis, Crohn’s disease, and small intestinal bacterial overgrowth, as well as patients over 65 – all of which are associated with a higher incidence of vitamin B12 deficiency. After fasting and not smoking for 8 hours, the study subjects were orally administered 50 mg of propionate and then tested every 10 minutes for the first hour and every 15 minutes for the second hour, with the best diagnostic accuracy appearing to be the 10 and 20 minute intervals.
To ascertain the accuracy of the breath test, the obtained vitamin B12 levels were compared with several blood compounds that are currently used to ascertain vitamin B12 deficiency. The authors concluded that the results from their study indicate that the vitamin B12 breath test is a non-invasive, sensitive, specific, and reproducible diagnostic test to detect vitamin B12 deficiency.
