The relationship between vitamin B12 and fertility is becoming a hot topic in reproductive health. As we well know vitamin B12 supports our bodies functioning at a deep cellular level. 1 What many people are not aware of is the potential of our favorite vitamin in supporting optimal reproductive health.2 We’ll explore research that makes the case that maintaining B12 levels may be essential for the smooth functioning of reproductive organs in both men and women and for being able to carry a baby to term both naturally as well as with assisted reproductive treatment. 3,4,5
Connection Between B12 Deficiency and Gluten Sensitivity?
B12 Deficiency and gluten sensitivity (GS) are generally considered to be unrelated, except in cases of diagnosed celiac disease (CD). Taking a look at new findings on GS and connecting the dots challenges this assumption. Examining the issue in depth leads us to consider the possibility that vitamin b12 deficiency may be a factor for some GS sufferers as well.
B12 and the Holiday Blues…
Research shows vitamin B12 may help depression, and at this time of year it’s a good idea to look at anything that might be putting us off balance. After all, the holidays aren’t so happy for many of us. Add seasonal affective disorder (SAD) into the mix and the seasonal blues can plain just get in the way of enjoying life.
As research is developing so is our understanding of how vitamin B12 can play a role in reducing depressive symptoms. Interesting findings focus specifically on the chemical relationship between vitamin B12 and
An ongoing 18 year long study challenges several commonly accepted truths about B12 deficiency. If you are young and eat meat you likely believe you have a reduced risk of deficiency – maybe not…
Study Found 39% at Risk of B12 Deficiency
Most of us believe if we follow a diet heavy in animal products including meat, eggs or dairy, we should have enough vitamin B12 in our bodies. Researchers at Tuft’s University suggest that this may not be the case. They cite the Framingham Offspring Study which found 39% of subjects were at risk of becoming vitamin B12 deficient.(1) An important detail is the cross generational nature of this study: 26-49, 50-64 and 65-83.
Framingham Offspring directly contradicts the commonly held view being passed down to dinner tables over the generations: that heavy meat eaters are less likely to be clinically deficient than the rest of the population. In fact, participants who had the best vitamin B12 levels were those that ate fortified cereals.
Vitamin Absorption and Resulting Deficiencies are not Necessarily Symptoms of Ageing
Remember when we noted that the Framingham Offspring was cross generational? The study participants most at risk of vitamin B12 deficiency provide insights on the relevance of age to vitamin absorption. Surprisingly, vitamin B12 deficiency is to date no more common among the older portion of the sample. Moreover, this finding challenges the widespread belief that absorption and resulting deficiencies are necessarily a symptom of ageing.
Educating yourself about vitamin B12 deficiency can be hard work. You need to be able to understand your health professionals. Thankfully Tracey, a self described “patient with B12 deficiency,” has collected and organized a huge collection of vitamin B12 deficiency links and information. As always you will want to consume internet research with a critical eye … confirm with your doctor and look for references!
This site was created as a hub to bring all the key websites on vitamin B12 deficiency together in one place.
Once in a while life throws something our way which is completely impossible to ignore. I was diagnosed with vitamin B12 deficiency in 2012 and the profound lack of knowledge of this condition inspired me to join others in raising awareness of this very common but little known life threatening deficiency. Please head straight for the Life Savers page for direct links to support groups and key sites.
Hello, you may have just been diagnosed with B12 deficiency or you may have had this condition for a while. Sometimes our doctors do not tell us all we need to understand, so please use this page as your ‘crash course’ in B12 deficiency.
Getting your daily recommended dose of vitamins isn’t always easy, but this can be especially true when it comes to vitamin b12. Vitamin b12 (also called cobalamin or in it’s different forms cyanocobalamin, methylcobalamin and hydroxocobalamin) plays a key role in the overall function of the brain, nervous system, and even the formation of blood within the body. Even so, many people aren’t getting the daily dosage of this vitamin that the body needs.
Importance of Vitamin b12
Because vitamin b12 plays such a huge role in the nervous system, brain function, and blood production, there are many ways in which a b12 deficiency can impact the body. Specifically, those who aren’t getting enough vitamin b12 often find that they suffer from ongoing symptoms such as:
- tingling in the hands, legs, and feet
- general, unexplained fatigue
- memory loss and other cognitive difficulty
- paranoia and hallucinations
Unfortunately, because many of these symptoms can be attributed to other medical conditions it can be very difficult to diagnose a vitamin b12 deficiency without specifically testing for b12 levels within the body.
Decreased b12 Absorption With Age
Anybody can be vitamin b12 deficient, but it’s more common among the elderly. That’s because, as people age, the body’s natural ability to absorb this vitamin from food decreases significantly. Furthermore, older people tend to eat fewer foods that are rich in vitamin b12 as they age, which only contributes to the problem.
Amanda Shupack has compiled a list of reasons you could have lower energy than you should. The list isn’t exhaustive or in depth, but B12 makes an appearance at #4. I am sure some of our clients are wondering about her research, but it is HuffPost…
It’s sometimes easy to pinpoint why you’re flagging by the afternoon — that weekend of partying, for instance — but sometimes the causes are more complicated.
4. You’re low in vitamin B.
You need B vitamins for your mitochondria to turn glucose into energy. We can absorb B vitamins well in liquid or pill form, but 99 percent of us don’t get enough from our diets. Try taking a vitamin in the morning and evening. This will keep levels stable and get you energized, and there’s no harm in it since you’ll excrete any excess water-soluble vitamins.
If you’re having symptoms of low energy, check your vitamin B12 and D levels, and, in any case, have them checked annually. If you find you have the rare case of not absorbing them well into your intestine and stomach, you can get a B12 injection yearly.

An interesting study conducted in Paris hospitals with 14k participants aged 50-90 years. Vitamin B12 deficiency is found to increase with age – “functional B12 deficiency was 9.6% in patients aged 30-60 years and 14.2% in patients over 90 years”.
BACKGROUND: Cobalamin deficiency is responsible for hematological, neurological, neurocognitive, and neuropsychiatric impairments and is a risk factor for cardiovascular diseases, particularly in the elderly people.
METHODS: In order to determine B12 status in old inpatients, a total number of 14,904 hospitalized patients in whom B12 measurements were performed in five hospitals in the Paris metropolitan area were included from January 1, 2011 to December 31, 2011. The aims of the study were to determine whether age had an impact on B12 and folate deficiencies and to evaluate correlations between B12 and biological parameters-folate, hemoglobin, mean cell volume, homocystein (tHcy)-and age.
RESULTS: Patients were aged 70.3±19.5 years. Low B12 concentration (<200ng/L) was observed in 4.6% of cases, 24.2% had middle B12 concentration (200-350ng/L), 12.6% were functional B12 deficient (B12 < 350 ng/L associated to high tHcy level, tHcy > 17 µmol/L), 20.4% had low folate concentration (folate < 4 µg/L), 10.6% were functional folate deficient (folate < 4 µg/L associated to tHcy > 17 µmol/L), and 4.7% of patients were both functional B12 and folate deficient. … Frequency of functional B12 deficiency was 9.6% in patients aged 30-60 years and 14.2% in patients over 90 years. Frequency of functional folate deficiency was 9.5% in 30-60 years and 12.1% in >90 years.
CONCLUSIONS: In inpatients, functional B12 deficiency and functional folate deficiency increase with age and are not associated with anemia or macrocytosis. False vitamin B deficiencies are frequent.
The last statement of the conclusion is puzzling – wonder if it is central to the study or an interesting aside. Would appreciate any input on that point.
