Did you know? – Low levels of B12 increase your risk of gastric cancer by 5.8 times?
Low dietary B12 levels are associated with a 56% higher risk of breast cancer!*
A more accurate means to determine your B12 levels is a blood test called methylmalonic acid test and not a serum B12 levels. Elevated methymalonic acids levels indicate a B12 deficiency.
You may be more likely to develop vitamin B12 deficiency if you have:
- Atrophic gastritis, in which your stomach lining has thinned
- Pernicious anemia, which makes it hard for your body to absorb vitamin B12
- Conditions that affect your small intestine, such as Crohn’s disease, celiac disease, bacterial growth, or a parasite
- Immune system disorders, such as Graves’ disease or lupus
- Gene mutation
You can also get vitamin B12 deficiency if you follow a vegan diet (meaning you don’t eat any animal products, including meat, milk, cheese, and eggs) or you are a vegetarian who doesn’t eat enough eggs or dairy products to meet your vitamin B12 needs.
Symptoms of Vitamin B12 Deficiency
If you have vitamin B12 deficiency, you could become anemic. A mild deficiency may cause no symptoms. But if untreated, it may lead to symptoms such as:**
- Weakness, tiredness, or lightheadedness
- Heart palpitations and shortness of breath
- Pale skin
- A smooth tongue
- Constipation, diarrhea, loss of appetite, or gas
- Nerve problems like numbness or tingling, muscle weakness, and problems walking
- Vision loss
- Mental problems like depression, memory loss, or behavioral changes
Look at the different forms of B12 below:
The recommendation for supplementation of B12will depend on an individuations needs, but you diffidently want to avoid cyanocobalamin, unless you are a fan of cyanide, but unfortunately that is the form that is in the majority of multivitamins.
