Vitamin B12 does a lot of things for your body. It helps make your DNA and your red blood cells and since your body doesn't make vitamin B12, you have to get it from animal-based foods or from supplements. While B12 is stored in the liver for up to five years, you can eventually become deficient is your diet doesn't help maintain the levels.  Getting B12 on a regular basis is essential for your health.

Food Sources of Vitamin B12

You can get vitamin B12 in animal foods, which have it naturally, or from items that have been fortified with it.  Animal sources include dairy products, eggs, fish, meat, and poultry. If you're looking for a food fortified with B12, check the product's Nutrition Facts label.

Why you need B-12 & Vitamin B12 Deficiency

Most people in the U.S. get enough of this nutrient. If you're not sure, you can ask your doctor if you should get a blood test to check your vitamin B12 level. With age, it can become harder to absorb this vitamin. It can also happen if you have had weight loss surgery or another operation that removed part of your stomach, or if you drink heavily.

You may also 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
  • Alcohol misuse or heavy drinking can make it harder for your body to absorb nutrients or prevent you from eating enough calories. One sign that you lack enough B12 may be glossitis, or a swollen, inflamed tongue.
  • Immune system disorders, such as Graves' disease or lupus
  • Been taking certain medications that interfere with the absorption of B12. This includes some heartburn medicines including proton pump inhibitors (PPIs) such as esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec OTC), pantoprazole (Protonix), and rabeprazole (Aciphex), H2 Blockers such as cimetidine (Tagamet) and famotidine (Pepcid AC); and certain diabetes medicines such as metformin (Glucophage).

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. In both of those cases, you can add fortified foods to your diet or take supplements to meet this need.

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

Treatment using B12

If you have pernicious anemia or have trouble absorbing vitamin B12, you'll need shots of this vitamin. Preventive Medicine Centers only use the higher quality methylcobalamin. If you happen to have the MTHFR gene mutation this is the only Vitamin B-12 that you will be able to absorb. We assume everyone has this gene mutation and only use methylcobalamin to ensure you absorb and assimilate your B-12.

B-12 Menu of Options

Since 1997, we have provided life changing services including bio-identical hormone replacement, IV therapy and Vitamin Injections. We only use methylated vitamin B, methylcobalamin vs. the non-methylated version called Cyanocobalamin (cheaper version) which in people with a common gene mutation called MTHFR cannot be absorbed.
