Quick Facts on Vitamin B12- The Energy Vitamin!

Monday, November 18th, 2013

 

 

Vitamin B12 is one of the most important nutrients for the body- and the hardest to digest, for many people. A water-based B vitamin, cobalamin is essential for the nervous system, blood cells, and for DNA. Yet an increasing number of people don’t get enough vitamin B12 from food, and as a result feel fatigued and disoriented from pernicious anemia.

Quick Facts on Vitamin B12- The Energy Vitamin!

What does vitamin B12 do?

Vitamin B12 is essential for survival; it is involved in some of the most vital processes that take place in the body.

Vitamin B12 helps to maintain production of healthy red blood cells. Without enough vitamin B12 in your system, your body starts producing overlarge irregular-shaped blood cells that cannot function properly, resulting in a depletion of oxygen-carrying hemoglobin.

Vitamin B12 also aids in converting carbohydrates into necessary energy, ensuring that you have plenty of stamina and mental focus during the day.

Vitamin B12 enhances your nervous system functioning by helping to maintain myelin, a fatty coating that surrounds each individual nerve cell.

Vitamin B12 supports cell reproduction and renewal in preventing common signs of aging.

What foods provide vitamin B12?

Foods that are high in vitamin B12 include meats, seafood, poultry, dairy, and eggs. Among these, organ meat and shellfish provide the richest natural source of vitamin B12.

While it’s possible to find vegan products that are fortified with vitamins such as B12, these are not natural forms of the vitamin, and don’t provide the maximum amount needed to maintain healthy vitamin B12 levels.

To prevent deficiency, vegans and vegetarians are recommended to take vitamin B12 supplements on a regular basis.

What about Vegan Vitamin B12?

Vitamin B12 is complicated

Vitamin B12 is one of the few nutrients that require a cofactor for proper absorption. It’s not a simple matter of eating plenty of foods the contain vitamin B12, such as beef, chicken, seafood, and dairy products. To complete the digestion process, your body uses a digestive enzyme called intrinsic factor, which bonds to the vitamin and escorts it through your digestive system.

Vitamin B12 deficiency is anemia

If your vitamin B12 levels have been low for a very long period of time, you may have pernicious anemia, a type of megaloblastic anemia that occurs when people are unable to produce intrinsic factor.

Pernicious anemia can result from an autoimmune disorder or it can occur as a result of damage to the stomach lining (gastritis).

If you have pernicious anemia, then you can’t get enough vitamin B12 from swallowing pills or other dietary supplements. Only supplementation with a highly-absorbable form of vitamin B12 that enters directly into the blood stream can reverse the symptoms of severe vitamin B12 deficiency.

Risk factors for pernicious anemia include:

  • Gastric bypass surgery
  • Removal of ilium for Crohn’s disease
  • Metformin for diabetes
  • Protein pump inhibitors (PPI’s) for GERD, acid reflux, chronic heartburn, or ulcer
  • Family history for autoimmune disorders
  • Chronic migraines
  • Old age
  • Alcoholism

I Eat Healthy…So How did I Get Vitamin B12 Deficiency?

Signs of vitamin B12 deficiency

By the time you start to notice the signs of vitamin B12 deficiency, you are already on a dangerous decline, as it takes years for the symptoms to manifest themselves. Also, blood tests for vitamin B12 deficiency don’t give you ample warning to up your vitamin B12 intake, as they only test for extremely low levels of vitamin B12, and aren’t always even accurate in such screenings.

Vitamin B12 Deficiency- How Long does it Take?

Symptoms that indicate vitamin B12 deficiency include:

  • Constant fatigue, even after sleeping well
  • Depression
  • Slow talking and thinking
  • Brain fog
  • Anxiety
  • Painful numbness and tingling in the hands and feet
  • Muscle spasms, eye twitches
  • Difficulty walking in a straight line
  • Sore, burning red tongue

How much B12 do I need?

The recommended daily allowance for vitamin B12 consumption for healthy people who don’t have a deficiency is a scant 2 or 3 micrograms per day. Why then do most vitamin B12 supplements contain a whopping 1,000mcg of vitamin B12 in one weekly dose?

If you are unable to produce intrinsic factor, then you can only digest about 1% of all the vitamin B12 you get from foods, pills, or other supplements.

So, to get the amount you need to keep your B12 levels at a normal rate, you need to take about 100 times the amount any other person would need to stay healthy.

Does Vitamin B12 Really Promote Weight Loss?

Wednesday, November 6th, 2013

 

 

If you’re considering taking vitamin B12 supplements as part of your weight loss regimen, then you’re off to a good start. Vitamin B12 (cobalamin) helps your body break down fatty acids and amino acids in boosting energy, while it also aids in digestion. Listed are some other ways that taking vitamin B12 shots or over-the-counter supplements can help you manage your weight and stick to a healthy diet.

Does Vitamin B12 Really Promote Weight Loss?

Vitamin B12 supports many important functions throughout your body, including healthy metabolism of fat and carbohydrates.

So, it’s not surprising that many bodybuilders and fitness enthusiasts like to use mega doses of vitamin B12 to increase energy and sustain good muscle development.

Benefits of B12 on weight loss

Here are some excellent reasons to include vitamin B12 supplementation as part of your weight loss plan:

Energy!

Vitamin B12 helps your body produce plenty of healthy red blood cells which are needed to deliver oxygen to your brain, heart, digestive system, endocrine glands…everywhere. Lack of oxygen makes you feel fatigued and dizzy- which makes it difficult to keep your energy levels up while exercising.

By keeping the flow of oxygen elevated, vitamin B12 helps to enhance stamina, mental focus, and good balance- things you need to stay in the game!

Metabolism!

Vitamin B12 aids in DNA synthesis and normal metabolic functioning- this is especially helpful if you’re trying to lose weight, but have a sluggishly slow metabolism.

Vitamin B12 helps to keep the metabolic juices flowing!

Mood!

Sometimes, depression and anxiety make it harder for you to stick to a weight loss program. Research shows that maintaining healthy levels of vitamin B12 in your blood supply is one of the best ways to prevent psychological and cognitive problems that often occur with vitamin B12 deficiency.

To prevent binging on your diet, emotional eating, or other food-related disorders, it’s important to keep your mood in check by maintaining healthy vitamin B12 levels.

How much vitamin B12 is best?

To improve your efforts at weight loss, or just to maintain normal vitamin B12 levels and promote good health, experts recommend taking 1,000mcg of vitamin B12 weekly, bi-weekly, or as often as needed.

There is no upper limit established by the FDA for vitamin B12 supplementation, so it’s safe to take vitamin B12 as often as you like, with no risk for overdosing.

The best forms of vitamin B12 are those that are absorbed directly into your blood stream- vitamin B12 shots are popular, and most often recommended for people with severe vitamin B12 deficiency.

For maximum benefit, you can combine vitamin B12 injections with OTC vitamin B12 supplements. For people who have difficulty getting enough vitamin B12 from their health insurance providers, this is an especially helpful tactic.

How much B12 is in my blood right now?

By performing a blood test, your doctor can tell you if you are deficient in vitamin B12, or if you have normal B12 levels.  Vitamin B12 blood screening requires a 6-8 hour fast before testing.  Laboratory tests will measure how many picograms (pg) of cobalamin you have per milliliter (ml) of blood in your body.

How much B12 should I have?

  • Scientists agree that a normal level of vitamin B12 in your blood is 200 – 900 picograms per milliliter (200-900 pg/ml).
  • Test results showing less than 200 pg/ml signal vitamin B12 deficiency.
  • For elderly adults, the recommended vitamin B12 level is much higher- Test results showing less than 500 pg/ml indicates B12 deficiency.
  • In order to find the cause of a vitamin B12 deficiency, doctors may perform a Schilling test.

What is the recommended dose of vitamin B12?

  • The FDA’s RDA of vitamin B12 for healthy adults is approximately three mcg daily for males and females alike, including pregnant and nursing moms.
  • For elderly individuals, the recommended dose of vitamin B12 is 25-100 mcg per day.

Scientific study proves that the RDA for B12 is off.

  • According to a study conducted in the Netherlands, elderly sufferers of vitamin B12 deficiency need more than the recommended daily allowance (RDA) in order to achieve normal levels of B12.
  • Using methylmalonic acid (MMA) levels as a gauge, scientists established that cyanocobalamin supplementation amounting to 200 times the RDA of vitamin B12 is required in order to stabilize B12 levels in patients showing signs of vitamin B12 deficiency.
