Benefits of Vitamin B12

As we wade-through the winter months, many people get tired and bogged down. Energy and mood can be low, and stress levels can become more difficult to manage. Vitamin B12 injections are something that I love to use to help my patients (and myself!) cope with stress, low energy, and a whole host of other concerns.

What is Vitamin B12?

Vitamin B12 is a nutrient called cobalamin that your body cannot produce on its own. Typically we get B12 from foods; the richest sources being clams, mussels, salmon, beef and eggs. Vitamin B12 is necessary for many crucial functions in our bodies. It is used to convert food to energy, make red blood cells to carry oxygen around our bodies, make DNA and nerve cells, balance hormones, detoxify, and fight infection. It’s amazing to think that this little nutrient is so important, and yet many of us are deficient.

Who benefits from B12 injections?

B12 deficiency causes fatigue, depression, mood swings, poor circulation, poor memory, brain fog, muscle weakness, and/or tingling in the fingers and toes. People with a B12 deficiency often have difficulty coping with stress, have low energy, and have symptoms of excess estrogen. Most people with these symptoms can benefit from B12 injections, and it’s not toxic at moderately high levels.

Vitamin B12 deficiency is very common, especially in people under stress, people over 50 years of age, and vegetarians or vegans. We often don’t get enough B12 from our diet, so B12 injections provide a boost of B12 into the body, and then in most cases you can take a supplement to keep your levels high.

Some people have a condition called pernicious anemia. These people produce less intrinsic factor, which is needed in the stomach to absorb B12. Moreover, if you are over 50, or taking proton pump inhibitors or antacids, you are also likely not absorbing B12. For these people, B12 injections are necessary to ensure your body is getting enough of this essential nutrient.

Energy Production and Stress Management

Vitamin B12 is an essential for converting food into energy, or ATP, and without it the process slows down dramatically. People who feel sluggish, or low in energy even with adequate sleep and a good diet, would likely benefit from B12 injections. The injection gets that pathway working efficiently and gives you a boost of energy.

Stress takes both an emotional and a physical toll on our bodies. Vitamin B12 helps us to cope with stress by balancing our brain chemistry, sharpening our cognitive abilities, and improving our memory. It also reduces physical stress in the liver by methylating and detoxifying hormones and toxins.

Brain Function – Depression and Alzheimer’s disease

Vitamin B12 is necessary for the production of monoamine transmitters, which are deficient in people suffering from depression. Research shows that B12 injections improve mood in some depressed patients without the use of antidepressants.

Symptoms of B12 deficiency such as memory loss and reduced mental state are also found in dementia. There is growing evidence that many people diagnosed with Alzheimer’s and dementia are actually overlooked cases of B12 deficiency. Studies show that the progression of Alzheimer’s can be prevented if treated early with B12.

Infertility and Hormone Health

B12 deficiency is also often overlooked in cases of infertility and irregular hormone patterns. Vitamin B12 it is used to break down estrogen so that it can be excreted from the body. As a result, women with B12 deficiency may experience infertility or irregular cycles because high estrogen levels can cause lack of ovulation, embryo implantation failure, and difficulty maintaining pregnancy. Low B12 can also cause hypercoagulability, which is a cause of early recurrent miscarriage.

Testing and Treatment

I recommend annual B12 testing every 6-12 months, with regular monitoring of your levels if you are receiving B12 injections to improve your mood, memory, energy, immune system or balance hormones.

If you and your ND decide that vitamin B12 injections would be beneficial for you, we are pleased to provide B12 injections at our clinic. Please contact our office for more information.
