Vitamin B12 – Facts You Must Know


Vitamin B12 plays a vital role because it aids the production of DNA and helps make new neurotransmitters in the brain. According to the experts, there’s an increase in Vitamin B12 deficiency, because more people are going vegan and undergoing weight-loss surgery. B12 is commonly found in animal sources, so if you have a deficiency, you should consume more meat, poultry, fish and milk products. If you’re vegan, you should consume nondairy milk, meat substitutes and breakfast cereals to help increase your intake.

7 Warning Signs of Vitamin B12 Deficiency

  1. Dizziness

We can easily say that one of the first warning signs of vitamin B12 deficiency is dizziness. If you experience this symptom, you should see your doctor immediately.

  1. Forgetfulness

Can I ask you something – do you often have a hard time remembering ordinary things like where have you put your keys, or what’s the name of your friend? If YES, then you should know that this doesn’t have to mean that you suffer from early dementia. It also indicates that you suffer from Vitamin B1 deficiency. Many older people think they have Alzheimer’s or dementia, but they actually have vitamin B12 deficiency. You can check this by doing a simple blood test and improve your memory with a supplemental regimen.

  1. Muscle Weakness

If your muscles are weak, they are probably deprived of the proper amount of oxygen from erythrocytes. According to the experts, improper oxygenation to muscle cells and vitamin B12 deficiency can cause uncharacteristic muscle weakness and sluggishness.

  1. Pale Skin

Pale skin might be caused by lack of vitamin B12 which means lack of erythrocytes. How this works – well, your body produces more bilirubin which replaces that rosy complexion with a pale visage.

  1. Pins and Needles

Low amounts of Vitamin B12 can cause paraesthesia – more known as pins and needles. You’ll experience tingling, prickling, or numbing sensation throughout the body, especially in the hands and feet, and a feeling of electric shock waves because of the nerve damage caused by lack of vitamin B12.

  1. Unexplained Fatigue

You sleep good and you’re still feeling tired?! Well, this can be another sign of vitamin B12 deficiency. This unexplained fatigue can occur because of reduced production of erythrocytes in your body which results in insufficient amounts of oxygen been transported to your organs.

  1. Eye Problems

Ladies and gentlemen, you’ll be shocked when we tell you that long-term vitamin B12 deficiency can damage your vision and cause vision changes. The experts warn that lack of this vitamin can cause an optic neuropathy by damaging the optic nerve resulting in reduced central vision, blurred or doubled vision, light sensitivity, shadows or tracers.

Health Benefits of Vitamin B12

  1. Prevents Heart Disease and Stroke

Did you know that heart disease is the leading cause of death in the U.S.?! The answer is YES, and this means that you should take some extra measures to protect your heart. A recent study has revealed that high levels of homocysteine will increase the risk of heart disease. This non-protein α-amino acid can create inflammation if there’s a lack of vitamin B12.

  1. Prevents Nerve Damage

Nerves have a natural covering called myelin sheath and its primary function is to protect them from toxins and free radical damage. The experts warn that without this protective covering, nerves can be easily damaged and killed which can result in nerve-related disorders. This is because dead nerves are interrupting the transmission of signals to and from the brain.

  1. Supports Energy

Here’s what you need to know – Vitamin B12 stimulates the production of energy by keeping your cells happy, healthy, and well-fed. Insufficient amounts of this vitamin starve your cells, making you tired and weak. The metabolism requires vitamin B12 to convert carbs into usable glucose – an essential participant in the production of energy.

  1. Helps Digestion

Vitamin B12 aids in the production of digestive enzymes, which helps the breakdown of foods in the stomach and supporting a healthy metabolism. It helps foster healthy gut bacteria and removes the harmful bacteria in the digestive tract.

  1. Helps Produce Erythrocytes and Prevent Anemia

Since this vitamin helps the production of erythrocytes, it can prevent megaloblastic anemia which is manifested by weakness and chronic fatigue.

  1. Good for Bones

As we said, vitamin b12 can reduce the levels of homocysteine and improve the health of your bones.
