Mild vitamin B12 deficiency causes exhaustion, which can occasionally be incapacitating. Recently, physicians in the UK identified a lady who had “dangerously low” vitamin B12 levels and had suffered from great weariness and difficulty walking for years.
Dietitians and medical professionals advised Insider that if someone is worried about a vitamin deficit, they should see their healthcare practitioner before beginning supplement use on their own.
The following are 4 vital functions that vitamin B12 fulfills in the body:
1. Red blood cell production requires vitamin B12
The production of red blood cells, which carry oxygen throughout the body, depends heavily on vitamin B12.
The complex process of creating hemoglobin, the protein in red blood cells that delivers oxygen, is aided by vitamin B12. Succinyl CoA, a molecule that the body eventually converts to hemoglobin, is activated by B12.
Cleveland Clinic claims that without B12, the body cannot produce enough hemoglobin to create healthy red blood cells. A vitamin B12 deficiency can cause anemia, which can cause a lack of healthy red blood cells and cause symptoms like pain, difficulty walking, memory loss, mood swings, and vision issues.
2. The vitamin is crucial for the synthesis of DNA.
The National Institutes of Health state that vitamin B12 aids in the catalysis of biological processes that result in the production of DNA and RNA.
People lacking in B12 manufacture DNA slowly, according to the NIH. Because DNA serves as the basis for all cells, those who don’t get enough vitamin B12 may experience megaloblastic anemia, a condition in which the body generates abnormally big red blood cells.
According to the National Organization for Rare Disorders, individuals with megaloblastic anemia may experience a variety of neurological symptoms, such as:
- Tingling or numbness in the hands and feet
- Vision loss
- Balance problems
- Panic attacks
3. B12 keeps nerves healthy and secure.
The B vitamins B12, B1, and B6 are referred to as the “neurotropic” B vitamins because they help to maintain a healthy central and peripheral nervous system, according to the Cognitive Neuroscience Society.
Myelin, a protective coating around the nerves, is made possible by vitamin B12. According to Cleveland Clinic, myelin sheaths allow nerves to transmit electrical impulses to other nerves quickly and effectively.
According to CNS, the nutrient is crucial for both the development of new nerves and the recovery of damaged nerves. A “tremendous health problem” caused by a B12 deficiency can include cognitive impairment, damage to the nerves outside the brain, and spinal cord breakdown.
4. Weakened bones may result from inadequate vitamin B12 intake.
Osteoporosis, or the thinning of bones, has been related to low vitamin B12 levels. A 2015 analysis discovered that a B12 deficiency may cause the body to produce “osteoclasts,” or bone-crushing cells.
But too much B12 can also be detrimental to your bones. In a study of 75,000 post-menopausal women, it was shown that those who consumed B12 supplements in amounts well over the daily recommended dosage were at an elevated risk for hip fracture.
