Frequently Asked Questions
Catharine suffered from chronic fatigue, low energy, and difficulty walking, often relying on a mobility scooter. After consulting a new doctor who diagnosed her with a vitamin deficiency, restoring her levels of this vitamin resulted in the disappearance of her malaise and improved her ability to walk.1
This particular vitamin deficiency is more prevalent than many medical professionals realize and can mimic various health issues. Here's what you should understand...
Recent studies indicate that a certain vitamin is crucial for overall health and well-being, with the ability to reduce key markers of inflammation and promote the repair of damaged organs and tissues. This vitamin, which is often underestimated, is vitamin B12.
Dr. Joseph Chandy, who had extensive experience with B12 deficiency, highlighted the various symptoms associated with this deficiency. He emphasized that B12 plays a role in nerve function, red blood cell production, DNA synthesis, and can lead to pernicious anemia when levels are low. Dr. Chandy believed that the prevalence of B12 deficiency was underestimated and could manifest in a range of health conditions beyond anemia.2
Deficiency in B12 can impact nearly every part of the body, resulting in seemingly unrelated conditions such as:
Dr. Chandy challenged the conventional diagnosis threshold of 150 pg/mL for B12 deficiency, suggesting that symptoms should be considered even with readings above this level, such as Catharine's reading of 175.
Recent studies in Spain have also shed new light on the significance of vitamin B12.
Research conducted by a Spanish team investigated the impact of vitamin B12 on crucial inflammation markers, specifically interleukin (IL)-6 and C-reactive protein (CRP). This study explored the relationship between vitamin B12 levels and inflammation, which is known to contribute to aging-related chronic inflammation.
The study analyzed participants from a clinical trial assessing the preventive effects of the Mediterranean diet on heart disease.
Marta Kovatcheva from the University of Barcelona shared their findings, highlighting that higher levels of vitamin B12 were associated with lower inflammatory markers. The team also observed a similar relationship in aging mice.
These findings suggest a potential connection between vitamin B12 deficiency and unexplained symptoms like neurologic defects, emphasizing the importance of maintaining adequate B12 levels.3
The Spanish researchers discovered that vitamin B12 plays a critical role in cellular reprogramming, a process that mimics early tissue repair stages. B12 depletion was found to hinder gene function, affecting tissue repair efficiency.
B12 is essential for methylation, which regulates gene expression, including those involved in tissue repair. Adequate B12 levels are crucial for effective methylation, ultimately supporting tissue repair processes. Supplementing B12 significantly enhanced gene function and reprogramming efficiency in their studies with mice.
These findings were validated using an ulcerative colitis model, demonstrating the benefits of B12 supplementation in supporting cellular reprogramming and tissue repair.4
This research, alongside Dr. Chandy's clinical experience, emphasizes the importance of monitoring B12 levels regularly and recognizing symptoms of deficiency.
Dr. Chandy outlined critical symptoms associated with B12 deficiency, including tiredness, depression, hair loss, and neurological issues. B12 deficiency can affect individuals of all ages, with malabsorption being a common cause even among meat eaters.
It is essential for individuals, especially those following plant-based diets, to be vigilant about B12 intake to prevent deficiency-related symptoms.
During your next medical checkup, consider requesting a vitamin B12 level test, along with assessing your vitamin D levels. Deficiencies in these vitamins are common and can present symptoms resembling various illnesses. Ensuring optimal levels of these vitamins is a simple step towards maintaining good health.
