B12 Deficiency and Sugar Cravings: What Your Fatigue Is Telling You

Are you experiencing fatigue, struggling with chronic diseases, or battling intense sugar cravings?

The answer to these interconnected low grade issues might lie in understanding the role of Vitamin B12 deficiency.

Vitamin B12 is involved in multiple key physiological processes within the body, such as red blood cell production, nervous system support, energy metabolism, and brain function.

Inadequate Vitamin B12 levels not only have consequences for overall health but can also intensify sugar cravings. In this article, we will look at the relationship between Vitamin B12 deficiency, chronic diseases, and sugar cravings, and provide practical strategies to address these issues.

​

I. Understanding B12 Deficiency

A. Explaining the Role of Vitamin B12

Vitamin B12 is a water-soluble vitamin that is involved in various physiological processes within the body.

It serves as a coenzyme. In other words, it is essential for the proper functioning of enzymes involved in numerous metabolic reactions.

Here are some key functions of Vitamin B12:

1. Red Blood Cell Production: Vitamin B12 is required for the production of healthy red blood cells, which carry oxygen throughout the body. It aids in the synthesis of DNA, RNA, and heme, an iron-containing compound in hemoglobin.
2. Nervous System Support: Vitamin B12 helps to maintain the health of the nervous system. It helps in the production of myelin, a protective sheath that surrounds nerve fibers & facilitates proper nerve signal transmission.
3. Energy Metabolism: Vitamin B12 facilitates converting food into energy by assisting in the breakdown of carbohydrates, fats, and proteins. It helps in the metabolism of amino acids and the synthesis of fatty acids.
4. Brain Function: Vitamin B12 is involved in cognitive processes, including memory, focus, and overall brain function. It supports neurotransmitter production and helps regulate mood.

​

B. What are some Causes & Risk Factors for B12 Deficiency?

Vitamin B12 deficiency can arise from various factors, including: Inadequate Dietary Intake, Malabsorption Issues, Pernicious Anemia, Medications and Treatments.

Specific risk factors that may contribute to B12 deficiency include advanced age, alcohol abuse, certain gastrointestinal disorders, and a history of weight loss surgeries.

​

C. What are some Symptoms of B12 Deficiency?

Here are some common symptoms to watch out for:

• Fatigue & Weakness: Vitamin B12 deficiency can cause persistent fatigue, weakness, and a general lack of energy. You may feel tired even after getting enough rest & sleep.
• Neurological Symptoms: Nerve damage resulting from Vitamin B12 deficiency can contribute to various neurological symptoms, including:
  • Tingling Sensations & Numbness: People with Vitamin B12 deficiency may experience a “pins and needles” feeling. This can be felt in the hands and feet.
  • Balance Problems & Difficulty Walking: Vitamin B12 deficiency can affect the coordination & balance of an individual, leading to difficulties with walking or maintaining balance.
  • Memory Issues: Cognitive symptoms can manifest as memory problems, difficulty concentrating, and mental fogginess. Individuals may have trouble remembering things, organizing thoughts, or staying focused.
  • Mood Disturbances: Vitamin B12 deficiency can impact mood regulation, causing individuals to experience mood swings, irritability, depression, or anxiety.
• Pale or Yellowish Skin: Vitamin B12 deficiency lead to a decrease in the number of healthy red blood cells. This can result in pale or yellowish skin, as well as pale mucous membranes (e.g., inside of the mouth).
• Digestive Issues: Some individuals with B12 deficiency can experience digestive problems, which can include:
  • Loss of Appetite: Vitamin B12 deficiency can lead to a decreased desire to eat.
  • Nausea: Individuals may experience feelings of nausea, which can be mild to severe.
  • Constipation: Vitamin B12 deficiency can contribute to constipations.

II. The Link between B12 Deficiency and Chronic Disease

Vitamin B12 deficiency has implications for cardiovascular health, as inadequate levels may increase the risk of heart disease and stroke. B12 deficiency can also contribute to various neurological disorders, including cognitive decline and neurodegenerative diseases. Additionally, evidence suggests a connection between Vitamin B12 deficiency and autoimmune conditions.

​

III. B12 Deficiency & Sugar Cravings

Vitamin B12 deficiency, specifically, has been implicated in triggering or intensifying sugar cravings.

How?

1. Disturbed Glucose Metabolism: Vitamin B12 plays a role in glucose metabolism. Without sufficient B12, the body’s ability to efficiently utilize glucose is compromised. This can result in fluctuations in blood sugar levels and a feeling of low energy, leading to an increased desire for quick energy in the form of sugary foods. The body may crave sugar to compensate for the perceived energy deficit caused by impaired glucose metabolism.
2. Neurotransmitter Imbalance: Vitamin B12 is involved in the production and regulation of various neurotransmitters, including:
   • Dopamine: dopamine production may be compromised when B12 levels are insufficient, this imbalance in dopamine can lead to an increased desire for sugar and sweet foods.
   • Serotonin: Vitamin B12 is necessary for serotonin synthesis, impacting mood, sleep, and appetite regulation.
   • Noradrenaline: Vitamin B12 is involved in the synthesis of noradrenaline, which regulates alertness, focus, and stress responses.
   • GABA: Vitamin B12 also affects GABA synthesis, an inhibitory neurotransmitter that promotes calm & relaxation.

​

IV. Diagnostic Methods for B12 Deficiency

To address Vitamin B12 deficiency effectively, monitoring is first and foremost.

Common diagnostic tests include:

1. Blood Tests: A blood test is the primary method used to measure Vitamin B12 levels.
2. Homocysteine & Methylmalonic Acid (MMA) Tests: Elevated levels of homocysteine & MMA in the blood can indicate B12 deficiency. These tests help evaluate the functional status of B12 in the body.

While optimal B12 ranges can vary depending on individual factors, here is an example of commonly accepted optimal ranges for Vitamin B12 levels:

• Serum B12 levels: The optimal range for serum B12 levels is typically considered to be between 500 and 1,000 picograms per milliliter (pg/mL). This range is higher than the lower limit of the reference range used for normal B12 levels, which is often around 200 pg/mL.
• Active B12 (holotranscobalamin): Holotranscobalamin is the biologically active form of B12. Optimal levels of active B12 are often recommended to be above 35 picomoles per liter (pmol/L).

V. Strategies for Managing B12 Deficiency & Sugar Cravings

• Proper Hydration: Ensure adequate hydration throughout the day as dehydration can sometimes be mistaken for sugar cravings. Opt for water or herbal tea.
• Regular Bloodwork: Get your Vitamin B12 levels assessed regularly, especially if you are at risk or have a history of low B12 levels.
• Incorporate B12-Rich Foods: Meat, fish, eggs, and dairy products are rich sources of Vitamin B12. For individuals following vegetarian or vegan diets, fortified plant-based foods or B12 supplements may be necessary to meet the requirements. My favorite B12 food is nutritional yeast.
• Balanced Meals: Ensure each meal contains a balance of macronutrients (protein, healthy fats, and fiber) to stabilize blood sugar levels and reduce cravings. Focus a variety of nutrient-dense foods, including legumes, fats from whole foods, lean proteins, and plenty of fruits & vegetables.
• Healthy Substitutes: Choose natural sweeteners like monk fruit extract instead of refined sugar. Use fruits, such as berries, dates, figs, as an alternative.
• B12 Supplementation: B12 supplementation is sometimes used to address deficiency. Various supplementation options are available, including oral supplements, sublingual tablets, and injectable forms. The choice of supplementation depends on the severity & nature of the deficiency.

Conclusion:

The connection between Vitamin B12 deficiency & sugar cravings illustrate the importance of nutrient balance & the role of excellent nutrition in regulating appetite.
