Vitamin B12 is essential for a wide range of critical functions, particularly for nerve health, energy production, and cellular function. According to Anthony William, the combination of adenosylcobalamin and methylcobalamin is the ideal form of B12 supplementation. He stresses that many people are deficient in this vital nutrient due to poor absorption, even if their blood tests show normal levels.

The combination of adenosylcobalamin and methylcobalamin is essential for maintaining and repairing the nervous system. Anthony William emphasizes that chronic illnesses, particularly those related to viral infections like Epstein-Barr Virus (EBV), can damage nerve cells, leading to issues like neuropathy, brain fog, and fatigue. B12 helps heal and protect these nerves.
B12 is necessary for converting food into usable energy at the cellular level. Adenosylcobalamin specifically plays a key role in the mitochondria (the powerhouse of the cell), helping to create ATP (adenosine triphosphate), which fuels the body’s energy needs.
B12 supports the repair of damaged cells and is involved in DNA synthesis, making it vital for maintaining healthy tissues and organs. It also helps remove homocysteine from the blood, reducing oxidative stress and inflammation.
B12, especially methylcobalamin, is critical for cognitive function, mood regulation, and emotional well-being. Chronic deficiency can lead to memory issues, difficulty concentrating, and mood disorders such as anxiety and depression, which William ties to viral neurotoxins impacting the brain.
B12 assists the liver in detoxifying harmful substances, particularly heavy metals. This is essential since the Medical Medium emphasizes that heavy metal toxicity exacerbates chronic illnesses and viral activity. Methylcobalamin is especially important in detoxifying pathways.

Strengthening the Body’s Energetic Shield: Anthony William often speaks about B12 as a powerful protector of the body’s energetic field, especially for those dealing with chronic viruses that drain energy and vitality. By supporting nerve health and detoxifying the body, B12 helps create a sense of grounding and energetic protection.
Other Key Points:


Unfortunately, due to the nutrient depletion of our soil, our food does not contain the level of nutrients that it once did thus necessitating supplementation. Externally, we are up against considerable accumulating toxin and pathogen exposure on a daily basis in addition to toxins and pathogens we inherit from our parents where we are starting life off already burdened.
This landmark study (Body Burden: The Pollution in Newborns) found an average of 200 industrial chemicals and pollutants in umbilical cord blood from 10 babies born in August and September of 2004 in U.S. hospitals. Tests revealed a total of 287 chemicals in the group. The umbilical cord blood of these 10 children, collected by the Red Cross after the cord was cut, harbored pesticides, consumer product ingredients, and wastes from burning coal, gasoline and garbage.
Supplements coupled with healing foods within an appropriately hydrated body are often essential to provide enough of a stimulus and support for you to be able to meet your healing goals.
