Why is vitamin B12 so dangerous?

Vitamin B12 is an essential micronutrient that plays a vital role in producing energy, forming red blood cells, and supporting neurological health. Although it is incredibly beneficial, vitamin B12 can also pose serious health risks when it is taken in excessive amounts.
Vitamin B12 is naturally found in animal-sourced foods — such as meat, poultry, eggs, and dairy products — and can be taken in supplement form.
Taking more vitamin B12 than the recommended amount can lead to a buildup of the vitamin in the body, resulting in a variety of symptoms and adverse health effects.
One of the most serious risks associated with taking too much vitamin B12 is vascular damage, or damage to the blood vessels and arteries.
When taken in excess, vitamin B12 can increase the levels of homocysteine in the body, resulting in an increased risk of stroke, heart attack, and other cardiovascular diseases.
In addition to cardiovascular risks, taking too much vitamin B12 can also lead to nerve damage. Large doses of vitamin B12 can cause an imbalance in the nervous system, resulting in numbness and tingling in the extremities, as well as weakness and fatigue.
In order to avoid potential adverse health effects from taking too much vitamin B12, it is important to only take the amount recommended by a doctor or nutritionist.
Most individuals need about 2.4 mcg of vitamin B12 daily, and higher doses may be recommended for individuals with specific medical conditions. For most people, the recommended dietary allowance (RDA) for vitamin B12 is easily achieved through dietary sources alone.
Additionally, individuals taking vitamin B12 supplements should ensure that they are taking the appropriate form; the bodies of some people have difficulty absorbing certain forms of vitamin B12.
It is important to remember that, like many vitamins and nutrients, too much of a good thing can turn bad. Although vitamin B12 is incredibly beneficial, it is important to only take the amount recommended by a doctor to ensure optimal health.
Too much vitamin B12 can cause serious health risks, so it is best to consult a qualified health professional for advice on how much to take.
