Cobalt Health Benefits


cobaltCobalt is an essential trace element that plays a vital role in the health of humans and animals. It is a component of vitamin B12 (cobalamin), which is necessary for various biological processes in the body.

Health benefits of cobalt:

Vitamin B12 Synthesis: Cobalt is a central component of the vitamin B12 molecule. Vitamin B12 is essential for the synthesis of DNA, the proper functioning of nerve cells, and the formation of red blood cells. It is also involved in the metabolism of fatty acids and amino acids.

Red Blood Cell Formation: Cobalamin, derived from vitamin B12, is necessary for the formation of red blood cells in the bone marrow. Red blood cells are responsible for carrying oxygen from the lungs to various tissues and organs.

Nervous System Function: Vitamin B12 is crucial for the maintenance of the nervous system. It is involved in the production of myelin, a protective sheath that covers nerve cells and facilitates proper nerve signal transmission. Deficiencies in vitamin B12 can lead to neurological symptoms such as numbness, tingling, and cognitive impairments.

Energy Production: Cobalt, as a component of vitamin B12, is involved in the metabolism of carbohydrates, fats, and proteins. These macronutrients are essential for energy production in the body.

Cell Division and Growth: Vitamin B12 is necessary for proper cell division and growth. It aids in the synthesis of new cells and tissues, supporting overall growth and development.

Healthy Skin and Hair: Cobalt, along with other B vitamins, contributes to the health of the skin, hair, and nails. It is involved in the maintenance of healthy skin cells and hair follicles.

DNA Synthesis and Repair: Cobalt’s role in vitamin B12 is linked to the synthesis and repair of DNA, the genetic material of cells. This is important for maintaining overall cellular health and preventing genetic mutations.

It’s important to note that while cobalt is essential for health, like many nutrients, it is required in very small amounts, and excessive intake can be harmful. Deficiencies in vitamin B12 can lead to health issues such as anemia, nerve damage, and cognitive impairment. However, excessive intake of cobalt can potentially lead to toxicity. Most people can obtain sufficient cobalt through a balanced diet that includes sources of vitamin B12, such as meat, dairy products, eggs, and fortified foods. If you have concerns about your cobalt intake or overall nutritional status, it’s recommended to consult a healthcare professional.


Cobalt is naturally present in various foods and can be obtained from both animal and plant sources. Here are some common dietary sources of cobalt:

Animal Products:

Meat: Especially organ meats like liver and kidney.

Seafood: Fish and shellfish, including salmon, tuna, mackerel, and crab.

Dairy Products: Milk, cheese, and yogurt.

Eggs: Egg yolks contain cobalt.

Plant-Based Sources:

Fortified Foods: Some plant-based foods are fortified with vitamin B12, which contains cobalt. This includes fortified cereals, plant-based milk alternatives, and nutritional yeast.

Seaweed: Certain types of seaweed can contain cobalt.

Legumes: Lentils, chickpeas, and other legumes contain small amounts of cobalt.

Nuts and Seeds: Nuts like almonds and sunflower seeds contain trace amounts of cobalt.

Whole Grains: Whole grains such as oats, brown rice, and quinoa contain some cobalt.

It’s important to note that the primary dietary source of cobalt is through the consumption of vitamin B12-rich foods, as cobalt is a component of the vitamin B12 molecule. Vitamin B12 is predominantly found in animal products, which makes it challenging for strict vegetarians and vegans to obtain adequate amounts solely from their diets. In such cases, fortified foods or vitamin B12 supplements are often recommended to prevent deficiency.

Keep in mind that cobalt is required in very small amounts, and a balanced diet that includes a variety of nutrient-rich foods can help ensure that you meet your cobalt and vitamin B12 needs. If you have specific dietary concerns or are considering making significant changes to your diet, it’s advisable to consult a healthcare professional or registered dietitian.
