Best 10 Benefits of Vitamin B12

Vitamin B12, also known as cobalamin, aids in multiple bodily functions such as the production of hemoglobin, cognitive function, DNA synthesis, and much more. This vitamin is stored primarily in the liver and it is found exclusively in animal byproducts such as eggs, fish, pork, and dairy products. You can also obtain this nutrient from supplements. Below are ten incredible benefits of vitamin B12.

1. Improves mood

Vitamin B12 aids in regulating the nervous system, including the hormonal balance of the brain. A hormonal imbalance can lead to mood disorders such as anxiety and depression. Regular supplementation of vitamin B12 can help prevent these disorders and alleviate mental stress.

2. Prevents cognitive decline

This nutrient is vital in protecting the brain. Supplementation of vitamin B12 helps repair neurons and prevent cognitive disorders such as dementia and Alzheimer’s. Other degeneration of the nervous system is also prevented.

3. Works as an antidepressant

A deficiency in cobalamin leads to hormonal disruption in the brain and leads to depression. Studies have shown that B12 supplements can improve symptoms of depression and anxiety disorders.

4. Promotes cardiovascular health

Homocysteine is a chemical that, in high levels, damages blood vessels and contributes to atherosclerosis, heart attack, stroke, and more. Regular intake of vitamin B12 regulates homocysteine levels, thus preventing cardiovascular issues such as these.

5. Rejuvenates hair

Balding or thinning? B12 supplements can help. This vitamin increases cell production and speeds the growth of healthy hair. Hair is healthier, thicker, and less prone to breakage.

6. Aids in gastrointestinal processes

Vitamin B12 aids in the digestive process by assisting in breaking down complex compounds into more easily absorbed substances. It produces numerous enzymes that promote the growth of healthy bacteria and aids in digestion. Additionally, B12 is beneficial in preventing gastrointestinal diseases such as irritable bowel syndrome.

7. Supports fetal health

Cobalamin is responsible for DNA synthesis in the womb. Proper intake of vitamin B12, coupled with folate, has been shown to lower the chance of birth defects.

8. Promotes healthy skin

Vitamin B12 plays an essential role in cell production and rejuvenation, which is necessary for cell rebirth and keeping skin fresh. This helps keep skin glowing and prevents symptoms such as dryness, acne, inflammation, and rosacea.

9. Relieves pain

Clinical studies point to vitamin B12 as being an effective pain reliever. Patients with chronic pain in their legs, neck, and back demonstrated marked improvement in symptoms after consuming regular B12 supplements.

10. Produces red blood cells

This vitamin is necessary in producing and regulating the amount of red blood cells in the body. B12 supplements also assist in the transportation of oxygen throughout the body and ward off blood-related disorders such as anemia.
