Best B12 Supplements

B12 Supplements.

Have you ever wondered why red blood cells are so important?

If that's a yes, or no, let's highlight the reason anyways. We all need red blood cells to be produced by our body to transport oxygen from our lungs to other parts of our body. If we didn't have enough red blood cells, we could put ourselves at risk of anemia and many other conditions. One way of increasing our blood cells is by making sure we have enough b12 in our bodies, and that is often done the best using a form of b12 supplement. But, before we delve into the supplement part, let's explore B12.

What is B12?

B12 is an essential vitamin required by our body. Its primary purpose is to help keep our body's blood cells and nerves healthy and help make DNA in most cells. It also stops you from having a type of anemia known as megaloblastic anemia, which prevents you from becoming too weak and tired. Vitamin B-12 is also one out of eight B vitamins that allow your body to convert food into glucose to provide you with energy. It also helps your body to regenerate bone marrow and line your gastrointestinal and respiratory tract. Plus, it contributes to a healthier nervous system and protects your spinal cord.

How does vitamin B12 work?

Vitamin b12 binds to an intrinsic factor that is made in the stomach. However, it must be available in high amounts for your body to absorb b12 effectively. If your body does not have enough of the intrinsic factor, it could contribute to a b12 deficiency.

Conditions that can be treated

  • Irritability: Vitamin b12 can help contribute to a better mood, allowing you to feel less irritable and alleviate certain symptoms of depression.
  • Pins and needles: Vitamin B12 creates a substance known as myelin which acts as a protective coat against the nerves and stops them from being damaged.
  • Disturbed vision: This vitamin, alongside other B vitamins, has proven effective in helping better your eye health. They help reduce the inflammation in your eyes and reduce levels of a chemical known as homocysteine which can contribute to macular degeneration.
  • Cyanide poisoning: A natural type of b12 known as hydroxocobalamin is administered by injection to treat cyanide poisoning.

These are just a few conditions that vitamin b12 can treat. To know more, please check out our top 10 list of Vitamin B-12 supplements.
