What is the best form of B12 to take?

You may be looking for a Vitamin B12 supplement and asking what form is best?  There are quite a few options to consider, starting with the most common:

  • Cyanocobalamin
  • Hydroxycobalamin (also known as hydroxocobalamin)
  • Methylcobalamin
  • Adenosylcobalamin

Vitamin B12 is essential for energy production, neurological function, and overall health, so it makes sense why you wouldn't want to waste your time and money on less effective forms. Choosing the best form of B12 can be confusing due to the variety of options available.  Though cyanocobalamin and hydroxycobalamin are the most commonly available forms, because they are very stable and hence less expensive, you would be better off leaving them on the shelf.

Methylcobalamin and adenosylcobalamin stand out as superior choices. While the other options mentioned are less expensive, these are inferior forms due to the fact that the body only utilizes B12 as methylcobalamin and adenosylcobalmin.  The cheaper forms can be converted in the body to the active forms, but this process is limited, so you are sacrificing effectiveness.  It makes sense to provide the active forms to the body, and research confirms this logic.

Methylcobalamin supports the methylation cycle, which is crucial for detoxification and brain health, while adenosylcobalamin aids mitochondrial energy production. Together, they provide comprehensive support for the body’s needs.  Activated B12 Oil by Spectrum Sciences includes both these forms in equal amounts.

For individuals with autism, B12 deficiency is particularly concerning. Research has shown that children with autism often have impaired B12 absorption due to gastrointestinal issues and gut dysbiosis. Studies indicate that methylcobalamin supplementation can improve symptoms such as communication skills and social behaviors by enhancing methylation and glutathione redox capacity. This highlights the critical role of B12 in addressing metabolic abnormalities linked to autism.

Unfortunately, oral B12 supplements often fall short due to limited absorption in the gut. Factors like gastrointestinal disorders or medications can block the proper uptake of B12, making high-dose oral supplements inefficient for many people. While injections bypass these barriers and deliver B12 directly into the bloodstream, they can be invasive and inconvenient. 

Transdermal delivery offers an innovative solution to these challenges. Spectrum Sciences Activated B12 Oil combines methylcobalamin and adenosylcobalamin in a topical serum that penetrates deeply into the skin to deliver B12 directly into the bloodstream. This method ensures consistent absorption without needles or prescriptions, making it a practical and cost-effective alternative for those struggling with functional B12 deficiencies.

If you’re looking for an effective way to restore your B12 levels, transdermal supplementation may be the answer. It avoids the pitfalls of oral absorption and provides a convenient, non-invasive option for maintaining optimal health—especially for individuals with autism or other conditions that impair B12 metabolism.
