• Nutritional yeast

Cyanocobalamin, on the other hand, is made in labs. It’s found in:

• Fortified breakfast cereals
• Synthetic dietary supplements
• Multivitamin preparations
• Fortified plant-based milk alternatives

*The bioavailability of vitamin B12 from dietary supplements is approximately 50% higher than from food sources.*

People who don’t eat meat or animal products might need cyanocobalamin supplements. They are hard to find in plant-based foods. Always talk to a doctor to find the right vitamin B12 for you.

Absorption Mechanisms in the Body

Vitamin B12 absorption is a complex process. It involves detailed digestive and cellular mechanisms. Understanding how our body processes this essential nutrient is key.

• Active absorption (intrinsic factor-dependent)
• Passive absorption (diffusion)

Digestive Process

During digestion, the body transforms vitamin B12 in amazing ways. Whether you take cyanocobalamin or methylcobalamin, specific biochemical steps prepare it for absorption.

The main steps are:

1. Removing molecular groups (methyl or cyanide)
2. Releasing the pure cobalamin molecule
3. Preparing for cellular uptake

Cellular Uptake

The absorption of cobalamin depends on intrinsic factor, a protein from stomach cells. Research shows a precise ratio of 1 intrinsic factor to 1 vitamin B12 molecule during active absorption.

“The body’s ability to absorb vitamin B12 is a testament to its complex metabolic machinery.”

Studies show that different B12 forms are absorbed at similar rates. Genetic and age-related factors greatly affect how well each person absorbs B12.
