Not All B12 is Created Equal

Not All B12 is Created Equal

Your Dr. said you need more B12. Or your friend said that she's been taking it every morning and feels amazing, but when you start searching for a supplement to buy, all you see are confusing terms like methlycobalamin and cyanocobalamin.

The water-soluble vitamin B12 (cobalamin) is an essential vitamin which means we cannot make it ourselves and must get it from food and/or supplements. It helps us sleep better, enhances metabolism, elevates mood, and contributes to brain function.

Because B12 isn't available in most fruits and vegetables but is naturally occuring in meats, shellfish, poultry, eggs, and dairy; most vegans tend to find themselves low in this necessary vitamin. Deficiency in B12 can lead to fatigue, digestive issues, and symptoms like depression and memory loss. 

This is when supplements come in handy.

Vitamin B12 supplements usually come from one of two sources - methylcobalamin, containing a methyl group, and cyanocobalamin, containing a cyanide molecule. Cyanocobalamin is the synthetic form and usually considered more cost effective. Research comparing these two forms is limited; however some studies show differences in retention. Cyanocobalamin may be absorbed better by the body, but methylcobalamin seems to have a higher retention rate (1).

At Physician Pure, we only use methlycobalamin in our PURE PREVENT immune support drink. When ingested, cyanocobalamin is converted to one of the two active forms in humans - methylcobalamin or adenosylcobalamin. However, we prefer to only take the naturally occuring form of this key vitamin instead of the version that's linked to a cyanide molecule.

Who should take B12?

As with all supplementation, it is important to consult your doctor for your needs. In general, It is recommended to supplement with B12 if you have any contributing factors that would reduce absorption of B12 from foods:

  • Anyone over the age of 50
  • Vegans, vegetarians, or those who can't eat dairy
  • Those with gene mutations like MTHFR and MTRR 
  • People on medications for heartburn
  • Anyone with gastrointestinal issues
  • People who drink alcohol regularly
