Understanding Different Types of Vitamin B12 Supplements

I thought that Vitamin B12 or Vitamin B12 Complex are same things but apparently its not true. Most of us as kids were from time to time given B Complex to eat incase of mouth ulcers or after an bacterial infection, it did not occur then or even recently that Vitamin B 12 Supplement itself comes in four types, mostly 2 types are prescribed Cyanocobalamin and Methyl cobalamin.

  1. Cyanocobalamin is a synthetic version of vitamin B12 that's commonly used in supplements and fortified foods. While it's less expensive than methyl-B12, its bioavailability is lower due to the presence of cyanide, which can be toxic in high amounts.
  2. Methylcobalamin is a naturally occurring form of vitamin B12 that's found in animal-based foods such as meat, fish, poultry, eggs, and dairy products. This form of vitamin B12 has been shown to have greater bioavailability compared to synthetic forms like cyanocobalamin. Methyl-B12 is also considered more stable and less likely to degrade over time.

Self medication is not recommended, trying to improve your diet should be the first option, yet if you feel the need consult your healthcare provider.
