Do we need vitamin B12?

Vitamin B-12, also known as cobalamin, is a water-soluble vitamin involved in metabolism.

How many forms of Vitamin B12 are there?

Vitamin B12 (cobalamin) is the largest and most complex vitamin out there. It is unique because it is the only vitamin that contains a metal ion, cobalt (hence its name).

The molecule that is attached to the cobalamin is called a donor. The two most common donors in supplements are cyanide (making the type of B12 known as cyanocobalamin, or cyano B12) and methyl (making methylcobalamin, or methyl B12). Two other forms you may find are hydroxocobalamin and adenosylcobalamin.

Cyanocobalamin is a manufactured form of vitamin B-12. Bacterial fermentation is used in the industry to produce cyanocobalamin by the addition of potassium cyanide in the presence of sodium nitrite and heat. Once consumed, cyanocobalamin is converted to the biologically active adenosyl or methyl B-12. The two bioactive forms of vitamin B-12. Some individuals lack the enzymatic machinery to convert cyanocobalamin to its metabolic active forms. We at Frunutta have provided our customers with the options of both forms.

How to Absorb Vitamin B12 Without Taking a Shot

Now, whether you chew, drink, or swallow your vitamin the biggest issue is that the vitamin must survive the stomach acids and then the pancreatic fluids introduced in the small intestine, get absorbed by the intestine and finally survive the liver-bypass metabolism that all food must go through when swallowed.

Minimal of the original vitamin that was swallowed remains to be absorbed. If that was not bad enough vitamin B-12 requires to be bound to a protein called Intrinsic Factor (IF) to be absorbed into our body. As we age our body makes less and less IF and hence, we absorb less B12. Many complain of chronic fatigue or tiredness as they reach their 30’s, 40’s and 50’s which worsens with advancing age.

What is your best option if you do not want to get a B-12 shot in the butt? An excellent source of under the tongue B-12 currently available in the market allows bypass of the harsh environment of the gut or the need for attachment to IF. Under the tongue B-12 is absorbed directly into the bloodstream by osmosis as described above without the need of the Intrinsic Factor (IF). 

Summary

Cyano B12 is a cheap, synthetic, inactive form of B12 that is made with a cyanide donor and is used commercially. It is the most stable form because the cyanide molecule has the greatest attraction to the cobalamin, so it protects it from conditions like very high temperatures. In fact, the average person in good health will not go wrong with either, remember getting more B12 can never be a bad thing. Methylcobalamin is one of the two active forms of vitamin B12.
