Are you getting enough B12, and is it the right type? These are very important questions, especially for those on a Vegan diet as the consequences of B12 deficiency can be very serious.
Vitamin B12 is an essential nutrient that is required in the human body to sustain normal functioning and the only way we can get it is through our diet as the body cannot synthesise it on its own.
The only valid source of Vitamin B12 is from meat and animal products. Therefore Vegans in particular do need to supplement with B12 or eventual suffer the consequences of B12 deficiency.
The vast majority of Vitamin B12 supplements are made from Cyanocobalamin which is chemically synthesised and does not occur in nature. Cyanocobalamin must be processed by the body (Methylated) before it can be used and this leaves a small toxic residue of Cyanide that the body must eventually get rid of.
Most experts now agree that it is Methylcobalamin that is the more ideal B12 as this can be immediately used by the body and does not leave any toxic residue.
So make sure you read the labels very carefully before buying Vitamin B12 supplements as your long term health may well depend upon it.
