Vitamin B12 is found in meat, fish, milk and eggs.
These days, vitamin B12 is added to meat replacements in small quantities. So be aware that if you eat little or no meat replacements, you will have to supplement vitamin B12.
The form of vitamin B12 that is added to most meat replacements is cyanocobalamin B12. This the cheapest form of vitamin B12 and has to go through a complex process in order to become biologically active. Research has shown that only 2% of consumed cyanocobalamin B12 is absorbed.
Do you recognise symptoms of a vitamin B12 deficiency in yourself? Then there is a good chance you are not absorbing the cyanocobalamin that is added to meat replacement products and it is advisable to start a test treatment with active vitamin B12 for example, use the Standard Package.
Note: Many vegetarians and vegans add spirulina (an algae), tempeh ; (fermented soy) or nori (a seaweed) to their diet, in the belief that these plant-based foods contain vitamin B12. However, they only contain an analogue of B12 a non-active form of B12. The human body is unable to convert this into an active form.1 2 3
