Vitamin B12 is a water-soluble vitamin which
means it dissolves in water and travels through our bloodstream and this can be a good thing
because if we take too much it means that any excess or unwanted amounts are excreted
in our urine. B12 has many important roles in the body which
includes playing a vital role in the normal functioning of the brain and the nervous system
and in the formation of red blood cells. Our body produces millions of red blood cells
every minute but if we don’t have enough vitamin B12, cells cannot multiply properly. So as we can see having adequate levels of
vitamin B12 is absolutely crucial for health. So what are the symptoms of not having enough
B12? Well there are a wide variety of symptoms. Some of the most common are a sore and red
tongue, mouth ulcers, pins and needles and tingling, depression, fatigue and memory problems
to name just a few. So how much vitamin B12 should we be taking
and why? Well let’s here now from Dr Joel Fuhrman….The
B12 needs for vegans are higher than the B12 needs for a meat eater. In other words these meat eaters are getting
animal products at almost every meal so they’re taking a little B12 at each meal when you’re
on a vegan diet people are taking a pill once a day and the ability of the body to absorb
B12 at one moment in the day is limited so that if you’re going to take B12 in a supplement
then the RDI of 4mcg a day is not sufficient. You need to take 100or 200mcg a day so by
diffusion we can get higher amounts in the bloodstream because we’re only taking it
at one time. Intrinsic factor can only absorb about 2mcg
of B12 and that’s not sufficient and that’s at one time. So we get the rest by diffusion and we take
a higher dose the 2% of the total dose we can get by diffusion assures us we’re getting
enough B12. So I’m suggesting that vegans take a much
higher dose of B12 than is conventionally recommend to the population at large.
