Increased Need for vitamin B12 with age

[Guest guest]

Absorption of vitamin B12 is dependent on the ability of the digestive

tract to release intrinsic factor, which combines with vitamin B12 to

make it ingestable. The ability of the digestive tract to release

intrinsic factor was shown to decrease with age, according to many

surveys. This means that the required intake of vitamin B12 increases

with age, and since vitamin B12 is only present in animal products, it

means that older people are more meat-dependent than younger people.

Vitamin B12 supplements like Neurorubina are also advisable.
