Vitamin B12 1000mcg 90tabs from Applied Nutrition is a dietary supplement based on vitamin B12, an essential micronutrient that our bodies cannot self-produce and must therefore be taken with diet and, if necessary, supplements.
The best sources of vitamin B12 in food are those of animal origin such as meat, so those who are vegan should always include this very important nutrient.
In reality, however, there are several factors that can reduce the absorption of B12 taken with food, including the use of alcoholic beverages, metformin (a common anti-diabetic medication) and also problems with the gastric mucosa.
These latter factors are due to the fact that the B12 to be absorbed in the intestine must bind to a glycoprotein called intrinsic factor, which is in fact produced by the gastric mucosa.
As you can see, there are so many functions of this vitamin that a deficiency in it, especially if prolonged, can become a health problem. So check your dietary intake carefully, and if you don’t eat animal food, always take a supplement. Your doctor or nutritionist will be able to give you more information.
