Introducing Cobalamin - Filter for Healthy Blood

Vitamin B-12 is the largest and most complex of all the vitamins. It is unique among vitamins in that it contains a metal ion, cobalt. For this reason cobalamin is the term used to refer to compounds having B-12 activity. Methylcobalamin and 5-deoxyadenosyl cobalamin are the forms of vitamin B-12 used in the human body. The form of cobalamin used in most supplements, cyanocobalamin, is readily converted to 5-deoxyadenosyl and methylcobalamin.

Why Cobalamin?

Cobalamin is know to keep your red blood cells healthy. If you eat enough cobalamin, and if your body can use it properly, you make millions of nice round, healthy red blood cells every day. If you don't eat enough, or you can't use it properly, you can't make enough red blood cells, and the ones you do make are too large and fragile to work well. When you don't have enough red blood cells to carry oxygen and nutrients around your body, you develop anemia.

All your cells, not just your red blood cells, need cobalamin to grow and divide properly. For example, you need it to make all the different cells in your immune system, including white blood cells.

Cobalamin's next big role is in making the protective fatty layer, or sheath, that coats your nerve cells - sort of like insulation on electric wires. If the sheath is damaged because you don't have enough cobalamin, you start getting the equivalent of static on the line. Really bad static can interfere with your mental function - so much that people think you're senile.

Cobalamin is a team player. Working with the other B vitamins, but especially with pyridoxine and folic acid, it helps you turn the carbs, fats, and proteins in your food into energy in your cells.

Among many cobalamin supplements, Natural Timed B-12 1000mcg from NatureMost stands out for it's price and best result. We fully recommend this supplement.

What's the Recommended Dietary Allowance for Cobalamin?

The current RDA was revised by the Food and Nutrition Board (FNB) of the Institute of Medicine in 1998.

Adults ages 50 and younger: 2.4 micrograms (mcg) of vitamin B-12/day
Adults ages 51 and older: 2.4 mcg of vitamin B-12/day from supplements or fortified foods, due to the age-related increase in food bound malabsorption
Pregnant women: 2.6 mcg of vitamin B-12/day
