The Single Greatest Daily Energy Booster Since the Discovery of Coffee

The odds are good you are deficient in this "energy vitamin" discovered by natural doctors.
Vitamin B12 is known as the “energy vitamin,” and it is essential for
many critical functions in your body, including energy production,
supporting your immune system, and helping to regulate the formation of
red blood cells.* Recent studies from the US Framingham trial show that
one in four adults in the US are deficient in this vitally important
nutrient and nearly half of the population has suboptimal blood levels.
Vitamin B12 is present only in animal sources of food--which is one of
the reasons I advise against being a strict vegetarian or a vegan. This
deficiency can result in less than optimal nervous system function, a
tendency toward nervousness, and even less-than-optimal eye health.*
How You Get Vitamin B12 Deficient
The older you get the more likely you are to have a vitamin B12
deficiency. The two ways that you become deficient in vitamin B12 are
from not getting enough in your diet and from losing the ability to
absorb it.
I recently visited India which is primarily a vegetarian based culture
and current studies there show about 80% of the adults are deficient in
vitamin B12. However, vegans are not the only ones who can become
vitamin B12 deficient.
The older you get the more your digestive system breaks down,
especially if you have been following the standard American diet.
Specifically the lining of your stomach gradually loses its ability to
produce hydrochloric acid which releases vitamin B 12 from your food.
The use of antacids or anti ulcer drugs will also lower your stomach
acid secretion and decrease your ability to absorb vitamin B 12.
Infection with Helicobactor pylori, a common contributor to stomach
ulcers, can also result in vitamin B12 deficiency.
However the main cause of vitamin B 12 deficiency is a term researchers
call food-cobalamin malabsorption syndrome. Cobalamin is the scientific
term for vitamin B12. This typically results when your stomach lining
loses its ability to produce intrinsic factor which is a protein that
binds to vitamin B12 and allows your body to absorb it at the end of
your small intestine.

intake to its intestinal absorption. Endocytic receptors and proteins
responsible for vitamin B12 intestinal absorption include cubilin
(CUBN), amnionless (AMN), receptor-associated protein (RAP) and megalin
(LRP-2). The membrane megalin/transcobalamin II (TCII) receptor complex
allows the cellular uptake of cbl. Lysosomal-mediated degradation of
TCII and subsequent release of free cbl is essential for vitamin B12
metabolic functions. MS: methonine synthase; THF: tetrahydrofolate;
MTHFR: methyltetrahydrofolate reductase; MCM: methylmalonyl coA mutase.
