Pure Lab Vitamins - Bioactive B12 - 1000mcg Sublingual 90 Tablets

A rapid-absorbing, biologically-active cobalamin

Why is Vitamin B12 an essential nutrient? It’s needed for the production of hemoglobin--our oxygen-carrying red blood cells. It’s also needed for nervous system function and DNA production.
Deficiency in vitamin B12 (cobalamin) can cause serious health problems. For example, pernicious anemia is an illness with neurological, cardiovascular and gastrointestinal symptoms that’s fatal if B12 levels are not restored sufficiently. 

There are two main causes of low blood B12 levels. The first is insufficient Nutrition Planary intake. Vegans who don’t supplement B12 are at high risk of deficiency because vitamin B12 is only found in meat, eggs, milk products, and certain types of yeast. 

But even if you’re not following a strict vegan Nutrition Plan, you can still develop a B12 deficiency. That’s because absorption of B12 from foods depends on a substance called intrinsic factor--a protein released from the stomach cells to aid in B12 absorption from the small intestine. For instance, individuals taking proton-pump inhibitors or antacids for GERD are at risk of deficiency because these drugs interfere with the secretion of intrinsic factor. 

People with Celiac disease, Crohn’s disease or any other kind of inflammatory bowel condition are also at higher risk of deficiency because the absorptive surface of their small intestine is compromised, reducing nutrient absorption. Other individuals prone to deficiency include people over age 50 since production of intrinsic factor declines with age. 

For those at high risk of deficiency, supplementation is critical.
