Pure Lab Vitamins Bioactive B12 1000mcg 60s

Methylcobalamin is the biologically-active form of vitamin B-12. Absorption of this essential vitamin depends on adequate production of intrinsic factor, secreted by a healthy stomach. However, neither dietary sources nor ordinary supplements containing vitamin B-12 will help an individual with low / no intrinsic factor secretion. Again, low stomach acid secretion and some auto-immune disorders are just some of the factors that can reduce the secretion of this special substance.

Other factors that increase one’s requirements for Vitamin B-12 include:

Advanced Age
Cardiovascular disease and stroke
Macular Degeneration of the eyes
Vega diet
Pernicious anemia
Auto-immune disorders
Celiac disease
Crohn’s Disease

Pure Lab Vitamins’ BioActive B-12 provides 1000mcg or 5000mcg of methylcobalamin per tablet. Taken sublingual (under the tongue) it’s delivered directly into the bloodstream, making it a more effective, non-invasive and direct way to replenish vitamin B-12 levels. The product is using a natural Strawberry / Kiwi flavour and is sweetened using low amounts of mannitol and xylitol, avoiding the use of sugars and artificial chemical sweeteners.
