B-12 Intrinsic Factor - 60 Capsules

Vitamin B12‚ also known as cobalamin‚ is a water-soluble vitamin that plays a major role in various aspects of human physiology. It acts as a cofactor (or “helper molecule”) in the metabolism of fatty acids‚ such as those used for nerve myelination‚ the metabolism of homocysteine (a molecule associated with cardiovascular health)‚ and the synthesis of nucleic acids. Nucleic acids are required for every dividing cell in the body‚ especially red blood cells and the cells of the gastrointestinal tract.

Since it can’t be created naturally by your body‚ you have to rely on your diet and supplements to ensure adequate levels of vitamin B12. The only natural sources of the vitamin are animal products‚ such as liver‚ eggs‚ meat‚ fish‚ and milk. The elderly are at particularly high risk of developing vitamin B12 deficiency‚ as are people suffering from certain gastrointestinal diseases that inhibit nutrient absorption.

Vitamin B12 deficiency can deplete your body’s supply of red blood cells‚ affect cardiovascular and neurological health‚ and leave you feeling weak and constipated. That’s why taking a supplement like Progressive Labs’ B-12 Intrinsic Factor may be a good idea for you. In addition to its usefulness in treating or preventing vitamin B12 deficiency‚ this type of supplement may help you sleep better.

Each capsule of B-12 Intrinsic Factor provides you with a subset of high quality nutrients:

• Vitamin B12‚ which helps your brain and nervous system function properly


• Folate‚ which helps your body metabolize B12


• Pig intestine‚ stomach‚ and pancreas extracts‚ which may help support the absorption of vitamin B12

The recommended dosage of B-12 Intrinsic Factor by Progressive Labs is one capsule daily‚ unless otherwise directed by your health care provider. Medical counseling and follow-up is advised if you have vitamin B12 deficiency.
