Progressive Labs B-12 Intrinsic Factor Supplement, 60 Tablets

Why Intrinsic Factor Matters for B12 Absorption

Discover Progressive Labs B-12 — Intrinsic factor is a protein produced in the stomach that binds to vitamin B12, enabling its absorption in the small intestine. Without adequate intrinsic factor—often due to ageing or certain autoimmune conditions—B12 supplements may pass through the body unused. This formula also contains pepsin, an enzyme that aids protein digestion and supports gastric function. Together, these ingredients help normalise gastric secretions and maintain a healthy digestive environment.

What Is Vitamin B12 and Why Do You Need It?

Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for red blood cell formation, neurological function, and DNA synthesis. It is naturally present in animal products, so supplementation is important for those with dietary restrictions or absorption difficulties. Maintaining adequate B12 levels supports energy metabolism and the health of your nervous system.

Key Benefits of Vitamin B12

Vitamin B12 contributes to normal energy-yielding metabolism, helping convert food into usable energy. It supports the normal function of the nervous system and plays a role in the formation of red blood cells. B12 also aids homocysteine metabolism, which is important for cardiovascular health. By including intrinsic factor, this supplement ensures that B12 is effectively absorbed in the digestive tract.

Who Should Take a Vitamin B12 Supplement?

Individuals at risk of B12 deficiency include vegetarians and vegans, older adults with reduced stomach acid, those with gastrointestinal disorders like Crohn's or coeliac disease, and people who have undergone weight loss surgery. Additionally, long-term use of acid-reducing medications can impair B12 absorption. If you fall into any of these categories, a high-quality B12 supplement with intrinsic factor may be beneficial.

How to Choose the Best B12 Supplement

When selecting a B12 supplement, consider the form (methylcobalamin vs. cyanocobalamin), dosage (typically 500–5000 mcg), and additional ingredients that support absorption. This product stands out by providing intrinsic factor and pepsin, making it ideal for those with absorption concerns. It comes in a convenient 60-tablet bottle with easy-to-swallow tablets.
