Eligen B12

The Science Behind

The Eligen Difference

Eligen B12 is not a dietary supplement, it’s an FDA-classified non-prescription medical food. What makes Eligen more effective than other oral solutions is that it contains innovative SNAC (Salcaprozate Sodium) technology, a patented vitamin delivery system.


SNAC utilizes “carriers” to help chaperone B12 through the gastrointestinal tract and deliver B12 directly into the bloodstream, significantly increasing the vitamin’s bioavailability.


This revolutionary absorption-enhancing technology is also utilized in prescription drugs, including Rybelsus®, the first and only oral glucagon-like-peptide-1 (GLP-1) receptor agonist, an FDA-approved prescription medicine for treating adults with type 2 diabetes.

How SNAC Technology Works

SNAC technology carries B12 molecules, transports B12 across the gastric lining, and delivers the vitamin directly into the bloodstream, regardless of intrinsic factor.

Intrinsic factor is a naturally occurring protein found in the body that helps with the absorption of B12. During the digestive process, intrinsic factor binds to B12 molecules and helps them travel to the intestines where the vitamin is ultimately absorbed into the bloodstream.

B12 deficiency may be caused by a range of conditions, often involving a lack of natural intrinsic factor. SNAC carriers in Eligen simulate intrinsic factor, making it possible for B12 to successfully absorb into the bloodstream at higher rates.


Clinically-Proven Results

Eligen B12 is an effective, convenient and pain-free solution for those who struggle to absorb or maintain healthy levels of B12. It is a once-daily oral pill that keeps B12 levels steady all month long. Clinical studies have shown that Eligen B12:

Normalizes B12 levels as effectively as IM B12 injections

Absorbs 2.5x better than common oral supplements
