TriVita keeps the promise—and improves how your body uses it.

More than two decades ago, Dr. Alfred Libby challenged the standard approach to vitamin B12 supplementation—an approach that relied heavily on painful injections and inconvenient clinic visits. His work led to a meaningful breakthrough: a patented sublingual slow-dissolve delivery system designed to support absorption under the tongue. His ingenious delivery method made daily B12 support easier, gentler and more accessible… all without needles.

What Science Has Discovered Since the Original Formula

Dr. Libby’s primary contribution was not chasing a trend—it was solving a delivery problem. He recognized that how B12 enters the body matters, especially for people who struggle with absorption or want to avoid injections. His patented sublingual system addressed that challenge in a way few had considered at the time.

TriVita Members have trusted that science for decades, experiencing reliable support for energy and mental clarity through the original formula built on Dr. Libby’s innovation. Since then, however, scientific understanding of vitamin B12 forms, as well as how our bodies metabolize it, has continued to advance. And, TriVita is advancing with it to bring greater wellness to our Members.

One of the most important discoveries has been the difference between the cyanocobalamin and methylcobalamin forms of B12… Not in what the vitamin does but in how efficiently the body can use it.

Cyanocobalamin B12 must first be converted by the body into an active form before it can be used to support energy, brain function and nervous system health. That conversion happens just fine for many people—but that conversion takes time, and some people are unable to process the cyano- form due to metabolic dysfunction.

Methylcobalamin, on the other hand, is the active form of B12, meaning it is ready for use immediately. So, it works faster for people with good metabolic function… and without the need for conversion, it works for more people with poor metabolic function.

Clinicians and leading health experts commonly use methylcobalamin for that reason.

Making the switch to methylcobalamin honors Dr. Libby’s commitment to science and helps more people experience the benefits of vitamin B12 than ever before.

Everyone Benefits from the Move to Methyl

Methylation is a specific type of metabolism involved in many critical processes in the body, including:

• Energy production

• Brain chemistry

• Nervous system function

For individuals with healthy methylation function, switching to methylcobalamin does not change what B12 does, but rather how quickly it does it. Because this form of B12 is already active, the body can use it more directly, supporting faster results for energy and brain support.

For others—especially as we age—conversion efficiency can decline. With less efficient methylation, nutrients that require conversion may not work as quickly or as consistently. Methylcobalamin removes that barrier.

This allows the same trusted product to:

• Act faster for those who already benefit from B12

• Work more consistently for those with less efficient conversion

The benefit is broader… without changing the foundation of Dr. Libby’s pioneering sublingual delivery.

Why Clinicians Prefer Methyl B12

Leading clinicians and health experts use methylcobalamin most often for this reason: the methyl form is already active, immediately usable and well-suited for supporting neurological and energy-related needs.

By updating the B12 form—while keeping Dr. Libby’s patented sublingual delivery system intact—TriVita has aligned the Original B-12 formula with the same science used in clinical practice… but without the need for injections, appointments or discomfort.

Innovation That Respects the Original Science

This enhancement builds upon Dr. Libby’s scientific research:

• Same dose of vitamin B12 in a faster-acting form, with support for those with poor metabolic function

• Same patented sublingual delivery developed by Dr. Libby

• Same supporting ingredients as before

• Same commitment to quality

What has changed is the efficiency of the nutrient itself, based on what science now understands.

That is how progress is meant to work.

TriVita continues to honor Dr. Libby’s legacy by doing what he did best: following the science—wherever it leads—for the benefit of our Members.

To faster and more efficient energy and mental clarity for all!
