What Are Methylated Vitamins and Do You Need Them?

If you've been shopping for multivitamins lately, you've probably seen terms like methylfolate, methylated B12, or methylated vitamins.

These nutrient forms have become increasingly popular, and for good reason. As people become more interested in nutrient quality and how different vitamin forms function in the body, methylated vitamins have become a highly discussed topic.

That's because researchers now understand that not all vitamin forms are exactly the same. Some forms require additional conversion steps in the body before they can be used, while others are already in biologically active forms.

That's where methylated vitamins come in.

What are methylated vitamins?

The word "methylated" refers to a process called methylation, which happens constantly throughout the body.

Methylated vitamins are nutrient forms that already contain a methyl group, a small chemical structure involved in many essential biological processes. Because of this, methylated forms are already biologically active and don't require the same conversion steps as some other vitamin forms.

There are two well-known methylated vitamins:

• Methylfolate (5-MTHF), the active form of folate (vitamin B9)
• Methylcobalamin, one of the active forms of vitamin B12

Why does methylation matter?

To use nutrients, your body often has to convert them into forms that can be used in normal biological processes.

Methylated vitamins essentially skip part of that process because they're already in forms the body recognizes and uses.

That's why methylated forms have become a growing area of interest in nutrition science and supplement formulation.

Methylfolate vs. folic acid: what's the difference?

Folate is a B vitamin naturally found in foods such as leafy greens, legumes, and citrus fruits.

Methylfolate (5-MTHF) is the primary form of folate found circulating in the bloodstream and is already in its biologically active form.

Folic acid, meanwhile, is a form commonly used in supplements and fortified foods.

Importantly, both folic acid and methylfolate provide vitamin B9 (folate). The difference is that folic acid must be converted into active forms before the body can use it, while methylfolate is already biologically active.

Because methylfolate is ready to use, many supplement companies now choose it as their preferred folate ingredient.

What does MTHFR have to do with methylated vitamins?

Interest in methylated vitamins often leads to discussions about the MTHFR gene.

The MTHFR gene provides instructions for making the methylenetetrahydrofolate reductase (MTHFR) enzyme, which helps the body process folate. Research suggests that many people carry variations in this gene that can affect how efficiently the body converts folate into active forms.

In fact, some estimates suggest that up to 50% of people may have an MTHFR gene variant that influences folate metabolism—and some may not even know it. Because methylfolate is already in an active form, many people seek it out just in case they have the variant.

What about methylated B12?

Vitamin B12 supports healthy red blood cell formation and healthy nervous system function.*

One of the most studied active forms of B12 is methylcobalamin.

Like methylfolate, methylcobalamin is one of the active forms of vitamin B12 and is increasingly included in holistic multivitamin formulations.

What should you look for in a high-quality methylated multivitamin?

Methylated vitamins have become a popular part of modern multivitamin formulation, but they're only one piece of the puzzle.

A thoughtfully formulated multivitamin considers the forms of all nutrients used, the amounts provided, and how those nutrients each work to support the body. Review the Supplement Facts panel on products you're considering to make sure they contain the combination you want.

Methylated folate and methylated B12

Look for methylfolate and methylcobalamin if these nutrient forms are important to you. Methylfolate may be listed as 5-MTHF, L-methylfolate, or other similar wording.

Methylcobalamin may be listed as part of the Vitamin B12 description.

More than one nutrient upgrade

The best multivitamins don't stop with methylation.

At New Chapter, methylated B vitamins are part of a broader philosophy of formulating with nutrient forms chosen to work in harmony with your body. That's why many of our multivitamins also include key nutrients fermented with probiotics and whole foods, helping to provide nutrients the body can recognize as food.

A formula designed for your life stage

A great multivitamin should also reflect your body's needs.

Women's, men's, prenatal, 40+, and 55+ multivitamin formulas all have different nutritional priorities. That's why New Chapter designs multivitamins around specific life stages rather than taking a one-size-fits-all approach.

In the end, the best methylated multivitamin is one that combines high-quality nutrient forms and is tailored to support your stage of life. Check in with your healthcare provider if you have questions about the best multivitamin for you.

A practical example: New Chapter multivitamin tablets

New Chapter multivitamins are intentionally crafted with nutrient forms chosen to work in harmony with your body.

That's why New Chapter multivitamin tablets include methylfolate and methylcobalamin (methylated B12), alongside other carefully selected nutrient forms such as fermented vitamins and minerals. Our multis are so gentle you can even take them on an empty stomach.

The bottom line

Methylated vitamins have become increasingly popular because they provide nutrients in biologically active forms.

For many people, methylfolate and methylated B12 are appealing options because they're ready for the body to use and help support important functions throughout the body.*

When choosing a multivitamin, consider the forms being used. Methylated vitamins are one example of how holistic multivitamin formulations are becoming more thoughtful about how nutrients work with the body.
