A methylated multivitamin supplies folate and vitamin B12 in their methyl forms, methylfolate (5-MTHF) and methylcobalamin, and usually pairs them with active forms of B6 (P5P) and B2 (riboflavin-5-phosphate). It suits you if you want those forms on your label, but the standard forms aren't poor substitutes: methylfolate is absorbed at least as well as folic acid, and B12 absorption doesn't appear to differ by form.
So the real decision comes down to the B-vitamin panel. Folate, B12, B6 and B2 can each appear in different forms, and knowing what each name means makes the label much easier to compare.
What Does Methylated Mean in a Multivitamin?
"Methylated" usually means the formula includes one or more B vitamins in active, body-ready forms. Strictly, only folate and B12 are methylated; B6 and B2 appear as phosphate forms, but methylated formulas, including ours, often include them too.
| Vitamin | Common standard form | Active-form label wording |
|---|---|---|
| Folate | Folic acid | 5-MTHF, L-methylfolate |
| B12 | Cyanocobalamin | Methylcobalamin |
| B6 | Pyridoxine HCl | P5P (pyridoxal-5-phosphate) |
| B2 | Riboflavin | Riboflavin-5-phosphate (R5P) |
According to the NIH folate fact sheet, folic acid is the form used in fortified foods and most supplements, while 5-MTHF is the main form of folate circulating in your blood. For B12, methylcobalamin and adenosylcobalamin are the metabolically active forms; cyanocobalamin and hydroxocobalamin become active after your body converts them.
Our Methylated Multivitamin is a 19-in-1 capsule formula with B12 as methylcobalamin, B6 as P5P and riboflavin as R5P, alongside folate, niacin (as niacinamide), vitamins A, D3 and E, fat-soluble vitamin C, calcium, iodine and chromium, with no fillers. The serving is 2 capsules daily with food.
Who Might Prefer a Methylated Multivitamin?
A methylated multivitamin tends to appeal to people who want active-form B vitamins, people comparing folate and B12 forms closely, and people whose clinician has suggested paying attention to nutrient forms.
MTHFR comes up often when people research methylated vitamins. People with a common variant in the MTHFR gene convert folate to 5-MTHF less efficiently. The NIH describes the research on folate supplements for this group as inconclusive and says some of these people might benefit from 5-MTHF. It also notes that the CDC still recommends 400 mcg a day of folic acid, not 5-MTHF, for anyone who could become pregnant, with or without the variant. If MTHFR is your reason for shopping, that's a conversation to have with your clinician rather than a label to decode alone.
If B12 is your main reason, a consistent daily source matters more than the form. The NIH vitamin B12 fact sheet lists vegans, vegetarians and older adults among the groups more likely to run low on B12.
| Your situation | What to check |
|---|---|
| Want active-form B vitamins daily | Folate, B12, B6 and B2 forms |
| Already take separate B vitamins | Totals across every label |
| Mainly after B12 | A B12-only product may be simpler |
How to Read Folate, B12, B6 and B2 on the Label
Start with folate. The Supplement Facts panel lists folate in mcg DFE (dietary folate equivalents), and it should name the source form, such as L-5-methyltetrahydrofolate, 5-MTHF or folic acid. The DFE number is the standardized amount; the source form tells you which kind of folate is used.
The DFE figure and the actual weight of methylfolate can differ. Conversion factors for 5-MTHF haven't been formally set, and labels can use a factor of up to 1.7. Our L-Methylfolate 15mg softgels show how that reads: 25 mg DFE containing 15 mg L-methylfolate per serving.
Then look at B12. Cyanocobalamin is the most common supplement form; methylcobalamin, adenosylcobalamin and hydroxocobalamin also appear. A product isn't "methylated B12" unless methylcobalamin is on the panel.
Don't be surprised by large B12 numbers. Your body absorbs about 50% of doses under 1-2 mcg but only about 2% of a 500 mcg dose, so B12-only products carry far more than the daily requirement. Multivitamins typically list 5-25 mcg, while B12-only products typically carry 500-1,000 mcg.
B6 is next. P5P is the active coenzyme form, while pyridoxine HCl is the most common supplement form, and the NIH notes that absorption doesn't differ substantially between supplement forms. The useful question is whether the form and dose match why you're buying.
B2 gets less attention but belongs in the same check. Riboflavin-5-phosphate, also called flavin mononucleotide, is one of riboflavin's coenzyme forms; most supplements use plain riboflavin instead. If a multivitamin markets active B forms and uses R5P, that's part of the methylated-style label pattern.
Methylated Multivitamin vs B-Complex vs B12
The cleanest choice depends on what gap you're trying to fill.
A methylated multivitamin is the broadest option. It covers active B vitamins plus other vitamins and minerals in one daily product, which means fewer bottles but more overlap to check against anything else you take.
A methylated B-complex is narrower. Our Methylated B Complex is an 11-in-1 formula with methylcobalamin, P5P, R5P, folate, the other B vitamins, choline, inositol and fat-soluble vitamin C. We also make a 14-in-1 Methylated B Complex for Women that adds DIM, an inositol complex and cranberry extract.
A B12-only product is the most focused lane. Our Methyl B12 1,000mcg chewable tablets are one tablet a day, and we also make a 5,000mcg version taken as two tablets daily.
| Product type | Best fit | What to check |
|---|---|---|
| Methylated multivitamin | Broad daily nutrient support | Overlap with other products |
| Methylated B-complex | Active-form B-vitamin focus | Combined B-vitamin totals |
| Methyl B12 | Single-nutrient focus | Dose per tablet and serving |
| L-methylfolate formula | Folate-centered stack | Folate in mcg DFE and mg |
If you don't know which lane you need, start with your diet and your current supplement list. The answer is often already on those labels.

What Quality Markers Should You Check?
Good methylated multivitamin labels are specific. Look for these markers before buying:
- Folate form is named clearly.
- B12 form is named clearly.
- B6 and B2 forms are easy to find.
- Serving size is realistic for daily use.
- Daily Value percentages are visible.
- Mineral forms and amounts are listed.
- Third-party testing is easy to find.
"No fillers" is a nice extra, but it shouldn't be the only reason you buy. A good capsule still needs a readable panel, sensible amounts and named ingredient forms.
Also check overlap. A multivitamin, a B-complex, a methylfolate product and an energy formula can all contain B vitamins, so add the totals across labels before deciding the stack makes sense.
Methylated B vitamins are generally well tolerated in studies at typical amounts. Check with a healthcare professional if you're pregnant, nursing, managing a medical condition or taking medication.
FAQ
Is methylfolate better than folic acid?
Methylfolate is absorbed at least as well as folic acid, so it's a reasonable choice if you prefer the active form. Folic acid is still the form the CDC recommends for anyone who could become pregnant.
Do I need a methylated multivitamin if I have MTHFR?
Not necessarily. The NIH calls the research on folate supplements for people with the common MTHFR variant inconclusive, noting some might benefit from 5-MTHF, so it's a question to settle with your clinician.
Is methylcobalamin better than cyanocobalamin?
Methylcobalamin is one of the two active forms of B12, while cyanocobalamin is converted in the body. The NIH reports no evidence that absorption differs by form, so dose and your reason for taking it matter more.
If you want active-form B vitamins in one daily formula, start with our Methylated Multivitamin and check its panel against anything else you already take. If you only need the B side, our Methylated B Complex keeps the label shorter and easier to track.
