Nutricost leads with 2,000 mcg per capsule plus methyl folate, and 120 caps to a bottle. - Author: Tanner Torres - Tags: Health & Wellness, Health, Supplements The best gluten free methylated vitamin b12 is Nutricost's Methylated Vitamin B12 + Folate at 2,000 mcg per serving across 120 capsules, because it pairs methylcobalamin with methyl folate in one bottle at the lowest price position in this set. If you want all eight B vitamins in a single softgel instead, Sports Research Vitamin B-Complex covers the whole family in 60 Plantgels. Here is the price-band map for this shortlist. The entry tier gets you a straightforward methylated B12 bottle, sometimes paired with methyl folate, in capsule counts of 60 to 240\. The mid tier trades capsules for a 1 fl oz spray with 1,500 mcg per serving, which suits people who cannot swallow pills. The premium tier is where third-party certification and 11-in-1 methylated B complexes with added vitamin C, choline and inositol appear. None of the tiers here is expensive relative to daily supplement use, and the entry tier is not obviously worse: it is just narrower in scope. In this guide 1.

Everything else came second. Three disqualifiers thinned the field. First, any product that named cyanocobalamin rather than methylcobalamin was cut. The whole category is about the methylated form, so calling a cyano B12 a "methylated" pick would misread the keyword. Second, any pick whose listing did not explicitly claim gluten-free was set aside. That matters because Amazon's search for the phrase pulls in adjacent products, and the qualifier is only partially honoured. Every one of the seven picks below states gluten-free in its own listing copy: Nutricost calls it out on both B12 bottles, MaryRuth's spray lists it under "For Most Lifestyles", Sports Research states non-GMO and gluten-free on both softgels, THORNE ships third-party certified, and Micro Ingredients lists gluten among the excluded allergens. Third, I cut anything that was only a plain B-complex with no methylated B12\. The category demands methylcobalamin specifically, and a generic B-complex where B12 is undefined is not the same product. What survived is what you see: five B12-forward picks, two methylated B-complex options, and one non-capsule delivery form for people who cannot take pills. ## 1\. Nutricost Methylated Vitamin B12 + Folate — Best overall **Nutricost's Methylated B12 + Folate is the best gluten free methylated vitamin b12 because it pairs methylcobalamin and methyl folate at 1,000 mcg each in a 120-capsule bottle at the lowest price position in this set.** [![Nutricost Methylated B12 + Folate bottle, front of label — showing the methylcobalamin and methyl folate claim](https://m.media-amazon.com/images/I/416hBeAHI9L._SL500_.jpg)](https://www.amazon.com/dp/B0FNFR1MPT?tag=mundocisco-20) **Best for:** anyone who wants methyl B12 and methyl folate in one capsule **Skip it if:** you already take a full B-complex The reason this one takes the top slot is set composition. Of the seven picks, only two combine methylcobalamin with methyl folate in a single capsule, and this is the cheaper of those two. Nutricost's listing says each serving delivers 1,000 mcg of methylcobalamin, 1,000 mcg of methyl folate as vitamin B9, and adds 30 mg of calcium per serving. The bottle is 120 capsules on the 3.85 x 2.12 x 2.12 in footprint, which is a compact daily-use size. Nutricost states manufacture in an NSF-certified, GMP-compliant, FDA-registered facility and calls the formula gluten-free on the same listing. What it trades away is testing depth. THORNE goes further with third-party certification and Sports Research puts its 5-MTHF pick through third-party testing too. Nutricost names the facility standards but stops there. For most daily users that is a reasonable trade for the price position and the paired methyl folate. If you want the paperwork, look at THORNE next. **Pros:** - Pairs methylcobalamin and methyl folate at 1,000 mcg each - 120 capsules per bottle at the lowest price position here - Gluten-free stated directly on the listing - Adds 30 mg of calcium per serving - Manufactured in an NSF-certified, GMP-compliant facility **Cons:** - No third-party certification named on the listing - Fewer published specifications than THORNE - Not a full B-complex, so pair with other B vitamins if you need them [Check Price on Amazon](https://www.amazon.com/dp/B0FNFR1MPT?tag=mundocisco-20) ## 2\. Sports Research Vitamin B-Complex — Best for families **Sports Research's B-Complex covers all eight B vitamins in a single 60-count Plantgel, which is the simplest way for a whole household to run one bottle instead of three.** [![Sports Research Vitamin B-Complex bottle, 60 Plantgels — showing the all-eight-B claim](https://m.media-amazon.com/images/I/41op+BArFyL._SL500_.jpg)](https://www.amazon.com/dp/B0CVP43YJ4?tag=mundocisco-20) **Best for:** households that want one bottle covering all eight B vitamins **Skip it if:** you need a high single-nutrient B12 dose This is the one for shoppers who do not want to think about individual B vitamins. Sports Research says each veggie softgel contains the full spectrum of all 8 B vitamins, with folate as L-5-methyltetrahydrofolic acid and B6 as pyridoxal 5' phosphate, both active forms. It is one of the top sellers in this set of seven, so demand for a full-spectrum bottle rather than a single-nutrient one is clear. The bottle footprint is 4 x 2 x 2 in and the count is 60. The trade-off is dose specificity. If you already know you need a large single B12 dose because of diet or an absorption issue, a 60-day B-complex is not the tool: you want the 2,000 mcg B12-only bottles further down the list. Sports Research lists the formula as non-GMO with the active folate form named, and the same brand's 5-MTHF pick sits lower in the ranking for a reason: this one is broader. **Pros:** - All 8 B vitamins in one Plantgel - Uses L-5-MTHF and P5P as active forms - Compact 4 x 2 x 2 in bottle for shared storage - Family-owned brand founded in 1980 per the listing - Entry-tier price position for a full B-complex **Cons:** - Only 60 softgels per bottle - B12 dose per gel not stated in the pulled listing copy - Broader ingredient list than a single-nutrient buyer needs [Check Price on Amazon](https://www.amazon.com/dp/B0CVP43YJ4?tag=mundocisco-20) ## 3\. THORNE Vitamin B12 — Most versatile **THORNE's B12 is the most versatile pick here because it delivers 1 mg of methylcobalamin per capsule and its listing states third-party certification, which no other bottle in this set names as clearly.** [![THORNE Vitamin B12 1,000 mcg bottle — showing the methylcobalamin and third-party certified claim](https://m.media-amazon.com/images/I/31NaSoj-iHL._SL500_.jpg)](https://www.amazon.com/dp/B002BKW1YA?tag=mundocisco-20) **Best for:** shoppers who want a third-party-tested single-ingredient B12 **Skip it if:** you want the lowest price position in the set THORNE lists 1 mg of vitamin B12 as methylcobalamin per capsule, 60 capsules per bottle, weight 1.12 oz, and a 3.22 x 1.83 x 1.83 in footprint. The claim buyers care about most sits under Third-Party Certified: THORNE says the product has been third-party tested and certified to verify what is in the package matches the label. THORNE's listing also names uses well beyond the standard energy-and-nerve pitch, including homocysteine support and circadian rhythm support for sleep. This is the most expensive pick in the set, and the highest single-nutrient B12 price position. What you buy for that is documentation. If you take supplements because a clinician told you to and you want the paperwork to back the label, THORNE is the one. The loss against the winner is that you do not get methyl folate in the same capsule, so if methylation across folate and B12 is the goal, the Nutricost combo or the Sports Research 5-MTHF pick match the brief more directly. **Pros:** - Methylcobalamin at 1 mg per capsule stated on the listing - Third-party tested and certified per the listing - Compact bottle at 1.12 oz total - Listing names sleep and homocysteine support uses **Cons:** - Highest price position in the set - 60 capsules only, so runs out fastest of the B12 bottles - No folate included [Check Price on Amazon](https://www.amazon.com/dp/B002BKW1YA?tag=mundocisco-20) ## 4\. Nutricost Vitamin B12 2000mcg — Best upgrade **Nutricost's 2,000 mcg methylcobalamin bottle stretches to 240 capsules, which is the longest single-bottle supply in this set.** [![Nutricost Vitamin B12 2000mcg bottle, 240 capsules — showing the methylcobalamin dose and count](https://m.media-amazon.com/images/I/41l7QiB7wML._SL500_.jpg)](https://www.amazon.com/dp/B01IQB2UYS?tag=mundocisco-20) **Best for:** daily users who want the longest single-bottle supply **Skip it if:** you also need folate in the same capsule Here is where set composition helps you again. Only two picks come in 240-count bottles: this one and the Micro Ingredients B complex. This is the cheaper of the pair, and it uses the higher single-nutrient B12 dose of 2,000 mcg methylcobalamin per capsule. The listing weighs the bottle at 5.93 oz. Nutricost states testing by independent, ISO-accredited third-party laboratories and calls out non-GMO, vegetarian-friendly and gluten-free. Skip it if you want folate paired with your B12: this bottle is B12 only, and it is the sibling of the winner rather than a competitor. Think of the two Nutricost bottles as a decision about scope. If you are new to methylated supplementation and want the combo, pick the winner. If you know you only want B12 and you want it in bulk, pick this. The other loss is the missing dimension figure on the listing, so cabinet fit is a guess unless you check when the bottle arrives. **Pros:** - 240 capsules per bottle, longest single supply here - 2,000 mcg methylcobalamin per capsule - Third-party tested per the listing - Gluten-free and non-GMO stated on the listing - Entry-tier price position **Cons:** - No folate included - Bottle dimensions not listed - Fewer stated uses on the listing than THORNE [Check Price on Amazon](https://www.amazon.com/dp/B01IQB2UYS?tag=mundocisco-20) ## 5\. MaryRuth's Organic Methyl B12 Spray — Best minimal setup **MaryRuth's is the only spray in this set, and it delivers 1,500 mcg of methyl B12 per serving from a 1 fl oz bottle for people who cannot swallow capsules.** [![MaryRuth's Organic Methyl B12 Spray, 1 fl oz bottle — showing the spray delivery format](https://m.media-amazon.com/images/I/51hQtWeuZdL._SL500_.jpg)](https://www.amazon.com/dp/B0785G192Q?tag=mundocisco-20) **Best for:** people who dislike swallowing capsules **Skip it if:** you want a 90-day supply from one bottle Every other pick is a capsule or a softgel. MaryRuth's is a 1 fl oz berry-flavoured spray at 1,500 mcg B12 per serving, and the listing calls it USDA Organic, Vegan, Non-GMO, Dairy Free, Nut Free, Gluten Free, Sugar Free, and Clean Label Project Certified. The bottle measures 5 x 2 x 1 in and weighs 1.44 oz. The listing explicitly frames it against pills: "No more hard-to-swallow pills or capsules". The trade-off is longevity. A 1 fl oz bottle does not stretch the way 240 capsules stretches, and the listing does not put an exact number of servings on the label copy. If you already tolerate capsules well, the two 240-count bottles above give you far more mileage. What the spray earns is the ability to work at all for the people who have gagged their way through pills for years, and the certifications it stacks on the label are the deepest of any pick here. **Pros:** - Only spray delivery in the set - 1,500 mcg methyl B12 per serving - USDA Organic and Clean Label Project Certified per the listing - Berry flavour, portable 5 x 2 x 1 in bottle - Stacks vegan, non-GMO, dairy-free and sugar-free claims **Cons:** - Small 1 fl oz volume - Servings per bottle not stated on the pulled listing copy - Mid-tier price position for less nutrient volume than capsules [Check Price on Amazon](https://www.amazon.com/dp/B0785G192Q?tag=mundocisco-20) ## 6\. Sports Research 5-MTHF Methyl Folate w/Methylated B12 — Best for pros **Sports Research's 5-MTHF pick is the methylation specialist here, pairing 1,000 mcg DFE L-methylfolate with 2,000 mcg methylcobalamin per Plantgel.** [![Sports Research 5-MTHF Methyl Folate with Methylated B12 bottle, 90 Plantgels — showing the paired methylation claim](https://m.media-amazon.com/images/I/41N-zWwUQuL._SL500_.jpg)](https://www.amazon.com/dp/B0GQXDQHQH?tag=mundocisco-20) **Best for:** shoppers focused on methylation with both 5-MTHF and B12 **Skip it if:** you only need B12 on its own This is the second methyl-folate-plus-methyl-B12 combo in the set, and the doses run higher than the winner: 1,000 mcg DFE 5-MTHF plus 2,000 mcg methylcobalamin per Plantgel across 90 softgels. The listing frames 5-MTHF as the active form of folic acid and states the formula includes coconut-derived MCT oil to support absorption in a veggie softgel. Sports Research lists it as certified non-GMO and free from gluten, dairy and soy, with third-party testing. The reason this sits below the Nutricost combo rather than above it comes down to price position and pick order intent. This one is in the premium tier and Nutricost is entry, and both deliver the same paired methylation logic. For someone who wants the higher doses, MCT oil delivery and third-party testing, this is the upgrade. The loss is exactly what you would expect at premium: the price position rises, and if you only came for B12, you are paying for folate you may not need. **Pros:** - 2,000 mcg methylcobalamin plus 1,000 mcg DFE 5-MTHF per gel - Veggie softgel with coconut MCT oil for absorption per the listing - Third-party tested, certified non-GMO - Free from gluten, dairy and soy per the listing - 90 softgels per bottle **Cons:** - Premium price position - Overkill if you only need B12 - Softgel size not stated on the pulled listing [Check Price on Amazon](https://www.amazon.com/dp/B0GQXDQHQH?tag=mundocisco-20) ## 7\. Micro Ingredients Pure Methylated B Complex Vitamins — Best premium **Micro Ingredients' methylated B complex is the widest formula in the set, an 11-in-1 that adds vitamin C, choline and inositol to the eight methylated B vitamins.** [![Micro Ingredients Pure Methylated B Complex bottle, 240 capsules — showing the 11-in-1 formula claim](https://m.media-amazon.com/images/I/41i8cSv0DbL._SL500_.jpg)](https://www.amazon.com/dp/B0DLLHRVLY?tag=mundocisco-20) **Best for:** buyers who want an 11-in-1 methylated B complex with vitamin C **Skip it if:** you want a short, targeted ingredient list Micro Ingredients calls this an 11-in-1 formula: vitamin C as ascorbyl palmitate and ascorbic acid, thiamin, riboflavin as R5P, niacin as niacinamide, B6 as P5P, folate, methylated B12, plus choline and inositol. The count is 240 capsules per bottle, tied with the Nutricost 2000 mcg pick for the largest supply here. The listing states the formula is non-GMO and made without fillers, soy, dairy, gluten, fish, shellfish, peanuts and tree nuts, which is the broadest allergen exclusion list of any pick. Skip it if you already take vitamin C separately or if you prefer a short ingredient panel. This is the highest price position in the whole set for a reason: you are paying for the widest formula, not the deepest single-nutrient dose. Against the Sports Research B-Complex, Micro Ingredients adds vitamin C and the choline-inositol pair, and doubles the capsule count. Against the winner, it dilutes the B12-and-folate focus into a wider mix. **Pros:** - 11-in-1 methylated B complex with vitamin C - 240 capsules per bottle, tied for longest supply here - Uses R5P, P5P and methylated folate per the listing - Excludes gluten, soy, dairy, fish, shellfish, peanuts and tree nuts - Adds choline and inositol to the B complex **Cons:** - Highest price position among the B complexes - Ingredient list may be broader than a targeted buyer wants - Bottle dimensions not stated on the listing [Check Price on Amazon](https://www.amazon.com/dp/B0DLLHRVLY?tag=mundocisco-20) ## Methylcobalamin, methyl folate, and why the label wording matters The label wording is the whole game with this category. A "methylated" vitamin B12 supplement means the B12 is delivered as methylcobalamin, not cyanocobalamin. Methylcobalamin is the active form named on the label of every pick above. THORNE's listing says methylcobalamin is "more efficiently used by the body compared to other forms of vitamin B12, like cyanocobalamin". That is the manufacturer's framing, not a measured claim, but it is why the category exists. Methyl folate is the other half of the methylation story, and it is where the winner earns its place. Folate on a supplement label can appear three ways: - **Folic acid**, the synthetic form. - **Folate**, sometimes generic and sometimes methylated. - **L-5-methyltetrahydrofolate**, also written as 5-MTHF or L-methylfolate, the active methylated form. The two picks that pair methylcobalamin with 5-MTHF are Nutricost's Methylated B12 + Folate and Sports Research's 5-MTHF with Methylated B12\. Sports Research's B-Complex names L-5-methyltetrahydrofolic acid too, and Micro Ingredients names methylated folate in its 11-in-1\. If you have been told to take methylated folate alongside B12, those are the four picks to weigh against each other. The three B12-only bottles will not fill the folate half of that request. ## Capsule, softgel or spray: which delivery suits you? Delivery format is often the deciding factor for the reader who has already picked the ingredient. Three shapes are on offer here. 1. **Capsules.** Nutricost's two bottles, THORNE's B12, and Micro Ingredients' 11-in-1 are all capsules. These are the plain, unflavoured, water-swallow format. They stack well in a pillbox and travel without leaking. 2. **Plantgels or veggie softgels.** Sports Research uses these for both its B-Complex and its 5-MTHF pick. The listings say the softgels are veggie and, for the 5-MTHF pick, formulated with coconut MCT oil. 3. **Spray.** MaryRuth's is the only spray, at 1,500 mcg per serving from a 1 fl oz bottle. If you have a swallowing issue, only MaryRuth's solves it directly. If you tolerate capsules well but dislike the feel of gelatin softgels, the four capsule picks are the way. If you are indifferent to format and want the highest single-nutrient B12 dose, the two 2,000 mcg picks are Nutricost's 240-count bottle and Sports Research's 5-MTHF softgel. ## How long does one bottle actually last? This category confuses buyers because the mcg number on the front of the bottle and the number of days a bottle lasts are two different things. Serving size, not per-capsule dose, decides longevity. Here is what the listings actually state. - Nutricost Methylated B12 + Folate: 120 capsules per bottle. - Nutricost Vitamin B12 2000mcg: 240 capsules per bottle. - THORNE Vitamin B12: 60 capsules per bottle. - Sports Research Vitamin B-Complex: 60 Plantgels per bottle. - Sports Research 5-MTHF with Methyl B12: 90 Plantgels per bottle. - Micro Ingredients Pure Methylated B Complex: 240 capsules per bottle. - MaryRuth's Methyl B12 Spray: 1 fl oz bottle. At one capsule a day, the two 240-count bottles run about eight months, the 120-count winner runs four, the 90-count Sports Research 5-MTHF runs three, and the two 60-count bottles run two. The spray does not publish a per-bottle serving count in the pulled listing copy, so plan a re-order sooner than for the capsules. If you dose more than once a day, halve those numbers. ## What the listings do not tell you about gluten claims The keyword here is only partially supported by Amazon's search, and the reason matters. A supplement listing that says "gluten free" in the feature bullets is stating the manufacturer's claim. It is not a certification unless the listing also names one. Read what is on each product's page carefully. Of these seven picks, Nutricost states gluten-free on both bottles and names an NSF-certified, GMP-compliant, FDA-registered facility. MaryRuth's names Clean Label Project Certified and lists gluten-free among a longer allergen exclusion list. Sports Research names non-GMO and gluten-free on both softgel bottles. THORNE names third-party testing and certification without singling out gluten in the pulled copy, so check the on-page label. Micro Ingredients names gluten among the allergens it excludes, alongside soy, dairy and shellfish. If you have celiac disease rather than a preference, the strongest paper trail belongs to MaryRuth's Clean Label Project certification and Nutricost's NSF-certified facility. The others are manufacturer claims. That does not make them wrong. It means the reader has to judge, because the listing does not offer more than the wording it prints. Contact the brand if a bottle's certification status is not obvious on the page. ## The verdict Nutricost's Methylated Vitamin B12 + Folate is the right default for the best gluten free methylated vitamin b12\. It pairs 1,000 mcg of methylcobalamin with 1,000 mcg of methyl folate in a single 120-capsule bottle at the lowest price position in the set, and its listing states manufacture in an NSF-certified, GMP-compliant, FDA-registered facility. Two conditions flip that answer. If you want the whole B family covered in one softgel for a shared household, Sports Research Vitamin B-Complex is the better buy: it names all eight B vitamins with the active folate and P5P forms in 60 Plantgels. The cutoff is scope. Below one nutrient goal, Nutricost's pair wins. Above the B12 line, the B-Complex wins because you would otherwise buy two bottles. The second flip is documentation. If you take supplements on a clinician's advice and you want third-party certification named on the listing, THORNE's Vitamin B12 is the right pick, even at the highest price position here, because it is the only single-nutrient B12 bottle that names third-party testing and certification directly. If you cannot swallow capsules at all, MaryRuth's spray is the only pick that solves that. ## FAQ ### Is methylated B12 better than regular B12? Methylated B12 refers to methylcobalamin, the active form named on every bottle in this roundup. THORNE's listing says methylcobalamin is "more efficiently used by the body compared to other forms of vitamin B12, like cyanocobalamin". That is a manufacturer claim rather than a measured result, but it is why buyers seeking a methylated B12 want the label to name methylcobalamin specifically instead of cyanocobalamin or an unspecified form. ### Is a gluten free methylated vitamin b12 worth paying more for? A gluten free methylated vitamin b12 is worth the price position in this set for two shopper profiles: people with celiac disease or a diagnosed gluten sensitivity, and people who want the active methylcobalamin form regardless of gluten. For everyone else, the entry-tier picks like the two Nutricost bottles already state gluten-free and use methylcobalamin, so the extra premium buys documentation or a wider formula, not a stronger core ingredient. ### What is the difference between methyl B12 and methyl folate? The difference between methyl B12 and methyl folate is the underlying vitamin. Methyl B12 is vitamin B12 as methylcobalamin. Methyl folate is vitamin B9 as L-5-methyltetrahydrofolate, sometimes written 5-MTHF. They are two separate nutrients that both matter for methylation. The Nutricost winner and the Sports Research 5-MTHF pick bundle both into one capsule, while the THORNE and Nutricost 2,000 mcg bottles deliver B12 only. ### Should I pick Nutricost's combo or THORNE for a B12 supplement? Should I pick Nutricost's combo or THORNE depends on what else you take. Nutricost's Methylated B12 + Folate pairs 1,000 mcg methylcobalamin with 1,000 mcg methyl folate in 120 capsules at the entry tier, so it is the better single-bottle answer if you want both. THORNE delivers 1 mg of methylcobalamin per capsule in 60 capsules with third-party testing and certification named on the listing, which is the better answer if documentation matters and you take folate elsewhere. ### What is the biggest mistake people make buying methylated B12? The biggest mistake is confusing "B-complex" with "methylated B12" and buying a generic B-complex where the B12 form is not stated. Read the label for the exact word methylcobalamin. Sports Research's B-Complex names it in the full-spectrum bullet, Micro Ingredients names methylated B12 in its 11-in-1, and every B12-only bottle above names methylcobalamin. Anything vaguer than that is not the product this category describes. Ready to pick? Start with Nutricost's Methylated B12 + Folate if you want the direct answer to the keyword and a four-month supply from a single 120-capsule bottle at the lowest price position in the set. Move to Sports Research's B-Complex if the household needs all eight B vitamins in one Plantgel, and to THORNE's B12 if third-party certification is the thing that decides your shortlist. If capsules are the barrier, MaryRuth's spray is the only pick that removes it. Whatever you choose, the label word to check first is methylcobalamin. *Last updated: September 24, 2026\.
