Who this guide is for
If your child needs extra support for the MTHFR gene variant, has trouble converting folic acid, or your pediatrician recommended an active B9/B12 supplement, plain folic acid pills often aren't the right fit. This guide is for parents who searched for kids' methylfolate plus B12 cofactor drops -- especially unflavored ("flavorless") options for picky kids or those with taste sensitivities, alongside a couple of flavored and budget alternatives -- and want real products compared side by side instead of guessing.

The picks, reviewed
1. Organic Kids Methylfolate + Methyl B12 Cofactor, Flavorless
This is the one to reach for if your child rejects anything with a taste -- it's genuinely unflavored, so it disappears into water, juice, or a bottle without a fight. It pairs methylfolate with a methyl B12 cofactor, which is the combination most parents are told to look for when working with MTHFR-related needs.
Pros:
- No added flavor, sweetener, or dye to trigger sensory refusal
- Organic ingredient list
- Sublingual liquid format is easy to dose by drop count
Cons:
- Some kids still notice a faint bitterness without a carrier drink
- Bottle size means frequent reordering for daily use
Who should skip it: kids who need a flavored version to accept any supplement at all -- see the berry pick below instead.
2. Organic Kids L-Methylfolate + Methyl B12 Cofactor, Sublingual (MTHFR Form)
This listing leans specifically into the MTHFR angle, marketing itself around the active, pre-converted folate form that bypasses the enzyme step some kids struggle with. It has the largest review base of the group by a wide margin, which is reassuring for a supplement category where formulation consistency matters.
Pros:
- Large, established review history
- Sublingual delivery for faster absorption
- Marketed specifically for MTHFR-variant support
Cons:
- Not labeled flavorless -- has a mild taste some picky kids notice
- Pricier per bottle than the budget pick
Who should skip it: anyone who wants a completely taste-free option -- go with pick #1.
3. Organic FolinicActive Kids -- Folinic Acid + B12, B6 & B2 Cofactors
If a pediatrician specifically recommended folinic acid rather than methylfolate, or your child does better on a broader cofactor stack, this formula adds B6 and B2 alongside B12 and offers age-adjustable dosing from 1 to 18 years. It carries the highest rating of the group.
Pros:
- Highest average rating in this roundup
- Broader B-vitamin cofactor stack (B6, B2 included)
- Age-adjustable dosing chart for a wide range
Cons:
- Berry flavored, not flavorless
- A different active form (folinic acid) than the methylfolate-specific picks -- confirm which your provider wants
Who should skip it: parents whose provider specifically asked for L-methylfolate rather than folinic acid.
4. JoySpring MethylBee Kids Methylfolate Drops, Berry
For kids who simply won't take anything unflavored, this berry version from JoySpring keeps the same methylfolate-plus-B12 concept but adds a mild fruit taste. It's aimed at ages 3 and up and comes in a smaller 30-serving size, useful for testing whether the formula agrees with your child before committing to a bigger bottle.
Pros:
- Mild berry flavor increases acceptance for picky kids
- Smaller bottle size is a lower-cost way to trial the supplement
- From a brand focused specifically on kids' methylated vitamins
Cons:
- Smaller serving count means more frequent reorders if it works well
- Flavoring won't suit kids who react to any added taste
Who should skip it: kids who need a strictly flavorless, additive-free option -- pick #1 is the better fit.
5. L-Methylfolate 15mg Liquid Drops + Methyl B12 (Budget Pick)
Labeled for both adults and kids, this is the lowest-priced option here and still combines methylfolate with methyl B12 in a liquid drop format. It's a reasonable way to start if you're price-sensitive or just want to see how your child tolerates the combination before buying a premium kids-specific bottle.
Pros:
- Lowest price per bottle in this roundup
- Same core methylfolate + methyl B12 combination as the pricier picks
- Liquid drops are easy to dose down for smaller kids
Cons:
- Not marketed as a dedicated kids formula, so double-check the dosing chart before giving it to a young child
- Fewer reviews than the top two picks
Who should skip it: parents who want a bottle formulated and labeled specifically for children from the outset.
How we chose these picks
We focused on products that explicitly combine methylfolate (or folinic acid) with a B12 cofactor, since that pairing is what most parents searching this topic have been told to look for. We prioritized listings with real review volume and ratings above 4.3 stars, made sure at least one option was genuinely flavorless for sensory-sensitive kids, and included one clearly budget-friendly alternative and one flavored alternative so parents have real choices rather than one-size-fits-all advice. We did not include any product without a verifiable Amazon listing, price, rating, and review count at the time of writing.
Buying guide: what to check before you order
- Flavorless vs. flavored: if your child rejects any taste, don't gamble on a "mild flavor" listing -- choose one explicitly labeled flavorless.
- Methylfolate vs. folinic acid: these are related but not identical active forms. If a provider specified one, match it exactly.
- Dosing by age/weight: liquid drops let you titrate dose more precisely than gummies or capsules -- check the label's drop-to-mcg conversion.
- Third-party kids-specific labeling: products marketed and dosed specifically for children are generally easier to dial in safely than adult formulas repurposed for kids.
- Talk to your pediatrician first: methylfolate and B12 supplementation for a suspected MTHFR variant should be guided by an actual test result and a provider's dosing recommendation, not guesswork.
Final verdict
For most parents dealing with a genuine flavor-refusal problem, the flavorless Organic Kids Methylfolate + Methyl B12 drops (pick #1) is the safest starting point. If your child's needs are specifically framed around MTHFR support and you want a product with a long review track record, the sublingual MTHFR-focused option (pick #2) is the stronger choice. Budget-conscious parents can start with pick #5 to confirm tolerance before upgrading to a dedicated kids formula.
Frequently asked questions
What's the difference between methylfolate and folic acid for kids?
Methylfolate (L-5-MTHF) is the already-active form of folate that the body can use directly, while folic acid needs to be converted through an enzyme step that some people process less efficiently. Providers often recommend methylfolate specifically for kids with a suspected MTHFR gene variant.
Why pair methylfolate with B12?
B12 works alongside folate in the same metabolic pathway (the methylation cycle), so many pediatric formulas combine the two rather than dosing folate alone.
Is a flavorless supplement necessary for every child?
No -- it mainly matters for kids who refuse anything with a noticeable taste. Kids who don't mind a mild berry or fruit flavor may do just as well with a flavored formula, which can also make daily dosing easier for the parent.
Should I start supplementing without a doctor's recommendation?
It's best to have an MTHFR-related supplement recommended and dosed by your child's pediatrician, especially since drop-based dosing varies by product concentration.
Can these drops be mixed into food or a bottle?
Most liquid drop formulas, including the flavorless ones, can be mixed into a small amount of water, juice, or a bottle -- check the specific product label for any temperature or mixing guidance.
