Product details
Verbiva Kids Folinic Acid Drops give your child folinic acid – an already-active form of folate – together with the B-vitamins it works with: vitamin B12 in three active forms (methylcobalamin, adenosylcobalamin and hydroxocobalamin), vitamin B6 as P-5-P and vitamin B2 as R-5-P.
Lightly berry-flavored drops in a glycerin base, dosed by age from 1 to 18. 60 mL glass bottle with dropper.
Benefits
- Supports verbal communication and language development†
- Supports healthy brain development†
- Encourages calm and emotional balance†
- Supports focus and attention†
- Folinic acid can use the reduced folate carrier – a route that doesn’t depend on folate receptor alpha

How to use
Shake well. Count drops with the dropper, once a day:
- Ages 1–3: 10 drops
- Ages 4–13: 20 drops
- Ages 14–18: 30 drops
Give straight or mixed into water, juice or milk. Refrigerate after opening. One bottle is a 30-day supply at every age – younger children use fewer drops, so it often lasts longer.
Talk to your child’s doctor before starting any supplement, especially if your child takes medication.

Why this formula works
Built differently, for a reason.
Four decisions behind every bottle – made for children whose folate needs to take a different route.
1Folinic acid, not folic acid
Most kids’ vitamins use folic acid, which the body has to convert first. Folinic acid is already active – the same molecule as prescription leucovorin – and it can use a second route into cells, the reduced folate carrier, that doesn’t depend on folate receptor alpha. Same destination, different road.
2Dosed by age, toddler to teen
Kids don’t all need the same amount. Ages 1–3 take 10 drops, ages 4–13 take 20 and teens take 30 – counted with the dropper, once a day. No pills to swallow, no guessing, one bottle for the whole family.
3The complete cofactor chain
Folate never works alone. It needs B12 for the methylation cycle, B6 to build neurotransmitters and B2 to keep the whole chain turning. So we add all three in their active forms: methyl-, adenosyl- and hydroxocobalamin, P-5-P and R-5-P.
4Third-party lab tested
Every batch goes to an independent lab before it ships – checked for heavy metals, microbes, potency and identity – because this is something you give your child every single day. USDA Organic, vegan, gluten-free, non-GMO. Nothing hidden.

""I cannot believe the difference in my son in 10 weeks. He went from zero words to saying mama and more at the dinner table. I have tried everything for three years. Nothing moved the needle until Verbiva.""
""As a speech-language pathologist I was skeptical. But after seeing the research on FRAAs and watching two of my patients on Verbiva make gains I could not explain otherwise — I now recommend it to every autism parent I work with.""
""My daughter had been nonverbal for four years. Her therapist pulled me aside after week 11 and asked what had changed. She had no idea we started Verbiva. That moment said everything.""
""We spent over $4,000 on supplements that did nothing. Verbiva is the first thing we have tried that gave us a biological reason why everything else failed — and then actually worked. Week 8 my son said hi to his therapist unprompted. First word in two years.""
The science
The science, in plain words.
Your child deserves more than empty promises. Verbiva Folinic Acid Drops give the form of folate that can take a second route into the brain – with the B-vitamins it works with. Here’s what the research behind it found.
Folate reaches the brain through one main door
Folate is carried into the brain by folate receptor alpha. In some children, the immune system makes autoantibodies that block it – so blood folate can look normal while the brain gets too little.
A 2021 meta-analysis estimated these autoantibodies in about 71% of autistic children tested.
“Children with ASD were 19.03-fold more likely to be positive for a FRAA compared to typically developing children without an ASD sibling.”

2005: a blocked door – and a way around it
Pediatric neurologists at University Hospital Aachen found blocking autoantibodies in 25 of 28 children with cerebral folate deficiency – and in none of 28 healthy controls.
“Oral folinic acid normalized 5MTHF levels in the cerebrospinal fluid and led to clinical improvement.”

A placebo-controlled trial in 48 children
Children with autism and language impairment took folinic acid or a placebo for 12 weeks at Arkansas Children’s Hospital. Those on folinic acid improved more in verbal communication. The authors called it a small trial and asked for larger studies.
“There was no significant difference in adverse effects between treatment groups.”
Frye et al. · Molecular Psychiatry, 2018 · randomized, double-blind, placebo-controlled· Read the study ↗
An honest word about dose
The 2018 trial used prescription-strength folinic acid (leucovorin): 2 mg per kg of body weight a day, up to 50 mg, under a doctor’s care. Verbiva is a daily nutritional dose – 170 to 510 mcg DFE of folate as folinic acid, by age – with active B12, B6 and B2.
No over-the-counter drop matches the trial dose, and we won’t pretend otherwise. If you’re considering high-dose folinic acid, talk to your child’s doctor.

Autoantibodies to folate receptors in the cerebral folate deficiency syndrome
Vincent T. Ramaekers, Sheldon P. Rothenberg, Jeffrey M. Sequeira, Thomas Opladen, Nenad Blau, Edward V. Quadros, Jacob Selhub
Division of Pediatric Neurology, University Hospital Aachen, Germany
Some children have plenty of folate in their blood, yet almost none of it reaches the brain. This study found out why.
25 of 28children with low brain folate carried antibodies that block the folate receptor
0 of 28healthy children of the same age had them
Back to normalbrain-fluid folate after folinic acid by mouth
Key points
- Children with cerebral folate deficiency had normal folate in their blood but very little in the fluid around the brain.
- 25 of 28 of them carried antibodies that block the folate receptor, the main doorway folate uses to reach the brain.
- None of the 28 healthy children had these antibodies.
- Folinic acid by mouth brought brain-fluid folate back to normal, and the children improved.
Background
Folate is a B vitamin the brain needs to grow, build connections and make its chemical messengers. It reaches the brain through a doorway called the folate receptor alpha, which sits in the choroid plexus, the tissue that makes the fluid around the brain and spinal cord.
Doctors had already described a puzzling condition called cerebral folate deficiency. Blood tests showed normal folate, yet the fluid around the brain held very little of it. Nobody knew what was blocking the way.
How the study worked
The team tested blood samples from four groups:
- 28 children with cerebral folate deficiency
- 5 of their mothers
- 28 healthy children of the same age
- 41 patients with an unrelated neurological condition
They looked for antibodies that latch onto the folate receptor and stop folate from binding to it. The children with the condition were treated with folinic acid by mouth, and folate in the fluid around the brain was measured again.
What they found
25 of the 28 children with cerebral folate deficiency had high-affinity antibodies that block the folate receptor. None of the 28 healthy children had them.
After the children took folinic acid by mouth, folate in the fluid around the brain returned to normal and their symptoms improved.
What it means
This was the first study to show why folate can be missing in the brain while blood tests look fine: the body's own antibodies can block the doorway. It also showed that folinic acid can still get folate where it needs to go.
Later research found the same antibodies in many autistic children. That is why the folinic acid story starts with this paper.
Good to know
This was a small study of children with a specific diagnosed condition, not a study of autism itself. The folinic acid was prescribed and given under medical care. The paper explained the mechanism; the autism studies came later.

Cerebral folate receptor autoantibodies in autism spectrum disorder
Richard E. Frye, Jeffrey M. Sequeira, Edward V. Quadros, S. Jill James, Daniel A. Rossignol
Arkansas Children's Hospital Research Institute, University of Arkansas for Medical Sciences, Little Rock, USA
After the 2005 discovery, researchers asked the next question: how common are these antibodies in autism, and do children who have them respond to folinic acid?
75%of 93 autistic children had at least one folate receptor antibody
44antibody-positive children were treated with folinic acid
1 in 3treated children improved moderately to a lot
Key points
- Three in four autistic children tested positive for at least one type of folate receptor antibody.
- In children who had a spinal fluid test, more blocking antibody meant less folate around the brain.
- Over about 4 months, treated children improved more than children still waiting for treatment in verbal communication, language, attention and repetitive behavior.
- Side effects were uncommon.
Background
The 2005 discovery showed that antibodies can stop folate from reaching the brain. Doctors had also noticed autism-like symptoms in some children with cerebral folate deficiency, and reports of improvement with folinic acid. But nobody had checked how common the antibodies are in autism, or how antibody-positive children respond to treatment.
How the study worked
93 children with autism (84 boys and 9 girls, average age about 7) had a blood test for two kinds of folate receptor antibodies: blocking antibodies, which stop folate from attaching to the receptor, and binding antibodies, which stick to it.
16 children also had a spinal fluid test to measure folate around the brain.
44 antibody-positive children were treated with folinic acid (2 mg per kg of body weight per day, up to 50 mg, in two doses). 26 antibody-positive children who were still waiting for test results formed the comparison group. Parents rated changes over an average of about 4 months.
What they found
- 60% had the blocking antibody, 44% the binding antibody and 75% at least one of them.
- In all 16 children with a spinal fluid test, folate around the brain was below the normal average, and the more blocking antibody a child had, the lower it was.
- Treated children improved significantly more than the waiting group in verbal communication, understanding language, speaking, attention and repetitive behavior.
- About two in three treated children showed some improvement in these areas, and about one in three improved moderately to a lot.
- Side effects were uncommon.
What it means
The antibodies are not rare in autism. They are common. And children who have them can respond to folinic acid, especially in language and communication. This study set the stage for the placebo-controlled trial that followed.
Good to know
This was not a blinded trial. Parents knew whether their child was treated, the comparison group did not get a placebo, and the results were based on parent ratings. The children came from specialist clinics, so they may not represent every autistic child. The authors called for double-blind, placebo-controlled studies, which came next.

The gold-standard test. Half the children got folinic acid, half got a look-alike placebo, and nobody, not the families and not the researchers, knew who got which.
48children with autism and language delay, ages 3 to 13
12 weeksdouble-blind, against placebo
+5.7 pointsmore gain in verbal communication than on placebo
Key points
- 48 children with autism and language delay were randomly given folinic acid or an identical-looking placebo for 12 weeks.
- Verbal communication improved significantly more with folinic acid, a medium-to-large effect.
- Children with folate receptor antibodies improved the most.
- Side effects were no different from placebo, and no child on folinic acid had a serious side effect.
Background
Earlier studies looked promising, but parents and doctors knew who was being treated, and in autism research hope alone can make results look better than they are. To find out whether folinic acid really helps, the team ran a randomized, double-blind, placebo-controlled trial, the strongest kind of study in medicine.
How the study worked
- Who: 48 children aged 3 to 13 with autism and language impairment (average age 7 years 4 months; 82% boys), at Arkansas Children's Research Institute, 2012–2013.
- How: each child was randomly assigned to folinic acid (23 children) or placebo (25 children). The capsules looked and felt identical; in a test, nobody could tell them apart.
- Dose: 2 mg per kg of body weight per day, up to 50 mg, in two doses, with half the dose for the first 2 weeks.
- Measured: verbal communication with standard language tests given by trained examiners, plus behavior, daily living skills and autism symptom questionnaires. Every child was also tested for folate receptor antibodies.
What they found
- Verbal communication improved significantly more on folinic acid than on placebo: 5.7 standard points more, a medium-to-large effect.
- In children with folate receptor antibodies, the difference was 7.3 points, a large effect. In children without the antibodies there was no clear difference.
- Significantly more children on folinic acid counted as responders.
- Folinic acid also did better than placebo on irritability, hyperactivity, repetitive behavior, daily living skills and several other behavior scores.
- Side effects were no different between the groups. No child on folinic acid had a serious side effect.
What it means
This is the strongest evidence so far that folinic acid can help language in autistic children: measured by trained examiners, against placebo. It also suggests the folate receptor antibody test can help predict which children are most likely to respond.
Good to know
The trial was small (48 children), ran at one center and lasted 12 weeks. The authors call the results preliminary until larger, longer studies at several centers confirm them; such trials were underway by 2021. The children took prescription folinic acid at a high dose under medical supervision.

Cerebral folate deficiency, folate receptor autoantibodies and leucovorin in autism
Daniel A. Rossignol, Richard E. Frye
Rossignol Medical Center, Aliso Viejo, California; Barrow Neurological Institute at Phoenix Children's Hospital, Arizona, USA
Twenty years of research, pooled together: how common the antibodies are in autism, and what 21 treatment studies found.
71%of autistic children had folate receptor antibodies
19×more often than typically developing children
21treatment studies reviewed, 4 of them placebo-controlled
Key points
- Across studies, 71% of autistic children had folate receptor alpha antibodies, about 19 times more often than typically developing children.
- About 38% of autistic children who had a spinal fluid test showed low brain folate.
- Folinic acid improved communication with medium-to-large effects in the treatment studies.
- Side effects were generally mild, and in placebo-controlled studies no more common than on placebo.
Background
By 2021 there were dozens of studies on folate receptor antibodies and folinic acid in autism: some small, some controlled, some single case reports. A systematic review gathers every relevant study using fixed rules. A meta-analysis then combines their numbers to give a clearer overall picture than any single study can.
How the study worked
The authors searched six research databases, including PubMed, Embase and Scopus, for every study up to September 2021 that measured folate receptor antibodies in autism or treated autistic children with folinic acid (leucovorin).
They pooled the results on how often the antibodies and low brain folate occur, and reviewed 21 treatment studies: four placebo-controlled, three prospective controlled, and the rest open-label studies and case reports.
What they found
- 71% of autistic children had folate receptor alpha antibodies, with little variation between studies.
- Autistic children were about 19 times more likely to have them than typically developing children without an autistic sibling.
- About 38% of autistic children with a spinal fluid test had low brain folate; in 83% of those cases the antibodies were the cause.
- In children with autism and low brain folate, folinic acid was linked to improvement in overall autism symptoms (67%), irritability (58%), coordination (88%) and seizures (75%).
- Across the treatment studies, folinic acid significantly improved communication with medium-to-large effects and helped attention and repetitive behavior.
What it means
The review concludes that folinic acid is an evidence-based treatment for autism with significant promise, that it appears safe and well tolerated, and that the antibodies may help identify the children most likely to benefit. Some children respond quickly, but the biggest gains can take one to two years.
Good to know
Only a few of the studies were blinded and placebo-controlled, and several combined folinic acid with other supplements. The most common side effects reported were agitation (about 12%), aggression (about 10%), trouble sleeping (about 9%), more tantrums (about 6%) and headache (about 5%); in the placebo-controlled studies they were no more common than on placebo. Most studies used 0.5 to 2.5 mg per kg per day of prescription folinic acid.

What Our Customers Are saying...
Great Results
"My son hadn't said a word in over two years. Week 9 on Verbiva he walked into the kitchen and said mama. I stood there and didn't move for a full minute. I have never in my life been so grateful for a supplement."
Huge Difference!
"I was skeptical. I have tried every B vitamin on the market for three years. What made me try Verbiva was the mechanism — folinic acid bypassing the receptors made biological sense in a way nothing else ever had. Week 11 his speech therapist noticed without me saying anything. That was all I needed."
Worth Every Penny
"My daughter was nonverbal for four years. Her therapist told me to focus on AAC. Eight weeks into Verbiva she said her sister's name. Her sister cried. I cried. The therapist asked what changed. Nothing changed except one supplement."
Finally A Solution!!
"Sleep improved first. Then eye contact. Then new sounds. Then words. That was the exact order every parent in the research thread described and it was the exact order it happened for my son. Week 10 he said more at dinner and pointed at his plate. I gave him more and went to the bathroom and cried."
The bottle is easy to store, and the dropper fits neatly back into the cap. It sits in our kitchen cupboard with everything else and nothing ever leaks. We have been using it every morning for a few weeks now and it has become part of our routine without any fuss.
I found the product details quickly and appreciated the clear ingredient list. As a parent I like knowing exactly what is in the bottle, and there were no surprises. Ordering was simple and it arrived within a few days.
A straightforward bottle design that fits easily on our kitchen shelf. The dropper is simple to use, my little one takes it without any trouble, and the packaging felt well made. We have already ordered another pack.
The ordering options were easy to compare before choosing a pack. I went with the larger bundle because it worked out better value, and checkout took a couple of minutes. Everything arrived neatly packed.
The instructions are clearly laid out, which makes the packaging easy to understand. I never have to wonder how much to give, and the label is easy to read even when I am in a rush in the morning.
The small bottle is convenient to keep with our other daily essentials. It is light enough to take on trips, and the cap closes securely so I do not worry about it in the bag. Very happy with it so far.
I liked being able to check the bottle size and ingredients on the same page. It made the decision easy, and when the order arrived everything matched what the page described. Great experience from start to finish.
The dropper feels simple to handle, and the cap closes securely. It is easy to measure out each day and there is no mess. Shipping was quick and the bottle was well protected inside the box.
The page made the available pack sizes and shipping information easy to find. I knew exactly what I would pay and when it would arrive, and it showed up on the day they said. Would happily order again.
The bottle arrived in tidy packaging and was easy to open. Everything inside was neat and secure, the instructions were clear, and the whole thing felt thoughtful. Easy to recommend to other parents.
A compact format that does not take up much space in the cupboard. It fits right next to our other bottles, is easy to grab each day, and we have not missed a day since it arrived. Really pleased.
The product page is clear, with useful information grouped into readable sections. I could find answers to my questions without searching around, and the product itself has been just as easy to live with.

Still deciding?
Ask us anything about Verbiva, dosing or your order. We read every message.
Contact usWhat is folinic acid?
Folinic acid (also called calcium folinate or leucovorin) is a reduced, active form of folate – vitamin B9. Unlike folic acid, it doesn’t need to be converted before the body can use it.
Is Verbiva the same as leucovorin from the doctor?
It’s the same molecule, but not the same dose. Prescription leucovorin is used at much higher doses under medical supervision. Verbiva is a daily nutritional dose with active B12, B6 and B2. If you’re considering high-dose folinic acid, talk to your child’s doctor.
How much do I give?
Ages 1–3: 10 drops. Ages 4–13: 20 drops. Ages 14–18: 30 drops. Once a day, straight or mixed into a drink.
How long does one bottle last?
Plan on one bottle per month – that’s how our bundles are counted (30, 60, 120 or 180 days). Younger children use fewer drops, so a bottle often lasts longer.
Will my child notice the taste?
The drops are lightly berry-flavored in a glycerin base. Most parents mix them into a little juice or water.
When will we see a difference?
Every child is different and nobody can promise a result. Folate status builds over weeks, so give it a consistent 12 weeks and keep a short journal. If it isn’t right for you, the 90-day guarantee applies.
Can my child take it with other supplements or medication?
Please check with your child’s doctor or pharmacist first – especially with seizure medication or any prescription – and tell them about other folate or B-vitamin supplements.
Is Verbiva tested?
Yes. Verbiva is USDA Organic certified, made in a GMP facility, and every batch is third-party tested, including for heavy metals. It is vegan, gluten-free, soy-free and non-GMO.
What’s in it?
Folinic acid (from calcium folinate), vitamin B12 (methylcobalamin, adenosylcobalamin, hydroxocobalamin), vitamin B6 (P-5-P), riboflavin (R-5-P), organic vegetable glycerin, reverse osmosis water and organic berry flavor (organic acacia gum, natural flavors, citric acid).
