The Best Multivitamins for Children with Autism
Multivitamins can be a helpful tool to fill in nutritional gaps, especially for selective eaters. There’s no one-size-fits-all recommendation because each child has their own unique nutrient needs, food sensory preferences, and may have a variety of dietary restrictions due to allergies, sensitivities, or health concerns.
It’s important to recognize that expanding the diet of a selective eater can take time and isn’t something that happens overnight. The process is typically gradual and requires a thoughtful, sensory-friendly approach like food sensory profiling and food chaining. Because of this, having a high quality multivitamin on board early can help replete key nutrients while you work on building variety in a way that feels supportive and realistic for your child.
This is why I always say “you can’t out-supplement diet”. Meaning, a multivitamin isn’t meant to replace food or “fix” everything. The goal is still to build a nourishing, balanced diet over time. A multivitamin should be a support used alongside diet to help fill in gaps while you continue making progress with your child’s eating.
Who Should Take Multivitamins?
Children who…
Are selective eaters (consume fewer than 20 foods on average)
Avoid complete food groups (vegetables, protein, fruit, etc)
Exclude entire food texture groups (soft, crunchy, chewy, etc)
Children following restricted diets (gluten-free, dairy-free, GAPS, plant-based, to name a few)
Children with known gastrointestinal issues
Children who test positive for one or both MTHFR mutations
Children with known nutrient deficiencies
6 Things you should look for in a multivitamin:
Since nutrient needs vary based on the individual, here are a few basic things to look for in a multivitamin for your child with autism:
1. A well-rounded nutrient profile
Look for key nutrients that are commonly lacking, like:
All 4 fat-soluble vitamins (A, D, E, K)
All 8 B vitamins
Vitamin C
Minerals including zinc, magnesium, selenium, and iodine
Specific brain-support nutrients like choline and inositol
It's important to note that not every multivitamin will include meaningful amounts of these nutrients, or the right forms. But we want to make sure first that they are present!
2. High-quality, absorbable forms
The form of a nutrient matters just as much as the amount.
For example:
Methylated B vitamins instead of synthetic forms like folic acid or cyanocobalamin
Minerals that are buffered are easier on digestion and better absorbed
This is often where cheaper or conventional vitamins fall short.
3. Minimal unnecessary additives
Artificial colors, flavors, and fillers can:
Add low quality & artificial ingredients that many kids are sensitive to
Be a dealbreaker for sensory-sensitive kids
After my email yesterday, a lot of you were thinking:
“Okay… but how do I actually choose a good multivitamin?”
Because the truth is—
👉 Not all multivitamins are created equal.
And this matters even more for kids on the spectrum.
So here are 5 things I recommend looking for:
1. A well-rounded nutrient profile
Look for key nutrients that are commonly lacking, like:
All 4 fat-soluble vitamins (A, D, E, K)
All 8 B vitamins
Vitamin C
Minerals including zinc, magnesium, selenium, and iodine
Iron is best taken separately as it can affect the absorption of other minerals, and should be excluded from multivitamins.
Specific brain-support nutrients like choline and inositol
It's important to note that not every multivitamin will include meaningful amounts of these nutrients, or the right forms. But we want to make sure first that they are present!
2. High-quality, absorbable forms
The form of a nutrient matters just as much as the amount.
For example:
Methylated B vitamins instead of synthetic forms like folic acid or cyanocobalamin
Minerals that are buffered are easier on digestion and better absorbed
This is often where cheaper or conventional vitamins fall short.
3. Minimal unnecessary additives
Artificial colors, flavors, and fillers can:
Add low quality & artificial ingredients that many kids are sensitive to
Be a dealbreaker for sensory-sensitive kids
4. Sensory-friendly taste, texture, and smell
This is HUGE.
Because if your child won’t take it…
nothing else matters.
This is one of the biggest reasons parents tell me:
👉 “We’ve tried vitamins before and it didn’t go well.”
5. Third-party testing for quality and safety
This means the product has been independently tested to verify:
What’s on the label is actually in the product
That it’s free from contaminants & heavy metals
This is one of the best ways to ensure you’re getting a safe and reliable supplement.
6. Designed with real-life eating patterns in mind
Not just a generic “kids vitamin”, but something that actually considers:
limited diets
sensory preferences
and the nutrient gaps we commonly see in kids on the spectrum
Other Multivitamin Tips
Choose multivitamins with at least 100% of all B vitamins. Fat-soluble vitamins and minerals may not reach 100%, and that’s okay. These are typically made up in the diet. Excessive levels of fat-soluble vitamins can build up in the body and become toxic while water-soluble vitamins will be excreted in the urine.
Take multivitamins at meals to prevent upset stomach or nausea
To increase absorption, take with meals
Some individuals find it hard to sleep after taking a multivitamin at night, so evaluate for tolerance.

My Favorite Multivitamins for Kids on the Autism Spectrum:
Multivitamin Powders (Typically Easiest for Selective Eaters)
⭐️ Best Part Multivitamin: This exceeds all of my standards and is built for sensory-sensitive kids who usually refuse. It comes in an unflavored option and a mixed berry flavor (that is delicious) and features organic raspberry powder and organic beetroot powder.
Shop Unflavored on Amazon
Shop Berry on Amazon
Multivitamin liquid
Multivitamin Capsules
Multivitamin Gummies
For added iron…
I do not recommend multivitamins with added iron as it affects absorption of other minerals. I recommend taking away from multivitamins and dairy products for optimal absorption. For added absorption, pair with vitamin C. Check out my blog “How to Spot the Signs of Iron Deficiency and How To Treat It”
Liquid: Pure Encapsulations Liquid Iron
Chewable: Carlson Chewable Iron
Dissolvable tablet: Renzo’s Iron Strong Vitamin
