Why Best Part Was Formulated Differently

Registered dietitian Brittyn Coleman created Best Part after years of working with families navigating selective eating and supplement refusal.

The goal was simple: a higher-quality multivitamin with meaningful nutrient forms, clear amounts, and a powder format that could fit real routines.

A Daily Vitamin My Daughter Enjoys

"My daughter has been taking this multivitamin for a little over two months now, and I can honestly say it has become one of the easiest and most successful additions to our morning routine.

For context, my daughter is a very selective eater, so finding nutritional products she will consistently take has always been a challenge. We’ve tried other vitamins before, and most ended up abandoned after a few days because she didn’t like the taste or texture. This one has been completely different.

The powder dissolves very well in water, which I appreciate because there’s no gritty texture or clumping. The flavor tastes smooth and pleasant without being overly sweet or artificial.

After a little over two months of using it consistently, I’ve noticed several positive changes:

- She seems to have more steady energy throughout the day
- Her mood has noticeably improved
- She’s been more social and engaged"

Leagues better in vitamin content

"This is truly the best multivitamin. My son is a very picky eater and very sensitive to new tastes or textures, so the only way I have been able to get a multi in him is flavorless powder.

This one is leagues better in vitamin content than all the others I know about.

We typically mix it into mac & cheese. Sometimes I have mixed it into the frosting for cinnamon rolls! It still has a slight vitamin flavor, so I definitely think you need a “food” to hide the taste.

If your child likes smoothies or yogurt it would be great in there too!"

Designed for selective eaters

Better nutrient forms, clear amounts, and a smooth powder made for real selective eating routines.

Smooth, Easy-to-Mix Powder

Most kids’ vitamins are designed for flavor or label marketing.

This one was built for real routines, where taste, texture, and predictability actually matter.

Best Part was designed specifically for children with sensory sensitivities and selective eating patterns by a Registered Dietitian who works with families experiencing selective eating daily.

You don't have to choose between quality and sensory-friendly anymore.

Thoughtfully Chosen, Bioavailable Forms

Selective eaters often have real nutritional gaps.

Best Part focuses on bioavailable forms and intentional dosing designed to help fill those gaps, without extreme megadoses or unnecessary ingredients.

All ingredients were thoughtfully selected - like methylated B Vitamins and chelated minerals.

Full Label Transparency

Parents deserve to know exactly what they’re giving their child.

Every nutrient and amount is listed clearly. No proprietary blends, no hidden doses, and no “fairy dust” ingredients.

We don't believe in hiding nutrient amounts from parents.

Every batch is rigorously 3rd-party tested.

Built for Real-Life Routines (Not Perfect Ones)

Supplements only help if they become part of a routine.

Best Part mixes quickly into water, juice, or food and is designed to fit into daily routines without adding another battle.

And when you purchase, we'll help you figure out the best way to give Best Part to your child without hiding them or risking their safe foods.

What makes Best Part different

Try Best Part

Full transparency. No hidden ingredients.

Parents deserve to know exactly what their child is getting, without having to guess what’s in a proprietary blend

Essential vitamins, clearly listed

No blends or hidden amounts. Every vitamin and dose is listed directly on the label so parents can see exactly what their child is getting.

Active B vitamins (ready to use)

We use active forms like methylfolate, methylated B12, and P5P so the body can use them more efficiently — without relying on megadoses

Minerals chosen for absorption

Chelated mineral forms like magnesium bisglycinate and zinc bisglycinate are often easier to absorb and gentler on the stomach.

Extra Brain Support

Ingredients like choline and inositol help fill nutritional gaps common in selective eating that help support healthy brain development.

REGISTERED DIETITIAN FOUNDED

Why Best Part was created

I’m Brittyn, a registered dietitian who has spent over a decade working with families navigating selective eating.

Over and over, I saw the same pattern: parents trying to support their child’s nutrition, but struggling to find something their child would realistically accept.

Most options didn’t fit real life. They either focused on taste or on nutrition, but rarely both in a way that worked for selective eaters.

Best Part was created to change that.

A daily multivitamin designed to support selective eaters with a sensory-friendly approach, so nutrition can feel like something that fits into your life, not something that adds more pressure.

Frequently asked questions

Common questions parents ask when starting Best Part

  • Why is Best Part a powder instead of a gummy or liquid?

    Best Part is a powder because it gives families more flexibility and lets us focus on meaningful, well-absorbed nutrients without relying on added sugars, colors, or unnecessary extras. Powders also make it easier to adjust how it’s served based on your child’s preferences, instead of expecting your child to adapt to the supplement.

  • What is it like to take Best Part?

    Best Part was designed to be as low-sensory as possible. Both options mix smoothly, have minimal grit or residue, and no strong vitamin smell. Unflavored is extremely mild with no added sweetness, while Mixed Berry has a noticeable berry flavor that’s gently sweet without being overpowering.

  • What if my child refuses it at first?

    That’s very common, and completely okay. Many children need time and gentle exposure before something new feels comfortable, so it’s okay to start small, keep things low-pressure, and try again later if needed. We also include a guide with sensory-informed, child-led strategies to help you introduce it in a way that builds trust.

  • Is Best Part safe for daily, long-term use?

    Yes. Best Part was designed with daily use in mind, using thoughtful, safety-first dosing and nutrient forms chosen for consistent everyday use. The goal is something you can feel good about using regularly, not something that adds more stress to your routine.

  • Is Best Part third-party tested?

    Yes. Every batch is third-party tested for purity and quality, screened for heavy metals, microbes, and contaminants, and verified for ingredient and nutrient accuracy. Best Part is also made without artificial colors, added sugars, unnecessary fillers, and common allergens like dairy, soy, gluten, and nuts.

  • How should I give Best Part to my child?

    Start simple. We recommend mixing it into water, juice, or another accepted drink and offering it as its own small, predictable routine. Many families start with a smaller amount and build up gradually, especially when introducing something new to a selective eater.

  • Can children without selective eating or sensory challenges take Best Part?

    Absolutely! Best Part was designed with selective eating and sensory sensitivity in mind, but it can be used by any child.

    Some families come to it because their child refuses most supplements. Others simply want a consistent, low-stress way to help fill common nutritional gaps as part of a daily routine.

    What makes it different is how it’s built: a smooth powder that dissolves fully in a small amount of liquid, with no chalky grit and no strong vitamin smell.

    • The Unflavored version is very mild and neutral, for kids who notice everything
    • The Berry version has a noticeable, real berry flavor that’s not overly sweet or candy-like

    Even if your child doesn’t have sensory challenges, those details can make it easier to introduce and stick with.

    You can mix it into water, milk, or simple foods or drinks. Just keep it predictable and avoid hiding it in a strongly preferred food.

    The goal is to build trust and a routine your child feels okay with.

    Most families appreciate that Best Part is created without added sugar or artificial dyes, and is free from gluten, soy, and dairy.

  • Is Best Part available outside the US?

    Unfortunately, we are only available in the US for now.

    We are hoping to expand internationally as soon as possible.
