First Day Vitamins Review: Are These Organic Gummies the Best Kids’ Multivitamin?

In partnership with First Day

A picky kid and a full plate of vegetables can turn into a daily standoff, and the numbers back up the struggle. By most counts, more than 90% of children don’t eat enough vegetables, which leaves real gaps in the nutrients they need to grow. Plenty of parents reach for a gummy vitamin to bridge that gap, only to find most options loaded with added sugar and artificial dyes.

First Day, made by First Day Life Inc., built its kids’ multivitamin around a different idea. Real organic fruits and vegetables, a short ingredient list, and far less sugar than the drugstore standbys. The brand has since grown into a daily routine for more than a million families.

The kids’ formula leans on nine essential nutrients and a blend of 21 organic superfoods, with up to 75% less sugar than some popular children’s gummies and no artificial dyes or sweeteners. It’s vegan, non-GMO, free from the top nine allergens, and Clean Label Certified, with a medical advisory board that includes a Yale pediatrician and a Harvard nutrition professor.

Whether a low-sugar, food-based gummy that intentionally stays under 100% of daily values can justify its premium price is the question worth answering. The rest of this review gets into the formula, the cost, and what parents actually report.

First Day Review

First Day positions its kids’ gummies as a real-food alternative to the sugary, brightly dyed vitamins most parents grew up handing out. The pitch is that a short list of recognizable ingredients, backed by current pediatric research, beats a long list of synthetic ones. What follows looks at the formula behind that claim, how the nutrient levels are set, what the gummies cost on a subscription versus one-time basis, and where parent feedback lands after more than a million families have tried them.

Unique Features

1. Bio-Matched to every life stage

First Day formulas are built to match a child’s actual stage, not just the age on the box, since a 3-year-old and a 14-year-old don’t need the same things. The brand approaches matches in three ways. It chooses nutrient forms that a child’s body is designed to recognize and absorb, rather than cheaper chemical forms that can pass through with little benefit. It formulates each ingredient so it actually reaches the bloodstream rather than sitting unused. And it pairs nutrients at ratios that help them work together, since vitamin D supports calcium absorption and vitamin C improves iron uptake, while some nutrients compete when combined the wrong way.

2. A blend of 21 organic superfoods

Every gummy contains a blend of 21 organic fruits and vegetables, including apple, kale, broccoli, spinach, carrot, beet, blueberry, turmeric, and ginger, as well as mushrooms like reishi and lion’s mane. The idea is to deliver antioxidants and phytonutrients from recognizable food sources rather than from synthetic additives, which is the core of the brand’s “No Junk” label.

3. Nine essential nutrients dosed to fill gaps

The formula covers vitamins A, C, D3, B1, B2, B6, B12, folate, and K2. Rather than chasing 100% or more of every daily value, First Day keeps levels measured, on the logic that a child’s diet already supplies some nutrients and that excess amounts of certain vitamins offer no benefit. The aim is to top up what’s commonly missing, not to overload.

4. Up to 75% less sugar and no artificial sweeteners

Where many children’s gummies double as candy, First Day uses around 2 grams of sugar per serving, up to 75% less than some popular competitors. Sweetness comes from fruit-based natural flavors instead of artificial sweeteners or sugar alcohols, and the color comes from carrot, blackcurrant, and red bell pepper juice rather than synthetic dyes.

5. Free from the top nine allergens, vegan, and non-GMO

The kids’ gummy is dairy-free, soy-free, egg-free, gluten-free, peanut-free, tree-nut-free, fish-free, shellfish-free, and sesame-free, which covers the nine major allergens. It’s also vegan, non-GMO, and cruelty-free, a combination that is a real plus for households juggling food sensitivities.

6. Clean Label Certified and tested for purity

First Day carries Clean Label Project certification and says its gummies are repeatedly tested for potency and purity. For a category where what’s on the label doesn’t always match what’s in the bottle, third-party testing is a meaningful trust signal.

7. Built on pediatric research with a medical board

First Day says it reviewed more than 35,000 studies on pediatric health while developing the formula, and its scientific advisors include Dr. Lei Chen, a pediatrician at Yale, and Dr. Ed Giovannucci, a nutrition and epidemiology professor at Harvard. That academic backing is rare among direct-to-consumer gummy brands.

8. Refillable packaging and a subscription model

First orders ship in a reusable bottle, and subscription refills arrive in eco-friendly pouches every 30 days. The subscription lowers the per-bottle cost, adds free shipping, and can be paused or cancelled at any time.

Benefits

What tends to win parents over is what those ingredients actually do in a real household, from calmer mornings to fewer worries on the label. Here’s where First Day earns its place day to day.

1. An End to the Daily Vitamin Battle

Consider the parent who has tried three different gummies, each rejected after a single bite. First Day’s strawberry-and-orange flavor and soft texture are why so much of its feedback comes from picky-eater households. The vitamin a child actually asks for beats the perfect formula they refuse to touch.

2. Nutrition Gaps, Covered

Think about the typical week, where a kid eats around the vegetables more often than through them. With most children falling short on produce, the nine nutrients and superfood blend top up what a picky diet tends to miss, so a parent isn’t leaning on dinnertime alone to cover the bases.

3. Cleaner Ingredients Without the Sugar Crash

Consider a parent scanning a standard children’s gummy and finding more sugar than a cookie, plus dyes they can’t place. First Day answers that with roughly 2 grams of sugar and color drawn from real fruit and vegetable juice, so the daily vitamin doesn’t double as candy.

4. One Less Worry for Allergy Households

Think about a home managing a nut or dairy allergy, where every new product means reading the fine print twice. Free from all nine major allergens and made vegan and non-GMO, First Day takes one item off that checklist.

5. A Routine That Runs Itself

Consider the month a bottle runs empty and the vitamins quietly stop. The subscription ships a refill every 30 days with an ongoing discount and free first-order shipping, which keeps the habit going without a calendar reminder.

How Much Does First Day Vitamins Cost?

First Day sells the Kids’ Multivitamin in a single 30-serving size, with the price depending on how you buy it. The subscription is where the real savings sit.

1. One-time purchase – $39

• A single bottle, 30 servings, no commitment
• Often discounted with an active promo code

2. Subscription – about $23.40 per bottle (roughly 40% off)

• 30 servings shipped every 30 days
• Free shipping on the first order and 15% off ongoing
• Refillable bottle plus eco-friendly refill pouches
• Pause or cancel anytime

Compared with drugstore gummies, First Day sits at the premium end, and the headline price can look steep next to a bottle of Flintstones. The subscription narrows that gap considerably, and a 45-day money-back guarantee covers up to three bottles, so a family can test it with little risk. Multi-bottle orders and seasonal sales drop the per-bottle cost further.

First Day Review: What Do Customers Think?

First Day reports a 4.8-star average and more than a million families served, and the Kids’ Multivitamin alone holds roughly 4,900 reviews with about 87% at five stars. The most consistent praise, by a wide margin, is taste, especially from parents of picky eaters who had given up on other brands.

One parent wrote, “My son is very sensitive to flavors, and these are the only vitamins he’ll eat. Thank you for making them taste good.” That theme repeats often, as in another short review, “The only vitamin (out of many) that my kid will actually eat.”

Parents also point to the simplicity of the ingredients as a reason they switched. “I love how simple the ingredients are to understand. As a parent, it’s a no-brainer,” one reviewer noted. Some describe changes in their child’s mood or focus, though those accounts are individual experiences rather than guaranteed outcomes, and First Day’s mood and behavior figures come from its own customer surveys rather than clinical trials.

The fairest read is that the taste and clean-ingredient claims hold up strongly in feedback, while the wellness outcomes vary child to child. 

Is First Day Legit?

Yes, First Day is a legitimate company. It operates as First Day Life Inc., has served more than a million families, carries Clean Label Project certification, and says its products are third-party tested for potency and purity. Its formulas were developed with a medical advisory board out of Yale and Harvard, it’s been featured by outlets including Yahoo Finance, and every order carries a 45-day money-back guarantee. As with any dietary supplement, the statements about its benefits have not been evaluated by the FDA, and the product isn’t meant to diagnose, treat, cure, or prevent any disease, so it’s wise to check with a pediatrician before adding it to a child’s routine.

Is First Day Vitamins Worth It?

or parents who want a clean, low-sugar gummy their kid will actually take, First Day is an easy yes. The real-food superfood blend, the absence of artificial dyes and sweeteners, the allergen-friendly formula, and the Yale and Harvard backing make this one of the strongest picks in the kids’ vitamin aisle. On subscription it runs about $23 a month, which puts a premium, clean-label gummy within reach of a normal grocery budget.

The trade-offs are easy to plan around. The formula stays under 100% of daily values and skips iron and calcium on purpose, so it tops up a child’s diet rather than replacing a doctor-directed supplement for a specific deficiency. It still carries roughly 2 grams of cane sugar, and the mood and behavior figures come from First Day’s own customer surveys rather than clinical trials. None of that undercuts what the gummy is built to do.

For the right household, a parent who values clean ingredients, low sugar, and a vitamin that ends the morning standoff, First Day earns its spot. Pair it with a quick word from your pediatrician about what your child actually needs, and it stands as one of the best daily gummies you can hand a kid.

First Day Discounts and Promotions

First Day leans on a few steady savings rather than one-off gimmicks, and stacking the right ones brings the real cost well below the sticker price. Here’s what’s on the table right now.

• Subscribe and save. Subscription orders run about 40% below the one-time price, with 15% off ongoing and free shipping on the first order.
• Current sale. A seasonal promo (code PRIMEDEALS at the time of writing) advertises up to 52% off, plus a free electrolyte hydration gift on orders over $75.
• Money-back guarantee. You have 45 days to try it, covering up to three bottles, refunded if a family isn’t satisfied.
• Rewards and referrals. A VIP rewards program earns points on purchases, and a refer-a-friend program offers additional savings.

Where Can I Buy First Day?

First Day sells directly through firstday.com, where the full lineup, subscription options, and current promotions live. A store locator on the site lists retail availability, but buying direct is the most reliable way to get the current pricing, the money-back guarantee, and the subscription perks. The official site is also the safest route, since third-party sellers may not honor the guarantee.

FAQs

What age is the First Day Kids’ Multivitamin for?

It’s formulated for children ages 4 to 12. First Day makes separate formulas for toddlers ages 2 to 3 and teens ages 13 to 17, so the nutrient levels match the age group.

How many gummies does a child take?

The serving is two gummies per day, and each bottle holds 30 servings, which is a one-month supply for one child.

Does it contain iron or calcium?

No. The formula focuses on nine commonly under-consumed nutrients and intentionally stays under 100% of daily values, so it doesn’t include iron or meaningful calcium. It’s designed to fill gaps alongside a balanced diet, not to replace a doctor-directed supplement for a specific deficiency.

How much sugar is in it?

Around 2 grams per serving, which First Day says is up to 75% less than some popular children’s gummies. Sweetness comes from fruit-based natural flavors rather than artificial sweeteners or sugar alcohols.

Is it safe and allergen-friendly?

The gummies are free from all nine major allergens and are vegan, non-GMO, and free from artificial colors and flavors. As with any supplement, the claims aren’t FDA-evaluated, so checking with a pediatrician first is the right move, especially for a child with existing conditions.

Do I have to subscribe?

No. First Day offers a one-time purchase, but the subscription brings the per-bottle price down, adds free shipping and a 15% ongoing discount, and can be paused or cancelled at any time.
