First Day is a legitimate vitamin company that sells organic gummy multivitamins for kids, women, and men. It’s a real brand with a real product line, not a scam. But “legit” probably means more to you than just “not fake.” You want to know whether the vitamins are well-formulated, whether the company is transparent, and whether the product is worth the premium price. The answers are mixed.
What’s Actually in the Vitamins
First Day’s flagship kids multivitamin is a vegan gummy made with a blend of 21 organic fruits and vegetables, which the company says provides antioxidants and phytonutrients alongside the standard vitamin lineup. The product is labeled non-GMO and gluten-free.
Where First Day stands out from many drugstore gummy brands is in the forms of vitamins it uses. The B12 is included as methylcobalamin, which is the naturally occurring form found in food rather than the synthetic cyanocobalamin used in cheaper supplements. Folate is provided as methylfolate, the active form your body can use without needing to convert it first. This matters because a meaningful percentage of the population has genetic variations that make converting standard folic acid inefficient. Vitamin D3 comes from lichen (a plant-based source of cholecalciferol), and vitamin A is included as beta-carotene from whole-food sources rather than synthetic retinyl palmitate.
These are genuinely better ingredient choices. Using bioavailable forms of B vitamins and plant-sourced D3 reflects current nutritional science and puts First Day a step above many competitors that use cheaper synthetic versions.
The Sugar Question
Gummy vitamins across the board rely on sugar or sugar substitutes to taste good, and First Day is no exception. Many gummy vitamins contain one or more grams of sugar per gummy, and some varieties pack up to three different types of sweeteners into a single product. First Day markets its use of organic fruit blends as a cleaner approach, but gummies are still gummies. If added sugar is a concern for your kids, a capsule or tablet form from another brand will always win on that front.
Third-Party Testing: A Gap Worth Noting
This is where things get less impressive. Dietary supplements in the U.S. aren’t required to prove they work before hitting shelves. The gold standard for consumer trust is third-party certification from organizations like NSF International or USP, which test products to confirm they actually contain what the label says, in the amounts listed, without harmful contaminants like heavy metals. NSF, for example, conducts annual audits and periodically retests certified products against what it calls the toughest testing standard in the supplement industry.
First Day does not carry NSF or USP certification. The company doesn’t prominently advertise independent lab testing results on its website. That doesn’t mean the product is unsafe or inaccurately labeled, but it does mean you’re taking the company at its word. For a brand charging premium prices and marketing itself as a cut above, the absence of third-party verification is a notable gap.
How First Day Compares to Store Brands
The main advantages over a typical grocery store gummy vitamin are the bioavailable vitamin forms (methylcobalamin, methylfolate, plant-based D3), the organic fruit and vegetable blend, and the vegan formulation. Most mass-market gummy vitamins use cheaper synthetic forms, gelatin (which isn’t vegan), and multiple types of added sugar.
The tradeoff is price. First Day vitamins cost significantly more than brands like Flintstones or SmartyPants. You’re paying for cleaner ingredient forms and organic sourcing. Whether that premium is worth it depends on how much weight you put on bioavailability and organic certification versus simply covering basic nutritional gaps, which even a cheap multivitamin can do reasonably well.
Do Kids Actually Need These Vitamins
Most healthy children eating a reasonably varied diet don’t need a multivitamin at all. The nutrients where kids are most likely to fall short are vitamin D, iron, and calcium. The American Academy of Pediatrics specifically recommends that breastfed and partially breastfed infants get 400 IU of vitamin D daily starting in the first few days of life, and that recommendation extends to any child not drinking enough fortified milk.
B vitamins, which First Day emphasizes heavily, are abundant in common foods like meat, eggs, dairy, and fortified cereals. A B12 supplement makes more sense for kids on vegan or vegetarian diets, where dietary sources are limited. If your child eats animal products regularly, the B vitamin content of First Day isn’t filling a gap that food doesn’t already cover.
A targeted supplement addressing your child’s specific dietary gaps (vitamin D for a picky eater, B12 for a vegan kid) is often a smarter approach than a broad multivitamin.
Subscription and Refund Policies
First Day sells primarily through a subscription model on its website. You can manage, pause, or cancel your subscription through your account at any time, though changes can take up to 24 hours to process. The company recommends making updates at least one full day before your next renewal date to avoid being charged for another shipment.
The 45-day satisfaction guarantee sounds generous, but it comes with a catch: because the products are consumable, First Day doesn’t accept physical returns. If you’re unhappy, you email their support team with your order number, and they evaluate your eligibility for a refund on a case-by-case basis. That’s less of a firm guarantee and more of a “we’ll see what we can do” policy. It’s not unusual for supplement companies, but it’s worth knowing before you subscribe.
The Bottom Line on Legitimacy
First Day is a real company selling a real product with some genuinely thoughtful formulation choices. The use of methylated B vitamins, plant-based D3, and organic fruit blends reflects better-than-average ingredient quality. The concerns are the lack of independent third-party certification, the premium pricing, and the fact that most kids don’t need a comprehensive multivitamin in the first place. If you’ve decided your child needs a gummy vitamin and you’re willing to pay more for cleaner ingredient forms, First Day is a reasonable option. If you want verified purity and potency, look for brands that carry NSF or USP certification instead.
