First Day Vitamins Review

First Day has emerged as a premium family-focused vitamin brand promising organic ingredients, thoughtful formulations, and flavors kids actually love. With over 5,000 five-star reviews and endorsements from pediatricians, these gummy multivitamins target the nutritional gaps plaguing modern diets. But do they justify the premium price tag? This comprehensive review examines the effectiveness, safety, taste, and value of First Day vitamins for kids, teens, and adults to help you decide if they’re worth adding to your family’s routine.

What Are First Day Vitamins?

First Day is a subscription-based vitamin company specializing in gummy multivitamins and synbiotic supplements for the whole family. Founded with the mission to address “hidden hunger”—nutritional deficiencies despite adequate calorie intake—the company creates age-specific formulas for kids (ages 4+), toddlers (ages 2-3), teens, and adults (both men and women). Unlike many competitors that oversupplement with mega-doses, First Day follows a philosophy of providing only what research shows most people lack.

The brand distinguishes itself through several key features: all vitamins contain a blend of 12 organic fruits and vegetables including kale, broccoli, apples, and berries. They’re free from artificial flavors, colors, sweeteners, and common allergens. The methylated B vitamins in their formulas are easier to absorb, particularly beneficial for those with MTHFR gene variations. First Day also offers synbiotic supplements combining prebiotics, probiotics, and postbiotics for comprehensive gut health support.

Each product undergoes third-party testing at least three times during manufacturing, adhering to German quality standards that exceed typical U.S. requirements. The company operates on a subscription model with 15% savings and free shipping, though first-time buyers can try products with a 45-day satisfaction guarantee. The reusable glass bottle you receive initially is refilled monthly with compostable pouches, reducing plastic waste.

First Day Kids Multivitamin Review

Best For: Children ages 4+ needing comprehensive nutritional support

The First Day Kids Daily Essential Vitamins pack 9 crucial micronutrients that children commonly lack: vitamins A, C, D3, K2, E, B1, B2, B6, B12, and folate (methylated). Each gummy delivers more vitamin D than 200 mushrooms, addressing the widespread deficiency affecting children’s bone development and immune function. The formula is specifically calibrated to fill gaps without over-supplementing, following recommended daily allowances rather than providing excessive amounts.

Parents consistently praise the strawberry-orange flavor—kids genuinely enjoy taking these vitamins, eliminating the daily battle many families face. The gummies aren’t overly sweet or candy-like, containing just 2 grams of organic cane sugar per serving. Multiple reviews mention improvements in children’s focus, mood, and energy levels within weeks. One parent noted their child with ADHD showed fewer meltdowns and better concentration after starting First Day vitamins.

The organic blend of 21 superfoods provides antioxidants and phytonutrients research suggests are better absorbed than synthetic alternatives. However, the exact quantities of these fruits and vegetables aren’t disclosed on the label, making it impossible to verify equivalency to actual produce servings. The formula notably lacks iron, so vegetarian/vegan children or those with iron deficiency need additional supplementation.

Pros: Great taste kids love, organic ingredients, methylated B vitamins, addresses common deficiencies, third-party tested, improvements in mood and focus reported

Cons: Premium pricing at $39/month, no iron included, fruit/vegetable blend amounts not disclosed, contains added sugar, subscription model may feel pushy

First Day Teen Vitamins Review

Best For: Teenagers 13-17 experiencing growth spurts and academic stress

Teen formulas recognize that adolescents have unique nutritional needs during this rapid growth period. The vitamin profile mirrors the kids’ version but with adjusted dosages appropriate for larger bodies and higher metabolic demands. B vitamins are particularly emphasized to support energy metabolism, brain function, and stress management—crucial during exam seasons and extracurricular pressures.

Teenage reviewers report actually remembering to take these vitamins without parental reminders, which speaks volumes about palatability and form factor. Several parents note their athletic teens rely on First Day to support recovery and performance, appreciating that the gummies don’t seem “babyish.” Multiple families mention improvements in teenage mood swings and anxiety symptoms, though these benefits likely stem from correcting underlying B vitamin and vitamin D deficiencies rather than any unique ingredients.

The teen formula faces the same criticisms as the kids’ version: no iron, undisclosed amounts of the organic fruit/vegetable blend, and premium pricing. For families with multiple teenagers, costs can exceed $100 monthly. Some parents question whether the benefits justify this investment compared to high-quality alternatives from brands like Hiya or standard multivitamins from Nature Made.

Pros: Teens actually want to take them, supports focus and energy, appropriate dosing for growth period, methylated folate helps those with MTHFR, positive impact on mood

Cons: Expensive for multi-teen households, missing iron and other minerals, added sugar content, may not address severe deficiencies

First Day Adult Vitamins Review

Best For: Health-conscious adults seeking convenient nutritional insurance

First Day offers separate formulas for men and women, acknowledging different nutritional needs between sexes. The Women’s Daily Essential includes biotin for hair/skin/nails, while Men’s Daily Essential focuses more on energy and immune support. Both provide methylated B12, vitamin D3, vitamin E, vitamin C, and the signature organic fruit/vegetable blend. Each serving is four gummies daily.

Women report improvements in energy, reduced fatigue (particularly postpartum mothers), and better hair/skin health after several weeks. The mango flavor receives consistent praise for tasting like a treat rather than a chore. Several reviews mention First Day successfully replaced individual D3 and B12 supplements they were taking separately. Men appreciate the non-chalky texture and find the routine easy to maintain.

However, these adult formulas face legitimate criticism from nutritionists. They contain citric acid, which may cause inflammation in sensitive individuals, and natural flavors—a vague term that doesn’t disclose specific ingredients. The 2 grams of added sugar per serving concerns health professionals, especially for adults already consuming excess sugar. Most significantly, the dosages are relatively modest compared to therapeutic amounts used in deficiency treatment. These work well as maintenance vitamins for generally healthy adults but won’t dramatically improve serious nutritional gaps.

Pros: Tastes good enough to remember daily, replaces multiple individual supplements, methylated B vitamins, organic ingredients, positive energy and mood effects

Cons: Contains added sugar and citric acid, relatively low dosages, expensive compared to pill alternatives, not suitable as prenatal (missing choline and adequate folate), subscription requirement

First Day Synbiotic (Pre/Pro/Postbiotic) Review

Best For: Supporting gut health and enhancing vitamin absorption

The First Day Triple Biotic goes beyond standard probiotics by including prebiotics (fiber that feeds beneficial bacteria) and postbiotics (metabolic byproducts of probiotic bacteria). This comprehensive approach addresses the entire gut microbiome cycle. The formula contains clinically-studied strains backed by human research, distinguishing it from many probiotic products that use random strains without evidence.

Parents report improvements in their children’s digestion, regularity, and reduced illness frequency. The synbiotic enhances nutrient absorption from both food and the multivitamin, potentially making the entire First Day system more effective than either product alone. Several families with children prone to frequent colds and stomach issues noticed fewer sick days after adding the probiotic.

The main drawback is cost—adding the synbiotic to your subscription increases monthly expenses significantly. Some children experience initial digestive adjustment (gas, minor bloating) for the first week, though this typically resolves. The formula requires refrigeration after opening, which can be inconvenient for families who travel frequently or forget to bring vitamins on trips.

Pros: Comprehensive pre/pro/postbiotic approach, clinically-studied strains, improves vitamin absorption, reduces illness frequency, supports gut health

Cons: Adds substantial cost, requires refrigeration, initial digestive adjustment period, effectiveness varies by individual

Effectiveness and Safety

First Day’s effectiveness stems primarily from addressing common nutritional deficiencies rather than any revolutionary formulation. The vitamins provide nutrients research shows Americans—particularly children—consistently lack: vitamin D, vitamin E, vitamin C, and B vitamins. By correcting these deficiencies, users experience real benefits like improved energy, better mood, stronger immunity, and enhanced focus.

The methylated B vitamins (methylfolate and methylcobalamin) represent a genuine advantage, especially for the estimated 40% of people with MTHFR gene variations who struggle to convert synthetic folic acid and cyanocobalamin. This thoughtful formulation detail shows First Day’s commitment to bioavailable nutrients. The organic fruit and vegetable blend, while lacking disclosed amounts, provides phytonutrients and antioxidants that synthetic vitamins miss.

Safety appears solid with multiple layers of third-party testing exceeding FDA requirements (which don’t regulate supplements as strictly as pharmaceuticals). German manufacturing standards add another quality assurance layer. The company transparently lists all ingredients and provides detailed information about sourcing. No recalls or safety concerns have been publicly reported.

However, effectiveness limitations exist. The dosages are calibrated for deficiency prevention rather than treatment, meaning someone with severe vitamin D deficiency won’t reach optimal levels with First Day alone. The lack of iron is problematic for children who need it most—vegetarians, vegans, and those with diagnosed deficiency. The formula won’t replace a balanced diet full of fruits, vegetables, and whole foods; it merely supplements an imperfect one.

Taste and Convenience

Taste is First Day’s standout feature. Unlike chalky pills or unpleasant liquid vitamins, these gummies genuinely taste good enough that children request them and adults look forward to them. The strawberry-orange flavor for kids strikes the perfect balance—fruity and pleasant without being candy-like. Teen and adult flavors also receive consistent praise. This isn’t trivial; supplement compliance depends heavily on palatability, especially with children.

The gummy format has advantages and disadvantages. On the plus side, they’re easy to chew, don’t require water, and eliminate swallowing large pills. Kids who refuse traditional vitamins readily take gummies. However, gummy vitamins inherently contain sugar (or sugar alcohols in sugar-free versions) to mask vitamin taste, adding calories and potentially contributing to dental concerns if kids don’t brush afterward. The gelatin in most gummies comes from animal sources, though First Day uses plant-based pectin for their vegan formula.

The subscription model provides convenience—vitamins arrive automatically monthly with refill pouches for your reusable bottle. This eco-friendly approach reduces plastic waste and eliminates remembering to reorder. However, multiple reviewers found the subscription confusing, accidentally receiving multiple shipments or struggling to cancel. The company charges for each product subscription separately, so families taking multiple formulas may receive deliveries at different times unless carefully coordinated.

Cost and Value Analysis

First Day vitamins cost $39 per month with subscription (15% off the $45 one-time purchase price). For a family of four taking multiple products, monthly costs easily exceed $120-150. This premium pricing puts First Day among the most expensive multivitamin options on the market. By comparison, quality children’s multivitamins from Nature Made or SmartyPants cost $10-20 monthly, and adult versions even less.

Does the quality justify the cost? It depends on your priorities and budget. First Day delivers on its promises: organic ingredients, thoughtful formulations, third-party testing, methylated vitamins, and taste that ensures compliance. These aren’t empty promises—reviews consistently confirm children actually take these vitamins happily, which alone may justify costs for families battling vitamin refusal.

However, the nutritional value per dollar doesn’t compare favorably to alternatives. Brands like Hiya offer similar quality with zero added sugar for comparable or lower prices. Standard multivitamins from reputable manufacturers like Nature Made provide adequate nutrition at a fraction of the cost, though with synthetic rather than food-based vitamins. For families on tight budgets, First Day represents a luxury rather than necessity.

The 45-day satisfaction guarantee reduces financial risk for first-time buyers. This allows families to test whether their children will actually take the vitamins and whether they notice benefits before committing long-term. The subscription can be paused, skipped, or canceled, though some customers report difficulty navigating this process.

Frequently Asked Questions

Are First Day vitamins worth the money?

First Day vitamins are worth it if taste and compliance are your primary concerns and budget isn’t restrictive. The organic ingredients, methylated vitamins, and excellent flavor justify the premium for families who’ve struggled with vitamin refusal. However, comparable quality exists at lower prices from brands like Hiya or SmartyPants if willing to compromise on the organic fruit/vegetable blend.

Do First Day vitamins actually work?

Yes, First Day vitamins work by addressing common nutritional deficiencies, particularly vitamin D, B vitamins, and vitamin E. Users report genuine improvements in energy, mood, focus, and immunity. However, they work best for deficiency prevention rather than treatment of severe deficiencies, and benefits depend on your starting nutritional status.

Are First Day vitamins safe for toddlers and young children?

First Day offers a toddler formula for ages 2-3 that’s specifically calibrated for younger children. The standard kids’ vitamins are designed for ages 4+. Both are generally safe when taken as directed, though you should consult your pediatrician before starting any supplement, especially if your child has medical conditions or takes medications.

Can adults take First Day kids vitamins?

While physically safe, adults shouldn’t rely on kids’ vitamins as they contain lower doses inappropriate for adult needs. First Day offers separate adult formulas for men and women with age-appropriate dosing. Taking kids’ vitamins would require consuming many more gummies to meet adult requirements, negating any cost savings.

Why don’t First Day vitamins contain iron?

First Day explains they excluded iron because most children get adequate iron from diet, and excessive iron supplementation can cause side effects. This is a reasonable approach for most kids, but vegetarian/vegan children or those with diagnosed iron deficiency need separate iron supplementation. Always have your child’s iron levels checked if concerned.

How do First Day vitamins compare to Hiya?

First Day and Hiya are similar premium brands with key differences: First Day uses organic fruits/vegetables and comes in gummy form with small amounts of sugar, while Hiya uses a chewable tablet with zero sugar and higher vitamin doses. Some doctors prefer First Day’s approach of not over-supplementing; others prefer Hiya’s sugar-free format. Both have loyal followings and positive reviews.

Can I cancel my First Day subscription easily?

Cancellation policies have improved, but some customers report confusion with the system. You must cancel each product subscription separately, which isn’t always clear. Contact customer service directly if you have trouble—they’re generally responsive and helpful in resolving subscription issues, though managing it yourself online can be tricky.

Do First Day vitamins help with picky eaters?

First Day vitamins can help fill nutritional gaps in picky eaters who refuse vegetables and fruits. However, they don’t replace the fiber, phytonutrients, and other compounds found in whole foods. Use them as nutritional insurance while continuing to encourage varied eating, not as a substitute for addressing picky eating behaviors.

The Verdict

First Day vitamins deliver on their core promise: providing high-quality, great-tasting supplements that address common nutritional deficiencies in families. The organic ingredients, methylated vitamins, thoughtful formulations, and rigorous testing justify calling these premium products. For families who’ve struggled with vitamin compliance or want peace of mind about ingredient quality, First Day represents a solid investment.

However, “premium” doesn’t mean “necessary” or even “best value.” Comparable nutritional support exists at lower prices from reputable brands. The added sugar, lack of iron, and modest dosages mean First Day works better for maintaining good nutrition than correcting serious deficiencies. The subscription model and cost structure make this more of a luxury than an essential purchase for most families.

Ultimately, First Day vitamins are worth trying if taste, organic ingredients, and compliance are your priorities and the cost fits comfortably in your budget. Take advantage of the 45-day guarantee to test whether you notice benefits and whether your family will consistently take them. For those on tighter budgets, excellent alternatives from Nature Made, SmartyPants, or Hiya provide quality nutrition without the premium price tag.
