About First Day
The online supplement brand First Day sells vitamins and related products designed for different age groups within a family. Its product range includes daily multivitamins, calming magnesium supplements, 3-in-1 prebiotic and probiotic formulas, and brain support supplements. These are marketed under categories such as Daily Vitamins, Calming Magnesium, 3-in-1 Probiotics, and Brain Support. The brand organizes its products by family member. For toddlers ages 2–3, it offers a multivitamin and a probiotic. For kids ages 4–12, it sells a multivitamin, a probiotic, a calming magnesium product, and a daily focus brain support supplement. Teens ages 13–17 have a similar lineup with a multivitamin, probiotic, magnesium, and brain support. Women and men ages 18 and older each have their own versions of these four product types. The products are described as organic multivitamin gummies, and the company emphasizes addressing nutrient gaps. Its website states that around 50% of children worldwide experience nutrient gaps, and the brand positions its products as a way to help close that gap. The company also provides educational resources through its blog and pages covering ingredients, science, heavy metals and pesticides, a 2026 Hidden Health Crisis Report, vanishing nutrients, vitamin overconsumption, and a family nutrient deficiency quiz. First Day offers a subscribe-and-save option for repeat purchases. The website includes an "About Us" page and a "Learn" section with articles, though specific details about the company's founding or headquarters are not provided in the available content.
