About Hiya Health

Hiya Health is a children's vitamin company co-founded by Darren Litt and Adam Gillman, who say they started it as new fathers after looking into what went into kids' vitamins. USANA Health Sciences bought a 78.8% controlling stake in a $205 million cash acquisition completed on 23 December 2024. Its British storefront lists a separate UK range priced in pounds. What Hiya Health sells Kids Daily Multivitamin, a chewable that Hiya says contains 15 essential vitamins and minerals with no added sugar and no gummy base Kids Daily Biotic+ and Kids Daily Iron+, each sold by the bottle on the UK store Kids Daily Greens + Superfoods, a chocolate-flavoured greens blend sold by the canister On the American store only: a teen multivitamin plus bedtime, hydration, fibre, protein and immune products Hiya states that its formulas are made for children aged 3 to 12, developed with paediatricians and nutritionists, sweetened with mannitol and free from the top nine allergens. These are the brand's own statements, and its product pages carry the notice that they have not been evaluated by the US Food and Drug Administration. Delivery and returns Hiya's UK shipping and returns page says customers pay nothing for delivery, and the company aims to send products within 3 to 5 business days using carriers such as Royal Mail, Evri, DPD or DHL.
