Four new children’s supplements worth knowing about

A shift is taking place on the children's supplements shelf. Sugar-laden multivitamins are giving way to cleaner formulations, condition-specific probiotics, and chocolate flavoured greens that even picky eaters will reach for. Four new launches; one British, one founded by a leading gut health doctor, one freshly arrived from the US, and Capychews, the brand set to become a fixture in family medicine cabinets. These are the ones to know about right now. Find out more below..

1. Tonic Health

Tonic Health is the homegrown wellness brand whose Kids Multivitamin Gummies have become one of the cleanest formulations on the high street. Fourteen vitamins and minerals; A, C, D, E, the full B complex and Zinc among them are delivered in a strawberry-flavoured gummy made without added sugar, sweeteners or anything resembling the synthetic colourings still surprisingly common in the category. They are vegan, non-GMO, and developed for children aged 3 to 12. What sets Tonic apart is the discipline of the formulation. Rather than dialling up the marketing flourishes, the brand has stripped its ingredients list back to what actually does the work, which means a parent reading the back of the pack does not have to translate. The strawberry colour comes from black carrot concentrate; the sweetness from beetroot fibre. It is the kind of considered formulation that makes a daily multivitamin feel less like a compromise and more like a sensible piece of the routine. Available at Boots, Tesco, Sainsbury’s, Ocado and Amazon UK, with a probiotic blackcurrant gummy now joining the line up among other options in the range.

2. SMART STRAINS by Dr Megan Rossi

Launched in February 2025 by gut-health doctor and dietitian Dr Megan Rossi (the founder behind Bio & Me) - SMART STRAINS is the most clinically rigorous probiotic launch the family-health shelf has seen in years. The proposition is refreshingly precise: rather than a daily probiotic taken indefinitely, the range offers four condition-specific formulations to be used only when needed, each built around the live bacterial strains the international guidelines actually back. The most interesting one for families is For Fussy Babies, an 8ml drop containing Bifidobacterium lactis BB-12 - a strain recommended by the World Gastroenterology Organisation and leading paediatric guidelines, with clinical evidence behind its use in colic and early gastrointestinal discomfort. For older children, the For Your Immune System sachets (containing the most-studied Lactobacillus strain in the world, LGG) are a good option during the school-bug winter months. A serious, science-led product range that respects the parent reading the box. Available at smartstrains.com, Amazon UK, Ocado and Tesco pharmacies.

3. Hiya

Hiya is the American children’s supplement brand that built a quiet cult following in the US for refusing to play the sugar-and-dyes game, and which has just landed in the UK as its first international expansion. The proposition begins with the Kids Daily Multivitamin: a chewable for ages 2 and up, packed with fifteen essential vitamins and minerals plus a fruit and vegetable blend, with zero grams of added sugar. What is interesting is the second product, Kids Daily Greens & Superfoods, a chocolate-flavoured powder built to be stirred into milk, framing the daily greens habit as a familiar chocolate-milk ritual. For a parent battling a fussy eater across breakfast, the trick is hard to argue with.
