Children's supplements are one of the strongest-growing private-label categories and, without question, the most heavily scrutinised. Almost every difficulty in this category comes from the same source: a child is not a small adult. The dose, the format, the texture, the flavour and the permitted wording all change. This guide covers what actually has to be decided, and the points where brands most often have to go back and reformulate.

Start with the format, because children limit it

  • Gummies — the dominant format and the easiest sell. Parent-friendly, child-accepted, and the format most buyers ask for first. The trade-offs are real: a gummy carries a limited active load, and texture has to stay soft enough to chew safely.
  • Chewable tablets — a higher active load than gummies at a lower cost, and a common choice for multivitamins. They need a genuinely pleasant chew, not a chalky one.
  • Liquid drops and syrups — the practical choice for the youngest age bands, where dosing is by dropper or spoon and swallowing is not yet reliable.
  • Powders and stick packs — good for stirring into milk, yoghurt or a drink, and the easiest way to deliver a larger dose without asking a child to chew anything.
  • Capsules — rare in this category for an obvious reason: most children cannot or will not swallow them.

Actives, and where the real formulation problems sit

  • Multivitamin bases — the backbone of the category. Keep the levels appropriate to the age band rather than scaling an adult formula down or up.
  • Omega-3 and DHA — one of the most requested kids' actives. Taste and oxidation are the hard part: marine oil goes rancid and fishy quickly unless the formula and the pack are built for it, and algal oil is the usual route to a vegan claim.
  • Vitamin D and zinc — both common, both require care with taste. Zinc in particular has a metallic note that has to be masked, not just sweetened.
  • Iron — effective and widely used, but the ingredient that demands the most respect in a children's product. Overdose in young children is a genuine safety matter, which is why the pack warning and the child-resistant closure are formulation decisions, not packaging afterthoughts.
  • Probiotics and magnesium — increasingly requested. For probiotics, the CFU count at end of shelf life and the moisture barrier are what determine whether the product holds up.

Taste, sugar and texture

Three constraints shape every children's formula. First, sugar: parents read the panel, so low-sugar and sugar-free versions are increasingly the default, and a sugar-free gummy means a pectin base and a different texture from a gelatine gummy. Second, taste masking: the actives that matter most in this category — fish oil, zinc, iron, some botanicals — are also the hardest to hide, and masking has to be designed into the formula rather than added at the end. Third, texture: the gummy has to be soft and chewable for the intended age band, which limits how much active can be pushed into each piece.

Age bands and dose statements

A children's product needs a clear age band and a serving size tied to it, and it should not be possible for a parent to read the label and give a double dose by mistake. In practice, different age bands often mean different serving sizes, and sometimes a different format altogether — which is why many brands launch a drops version for the youngest band alongside a gummy for older children.

Where the claim wording stops

  • A supplement may describe its effect on normal structure or function; it may not claim to diagnose, cure, treat or prevent a disease. This applies to children's products exactly as it applies to adult ones.
  • Claims that are marginal for adults — growth, height, brain development, attention, resistance to infection — are considerably more restricted for children, and in several markets are not permitted at all.
  • Avoid disease-adjacent terms entirely on a children's pack, and keep the label itself to the product name, specification and count.
  • Check the market before you design artwork: several markets restrict specific actives for the youngest age bands, and some restrict gummy formats for very young children on choking grounds.

Packaging and MOQ

Wide-mouth jars suit gummies, blister or bottle suits chewables, dropper bottles suit liquids, and stick packs suit powders. Where a market requires a child-resistant closure or a specific warning statement, that requirement has to be known before the pack is tooled. A practical starting point with a manufacturer that supports small batches is MOQ 500 units per SKU, samples in 3–5 days, production shipped within 7 days, and a certificate of analysis with every batch.
