The HappyGrow formula
Everything a growing body needs, in two gummies a day
Ten vitamins and minerals plus our HappyGrow® blend — built around the nutrients kids most often miss during the years that shape how they grow.
Calcium is the mineral bones are made of — but it only gets there with help. Vitamin D3 helps the body absorb it, K2 helps direct it into bone, and magnesium holds the structure together. We include all four, together, on purpose.

School, sports, playdates — kids meet a lot of germs. Vitamin C, zinc and vitamin D3 each play a documented role in normal immune function, at levels sized for a child rather than a scaled-down adult dose.

B vitamins are how the body converts breakfast into the energy to get through the day. Iodine supports the thyroid hormones that regulate growth and focus — one of the most commonly overlooked nutrients in a child's diet.

Star-shaped, watermelon-flavoured, and soft enough for a four-year-old to chew. The best formula in the world does nothing if it stays in the cupboard — so we made the part kids care about just as carefully as the part you do.

Parent questions
The questions we get most often
Straight answers, including the ones that aren't a sales pitch.
No supplement can promise height, and we won't pretend otherwise. Most of how tall your child grows is set by genetics.
What nutrition controls is whether their body has what it needs to reach the height it's already headed for. A child missing calcium, vitamin D or zinc during the growing years can fall short of their own potential — and that part is fixable.
HappyGrow is built to close those gaps. It's daily nutrition, not a growth treatment.
HappyGrow is formulated for ages 4 and up. Every nutrient sits at a level appropriate for a child — not an adult dose cut in half — and no single nutrient exceeds 100% of a child's Daily Value.
Every batch is third-party lab tested before it ships. The gummies are soft and star-shaped, but as with any chewable, children should be seated and supervised while eating.
If your child takes medication, has a medical condition, or has known allergies, check with your pediatrician first.
4 grams per serving of two gummies — about a teaspoon, and less than you'll find in most children's yogurts.
We'd rather be straight about that than hide it. A gummy needs some sugar to taste like something a child will actually ask for, and a supplement your child refuses is worth nothing at all.
The full breakdown is on our Supplement Facts panel.
Two gummies a day, any time. One bottle of 60 lasts a full month.
Many parents pair them with breakfast simply because it's easier to remember — and the fat in a normal meal helps with vitamins D3 and K2. They don't need to be taken with food, though.
Missed a day? Just carry on the next day. Don't double up.
Then you get your money back. You have 30 days, you keep the bottle, and there's no return shipping — one email is all it takes.
They're watermelon-flavoured and shaped like stars, which wins over most picky eaters. But every child is different, and we'd rather refund you than have a bottle sitting unopened in your cupboard.
Honestly? Nutrition isn't something you feel working. Any brand giving you a countdown to visible results is guessing.
Filling a nutrient gap is slow, quiet work — the kind you'd only see on a growth chart over many months, and only if a gap was there to begin with. Growth in children is measured over years, not weeks.
What we'd suggest instead: track height at your regular pediatric check-ups, and treat this the way you'd treat a good breakfast — consistently, without expecting a moment.

No — and no supplement is. The FDA doesn't approve dietary supplements the way it approves medicines. Any brand claiming to be "FDA approved" is either confused or misleading you.
