Most Protein Powders Weren't Made for Kids.
Most protein powders on the market were designed for athletes and adults. That means:
Unsafe ingredients — creatine, caffeine, and artificial sweeteners with no safety data in children
Adult-level doses — protein concentrations far too high for developing bodies
Terrible taste — chalky, artificial flavors kids refuse to drink
Hidden sugars and artificial dyes — used to make bad formulas palatable

What the hiya Fam is Saying
Let's Take Some Questions
Does my child actually need a protein supplement?
It depends on your child's diet. Kids who eat a well-balanced diet with varied protein sources (meat, fish, eggs, dairy, legumes) may get enough protein from food. However, picky eaters, children with food allergies or restrictions, kids in active sports, and those going through growth spurts often have gaps that a supplement can fill.
Is Hiya Protein safe for kids as young as 2?
Yes. Hiya Daily Growth + Protein is formulated for ages 2 to 12. Every ingredient is dosed at levels appropriate for growing children — not scaled down from adult formulas. The product undergoes third-party testing every batch to ensure safety, purity, and compliance with Prop 65.
What does it taste like?
A smooth, creamy sweet cream vanilla flavor. It mixes easily with milk or milk alternatives and doesn't have the chalky aftertaste common in adult protein powders. Sweetened naturally with monk fruit and organic Madagascar vanilla — zero sugar, zero artificial sweeteners.
What makes Hiya different from other kids' protein powders?
Most kids' protein powders are either adult formulas rebranded with cartoon packaging, or basic single-ingredient proteins with little else. Hiya is built as a complete growth shake — grass-fed whey protein plus a targeted amino acid blend, a bone-building mineral blend, organic healthy fats, and prebiotic fiber.
Does it contain dairy?
Yes. Grass-fed whey protein isolate is derived from milk, so Hiya Protein contains milk. It is gluten-free, non-GMO, and free from peanuts and tree nuts. It is not suitable for children with a cow's milk allergy or dairy intolerance.
What is grass-fed whey isolate, and why does it matter?
Grass-fed whey isolate is the purest form of whey protein — processed to remove most of the fat and lactose, leaving a highly concentrated protein. Sourcing from grass-fed cows means a cleaner nutrient profile and less exposure to hormones and antibiotics common in conventional dairy farming.
Why is there fiber in a protein powder?
Because we designed a growth shake, not just a protein shake. Organic inulin (from artichoke) is a prebiotic fiber that feeds beneficial gut bacteria, supporting digestion, nutrient absorption, and immune health. At 4g per serving, it also contributes meaningfully to kids' daily fiber needs.
What if my child doesn't like it?
We stand behind the taste. If your child doesn't love it within the first 10 days, contact us for a full refund — no questions asked.
