Grospire is formulated for children and teens between the ages of 8 and 18 — the window when the growth plates in the long bones are still open and nutrition can still contribute meaningfully to bone development. We don't recommend it for children under 6, and after 18 the growth plates have usually closed and the formula is targeting a window that is no longer there.

Every two-gummy serving delivers vitamin D3, vitamin K2 (MK-7), calcium, zinc, magnesium, L-arginine, L-glutamine, L-carnitine, collagen peptides and turmeric — the pediatric growth-nutrition stack. 15 nutrients total. The full supplement-facts panel is on every bottle and in the product description, with the exact milligram and IU doses.

No, and anyone who tells you a supplement will add inches to your child is lying. What Grospire does is cover the nutritional foundations your child needs during the growth-plate window — the three bone nutrients (D3, K2 and calcium) that 92% of American teens are low on, plus the aminos linked to the natural growth-hormone pulse during deep sleep. Final adult height is still 60-80% genetics. Nutrition is the lever on the other 20-40%.

You can, but you don't need to. Grospire covers vitamin D3, K2, zinc, magnesium and calcium at the levels pediatric nutrition research targets, so a standard kids' multi can become redundant. Check the supplement facts on both bottles before doubling up on anything.

They're mixed-berry flavoured and lightly sweetened with cane sugar (2g per serving — about a quarter of a teaspoon). They taste like a normal gummy vitamin, not like medicine. 94% of the parents in our beta reported their child asking for them without a reminder by week two.

Nutrition is a slow lever. Expect the first changes to be energy, mood during school hours, and quality of sleep — those usually show up in the first three to four weeks. Any change in the growth curve is a 6-12 month read on the pediatrician's chart, not a weekly measurement at home. Save the growth-chart photos and look at them in six months.

Try it for 60 days. If your child won't take it, if you don't like how the first month feels, or if you just change your mind — email us and we'll send you a full refund. No questions, no returns, no "we need to see the bottle". Keep what's left of the bottle.

Every ingredient in Grospire is a food-grade or USP-grade nutrient already used in standard pediatric multivitamins — nothing novel, nothing proprietary, nothing undisclosed. Every batch is third-party tested for identity, potency, heavy metals, pesticides and microbial contamination before it ships. Certificates of analysis are available on request.

No. Every order on this page is a one-time purchase. We don't run a subscription on Grospire and we don't rebill you. If you want more, you come back and order again.
