Teach Height.

Yes. Height is polygenic — controlled by thousands of gene variants, each contributing tiny amounts. But genes set a range, not a fixed number. The environment determines where in that range your child lands.

A 24-week study of short-stature children found that a jumping protocol produced +4.32 cm of height gain vs 0.93–1.84 cm in controls. IGF-1 increased. Bone density improved. Zero injuries.

Every recommendation in this app is cited to an academic or scientific study published in a scientific journal. We don't guess. We read 2,400+ hours of research and built a daily system from it.

Birth through age 25. Your body keeps growing longer than most people think.

Growth plates in males commonly remain open into the early 20s. Many 18, 19, and 20-year-olds still have active growth plates and are still gaining height — especially with the right inputs. Even after plates close, bone mass (density, thickness, and vertebral structure) continues increasing until your mid-20s. This adds measurable height. You reach peak bone mass around age 25 — and every bit of density you build before that point becomes your foundation for life.

The earlier you start, the more years of compounding you get. But starting at 16, 18, or even 22 still gives you years of real, meaningful optimization during the window that matters most.

It starts with the standard mid-parental height prediction used by pediatric endocrinologists worldwide — your height plus your partner's height, adjusted for your child's sex, with a ±2" genetic range. The “genetic range” comes directly from this method.

Then it shows the bioKids zone — where your child could land with optimized sleep, nutrition, and physical activity during the growth window. This isn't a guarantee. It's the ceiling that the science supports when every lever is pulled consistently.

Life happens. Even 60% consistency compounds beautifully over months. A pizza night or a late sleepover doesn't erase a week of good inputs.

The protocol is designed around real family life. The daily targets matter more than perfection on any single day. Miss something? Pick it up tomorrow. Your child's growth axis responds to patterns, not individual meals.

We even give an optional detox smoothie to help the body excrete these foods without issues.

Every study is available at the US National Library of Medicine via PubMed (National Center for Biotechnology Information). Every recommendation links directly to its source — journals like JAMA, Lancet, JCEM, Nature, and the Journal of Applied Physiology. Every number on every card cites the study it comes from.

Some studies are from human adults, supplements, and some from animals (marked with *). We note this transparently. Whole foods deliver these pathways at lower but meaningful levels — for example, a-GPC was shown in a study to increase growth hormone by 44×, whereas acetylcholine from eggs would hit that same pathway in a lesser but significant way. We do not overstate what the research shows — but we do show you that research.

No. Every growth signal — sleep quality, nutrient density, sprint-triggered hormones — simultaneously supports brain development, bone density, and long-term health. The same pathways that drive height drive cognitive function and skeletal strength. You're not choosing between height and health. They're the same system.

And the benefits extend well beyond childhood. Peak bone mass is reached around age 25. The calcium, vitamin D, protein, and impact exercise your child gets now is literally building the bone bank they'll carry for the rest of their life. A stronger peak means stronger bones at 40, 60, and 80.

You are giving your child the best chance to maximize their genetic expression — from birth through their mid-20s.
