90-Day Growth Guarantee
Track your child's growth over 90 days. If you don't see measurable height increase on the growth chart—if the K2 mechanism doesn't make the calcium they're already getting actually work—we'll refund every penny. No questions asked.
Why didn't milk and multivitamins work?
+
Up to 80% of dietary calcium never reaches the bones. Without Vitamin K2 activating osteocalcin, calcium has no 'GPS'—it just circulates in the bloodstream unused. Your child was probably getting enough calcium. It just wasn't getting DIRECTED to where it needed to go.
How is Grow Spark different from TruHeight or NuBest?
+
Most supplements focus on adding MORE calcium and vitamins (input). Grow Spark focuses on DIRECTING existing calcium to bones through K2-activated osteocalcin, plus activating IGF-1 growth signals through HT042. Different mechanism entirely—not more materials, better activation.
My child eats well and sleeps—why isn't he growing?
+
You can have all the building materials (calcium, protein, vitamins) but if the growth SIGNAL isn't firing, materials sit unused. IGF-1 is the 'foreman' telling growth plates to build. HT042 has been clinically shown to increase IGF-1 levels in children below the 10th percentile.
When will I see results?
+
Most parents notice measurable growth around week 4-8. Mark the wall every Sunday. Track percentiles at checkups. The growth chart doesn't lie. Clinical studies on HT042 showed 0.45 cm additional gain over 24 weeks beyond baseline.
Is this safe for my child?
+
Grow Spark contains clinically-studied ingredients at safe, effective doses: Vitamin D3, K2 (MK-7), bioavailable Zinc Picolinate and Magnesium Bisglycinate, HT042, Bovine Colostrum, Alpha-GPC, and Glycine. All are well-tolerated and extensively researched for children.

Week 4 the pediatrician measured him twice. 'Has something changed?' she asked. He'd grown 0.7 inches in one month. After six months of barely moving, the growth chart finally curved upward. - Verified Customer
"I tried everything you're trying. Three glasses of milk a day. Protein smoothies. Basketball. Expensive supplements. Six months, $800 spent. The growth chart barely moved. Then I learned why everything failed the same way."
Why Milk And Vitamins Haven't Worked
Up to 80% of dietary calcium never reaches the bones.
Your child is drinking milk. Eating calcium-rich foods. Maybe even taking supplements. But without Vitamin K2 activating osteocalcin, calcium doesn't know WHERE to go in the body.
It's like packages sitting in a delivery truck that never gets an address. The calcium is THERE. It's just not getting DIRECTED to the bones.
That's why you can give your child all the milk in the world and still see minimal growth. The calcium has no GPS.
🎯
K2 Activates Osteocalcin
The protein that literally "grabs" calcium from bloodstream and deposits it into growing bones.
⚡
Children Need 8-10x More
Growing bones require massive amounts of osteocalcin activation—far more than adults.
🔬
HT042 Activates IGF-1
Clinical trials showed 0.45 cm additional gain in children below 10th percentile—activation, not just nutrition.
🌱
Breaks the Picky Eater Cycle
Zinc Picolinate stops the deficiency loop—43% higher picky eating in zinc-deficient children.
Why Grow Spark Works Differently
Every other supplement I'd tried had the same formula: Add more calcium, add more D3, add more zinc. Increase the input and hope for output.
Grow Spark doesn't work that way.
It contains MK-7—the most bioavailable form of Vitamin K2—at therapeutic doses. Combined with D3 to optimize the calcium-direction system.
It doesn't ADD more calcium to your child's diet. It ACTIVATES the osteocalcin that directs existing calcium into the bones.
Plus HT042 (Astragalus) to activate IGF-1 growth signals. Alpha-GPC for growth hormone support. Bovine Colostrum with growth factors. All in bioavailable forms your child can actually use.

"Spent over $800 on TruHeight, NuBest, and PediaSure. Nothing moved the needle. Three months on Grow Spark and he grew 2.1 inches. From 8th percentile to 23rd percentile. The difference is the mechanism."
✓ Verified Purchase★★★★★
"My son is a picky eater. Turns out zinc deficiency causes picky eating—vicious cycle. The Zinc Picolinate in this actually helped his appetite AND his growth. Two birds, one stone."
✓ Verified Purchase★★★★★
"He's 14. I was running out of time before growth plates closed. Started Grow Spark in March. By June he'd grown 3.1 inches. The pediatrician couldn't believe it. Neither could I."

Track your child's growth for 90 days. Mark the wall every Sunday. Watch the growth chart at checkups. If you don't see measurable height increase—if the K2 mechanism doesn't make the calcium they're already getting actually work—return it for a full refund. No questions asked. You risk nothing.
