NuBest Grow Power
What This Product Is Actually For
Grow Power is a nutritional-gap filler, not a growth-plate accelerant. Its core logic is straightforward: growing teenagers have higher requirements for bone-building minerals than a typical daily diet reliably provides, especially once school schedules, sports, and picky eating start crowding out balanced meals. The formula supplies calcium, magnesium, phosphorus, and zinc — the core minerals bones are built from — alongside vitamin D3, which is required for the body to actually absorb and use that calcium.
It's worth being direct about what this means for height specifically: no supplement can lengthen bones beyond what genetics and open growth plates allow. What adequate nutrition can do is remove nutritional deficiency as a limiting factor, so a child's growth isn't held back by gaps in calcium, vitamin D, or zinc intake during the years growth plates are still active.
Straight from the label: NuBest's own product page states this plainly: the product is not intended to diagnose, treat, cure, or prevent any disease that causes short stature, and any child with a suspected growth or short-stature condition should get a full medical evaluation before starting a supplement. That's a meaningful, honest disclosure worth taking seriously rather than skipping past.
What's Actually Inside
| Ingredient | Form | Role |
|---|---|---|
| Calcium | Tricalcium Phosphate | Primary structural mineral for bone mass; label states 250 mg per serving |
| Vitamin D3 | Cholecalciferol | Required for calcium and phosphorus absorption in the gut |
| Magnesium | Magnesium Amino Acid Chelate | Supports bone matrix formation and muscle function |
| Phosphorus | Dicalcium Phosphate | Works alongside calcium in bone mineral structure |
| Zinc | Zinc Gluconate | Involved in growth-related hormone signaling and collagen formation |
| Vitamin B6 | Pyridoxine HCl | General metabolic and neurological support |
| DHA | Algae-derived powder | A vegan source of the omega-3 fat most studied for brain and eye development |
| GABA | Gamma-Aminobutyric Acid | Included for relaxation support (see honest science note below) |
| Other ingredients | Hypromellose (vegetarian capsule shell), Cassia Bark Extract | Capsule structure and flavor/minor botanical addition |
Only one exact dose is published. NuBest's public materials disclose the calcium content (250 mg per serving) but don't publish exact milligram amounts for magnesium, phosphorus, zinc, vitamin D3, B6, DHA, or GABA. If precise dosing matters to you — for example, checking totals against your child's other supplements — the full supplement facts panel on the physical bottle is the source to check, not the marketing page.
Key Benefits at a Glance
An Honest Note on GABA
GABA is included here for relaxation support, and it's worth understanding what the evidence actually shows before expecting a specific effect. GABA is the brain's main inhibitory neurotransmitter — but GABA taken orally has long been questioned on one key point: whether it can cross the blood-brain barrier in meaningful amounts to directly affect brain activity. A 2020 systematic review of oral GABA trials in humans found limited evidence for stress-reduction effects and very limited evidence for sleep benefits, with the underlying mechanism still scientifically unresolved.
What this means in practice: GABA isn't a proven sleep aid the way melatonin has been studied, and it shouldn't be relied on as one. If sleep quality is the actual goal — which matters for growth, since deep sleep is when growth hormone release peaks — the more evidence-backed levers are a consistent bedtime, a dark and cool room, and limiting screens before bed, with GABA (if included at all) as a minor supporting factor rather than the main plan.
How to Use It
Ages 10+
Take 1 capsule twice daily after meals — nutrients are generally better absorbed with food.
Timing
NuBest recommends taking both doses earlier in the day (after breakfast and lunch), not close to bedtime.
Commit to months, not days
NuBest's own guidance — echoed by their medical advisor — recommends at least 6 months of consistent use to judge results, alongside diet, activity, and sleep.
Who Should Check With a Doctor First
Frequently Asked Questions
Will this make my child taller?
It can support the nutritional side of growth — calcium, vitamin D, and zinc adequacy — but it can't override genetics or reopen closed growth plates. Nutrition support works best alongside sleep, activity, and a generally balanced diet, not as a standalone fix.
Why does it contain milk and soy if it's meant for kids?
These likely come from the specific mineral or DHA forms used in manufacturing rather than being added as separate ingredients, but they're still disclosed allergens — any child with a milk or soy allergy should avoid this product or check with a doctor first.
Is the DHA here better than flaxseed-based omega-3?
For brain and eye health specifically, yes — this formula uses DHA directly from algae, avoiding the inefficient conversion problem that comes with flaxseed-based ALA products.
How long before we'd see a difference?
NuBest recommends at least 6 months of consistent use, which lines up with how bone remodeling actually works — it's a gradual process, not something that shows up in weeks.
