NuBest Grow Power
NuBest Grow Power
A twice-daily capsule pairing calcium, D3, zinc, and algae-derived DHA for the growing years when diet gaps show up most — school, sports, and picky eating included.
What's In Each Capsule
Straight from the supplement facts panel — the exact amount of every nutrient per capsule. The full daily dose is 2 capsules, so double these for the total. %DV (% Daily Value) shows how much of an adult's recommended daily intake one capsule provides — it's the same reference used on any nutrition label, not something specific to kids' needs.
† Daily Value not established for DHA or GABA. One nutrient worth a second look: Magnesium lands at just 2% DV per capsule — modest for a formula marketed around bone support. Check your own bottle to confirm current amounts, since formulations can be updated over time.
Grow Power is a nutritional-gap filler, not a growth-plate accelerant. 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.
Worth being direct about what this means for height specifically: no supplement lengthens bones beyond what genetics and open growth plates allow. NuBest's own product page says this plainly too — the product isn't intended to treat any disease that causes short stature, and a suspected growth condition warrants a full medical evaluation first. What adequate nutrition can do is remove deficiency as a limiting factor during the years growth plates are still active.
What's Actually Inside
| Ingredient | Amount/Capsule | Role |
|---|---|---|
| Calcium (Tricalcium Phosphate) | 250 mg | Primary structural mineral for bone mass |
| Vitamin D3 (Cholecalciferol) | 10 mcg | Required for calcium and phosphorus absorption in the gut |
| Vitamin B6 (Pyridoxine HCl) | 1 mg | General metabolic and neurological support |
| Phosphorus (Tricalcium Phosphate) | 147 mg | Works alongside calcium in bone mineral structure |
| Magnesium (Amino Acid Chelate) | 10 mg | Bone matrix formation, muscle function |
| Zinc (Zinc Gluconate) | 7.5 mg | Growth-related hormone signaling, collagen formation |
| Sodium (Sodium Chloride) | 15 mg | Electrolyte balance |
| DHA (Algae-derived powder) | 10 mg | Vegan omega-3 for brain and eye development |
| GABA (Gamma-Aminobutyric Acid) | 5 mg | Included for relaxation support |
| Other ingredients | — | Hypromellose (capsule shell), Cassia Bark Extract. Contains Milk, Soy. |
Why It's Worth Considering
Bone-building minerals in one place — calcium, magnesium, phosphorus, and zinc are the core minerals bones actually need.
D3 for absorption — calcium is only as useful as the body's ability to absorb it, and D3 is what makes that possible.
A vegan DHA source — algae-derived DHA directly, without the inefficient conversion problem that comes with flaxseed-based ALA.
Simple, twice-daily routine — two capsules after meals fits easily into a school-day or sports schedule.
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 oral GABA 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 found limited evidence for stress reduction 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. If sleep quality is the actual goal — which matters for growth, since deep sleep is when growth hormone release peaks — a consistent bedtime, a dark cool room, and limiting screens before bed are the more evidence-backed levers, with GABA as a minor supporting factor at most.
A Simple Daily Routine
A Couple of Things Worth Checking
Nothing dramatic here — just the kind of stuff any good pediatrician would want to know:
This product contains milk and soy — a real allergen concern for any child with a diagnosed allergy to either.
If height or growth rate is a specific concern, a full pediatric evaluation should come first — this product isn't positioned as a treatment for any underlying cause of short stature.
Already taking another calcium, zinc, or vitamin D supplement? Total daily intake across all sources is what matters for staying within safe upper limits.
As with all NuBest products, a physician's input is worthwhile before starting, especially given the number of active ingredients combined here.
Questions Parents Usually Ask
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. Works best alongside sleep, activity, and a generally balanced diet, not as a standalone fix.
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, so any child with a milk or soy allergy should avoid this or check with a doctor first.
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.
NuBest recommends at least 6 months of consistent use, which lines up with how bone remodeling actually works — a gradual process, not something that shows up in weeks.
