NuBest Tall Growth Protein Powder
NuBest Tall Growth Protein Powder
A daily protein shake for picky eaters, available in whey-based Chocolate and fully vegan Vanilla — with a rare feature for this category: an actual registered clinical trial behind it.
Chocolate vs. Vanilla — Real Differences at a Glance
These aren't just two flavors of the same thing. Here's what actually changes between them.
| Chocolate | Vanilla | |
|---|---|---|
| Protein source | Whey + Milk Protein Concentrate | Pea + Rice Protein (vegan) |
| Diet | Not vegan or dairy-free | Fully vegan |
| Age range | 3+ (½ scoop at 3–4) | 4+ (½ scoop at 3, full at 4+) |
| Servings/tub | 15 | 10 |
| Allergens | Contains Milk | None of the major allergens |
| Sweetener | Cane sugar + stevia + sucralose | Cane sugar + stevia |
If dairy or a vegan diet matters for your family, Vanilla is the clear pick. Otherwise, it mostly comes down to taste and how many servings you want per tub.
Protein is a genuinely common gap for picky-eater kids — not because meat and dairy don't exist, but because getting a growing child to eat enough of them consistently is a real, everyday challenge. A shake format solves a practical problem: it's an easy way to add protein, calcium, and a broad set of vitamins into a routine a child will actually stick to.
Beyond protein, both flavors layer in calcium and magnesium from Aquamin™ (a marine algae mineral complex), Vitamin D3 and K2, and the DE111® probiotic strain — genuinely researched additions, not just filler.
What's in Both Flavors
| Ingredient | Form | Role |
|---|---|---|
| Calcium & Magnesium | Aquamin™ (marine algae complex) | Bone mineral support — plant-based source with real research behind it |
| Vitamin D3, K2 | Cholecalciferol, Menaquinone-7 | Calcium absorption; K2 directs it toward bone |
| Full B-Complex | Various forms | Energy metabolism |
| Iron, Zinc, Selenium, Copper | Various mineral forms | Immune function, oxygen transport, antioxidant support |
| Organic Flax Seed Powder | Omega 3-6-9 (ALA) | Essential fatty acids |
| L-Taurine, L-Arginine, Inositol Hexanicotinate | Amino acids / compounds | Included for growth-support properties (see note below) |
| Bacillus subtilis DE111® | 1 Billion CFU probiotic | Digestive comfort — genuine pediatric trial data |
| Eucommia Bark Extract | Traditional herbal extract | Traditionally used for bone and joint support |
Good to know: neither flavor is sugar-free — both use a small amount of Organic Evaporated Cane Sugar alongside stevia (Chocolate adds sucralose too, landing at just 2g added sugar per serving). Reasonable for a treat-like shake, but worth factoring into a child's total daily sugar if they're also using NuBest's sugar-containing gummy lines.
The Clinical Trial: What It Actually Shows
This is worth walking through carefully, since it's the product's headline claim. NuBest sponsored a real, registered clinical trial — NCT06704178, a 6-month, randomized, double-blind, placebo-controlled study — comparing this protein powder against a placebo in children. The trial's existence and registration are genuine and verifiable on ClinicalTrials.gov.
Where care is needed is in how results get communicated. NuBest's own published summary reports outcomes largely as parent-reported survey percentages — figures like "88% of parents would recommend it." A claim that the study "significantly improved children's height growth" is a stronger, more specific statement than a recommendation percentage, and it isn't clear from the publicly available summary whether that height claim rests on independently measured, statistically analyzed data or the same parent-reported questionnaires.
What this means in practice: a registered RCT behind a kids' protein shake is a genuine point in this product's favor — most competitors have nothing comparable. But "clinically tested" and "significantly improved height growth" are two different claims, and only the first is unambiguously supported by what's publicly available.
Why It's Worth Considering
A probiotic strain with real pediatric data — DE111® has an actual randomized trial in preschool-aged children, not just adults.
Aquamin calcium and magnesium — a marine-algae mineral complex with a genuine, multi-decade research base in bone health.
D3 and K2, paired correctly — K2 helps direct absorbed calcium toward bone rather than soft tissue.
A flavor and diet option for most families — whey-based Chocolate or fully vegan Vanilla, so allergy or diet preference isn't a dealbreaker.
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:
Milk allergy or lactose intolerance in the family? Chocolate contains whey and milk protein — Vanilla is the dairy-free pick.
Already on another NuBest calcium, D3, or K2 product? Check total daily intake across everything your child takes.
Tracking sugar or artificial sweetener intake? Both flavors contain real sugar and stevia; Chocolate adds sucralose too.
As with any daily supplement, a heads-up to your pediatrician is worthwhile, especially alongside other vitamins.
Questions Parents Usually Ask
If dairy or a vegan diet matters, Vanilla is the clear choice. Otherwise it comes down to taste and how many servings you want per tub (15 for Chocolate, 10 for Vanilla).
NuBest specifically advises against it — Vitamins A, B, C, and Calcium are heat-sensitive and lose effectiveness above 212°F. No-bake recipes like energy bites or overnight oats work instead.
Yes — NCT06704178 is a real, registered randomized controlled trial. Worth double-checking whether specific claims like "significantly improved height growth" come from objectively measured data or the same parent-reported survey used for other reported percentages.
Milk, smoothies, or yogurt all work well — a good way to turn it into a more substantial snack rather than just a drink.
