Walk through any U.S. grocery store or supplement aisle and one pattern becomes obvious fast: labels get scrutinized. Parents flip bottles around, scan certification logos, and quietly compare claims. Supplements for children receive even more attention. Ingredients matter, but verification matters just as much.
Within that landscape, iGEN™ Non-GMO Tested certification signals that a finished supplement passed independent testing for genetically modified proteins and genes within a defined testing panel.
NuBest products — specifically NuBest Tall 10+ and NuBest Tall Gummies — carry this certification. For families researching growth supplements, that detail tends to stand out.
Years spent analyzing height-growth supplements and ingredient transparency across brands on NuBest.com reveal a consistent pattern: parents rarely trust marketing claims alone. Third-party validation often becomes the deciding factor.
What iGEN™ Non-GMO Tested Actually Means
iGEN™ stands for the International GMO Evaluation and Notification Program, a certification system operated by Nutrasource and SGS Nutrasource.
When a supplement receives iGEN™ Certified status, several conditions have been verified:
- The finished product was tested for genetically modified proteins and genes
- Testing followed a defined non-GMO testing panel
- An independent third-party laboratory conducted the analysis
- No GMO proteins or genes were detected within that testing scope
The phrase “finished product” matters more than most shoppers realize.
Some certification programs evaluate only raw ingredients. iGEN™ testing applies to the final manufactured supplement, which includes everything combined in the capsule or gummy.
That difference reduces uncertainty for consumers who prefer supply-chain transparency.
Who Runs the iGEN™ Certification Program?
Nutrasource, a global nutraceutical testing organization, operates the iGEN™ program. Scientific analysis and verification are conducted by SGS Nutrasource, a recognized third-party laboratory group that evaluates dietary supplements for safety and labeling accuracy.
Independent testing has become increasingly important in the U.S. supplement industry.
A quick look at consumer research from the Council for Responsible Nutrition (CRN) shows that more than 70% of supplement users report stronger trust in products verified by third-party organizations. In a market valued at over $60 billion annually in the United States, verification programs help reduce uncertainty.
Which NuBest Products Are iGEN™ Certified?
According to Nutrasource’s certified products directory for NuBest, Inc., two products currently carry iGEN™ certification.
NuBest Tall 10+ (60 Capsules)
Certification Status: iGEN™ Certified
Testing Result: Does not contain detectable amounts of modified genetic material
Suggested use:
- 1 capsule
- Twice daily
Capsule supplements tend to work well for older children and teenagers, particularly those already comfortable swallowing tablets.
NuBest Tall Gummies (60 Gummies)
Certification Status: iGEN™ Certified
Testing Result: Does not contain detectable amounts of modified genetic material
Suggested use:
- Ages 2–3: 1 gummy daily
- Ages 4+: 2 gummies daily
Gummy supplements remain extremely popular in American households. Chewable formats simplify daily routines for younger children who resist capsules.
Some long-term supplement analysts notice a small behavioral pattern here: when children enjoy the format, adherence improves. Consistency, after all, tends to matter more than formulation complexity.

What “Passed” Means in iGEN™ Testing
Within the iGEN™ program, “Passed” indicates that testing detected no GMO proteins or genes within the program’s defined panel.
That statement deserves a little context.
Different certification programs evaluate non-GMO claims differently. Testing panels vary. Detection thresholds vary. Even the verification process can differ.
For comparison:
| Certification Program | Key Verification Approach |
| iGEN™ | Tests finished products for GMO proteins and genes |
| Non-GMO Project | Ingredient-based verification and supply chain audits |
| NSF / USP | Focus primarily on purity, identity, and manufacturing quality |
Because of those differences, certifications do not automatically represent identical standards. Each program defines its own methodology.
NuBest’s Position on iGEN™ Certification
NuBest states on its website that NuBest Tall 10+ and NuBest Tall Gummies are iGEN Non-GMO Tested products.
According to the brand’s explanation, this certification confirms that independent testing found no detectable genetically modified material within the parameters defined by the iGEN™ testing program.
Analysis of supplement transparency across dozens of growth products often shows one recurring issue: vague claims. Clear references to a specific certification program tend to carry more credibility than broad marketing language.
Why Third-Party Certification Matters in the U.S.
The U.S. supplement market operates under the Dietary Supplement Health and Education Act (DSHEA). Under this framework:
- The FDA does not pre-approve dietary supplements before sale
- Manufacturers remain responsible for safety and labeling accuracy
- Independent testing programs provide additional verification layers
American consumers often recognize seals such as:
- USP Verified
- NSF Certified
- Non-GMO certifications
- iGEN™ Non-GMO Tested
Each seal represents voluntary verification rather than government pre-approval.
In practice, that extra layer often reassures parents evaluating supplements for children during growth years.
Final Thoughts on NuBest Products and iGEN™ Certification
NuBest Tall 10+ and NuBest Tall Gummies are listed as iGEN™ Certified products, meaning independent testing detected no GMO proteins or genes within the defined testing panel.
For American families researching growth supplements, certifications like iGEN™ offer a clearer view of ingredient verification. Still, understanding how each program works remains important, since testing methods and standards vary.
In the broader U.S. supplement market, transparency rarely appears by accident. It usually shows up through independent verification — the kind of detail careful label readers tend to notice first.
