Where are our standards?
Not all supplements are created equal. Here's what the certifications and testing actually mean, and other important-to-know terms.
GMP Certified (Good Manufacturing Practices)
FDA-regulated standards for pharmaceutical-grade facilities. Means the facility follows strict protocols for cleanliness, testing, and quality control at every stage of production.
Third-Party Tested
An independent lab (not the manufacturer) verifies what's actually in the bottle matches the label. Tests for purity, potency, contaminants, and heavy metals.
Bioavailable Forms
The chemical form of a nutrient that your body can actually absorb and use. Example: Magnesium glycinate vs. magnesium oxide (glycinate absorbs 4x better).
Non-GMO Project Verified
Certifies that ingredients aren't genetically modified. This is about ingredient sourcing philosophy, not quality or effectiveness.
NSF Certified (NSF International)
Independent third-party organization that tests supplements for content accuracy, contamination, and label claims. NSF Certified for Sport specifically tests for banned athletic substances.
UL Certified
Primarily known for electrical safety, UL also certifies dietary supplements for ingredient verification and label accuracy through UL's Supplement Certification Program.
