How We Test
Three Independent Verification Layers
Most supplement brands stop at the bare minimum. We run three separate checks before a product reaches you.
1
NSF-Registered, GMP-Certified Manufacturing
Every product is made in an NSF-registered, GMP-certified facility where batch testing is required before release. This is the industry baseline.
2
Independent Pre-Encapsulation Testing
Unlike most brands, our manufacturer uses a separate independent lab to test raw materials and blends before encapsulation, verifying material quality before the capsule is even made.
3
Finished-Product Verification
After bottling, finished products are verified two ways: Eurofins, one of the world's largest ISO/IEC 17025-accredited independent labs, confirms heavy metals and microbial safety, and methylene blue content is verified against the label claim. These are the reports you can download above.
Reading The Numbers
How to Read Our Lab Results
Each COA confirms product safety, purity, and content accuracy. Every panel below passed with results well below industry limits.
Microbial Safety
- E. coli: Absent (none detected)
- Salmonella: Absent (none detected)
- Staph aureus: Absent (none detected)
- Yeast & Mold: well below the 1,000 CFU/g limit
- Total aerobic count: well below USP limits
Heavy Metals (USP daily limits)
- Lead: 10 mcg/day or less
- Arsenic: 15 mcg/day or less
- Cadmium: 4.1 mcg/day or less
- Mercury: 2 mcg/day or less
Why our reports show ppb, not ppm: Our heavy-metal results are listed in parts per billion (ppb), which is 1,000x more precise than the parts per million (ppm) many competitors use. A larger ppb number is not a red flag. It is simply a finer measuring scale.
Example: A 0.5 g capsule with 124 ppb lead works out to 124 x 0.5 / 1,000 = 0.062 mcg per capsule, just 0.62% of the 10 mcg/day USP daily limit.
Suitability tests are also included to confirm the capsule form does not interfere with detection, so the results are reliable and not masked by the delivery format.
Why It Matters
What Third-Party Testing Proves
An independent, unbiased lab evaluates our products with no involvement from us, confirming three things on every batch.
Purity
No harmful contaminants. Heavy metals and microbes are tested and confirmed below safety thresholds.
Potency
Methylene blue content is verified by titration assay against the label claim on our core formulas, so you get what the label says.
Safety
Products are confirmed safe for consumption and free from substances that have no business being in a supplement.
Raw Material Quality
Why We Use USP-Grade 99.4% Methylene Blue
Quality starts with raw materials. We use the pharmaceutical standard, not the industrial grade sold by most suppliers.
USP Grade
USP (United States Pharmacopeia) is an independent non-profit that sets strict pharmaceutical-grade quality, purity, and potency standards. USP-grade methylene blue is manufactured under guidelines that confirm it is suitable for human use.
99.4% Purity
Most methylene blue on the market is lower-purity industrial or lab-grade material that can carry trace heavy metals or other contaminants. 99.4% purity means virtually nothing else is in the compound.
Why It Matters
Impurities in lower-grade versions can reduce efficacy and pose health risks. We source USP-grade material specifically because we will not cut corners on the primary active ingredient.
Questions
Frequently Asked Questions
Is Nutricel methylene blue third-party tested?
Yes. Nutricel products undergo three independent verification layers: raw material testing before encapsulation, batch testing at an NSF-registered, GMP-certified manufacturing facility, and post-bottling Certificate of Analysis testing by Eurofins, one of the world's largest ISO/IEC 17025-accredited independent laboratories.
What lab tests Nutricel supplements?
Nutricel uses Eurofins, an ISO/IEC 17025-accredited independent laboratory, for post-bottling verification of heavy metals and microbial safety. Methylene blue content is confirmed separately by titration assay. COA PDFs are publicly available for download on this page.
What purity is Nutricel's methylene blue?
Nutricel uses USP-grade methylene blue at 99.4% purity. USP (United States Pharmacopeia) grade is the pharmaceutical standard for human consumption, distinct from lower-grade industrial or aquarium-grade methylene blue sold by many suppliers.
Does Nutricel test for heavy metals?
Yes. Every Eurofins COA includes a full heavy metals panel covering lead, arsenic, cadmium, and mercury. All results are comfortably below USP daily limits. Results are reported in parts per billion (ppb), which is 1,000x more precise than the parts per million (ppm) scale used by many competitors.
Is the methylene blue content verified?
Yes. Methylene blue content is confirmed by titration assay against the label claim on our core formulas, Blue Boost and Blue Remove. Heavy metals and microbial safety are verified on every product by Eurofins.
What is the difference between USP grade and industrial grade methylene blue?
USP-grade methylene blue meets pharmaceutical purity standards set by the United States Pharmacopeia and is manufactured under guidelines confirming it is suitable for human use. Industrial or lab-grade methylene blue is lower purity and may contain trace heavy metals or other contaminants. Nutricel uses only USP-grade methylene blue at 99.4% purity.
Does Nutricel test for microbial contamination?
Yes. Eurofins microbial safety testing covers E. coli (absent), Salmonella (absent), Staph aureus (absent), yeast and mold, and total aerobic microbial count, with all results well below USP limits.
