Third-Party Lab Tests

Yes. Finished products are tested by independent laboratories, and the report for each product is on this page.

It means a laboratory that is independent of Nutricel tested the finished product. We do not run the tests ourselves, and the lab issues the report.

It depends on the product. Our reports come from Eurofins, NSF and RST Analytical, all independent of Nutricel. The lab's name is at the top of each report.

Yes. Our capsule lab reports include a heavy metals panel covering lead, arsenic, cadmium and mercury. Results are reported in parts per billion (ppb), which is 1,000 times more precise than the parts per million (ppm) scale used by many competitors.

Yes. Microbial testing covers E. coli, Salmonella, Staph aureus, yeast and mold, and total aerobic count.

Yes, in two ways. For Blue Remove, the lab measured the amount of methylene blue against the label claim by titration. For Blue Boost 120 and Blue Shroom, NSF confirmed the methylene blue by matching it to a reference standard.

Compare the result on the report with the limits in the table on this page. Heavy metal limits are the USP daily limits. Microbial results should read Absent or fall under the stated limit.

Not always. A Certificate of Analysis (COA) is a document listing what a product was tested for and the results. A manufacturer can issue one for its own product, and then you are trusting the manufacturer's numbers. A third-party test is run by an independent laboratory with no stake in the result. Some independent labs also title their reports "Certificate of Analysis", so look at who issued it. The lab reports on this page come from independent labs, and the lab's name is at the top of each one.

Right here. This page has reports for Blue Boost 60, Blue Boost 120, Blue Boost Liquid, Blue Immune, Blue Remove, Blue Renew and Blue Shroom.

Each report covers the lot named on it. We do not publish a report for every lot, so your bottle may come from a different lot than the one shown.

Both measure very small amounts. One part per million (ppm) equals 1,000 parts per billion (ppb), so 124 ppb is the same as 0.124 ppm. Our reports use ppb because it is the finer scale.

Nutricel uses USP-grade methylene blue at 99.4% purity. USP (United States Pharmacopeia) grade is the pharmaceutical standard for human consumption, distinct from the lower-grade industrial or aquarium-grade methylene blue sold by many suppliers.

Yes. Nutricel sources USP-grade methylene blue at 99.4% purity, the pharmaceutical standard set by the United States Pharmacopeia. Products are bottled in the USA at a GMP certified facility.

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.
