What we couldn't verify

We did not visit this company on site. See the limits that apply to every listing.

• NSF GMP registration (NSF/ANSI 173 Section 8) is confirmed for the China-based manufacturing entities (Jiangyin and Xuzhou, Jiangsu); ingredients are manufactured in China with US commercial operations in Missoula, Montana, so buyers should confirm country-of-origin documentation per order
• The corporate structure spans China manufacturing and North American offices; confirm the contracting and shipping entity per purchase
