Manufacturer statement
NOW Foods’ COA portal states generally that “Strength Testing” guarantees the product contains exactly what is on the label, and that NOW uses a science-based program to test raw materials and finished products for microbial and heavy metals contaminants. However, the specific COA page I could access was for Peppermint Oil (SKU 7495), not NOW Iron 18 mg, and I did not find an independently verifiable COA or certification page for this exact product.

NOW Canada product page says: “NOW uses Ferrochel® Iron Bisglycinate, which has clinically demonstrated superior absorption and is well tolerated because it is gentle and non-constipating.” The same page also says NOW is “audited and certified by Intertek” on its Seals & Certifications page, but I did not find an independently verifiable product-specific certification or COA for this exact product.
