Oxidation is a common challenge in the formulation and storage of dietary supplements—especially those containing oils, fatty acids (like omega-3s), or fat-soluble vitamins. When exposed to air, heat, or light, these sensitive ingredients undergo oxidative degradation, which can lead to:

Oxidation not only affects product quality but also consumer trust and brand reputation. That's why accurate, timely oxidation testing is essential.
At Alfa Chemistry, we provide industry-leading oxidation testing services tailored to the needs of dietary supplement manufacturers, marketers, and formulators. Backed by decades of expertise, we help you deliver products that remain fresh, stable, and safe—from production to the hands of consumers.
We measure peroxide compounds to assess primary oxidation in oils and fat-based ingredients. A high PV indicates initial spoilage and signals the need for immediate quality control. This test is crucial for fish oils, flaxseed oils, and other polyunsaturated fatty acid products.
As oxidation progresses, aldehydes form—leading to off-flavors and reduced product safety. Our p-Anisidine test accurately quantifies secondary oxidation products and provides insight into the long-term stability of your formulation.
By combining PV and AnV, the TOTOX value offers a complete picture of your product's oxidative status. This all-in-one metric is widely accepted by regulatory bodies and quality assurance programs around the world.
We also offer customized testing using advanced equipment to support deeper analysis or specialized needs:
