Allophycocyanin is a phycobiliprotein pigment found in cyanobacteria and certain algae. It is not traditionally used in herbal or folk medicine, but its use as an antioxidant is supported by a growing body of scientific research. Allophycocyanin and related phycobiliproteins (such as phycocyanin) have been shown in laboratory studies to possess strong antioxidant properties. These proteins can scavenge free radicals and inhibit oxidative stress in vitro, and there is evidence that they can protect cells from oxidative damage induced by free radicals. For example, studies published in peer-reviewed journals have demonstrated that allophycocyanin can reduce levels of reactive oxygen species (ROS), enhance antioxidant enzyme activities (like superoxide dismutase and catalase), and decrease lipid peroxidation in cell and animal models.

However, while these effects are promising, most of the evidence is preclinical, meaning it comes from test tube or animal studies rather than human clinical trials. There are currently few, if any, robust clinical studies directly evaluating allophycocyanin supplementation in humans for the purpose of combating free radical damage or related diseases. Therefore, while the scientific rationale for its use exists and experimental data are supportive, clinical validation is limited. As such, allophycocyanin’s use for free radical damage is best described as “scientific” with moderate evidence (rating: 3/5).
