What are SOD and SOD-Like? Antioxidant Testing FAQ

What is SOD? Is SOD-Like the same as SOD?

SOD stands for superoxide dismutase, a family of antioxidant enzymes found in humans, other animals, plants and microorganisms. SOD catalyzes the conversion of superoxide radicals (O₂•⁻) into hydrogen peroxide and oxygen, making it an important part of biological antioxidant defenses.

SOD is an enzyme with a defined identity, structure and catalytic reaction.

How do SOD and ORAC differ?

SOD is an antioxidant enzyme that acts on superoxide radicals. ORAC stands for oxygen radical absorbance capacity and is an in vitro antioxidant-capacity assay. The common fluorescence-based method measures how well a sample inhibits oxidation caused by peroxyl radicals, usually expressed in Trolox equivalents.

SOD identifies an enzyme. ORAC describes how a sample performs in a particular antioxidant assay.

The ORAC value is not the SOD enzyme content, nor can it be directly converted to SOD or SOD-Like activity units.

So what is SOD-Like?

SOD-Like means superoxide dismutase-like activity. The key word is "like."

The term usually describes a plant extract, fermented material or blend that inhibits or scavenges superoxide-related reactions in a specific assay.

Various active compounds in fermented botanicals can show radical-inhibiting activity similar to SOD in vitro, hence the term SOD-Like. This describes the tested sample's activity, not identification of the SOD enzyme itself.

What do SOD-Like values tell us?

A result describes a specific sample's response under specific test conditions. Check its name, preparation, method, concentration, calculation and unit rather than judging the number alone. Results from different laboratories or methods cannot necessarily be ranked or converted directly.

What is the difference between SOD-Like, ORAC and DPPH?

The three assays examine different reaction systems. SOD-Like focuses on superoxide-related in vitro activity; ORAC commonly expresses peroxyl radical responses in Trolox equivalents; DPPH uses a stable radical as a chemical test reagent. Results are not interchangeable and do not directly represent the body's antioxidant capacity or a recommended daily intake.

Can in vitro antioxidant data establish anti-inflammatory or other effects in humans?

In vitro antioxidant data alone cannot establish those effects. Antioxidant assays and human inflammatory markers represent different levels of evidence. Claims for a specific product require human studies matching its formulation, dosage, population and outcomes. Research into botanical mechanisms cannot be treated as clinical evidence for this product.

Why supplement with SOD-Like?

Breathing, energy production, exercise, work and normal metabolism generate reactive oxygen species and free radicals every day. Environmental exposure, diet and daily routines can also influence oxidative stress.

The body has antioxidant enzymes such as SOD, alongside other defense and repair mechanisms. Oxidative stress can arise when reactive oxygen species production exceeds the body's capacity to regulate it. A balanced routine and plant-based nutrition are both worth attention.

Polyphenols, flavonoids and other phytochemicals from a varied plant-based diet contribute to everyday nutritional support.

SOD-Like in vitro test data can help characterize a plant-derived food. Decisions about additional supplementation should be based on your diet and individual needs, alongside balanced eating, regular sleep and appropriate exercise.

Why choose Five Botanical Polyphenol Peptide Enzyme?

The body faces different kinds of oxidative stress, and plants contain different protective compounds.

Our approach brings together a broad spectrum of botanical polyphenol nutrients.

Inspired by the multi-target approach used in European dietary supplement design, our formula combines Amla, Jabuticaba, Noni, Turmeric and Cinnamon. These undergo 1000 days of fermentation without added sugar, with a diverse blend of polyphenols, phytochemicals, peptides and other constituents at the heart of the design.

We measure activity directly as well as identifying compounds, using laboratory data to characterize the submitted samples.

Our antioxidant testing considers SOD-Like activity and ORAC (oxygen radical absorbance capacity). They assess different in vitro reactions and offer complementary views of a sample. Each result should be read alongside its method, sample name and unit.

The published reports also cover polyphenols, the resveratrol glucoside piceid, curcumin, CoQ10, NADH, β-NMN and other compounds. They relate to different ingredients, powders or tablet samples and cannot be combined into a per-serving composition or human-effect claim for the finished Five Botanicals product.

We report what has been verified, with each composition or activity result traceable to its original report.
