Cantaloupe Fruit Powder (SOD B Extramel®)

Cucumis melo

5 Documented Benefits
3/5 Evidence Score

Cantaloupe fruit powder used in supplements is most often SOD B Extramel® or similar concentrates derived from a specific melon (Cucumis melo) cultivar selected for its naturally high superoxide dismutase (SOD) content. The fresh melon juice is concentrated and combined with a gliadin-based coating that protects the SOD enzyme from gastric breakdown, allowing it to act in the upper GI tract and trigger systemic antioxidant signaling. Human randomized controlled trials of Extramel at 10 mg/day (≈140 IU SOD) for 4–12 weeks have evaluated effects on perceived stress, fatigue, sleep quality, and physical performance, making cantaloupe-derived SOD one of the more substantiated 'food-source enzyme' antioxidant ingredients.

Studied Dose 10 mg/day SOD B Extramel® (≈140 IU SOD) once daily for 4–12 weeks; some studies have used up to 40 mg/day.
Active Compound Concentrated Cucumis melo juice rich in superoxide dismutase (SOD), catalase, and natural antioxidants; commercial forms standardized to ~140 IU SOD per 10 mg, typically coated with wheat gliadin.

Benefits

Helps support a balanced stress response

Daily intake has been shown in human trials to help reduce perceived stress and fatigue symptoms in adults dealing with everyday demands, supporting a calmer day-to-day experience.

Supported by Trial 1

Promotes energy and reduced fatigue

Helps reduce signs and symptoms of physical and mental fatigue, including weariness and difficulty concentrating, contributing to improved daily energy.

Supported by Trial 1

Supports endogenous antioxidant defense

Encourages upregulation of the body's own antioxidant enzymes—including superoxide dismutase, catalase, and glutathione peroxidase—helping the body manage oxidative stress more effectively.

Supported by Trial 2

Helps maintain quality of sleep

Trials have observed improvements in sleep-related fatigue measures, supporting more restorative rest in adults under stress.

Supported by Trial 1

Convenient low-dose antioxidant

Delivers a clinically studied antioxidant effect at just 10 mg/day, fitting easily into stress, energy, and longevity formulas alongside other actives.

Supported by Trial 2, Trial 1

Mechanism of action

1

Gastroprotected SOD delivery

The gliadin coating protects native melon SOD from gastric inactivation, allowing the enzyme to reach the upper gastrointestinal tract where it can interact with epithelial cells and trigger downstream signaling.

2

Endogenous antioxidant induction

Oral SOD B Extramel has been shown in preclinical and human studies to upregulate expression and activity of endogenous antioxidant enzymes such as SOD, catalase, and glutathione peroxidase.

3

HPA-axis and cortisol modulation

By reducing systemic oxidative stress, melon SOD concentrate may help blunt cortisol responses and support a more balanced HPA-axis tone during chronic stress.

4

Mitochondrial protection

Improved superoxide neutralization helps preserve mitochondrial membrane potential and ATP production, supporting cellular energy availability.

Clinical trials

1
Extramel® melon concentrate for stress and fatigue

Pilot double-blind, placebo-controlled trial, 10 mg Extramel (140 IU SOD) daily for 4 weeks

n=70 healthy adults aged 30–55 with daily stress and fatigue

Supplementation produced significant improvements over placebo in measures of perceived stress and fatigue, including performance, physical (pain, sleep troubles), cognitive (concentration, weariness), and behavioural (attitude, irritability) dimensions, supporting a benefit for everyday stress and fatigue symptoms.

2
SOD-rich melon and oxidative stress

Background human and preclinical studies of melon-derived SOD on antioxidant enzyme activity

Healthy adults and animal models

Oral melon SOD concentrate has been associated with increased activity of endogenous antioxidant enzymes (SOD, catalase, glutathione peroxidase), supporting its mechanism as an inducer of the body's own antioxidant defenses rather than acting solely as a direct enzyme substitute.

Side effects and drug interactions

Common Potential side effects

Generally well tolerated at studied doses; mild GI upset is rare.
Contains wheat gliadin coating in some formulations—not suitable for celiac or wheat allergy.
Possible allergic reaction in individuals sensitive to melon or related cucurbits.
May cause mild flushing or warmth in sensitive individuals.
Headache occasionally reported during early supplementation.

Important Drug interactions

No clinically significant drug interactions have been documented at studied doses.
Sedative medications: theoretical additive effects on calming or fatigue-reducing endpoints.
Antioxidant chemotherapy: discuss high-dose antioxidants with oncology providers.
Antihypertensives: monitor blood pressure in individuals already on therapy.
