Antioxidant Effects
To compare antioxidant and anti-inflammatory effects of camu camu vs vitamin C tablets
Study Type
Randomised, placebo-controlled
Purpose
To compare antioxidant and anti-inflammatory effects of camu camu vs vitamin C tablets
Dose
1638 mg/day camu camu powder (70 mg vitamin C)
Participants
20 male smokers
Duration
7 days
Results
Camu camu significantly reduced 8-OHdG and F2-isoprostanes vs placebo (p<0.05). Vitamin C tablets alone did not produce the same effect.
How They Measured It
ORAC, CRP, 8-OHdG, F2-isoprostanes
To evaluate camu camu supplementation on antioxidant status in obese adults
Study Type
Randomised, double-blind, placebo-controlled
Purpose
To evaluate camu camu supplementation on antioxidant status in obese adults
Dose
15 g/day camu camu pulp
Participants
30 obese adults
Duration
8 weeks
Results
Significant increase in plasma vitamin C (+64%), FRAP antioxidant capacity, and GSH. Lipid peroxidation reduced by 24%.
How They Measured It
Plasma vitamin C, FRAP, GSH, lipid peroxidation

Dose
10 g/day camu camu powder
Participants
27 adults with metabolic syndrome
Duration
8 weeks
Results
Significant improvements in waist circumference, plasma insulin, and CRP vs placebo. Gut microbiota diversity increased including Akkermansia and Lactobacillus.
How They Measured It
Glucose, insulin, lipids, CRP, gut microbiota
To evaluate camu camu extract on blood glucose and insulin
Study Type
Randomised, placebo-controlled
Purpose
To evaluate camu camu extract on blood glucose and insulin
Dose
100 mg camu camu extract with meal
Participants
20 healthy adults
Duration
Acute crossover
Results
Significant reduction in postprandial glucose AUC (p=0.02) and insulin response. Alpha-glucosidase inhibition as likely mechanism.
How They Measured It
Postprandial glucose, insulin, glucose AUC
To assess anti-inflammatory effects of camu camu in exercise-induced inflammation
Study Type
Randomised, placebo-controlled
Purpose
To assess anti-inflammatory effects of camu camu in exercise-induced inflammation
Dose
50 ml camu camu juice daily
Participants
22 trained athletes
Duration
4 weeks
Results
Significant attenuation of exercise-induced CRP rise (p=0.04) and IL-6. Cortisol response to exercise blunted. Recovery improved.
How They Measured It
CRP, IL-6, cortisol, muscle damage markers
Vitamin C Bioavailability
To compare vitamin C bioavailability from camu camu vs synthetic ascorbic acid
Study Type
Randomised, crossover pharmacokinetic study
Purpose
To compare vitamin C bioavailability from camu camu vs synthetic ascorbic acid
Dose
Equimolar vitamin C (70 mg) from camu camu vs ascorbic acid
Participants
12 healthy adults
Duration
Pharmacokinetic crossover
Results
Plasma vitamin C AUC comparable between sources. Urinary excretion lower with camu camu, suggesting better tissue retention.
How They Measured It
Plasma vitamin C AUC, urinary vitamin C excretion, Cmax
