One camu-camu study

In one small crossover trial, selected adults with overweight and high triglycerides were assigned to two 12-week periods, separated by a 4-week washout. During the camu-camu period, participants took 1.5 g a day of whole camu-camu berry powder in capsules—the trial regimen, not a personal dose recommendation. The authors reported a change in MRI-measured liver fat, expressed as a relative change; MRI results were available for fewer participants than completed the trial, and 30 of 35 participants completed both periods. This does not show that ordinary powders or products have the same effect.

Trial method: 35 adults entered; two randomised orders each had a 12-week camu-camu capsule period and a 12-week placebo period with a 4-week washout between. 30 completed both periods. MRI hepatic-fat analysis had n=20 camu-camu-period and n=25 placebo-period observations, not 45 distinct people.
How the trial was organised. The two groups took the capsule preparations in opposite orders, with a four-week washout between 12-week periods. Of 35 people included, 30 completed both periods. MRI hepatic-fat analysis used 20 camu-camu-period and 25 placebo-period observations; these figures must not be added into a participant count. Source: the primary study. This describes the trial method, not an effect or dose recommendation for retail products.

Primary study: PMC11384942.

In plain language, this trial measured liver fat in a selected group of adults; it did not test general wellbeing or compare retail products. One small study cannot establish a general health benefit, and its capsule preparation does not show that ordinary powders or other products have the same effect.
