4 peer-reviewed studies
What the evidence says
Mostly mechanism / observational
Most Acerola studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from mixed-quality studies published 2011–2024.

A compositional review confirming acerola is among the richest natural sources of ascorbic acid (1500-4500 mg/100g) but framing benefits around its nutrient profile rather than clinical outcome trials.
Acerola contains an exceptionally high ascorbic acid content of roughly 1500-4500 mg/100g, ~50-100x that of orange or lemon
Also rich in carotenoids, phenolics, anthocyanins and flavonoids with high antioxidant capacity in assays
Described as an underutilized 'functional food'; review is compositional, not a clinical efficacy trial
A narrative review summarizing acerola's anti-inflammatory and antioxidant activity, largely from in-vitro and preclinical reports rather than human trials.
Reviews proposed anti-inflammatory and anticancer effects of acerola fruit and leaves
Mechanistic basis attributed to vitamin C and polyphenols / strong anti-free-radical effects
Evidence base is predominantly in-vitro and preclinical; not a human efficacy trial
In mouse blood cells, acerola extract showed no genotoxicity and protected DNA against oxidative damage, with unripe fruit (higher vitamin C) more protective.
Acerola extracts showed no genotoxic or cytotoxic potential in the Comet/MTT assays (mouse blood cells)
Unripe fruit, with higher measured vitamin C, gave greater DNA protection and DPPH radical inhibition than ripe fruit
Preclinical antioxidant/antigenotoxicity model — not a human clinical outcome

In vitamin-C-deficient hairless mice, acerola juice intake suppressed UVB-induced skin pigmentation, partly by downregulating a melanin-biosynthesis enzyme.
Acerola juice restored skin vitamin C and suppressed UVB-induced increases in skin pigmentation (L* value) in knockout mice
Associated with reduced expression of dopachrome tautomerase, a melanin-biosynthesis enzyme
Animal model in vitamin-C-deficient mice; results do not establish a skin benefit in humans
