Maqui Superberry
Also known as: Maqui berry, Maqui superberry, Aristotelia chilensis
Overview
Maqui berry, scientifically known as *Aristotelia chilensis*, is a dark purple berry indigenous to the temperate rainforests of Chile and Argentina. It is highly valued for its exceptional concentration of anthocyanins, particularly delphinidins, which are potent antioxidant compounds. Marketed as a 'superberry,' maqui is primarily used as a dietary supplement to support cardiovascular health, mitigate metabolic syndrome risk factors, and provide broad antioxidant benefits. A key distinguishing feature of maqui is the high bioavailability of its delphinidin monomers, which are more readily absorbed by the body compared to the polymerized anthocyanins found in many other berries. While direct, large-scale randomized controlled trials (RCTs) specifically on maqui are still emerging, its benefits are supported by broader research on anthocyanin-rich berries. It is available in various forms, including fresh berries, powders, and standardized extracts, with extracts often preferred for their concentrated delphinidin content.
Benefits
Maqui berry offers several evidence-based benefits, primarily stemming from its rich anthocyanin content. Its most significant effects include improvements in metabolic syndrome (MetS) risk factors, such as favorable changes in HDL cholesterol, blood pressure, and insulin sensitivity. These benefits are supported by meta-analyses of anthocyanin-rich berries, which show statistically significant improvements in these markers. Maqui also demonstrably improves antioxidant biomarkers and reduces oxidative stress, particularly in adults with cardiometabolic risks. While specific effect sizes for maqui alone are not always isolated in current literature, the overall evidence for berry intake points to these positive outcomes. Furthermore, there is a strong link between anthocyanin intake from berries, including maqui, and potential cardiovascular risk reduction. These benefits are typically observed over several weeks to months of consistent supplementation, with studies often showing results within 4 to 12 weeks. Adults with features of metabolic syndrome or obesity appear to benefit most from maqui supplementation.
How it works
Maqui berry exerts its beneficial effects primarily through its high concentration of anthocyanins, especially delphinidins. These compounds function as powerful antioxidants, effectively scavenging free radicals and thereby reducing oxidative stress throughout the body. Beyond their direct antioxidant action, anthocyanins also modulate inflammatory pathways, helping to mitigate chronic inflammation. They contribute to improved endothelial function, which is crucial for healthy blood vessel dilation and overall cardiovascular health. A unique aspect of maqui is the high bioavailability of its delphinidin monomers; unlike the polymerized anthocyanins found in many other berries, these monomers are more readily absorbed in the gut. Once absorbed, these metabolites circulate in the bloodstream, exerting systemic antioxidant and anti-inflammatory effects that contribute to the observed health benefits.
Side effects
Maqui berry supplementation is generally considered safe, with clinical trials reporting no serious adverse events. Any side effects are rare and typically mild, primarily limited to occasional gastrointestinal discomfort in some individuals. There are no significant drug interactions or contraindications that have been definitively documented in the scientific literature. However, as with many supplements, there is insufficient data regarding the safety of maqui berry for special populations such as pregnant or lactating women, and children. Therefore, caution is advised for these groups, and consultation with a healthcare professional is recommended before initiating supplementation. Overall, maqui berry has a favorable safety profile when consumed within recommended dosages.
Dosage
The effective dosage of maqui berry varies depending on the form and standardization, but studies typically use maqui extract capsules standardized for delphinidins. Common dosages in research range from 100 mg to 300 mg of total anthocyanins daily. For instance, a dose of 250 mg/day of a maqui extract has shown metabolic benefits in clinical trials. While an optimal dosing regimen is not yet firmly established, it generally aligns with the amounts used in these successful randomized controlled trials. The timing of supplementation is flexible, and absorption may be enhanced when taken with meals. For maximum bioavailability and efficacy, purified extracts with a high content of monomeric delphinidins are preferred over less concentrated forms.
FAQs
Is maqui berry safe for daily use?
Yes, within the studied and recommended dosages, maqui berry is considered safe for daily use with minimal reported side effects.
How soon do benefits appear?
Improvements in antioxidant markers and metabolic parameters can typically be observed within a few weeks to months of consistent supplementation.
Is fresh maqui berry better than extract?
Extracts standardized for delphinidin monomers often offer better bioavailability and higher concentration of active compounds compared to fresh berries, due to the nature of anthocyanin polymerization in whole fruit.
Can it replace medication?
No, maqui berry should be considered a complementary supplement to support health, not a substitute for prescribed medications or medical treatments.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC9382680/ – This systematic review and meta-analysis of 54 randomized controlled trials found that berry intake, including maqui, significantly improves HDL cholesterol levels and reduces various metabolic syndrome risk factors. The study utilized robust meta-analytic methods, though it noted heterogeneity among studies and was not exclusively focused on maqui.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10295504/ – This high-quality systematic review, encompassing 54 RCTs, concluded that dietary berries significantly improve antioxidant biomarkers and reduce oxidative stress in adults with cardiometabolic risks. While it combined data from various berries, it strongly supports the antioxidant benefits attributed to maqui.
