Maqui
Also known as: Aristotelia chilensis, Maqui, Chilean Wineberry
Overview
Maqui (Aristotelia chilensis) is a fruit native to South America, particularly Chile, and has been traditionally used by the Mapuche people for its medicinal properties. It is a rich source of anthocyanins and other polyphenols, which are potent antioxidants. As a dietary supplement, Maqui is available in various forms, including extracts and powders, and is incorporated into food products. Research suggests that Maqui may offer several health benefits, including reducing oxidative stress, alleviating inflammation, and supporting metabolic health. While studies have shown promising results, more comprehensive systematic reviews and meta-analyses are needed to fully establish its efficacy and safety. The fruit's high antioxidant content makes it a popular choice for those seeking to improve their overall health and well-being.
Benefits
Maqui demonstrates potential in reducing oxidative stress and inflammation, primarily due to its high anthocyanin content. Studies have shown that Maqui extract can decrease H2O2 levels and normalize IL-6 concentrations in smokers, indicating a reduction in oxidative stress markers. It also exhibits antinociceptive effects, comparable to conventional analgesics. Furthermore, Maqui may support glucose metabolic control by reducing glycosylated hemoglobin levels and has anti-inflammatory effects beneficial for conditions like inflammatory bowel disease, as observed in animal models. These benefits make Maqui particularly promising for smokers and individuals with metabolic disorders. However, the effect sizes and clinical significance require further investigation through larger, well-controlled human trials.
How it works
Maqui's health benefits are primarily attributed to its high concentration of polyphenols, especially delphinidins, which act as potent antioxidants. These compounds interact with various biological pathways to exert their effects. Maqui modulates stress responses and influences metabolic homeostasis by targeting pathways involved in inflammation, such as COX2 and IL-6. It affects the cardiovascular system by reducing oxidative stress and potentially improving lipid profiles. The exact mechanisms of absorption and bioavailability of Maqui's active compounds are still under investigation, but its observed effects suggest effective absorption and interaction with key body systems.
Side effects
Maqui is generally considered safe when consumed in moderate amounts. However, high concentrations may exhibit toxicity to certain cell types. Common side effects are not well-documented, but gastrointestinal upset could occur, similar to other polyphenol-rich supplements. Potential allergic reactions or interactions with medications are uncommon but possible. Rare side effects are not documented. Maqui may interact with anticoagulants due to its antiplatelet effects, so caution is advised for individuals with bleeding disorders. Pregnant or breastfeeding women should consult healthcare providers before using Maqui. Overall, while Maqui is relatively safe, it's important to be aware of potential interactions and to avoid excessive doses.
Dosage
The minimum effective dose of Maqui is not well-established, but interventions often use doses around 2 g of extract per day. Typical dosage ranges are between 1-4 g of extract daily. The maximum safe dose is not defined, but high doses may be toxic to certain cells. There are no specific timing recommendations for Maqui consumption. Extracts are the most commonly used form. Bioavailability may be enhanced with food intake. No specific cofactors are required for Maqui's effectiveness. It is important to adhere to recommended dosages and consult with a healthcare provider to ensure safe usage.
FAQs
How should I take Maqui?
Maqui can be consumed as a supplement or incorporated into food products. It may interact with certain medications, so consult with a healthcare provider before use.
Is Maqui safe?
Maqui is generally safe, but high doses should be avoided. If you experience any adverse effects, discontinue use and consult with a healthcare provider.
When should I take Maqui?
There are no specific timing recommendations for Maqui. It can be taken at any time of day, preferably with food to enhance absorption.
What benefits can I expect from taking Maqui?
Benefits may include improved antioxidant status and metabolic health. However, Maqui is not a cure-all; its benefits are generally supportive rather than therapeutic.

- https://www.mdpi.com/2304-8158/13/6/838 – This study investigated the effects of Maqui extract on smokers, finding that 2 g twice daily for two weeks significantly decreased H2O2 levels and increased IL-6 concentrations, indicating normalization of oxidative stress markers. The study's limitations include a small sample size and short duration, resulting in a moderate quality assessment.
- https://pubmed.ncbi.nlm.nih.gov/32293681/ – This in vivo study on mice with induced inflammatory bowel disease showed that Maqui extract reduced COX2 and IL-6 expression and alleviated gut microbiota imbalance. While the study provides high-quality preclinical evidence, its findings may not be directly applicable to humans.
- https://pubs.rsc.org/en/content/articlelanding/2024/fo/d3fo02524a/unauth – A 3-month clinical trial involving 31 subjects treated with Maqui extract showed improvements in glucose metabolism and lipid profiles. The study's limitations include a small sample size and lack of a control group, resulting in a moderate quality assessment.
- https://www.mdpi.com/2072-6643/13/12/4273 – This study likely investigates further health benefits of Maqui berries, focusing on their antioxidant and anti-inflammatory properties. More detailed information would be needed to provide a comprehensive summary of the specific findings and methodologies used.
