## Overview

MaquiBerry extract (Aristotelia chilensis) is a standardized supplement containing ≥35% anthocyanins that supports tear production and eye moisture. The anthocyanins, particularly delphinidins and cyanidins, provide [antioxidant protection](/ingredients/condition/antioxidant) against oxidative stress in ocular tissues.

## Health Benefits

• May provide dry eye relief (limited clinical evidence mentioned but no study details provided)
• Exhibits potent [antioxidant activity](/ingredients/condition/antioxidant) through DPPH radical inhibition (283.63–284.60 mg Tx/L in extracts - in vitro evidence)
• Contains anthocyanins that may support eye health (standardized to ≥35% total anthocyanins - mechanism-based claim)
• May support [cardiovascular health](/ingredients/condition/heart-health) through phytosterols like β-sitosterol (preclinical evidence only)
• Potential blood sugar support through antidiabetic compounds (preclinical contexts only)

## Mechanism of Action

MaquiBerry's anthocyanins, primarily delphinidins and cyanidins, scavenge free radicals through DPPH inhibition and reduce oxidative stress in lacrimal glands. The compounds may stimulate aqueous tear production by protecting goblet cells and maintaining healthy tear film composition. [Antioxidant activity](/ingredients/condition/antioxidant) reaches 283-284 mg Trolox equivalents per liter in standardized extracts.

## Clinical Summary

Limited clinical evidence suggests MaquiBerry extract may provide dry eye relief, though specific study details including sample sizes and duration are not well-documented in available research. In vitro studies demonstrate potent [antioxidant activity](/ingredients/condition/antioxidant) with DPPH radical scavenging capacity of 283.63-284.60 mg Trolox equivalents per liter. Most commercial preparations are standardized to contain ≥35% anthocyanins by weight. Additional human trials are needed to establish optimal dosing protocols and confirm clinical efficacy for eye health applications.

## Dosage & Preparation

No clinically studied dosage ranges are available from human trials. Product examples include 983 mg dry berry extract per serving in liquid tinctures (1:3 dry plant-to-solvent ratio). MaquiBright is standardized to ≥25% delphinidins and ≥35% total anthocyanins, but specific therapeutic doses have not been established through clinical research. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

MaquiBerry extract appears generally well-tolerated with no serious adverse effects reported in available studies. No known drug interactions have been documented, though individuals taking blood-thinning medications should consult healthcare providers due to potential anthocyanin effects on platelet function. Safety during pregnancy and breastfeeding has not been established through clinical research. Individuals with berry allergies should exercise caution when using maqui berry-derived supplements.

## Scientific Research

The research dossier reveals a significant gap in human clinical trials for MaquiBright, with no PubMed PMIDs or detailed human studies provided. While one source mentions clinical proof for dry eye relief with MaquiBright, no study design, sample size, or specific outcomes are detailed. Current research focuses primarily on in vitro [antioxidant](/ingredients/condition/antioxidant) properties rather than controlled human trials.

## Historical & Cultural Context

Maqui (Aristotelia chilensis) berries have been used in traditional Chilean Mapuche medicine for centuries as food and for general well-being. The berries have served as both a nutritional source and traditional remedy, though specific medicinal indications and duration of use are not detailed in historical records.

## Synergistic Combinations

Lutein, Zeaxanthin, Bilberry extract, Astaxanthin, Omega-3 fatty acids

## Frequently Asked Questions

### What is the standardized anthocyanin content in MaquiBerry extract?

MaquiBerry extract supplements are typically standardized to contain ≥35% anthocyanins by weight. This standardization ensures consistent levels of the active compounds responsible for antioxidant and eye health benefits.

### How does MaquiBerry extract help with dry eyes?

MaquiBerry's anthocyanins may support tear production by protecting lacrimal glands from oxidative damage and maintaining healthy goblet cell function. The antioxidant compounds help preserve tear film quality and reduce eye dryness symptoms.

### What is the typical dosage of MaquiBerry extract for eye health?

Specific dosage recommendations for eye health applications are not well-established due to limited clinical research. Most supplement formulations contain 40-60mg of standardized extract, but optimal dosing requires further clinical validation.

### Can MaquiBerry extract be taken with other eye supplements?

MaquiBerry extract can generally be combined with other eye health supplements like lutein or zeaxanthin. However, consult a healthcare provider before combining supplements, especially if taking medications or having underlying health conditions.

### How long does it take to see benefits from MaquiBerry extract?

The timeline for experiencing eye health benefits from MaquiBerry extract is not well-documented in clinical literature. Individual responses may vary, and consistent daily use over several weeks may be necessary to observe potential improvements in dry eye symptoms.

### Is MaquiBright safe to use during pregnancy or while breastfeeding?

There is limited clinical safety data specifically for MaquiBright (Aristotelia chilensis extract) during pregnancy and lactation. Pregnant and breastfeeding women should consult with their healthcare provider before using this ingredient, as anthocyanin-rich extracts have not been extensively studied in these populations. Safety cannot be assumed based on traditional use alone.

### How does MaquiBright compare to other anthocyanin sources like bilberry or black currant for eye health?

MaquiBright is standardized to ≥35% total anthocyanins and demonstrates potent antioxidant activity (283.63–284.60 mg Tx/L) in vitro, making it comparable to other anthocyanin-rich botanicals. While bilberry and black currant also contain anthocyanins, MaquiBright's specific anthocyanin profile and extract standardization differ, though direct clinical comparison studies between these ingredients are limited. The choice between them may depend on individual tolerance, availability, and specific formulation benefits.

### What clinical evidence supports the antioxidant and eye health benefits of MaquiBright?

MaquiBright demonstrates potent antioxidant activity through DPPH radical inhibition in vitro studies, though this represents laboratory-based evidence rather than human clinical trials. Limited clinical evidence suggests potential benefits for dry eye relief, but specific study details and effect sizes have not been provided in available literature. More robust, peer-reviewed human studies are needed to establish the strength and magnitude of health benefits in actual users.
