MaquiBright (Aristotelia chilensis extract)

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 against oxidative stress in ocular tissues.

Origin & History

MaquiBright is a branded, standardized extract from the berries of Aristotelia chilensis (maqui), an evergreen shrub native to Chile and Argentina. The berries are typically wild-harvested or ethically sourced from optimal growing regions in Chile, and extracted using water or ethanol methods to preserve bioactive compounds. The extract is standardized to contain ≥25% delphinidins and ≥35% total anthocyanins.

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.

Health Benefits

• May provide dry eye relief (limited clinical evidence mentioned but no study details provided)
• Exhibits potent antioxidant activity 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 through phytosterols like β-sitosterol (preclinical evidence only)
• Potential blood sugar support through antidiabetic compounds (preclinical contexts only)

How It Works

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 reaches 283-284 mg Trolox equivalents per liter in standardized extracts.

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 properties rather than controlled human trials.

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 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.

Safety & 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.
