Organic Maqui Berry Powder

Q: Is maqui berry powder as effective as extract?

Extracts standardized for anthocyanin content provide more consistent and potent effects than raw powder, ensuring a more reliable dosage of active compounds.

Q: How soon can I expect results?

Some benefits, like anti-inflammatory effects, may appear within weeks, while metabolic improvements may take months of consistent supplementation.

Q: Is it safe to take daily?

Yes, clinical studies show good safety profiles for daily use at studied doses, but it's always best to consult with a healthcare provider.

Q: Can it replace medication for diabetes or cholesterol?

No, maqui berry may complement but should not replace prescribed treatments for diabetes or high cholesterol. Consult your doctor for medical advice.

Q: Does it help with weight loss?

There is no direct evidence to support weight loss effects from maqui berry supplementation. It is primarily used for its antioxidant and anti-inflammatory benefits.

Also known as: Aristotelia chilensis, Maqui berry, Chilean wineberry

Overview

Maqui berry (Aristotelia chilensis) is a dark purple berry native to South America, particularly Chile and Argentina. It is available as a dietary supplement, typically in powder or extract form, derived from dried berries. Maqui berry is primarily used for its antioxidant and anti-inflammatory properties, with potential benefits for metabolic health, cardiovascular function, skin protection, and eye health. The berry is rich in anthocyanins, especially delphinidin and cyanidin derivatives, as well as other polyphenols, fatty acids, and phytosterols, which contribute to its strong antioxidant capacity. Research on maqui berry is growing, with preclinical and clinical trials, including randomized controlled trials (RCTs) and systematic reviews, indicating promising results. The available evidence is of moderate quality, with RCTs demonstrating bioavailability and biological activity of key anthocyanins. Maqui berry is considered a polyphenol-rich antioxidant supplement.

Benefits

Maqui berry offers several evidence-based benefits. Its extracts exhibit high total polyphenol content (up to ~57 mg GAE/g) and potent free radical scavenging activity (64-66% DPPH inhibition), demonstrating strong antioxidant potential. Clinical trials and meta-analyses suggest improvements in metabolic homeostasis, including reductions in blood glucose and LDL cholesterol. For instance, a 3-month RCT in prediabetic individuals showed a 5% reduction in blood sugar and a 12.5% reduction in LDL cholesterol with 180 mg/day of maqui extract. Studies in smokers have also indicated decreased lung inflammation markers with maqui supplementation. Additionally, small clinical trials have shown increased tear production (~50%) in dry eye patients after 30-60 mg/day of maqui extract for 30 days. In vitro studies suggest potential skin protection by suppressing UV-induced damage in human skin fibroblasts. Prediabetic and metabolically compromised individuals may benefit most from blood sugar and lipid improvements, while smokers may experience anti-inflammatory benefits.

How it works

Maqui berry's benefits are primarily attributed to its high anthocyanin content, which acts as an antioxidant by scavenging reactive oxygen species. It modulates inflammatory pathways and improves glucose metabolism, potentially through enhanced insulin sensitivity or carbohydrate metabolism. The berry interacts with various body systems, including the vascular endothelium (reducing inflammation), pancreatic and hepatic metabolism (regulating glucose), the ocular surface (increasing tear production), and skin cells (providing UV protection). Key bioactive molecules include anthocyanins like delphinidin-3-O-glucoside and cyanidin-3-O-sambubioside, along with their metabolites such as protocatechuic acid and gallic acid. Human pharmacokinetic studies confirm rapid absorption of these anthocyanins, with peak plasma levels observed within 1-2 hours post-ingestion, supporting systemic biological activity.

Side effects

Maqui berry is generally regarded as safe, with no serious adverse events reported in clinical trials. Common side effects (>5%) have not been consistently reported. Uncommon side effects (1-5%) lack significant data. Rare side effects (<1%) are not documented in available clinical studies. However, caution is advised when using maqui berry with anticoagulants or antidiabetic drugs due to potential additive effects. There are no established contraindications, but caution is recommended during pregnancy and lactation due to limited data. Special population considerations include limited data in children and pregnant women. Overall, maqui berry appears to have a favorable safety profile, but further research is needed to fully assess potential risks in specific populations and with concurrent medications.

Dosage

Clinical studies suggest that benefits can be observed starting at 30-60 mg/day of concentrated extract for eye health and 180 mg/day for metabolic effects. Optimal dosage ranges from 180 mg to 2 g/day of standardized extract (e.g., Delphinol®), depending on the indication. Higher doses (up to 2 g twice daily) have been used in inflammation studies. The maximum safe dose is not clearly established, but doses up to 4 g/day have been used in studies without adverse effects. Maqui berry is absorbed rapidly, and studies suggest taking it with water under fasting conditions to maximize bioavailability. Standardized extracts with ≥35% total anthocyanins and ≥25% delphinidins are preferred for consistent effects. Powder form is less standardized but still beneficial. Bioavailability is enhanced by a fasting state, and anthocyanins are metabolized quickly, suggesting that multiple daily doses may help sustain plasma levels.
