Organic Goji Extract

Also known as: Lycium barbarum, Goji berry, Wolfberry

Overview

Goji berries, scientifically known as *Lycium barbarum*, are fruits native to Asia, celebrated for their high antioxidant content. They are commonly available as dried fruits or in extract form, and are incorporated into dietary supplements. Goji berries are rich in carotenoids, particularly zeaxanthin, which contributes significantly to their antioxidant properties. Primary uses include supporting ocular and cardiovascular health, providing antioxidant effects, and modulating immune function. Research on goji berries is ongoing, with studies exploring various health benefits. While some studies show promising results, more rigorous, large-scale trials are needed to draw definitive conclusions about their efficacy. Goji berry extracts are believed to combat oxidative stress and support overall well-being.

Benefits

Goji berry extracts are primarily recognized for their antioxidant effects, supported by studies showing increases in antioxidant markers like superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). The zeaxanthin content in Goji berries may also contribute to ocular health by reducing oxidative stress in the eyes. Secondary benefits include potential immune modulation and cardiovascular support, although these require further research. Middle-aged and older adults may particularly benefit from the reduced oxidative stress associated with Goji berry consumption. Studies have observed moderate increases in antioxidant markers, but the clinical significance can vary. Benefits may be observed within weeks to months of consistent consumption.

How it works

Goji berries exert their effects primarily through antioxidant pathways, largely due to carotenoids like zeaxanthin. These compounds scavenge free radicals, particularly hydroxyl radicals, thereby reducing oxidative stress. Goji berries interact with the body's immune system, supporting its function and potentially protecting against oxidative stress-related diseases. The bioavailability of active compounds in Goji berries can vary, and further research is needed to fully understand their absorption rates. By neutralizing free radicals, Goji berries help maintain cellular health and overall well-being.

Side effects

Goji berries are generally considered safe when consumed in typical dietary amounts. Common side effects are not well-documented in peer-reviewed literature, but uncommon side effects may include potential allergic reactions or gastrointestinal upset in sensitive individuals. Rare side effects are not well-documented. Goji berries may interact with blood thinners or diabetes medications due to their antioxidant effects, potentially altering the efficacy or safety of these drugs. They are contraindicated during pregnancy and breastfeeding due to a lack of comprehensive safety data. Caution is advised for individuals with allergies or those taking medications that may interact with antioxidants.

Dosage

The minimum effective dose of Goji berry extract is not well-established, but typical doses range from 15 g of dried berries to 60 mL of Goji berry extract per day. Optimal dosage ranges vary by study, and more research is needed to determine precise recommendations. The maximum safe dose is also not established, so caution is advised when exceeding typical dietary amounts. Consistent daily consumption may be beneficial. Dried berries and extracts are common forms. Bioavailability may vary based on the preparation method and individual factors. No specific cofactors are required for Goji berry consumption.

FAQs

Is Goji berry extract safe to consume?

Goji berry extract is generally safe, but it may interact with certain medications like blood thinners. Consult a healthcare provider if you have concerns.

When is the best time to take Goji berry extract?

Consistent daily intake is recommended for optimal benefits. You can take it at any time of day, but consider taking it with food to improve absorption.

How long does it take to see results from Goji berry extract?

Potential antioxidant benefits may be observed within weeks to months of consistent use. Individual results can vary based on dosage and overall health.

Are the health benefits of Goji berry extract overhyped?

While Goji berry extract offers potential health benefits, it's important to have realistic expectations. More research is needed to fully understand its effects.

Research Sources

https://www.explorationpub.com/Journals/eff/Article/101070 – The study by Amagase et al. was a randomized, double-blind, placebo-controlled trial involving 50 healthy adults aged 55–72 over 30 days. The key findings showed significant increases in antioxidant markers like SOD and GSH-Px, suggesting potential antioxidant benefits from Goji berry consumption. However, the study was limited by its short duration and a limited understanding of bioavailability, resulting in a moderate quality assessment.
https://pmc.ncbi.nlm.nih.gov/articles/PMC8868247/ – The study by Toh et al. was a randomized controlled trial with 40 participants aged 50–64 over 16 weeks. The study found increased plasma zeaxanthin levels and reduced oxidative stress, indicating potential benefits for ocular health. The study's limitations include a small sample size and a specific population, leading to a moderate quality assessment.
https://journals.lww.com/md-journal/fulltext/2021/12100/efficacy_of_lycium_barbarum_l__on_plasma_lipid.73.aspx – The systematic review and meta-analysis protocol aims to assess the effects of Lycium barbarum on plasma lipid concentrations. While the study is not yet completed, it has the potential for a comprehensive analysis if completed. The limitations include the potential for heterogeneity depending on the included studies.
