Organic Lycium Berry Extract

Also known as: Lycium barbarum, Goji berry, Wolfberry

Overview

Lycium barbarum, commonly known as goji berries, are native to Asia and have been used in traditional medicine for centuries. These berries are rich in antioxidants, vitamins, and minerals, making them a popular dietary supplement and functional food. Goji berries are primarily used for their potential health benefits, including improving vision, supporting immune function, and enhancing overall well-being. The key characteristics of goji berries include their high antioxidant content, particularly polysaccharides and carotenoids. Research on goji berries is considered to be at a moderate level, with increasing interest in clinical trials. However, the quality of available evidence varies, with some high-quality studies alongside limitations in study design and sample sizes. They are available in various forms, including dried berries, juice, and extracts.

Benefits

Goji berries have been associated with several potential health benefits. Some studies suggest improvements in energy levels, sleep quality, mental focus, and gastrointestinal regularity. Research also indicates potential benefits in lipid and glucose metabolism. Enhanced immune function, as evidenced by increased lymphocytes and IL-2 levels, has also been reported, particularly in older adults. While the effect sizes are generally small to moderate, benefits are typically observed within a few weeks of supplementation. However, more research is needed to precisely quantify these effects and confirm the clinical significance of these findings.

How it works

The mechanism of action of Lycium barbarum is primarily attributed to its antioxidant activity, which helps neutralize free radicals and reduce oxidative stress. It also modulates the immune response, potentially enhancing immune function. Additionally, goji berries may influence metabolic pathways, contributing to improvements in lipid and glucose metabolism. While the exact molecular targets are not well-defined, it is believed that antioxidant and anti-inflammatory pathways are involved. Polysaccharides present in goji berries are thought to be absorbed in the gut, contributing to their overall bioavailability.

Side effects

Goji berries are generally considered safe for most people, but some side effects and precautions should be considered. Common side effects are rarely reported but may include mild gastrointestinal upset. Uncommon and rare side effects are not well-documented, although potential allergic reactions are possible. Due to limited data, caution is advised when using goji berries with anticoagulants and diabetes medications, as they may interact. Goji berries are contraindicated during pregnancy and breastfeeding due to a lack of safety data. Individuals with diabetes or those taking anticoagulants should exercise caution. More data are needed on the long-term use of goji berries to fully assess their safety profile.

Dosage

The minimum effective dose of Lycium barbarum is not well-established, but typical dosages range from 120 mg to several grams per day. Optimal dosage ranges are variable and often based on traditional use rather than clinical evidence. The maximum safe dose is not defined, but high doses may be associated with gastrointestinal side effects. There are no specific timing recommendations for consumption. Goji berries are often consumed as dried berries, juice, or extracts. Bioavailability may be influenced by gut health. No specific cofactors are required for their activity. It is important to note that these recommendations are general guidelines, and individual needs may vary.

FAQs

How can I ensure the quality of goji berry products?

To minimize contamination risks, ensure that goji berry products are sourced from reputable suppliers who adhere to quality control standards.

Are there any potential interactions with medications?

While generally safe, monitor for potential interactions with medications, especially anticoagulants and diabetes medications. Consult with a healthcare provider if you have concerns.

When is the best time to take goji berry supplements?

There are no specific timing recommendations for taking goji berry supplements. They can be consumed at any time of day, depending on personal preference.

How long does it take to see results from taking goji berries?

Improvements in energy and well-being may be noticeable within a few weeks of regular consumption. However, individual results may vary.

Are the health benefits of goji berries overhyped?

While goji berries offer potential health benefits, it's important to avoid overestimating their effects without robust clinical evidence. More research is needed to confirm many of the claimed benefits.
