Goji Berry Extract Pdr

Also known as: Lycium barbarum, Goji Berry, Wolfberry

Overview

Goji berries, derived from the *Lycium barbarum* plant, are a fruit traditionally used in Asian medicine and now widely consumed as a dietary supplement. They are known for their rich antioxidant content, vitamins, and minerals. Goji berries are available in various forms, including dried berries, juice, and polysaccharide extracts. They are often used to enhance general well-being, improve vision, and support immune function. Research suggests potential benefits for metabolic health, including improving lipid profiles and glucose metabolism. The active components, particularly polysaccharides, are believed to contribute to these effects. While generally considered safe, potential interactions with certain medications should be considered. The level of research maturity is moderate, with a growing body of evidence supporting its health effects, though the quality of studies varies.

Benefits

Goji berries may improve lipid profiles by increasing HDL cholesterol levels and support glucose metabolism. A systematic review and meta-analysis showed favorable effects on HDL cholesterol levels in adults. They also enhance general well-being, including energy levels, sleep quality, and mental focus, as demonstrated in a randomized, double-blind, placebo-controlled trial. There is evidence suggesting benefits for immune function, with increases in lymphocytes and IgG levels, particularly in older adults. The clinical significance of these effects is moderate, with some studies showing statistically significant improvements in metabolic and psychological parameters. Benefits can be observed within a few weeks of supplementation, depending on the specific health outcome being measured.

How it works

Goji berries influence lipid and glucose metabolism through their antioxidant and polysaccharide components. These components may interact with immune pathways by enhancing lymphocyte counts and cytokine production. They interact with the cardiovascular system by improving lipid profiles and potentially with the immune system by enhancing immune cell function. While specific molecular targets are not well-defined, the mechanism likely involves antioxidant pathways and immune cell receptors. The bioavailability of goji berry extracts varies depending on the form of administration, such as juice versus dried products, affecting the extent of these interactions.

Side effects

Goji berries are generally considered safe when consumed in typical dietary amounts. Common side effects are not well-documented, but gastrointestinal upset is possible. Uncommon side effects include allergic reactions in some individuals. Data on rare side effects is limited. Potential drug interactions exist with anticoagulants and diabetes medications due to their effects on glucose and lipid metabolism. Goji berries are contraindicated during pregnancy and breastfeeding due to limited safety data. Caution is advised in individuals with diabetes or those taking anticoagulant medications. It is important to monitor for any adverse reactions and consult with a healthcare provider if any concerns arise.

Dosage

The minimum effective dose of goji berries is not well-established, but typical dosages range from 120 mL of juice to 150-300 mg of polysaccharide extracts per day. Optimal dosage ranges vary from study to study, but generally fall within the range of 120 mL to 90 g per day. The maximum safe dose is not clearly defined, but high doses are generally avoided due to potential interactions. There are no specific timing recommendations, but consistent daily intake is typical. Juice, dried products, and polysaccharide extracts are common forms. Bioavailability may vary based on the form of administration. No specific cofactors are required.

FAQs

How should I incorporate goji berries into my diet?

Goji berries can be consumed as part of a balanced diet or as a supplement. They are generally safe but should be used cautiously in certain health conditions. Consistent daily intake is recommended for best results.

Are there any safety concerns I should be aware of?

While generally safe, potential interactions with medications, especially anticoagulants and diabetes medications, should be considered. Consult with a healthcare provider if you have any underlying health conditions.

What kind of results can I expect from taking goji berries?

Improvements in energy, sleep, and metabolic health may be observed with regular consumption. However, goji berries are not a cure-all and should be used as part of a comprehensive health strategy.

Is there an optimal time of day to take goji berry supplements?

There is no specific timing recommendation, but consistent daily intake is typical. Choose a time that is convenient for you to ensure regular consumption.

Can goji berries cure diseases?

Goji berries are not a cure-all and should be used as part of a comprehensive health strategy. They may offer benefits for metabolic health, energy, and sleep, but are not a substitute for medical treatment.
