Himalayan Goji
Also known as: Lycium barbarum, Goji berry, Goji, Wolfberry
Overview
Lycium barbarum, commonly known as the Goji berry, is a fruit native to Asia and has been used in traditional Chinese medicine for centuries. It is recognized for its high antioxidant content, including carotenoids like zeaxanthin, as well as various vitamins and minerals. Goji berries are available in several forms, including dried fruit, juice, and supplements. They are often consumed to support cardiovascular health, vision, and immune system function. Research on Goji berries is moderately mature, with a growing body of evidence from systematic reviews and meta-analyses suggesting potential health benefits. However, the quality of evidence varies, and further research is needed to fully understand the extent and mechanisms of these benefits. Sourcing from reputable suppliers is important to avoid contamination.
Benefits
Goji berries have shown potential benefits in several areas. A meta-analysis suggests that goji berry supplementation may reduce cardiometabolic risk factors, indicating a positive impact on cardiovascular health. Some evidence also supports benefits for vision health, particularly in age-related macular degeneration, although more research is necessary to confirm these findings. Animal studies have indicated potential prebiotic effects and improvements in colitis symptoms, suggesting benefits for gastrointestinal health. Additionally, animal studies suggest hepatoprotective effects. Older adults may experience improved quality of life and vision health with regular consumption. While effect sizes are generally moderate, consistent use over weeks to months may be required to observe noticeable benefits.
How it works
Goji berries are believed to exert their effects through multiple mechanisms. Their high antioxidant content helps combat oxidative stress, potentially reducing inflammation and protecting cells from damage. The berries may also modulate gut microbiota, promoting a healthy balance of bacteria in the digestive system. Furthermore, they may interact with cardiovascular, gastrointestinal, and visual systems, influencing various physiological processes. At the molecular level, Goji berries likely target antioxidant pathways and may influence inflammatory mediators. While data on human bioavailability is limited, animal studies suggest that key compounds are absorbed into the body, contributing to their overall effects.
Side effects
Goji berries are generally considered safe for consumption, but potential side effects and interactions should be considered. Common side effects are not well-documented, but some individuals may experience gastrointestinal upset. Uncommon side effects could include allergic reactions or interactions with certain medications. Drug interactions are a concern, particularly with blood thinners and diabetes medications, as Goji berries may enhance their effects. Due to a lack of safety data, Goji berries are contraindicated during pregnancy and breastfeeding. Individuals with diabetes or those taking anticoagulants should exercise caution and monitor their health closely. It is important to consult with a healthcare professional before incorporating Goji berries into your diet, especially if you have underlying health conditions or are taking medications.
Dosage
There is no well-established minimum effective dose for Goji berries. Optimal dosage ranges vary, often based on traditional consumption patterns. As a general guideline, consuming Goji berries in amounts similar to typical dietary intake is advisable. There is no established maximum safe dose, so caution is recommended beyond typical dietary amounts. Goji berries can be consumed as juice, dried fruit, or supplements. Bioavailability may vary depending on the form and preparation method. There are no established required cofactors for Goji berry consumption. It is important to start with smaller amounts and monitor for any adverse effects.
