While these findings are promising, it’s important to note that more research is needed to fully understand the extent of goji berries’ impact on immune function. Many of the studies conducted thus far have been in vitro (in a test tube) or animal studies, and the results may not directly translate to humans. Additionally, factors such as individual health status, dosage, and duration of consumption can influence the potential immune-boosting effects of goji berries.
Inflammation and Chronic Disease: Goji Berries’ Potential Anti-Inflammatory Effects
Inflammation is a natural response of the body’s immune system to injury or infection. However, when inflammation becomes chronic, it can contribute to the development of various health problems, such as heart disease, diabetes, and certain cancers. This is where the potential anti-inflammatory properties of goji berries come into play.
Goji berries contain compounds called lyceum barbarum polysaccharides (LBPs), which have been studied for their potential anti-inflammatory effects. A 2019 review published in the journal Foods summarized the findings of multiple studies, suggesting that LBPs may help reduce inflammation by modulating the production of pro-inflammatory compounds in the body.
Furthermore, goji berries are a source of other anti-inflammatory compounds, such as zeaxanthin and betaine. Zeaxanthin is a carotenoid that has been shown to possess antioxidant and anti-inflammatory properties, while betaine is an amino acid derivative that may help reduce inflammation and protect against oxidative stress.
While the anti-inflammatory potential of goji berries is intriguing, it’s crucial to remember that most of the research in this area has been conducted in animal models or cell cultures. More human studies are needed to determine the effectiveness of goji berries in reducing inflammation and preventing chronic diseases in people.

The eyes are a complex and delicate organ, and maintaining their health is crucial for overall well-being. Goji berries have gained attention for their potential to support eye health, thanks to their unique blend of nutrients.
Goji berries are a rich source of zeaxanthin and lutein, two carotenoids that are particularly important for eye health. These compounds are concentrated in the macula, the central part of the retina responsible for sharp, detailed vision. Zeaxanthin and lutein act as natural sunscreens for the eyes, protecting them from harmful blue light and reducing the risk of age-related macular degeneration (AMD), a leading cause of vision loss in older adults.
A 2011 study published in the journal Optometry and Vision Science found that daily consumption of goji berry juice for 90 days led to an increase in the levels of zeaxanthin and lutein in the blood and macular pigment density in healthy adults. These findings suggest that goji berries may indeed support eye health by providing the building blocks necessary for optimal macular function.
However, it’s important to note that while the connection between goji berries and eye health is promising, more research is needed to fully understand the extent of their benefits. Factors such as individual differences in absorption and metabolism of zeaxanthin and lutein may influence the effectiveness of goji berries in supporting eye health.
Blood Sugar Management: Goji Berries’ Potential Role
Maintaining healthy blood sugar levels is crucial for overall well-being, particularly for individuals with diabetes or those at risk of developing the condition. Some research suggests that goji berries may have a potential role in supporting blood sugar management.
A 2015 study published in the journal Medicine found that consuming goji berry extract for three months led to significant improvements in blood sugar control and insulin sensitivity in individuals with type 2 diabetes. The researchers attributed these benefits to the presence of polysaccharides and other bioactive compounds in goji berries.
Another study published in the Journal of Functional Foods in 2018 investigated the effects of goji berries on blood sugar levels in healthy adults. The study found that consuming goji berries with a high-carbohydrate meal led to a significant reduction in postprandial (after-meal) blood sugar levels compared to a control group.
While these findings are encouraging, it’s essential to approach the potential blood sugar-regulating effects of goji berries with caution. More research, particularly long-term human studies, is needed to determine the optimal dosage and duration of goji berry consumption for blood sugar management. Additionally, individuals with diabetes should always consult with their healthcare provider before incorporating new foods or supplements into their diet, as goji berries may interact with certain medications or have unexpected effects on blood sugar levels.
