Goji Fruit Juice Powder

Also known as: Goji berry, Wolfberry, *Lycium barbarum*

Overview

Goji berries, derived from the plant *Lycium barbarum*, are native to East Asia, particularly thriving in regions of China such as Ningxia and Xinjiang. Historically utilized in traditional Chinese medicine, these berries have gained popularity for their potential health benefits. Goji berries are rich in a variety of bioactive compounds including polysaccharides, carotenoids, and flavonoids, contributing to their antioxidant and immune-modulating properties. Generally consumed in forms such as juice, tea, or dried fruits, they serve as a dietary supplement and functional food. Currently, research support for their benefits is moderate; however, many studies highlight their promising roles in enhancing immune response and antioxidant levels, underlining their status as a health-promoting food with ongoing investigations into their therapeutic potential.

Benefits

Goji berries exhibit several evidence-based benefits: 1) **Immune Modulation** - Studies indicate they can enhance immune function by increasing lymphocyte counts and interleukin levels, particularly in elderly populations. 2) **Antioxidant Effects** - Consuming goji berries has been associated with significant increases in antioxidant markers, including superoxide dismutase and glutathione peroxidase. 3) **Mental Health Support** - Some evidence suggests potential benefits for individuals experiencing subthreshold depression. 4) **Ocular Health** - Research indicates they may aid in preserving macular integrity and lowering the risk of age-related macular degeneration. Strength of evidence varies, highlighting the necessity for additional research to substantiate effect sizes and clinical significance.

How it works

Goji berries exert their effects primarily through antioxidant, anti-inflammatory, and neuroprotective pathways. The bioactive compounds within the berries interact with the immune, nervous, and cardiovascular systems to modulate oxidative stress and enhance immune response. Specifically, compounds such as zeaxanthin are linked to improved bioavailability, particularly when formulated appropriately. Collectively, these interactions support overall health, particularly in individuals who are prone to oxidative stress.

Side effects

Goji berries are generally recognized as safe for most individuals. Common side effects are rare, but some users may experience gastrointestinal discomfort. Uncommon side effects have not been extensively documented. Rarely, allergic reactions may occur, and caution is advised for those on blood thinners or diabetes medications due to potential interactions. Furthermore, pregnant or breastfeeding women are advised to avoid goji due to a lack of sufficient safety data. Elderly individuals should use caution as well, monitoring for possible interactions with concurrent medications.

Dosage

The minimum effective dose of goji juice is recommended to be around 120 mL per day, whereas the optimal dosage for dried berries is typically between 15 g and 28 g. While a maximum safe dose has not been clearly defined, it is prudent to exercise caution above recommended levels. Consistent daily intake is important to realize benefits, and both juice and dried forms are popular methods of consumption. Additionally, absorption may vary depending on formulations used, which implies that some products could enhance bioavailability of key nutrients.
