Zizyphus Sativa Seed Extract
Also known as: Ziziphus jujuba Seed Extract, Ziziphus spinosa Hu Seed Extract, Jujube seed extract, Zizyphus seed extract, Jujube seed capsule, Ziziphus jujuba Mill. Seed Extract
Overview
Ziziphus jujuba Mill. Seed Extract, commonly known as jujube seed extract, is derived from the seeds of the jujube fruit, primarily from *Ziziphus jujuba* or *Ziziphus spinosa* species. These trees are native to Asia and have a long history of use in traditional medicine. The extract is primarily recognized for its central nervous system (CNS) effects, including anxiolytic, sedative, and hypnotic properties, making it a popular choice for improving sleep quality. Beyond its CNS benefits, research also explores its antioxidant, metabolic (lipid and glycemic control), and potential anticancer effects. Its therapeutic properties are attributed to bioactive compounds such as saponins (jujubosides), flavonoids, and alkaloids, which modulate neurotransmitter systems and combat oxidative stress. While several clinical and animal studies exist, with some systematic reviews, more high-quality, large-scale human trials are needed to solidify its evidence base across all claimed benefits.
Benefits
Ziziphus jujuba Seed Extract offers several evidence-based benefits. A randomized controlled trial (RCT) demonstrated significant improvement in sleep quality scores in postmenopausal women, indicating its efficacy as a sleep aid. For antioxidant effects, a systematic review and meta-analysis of rodent studies showed that jujube fruit extracts significantly reduce oxidative stress markers with medium to large effect sizes, suggesting its potential to combat cellular damage. Clinical trials also indicate that jujube fruit consumption can improve serum lipid profiles and glycemic indices, partly by increasing adiponectin levels, which are crucial for regulating lipid metabolism and blood sugar. These metabolic benefits are particularly relevant for individuals with diabetes or lipid disorders. Additionally, animal studies suggest anxiolytic and sedative effects through GABAergic modulation, and preclinical research points to potential multi-target anticancer properties, though clinical evidence for the latter is currently lacking. Sleep benefits typically manifest after several weeks of consistent supplementation.
How it works
The primary mechanism of action for Ziziphus jujuba Seed Extract involves the modulation of neurotransmitter systems and antioxidant pathways. Its sedative and anxiolytic effects are largely attributed to the modulation of GABAergic and serotonergic neurotransmission, particularly by interacting with GABA-A receptors. This interaction helps to calm the central nervous system, promoting relaxation and sleep. The extract's antioxidant properties stem from its rich content of flavonoids and saponins, which act as free radical scavengers, reducing oxidative stress markers and protecting cells from damage. For its metabolic effects, the extract appears to influence lipid and glucose metabolism, partly by increasing adiponectin levels. While the exact pharmacokinetic details are limited, the bioactive compounds, such as jujubosides, are known to have moderate oral bioavailability, allowing them to exert their effects within the body.
Side effects
Ziziphus jujuba Seed Extract is generally considered safe when consumed within studied dosages, with no serious adverse events reported in clinical trials. The most commonly reported side effect, though infrequent, is mild gastrointestinal discomfort. There are no significant reports of uncommon or rare side effects in the available clinical data. However, caution is advised regarding potential drug interactions, particularly with other central nervous system (CNS) depressants, due to its inherent sedative properties. Combining it with sedatives or other CNS-active drugs could lead to additive effects. Contraindications are not well-defined, but due to a lack of sufficient data, it is recommended to exercise caution in pregnant and lactating women. While postmenopausal women have been a focus of some studies, more research is needed to fully understand its effects and safety profile across other specific populations.
Dosage
For improving sleep quality, clinical studies typically recommend a dosage range of 200-500 mg/day of Ziziphus jujuba Seed Extract. The exact milligram dose can vary depending on the specific product and standardization. Metabolic studies have utilized various forms, including syrups and powders, with doses adjusted accordingly. The maximum safe dose has not been clearly established, but no toxicity has been reported at the dosages studied. The extract is often administered daily, with some protocols suggesting multiple doses per day. It is available in various forms such as capsules, powders, and syrups, with seed extract specifically used for its CNS-related benefits. The absorption and bioavailability of its active compounds can be influenced by the extraction method, with hydroalcoholic extracts being commonly used. No specific cofactors are identified as necessary for its efficacy.
