Jujube extract is derived from the jujube fruit, which grows on the Ziziphus jujuba tree native to Asia. Also known as Chinese date, red date, or Korean date, jujube fruits have been used for over 4,000 years in traditional Chinese medicine and cuisine. Today, jujube extract is gaining popularity as a nutritional supplement due to its rich content of bioactive compounds and diverse health benefits. In this blog, we’ll explore the nutritional profile of jujube extract and review the scientific research on how it may support overall wellness.
Nutritional Profile and Bioactive Compounds in Jujube Extract
Jujube extract is nutritionally dense, containing a range of vitamins, minerals, amino acids, and other beneficial plant compounds. Some of the key nutrients found in jujube include (1,2):
- Vitamin C - An antioxidant that supports immune function and collagen synthesis. Jujube is very high in vitamin C.
- Vitamin A - Important for vision, immunity, and cell growth. Jujube contains high levels of provitamin A carotenoids.
- Iron - Critical for oxygen transport and energy metabolism. Jujube provides a good source of plant-based iron.
- Calcium - Needed for bone health, nerve transmission, and muscle function. Jujube supplies calcium and other minerals.
- Protein - Made up of essential amino acids necessary for tissue renewal and muscle growth.
Jujube extract also contains a variety of bioactive compounds such as triterpenic acids, flavonoids, polysaccharides, and cyclopropane fatty acids (3). These compounds exhibit antioxidant, anti-inflammatory, anti-anxiety, antidisease, and immunomodulating effects in research studies (4). The combination of nutrients and plant compounds gives jujube its therapeutic properties.
What Are the Benefits of Jujube Extract?
Health Benefits of Jujube Extract
Jujube’s antioxidant content helps counteract oxidative stress which contributes to chronic disease. Specific antioxidant compounds found in jujube include phenolic acids, flavonoids, polysaccharides, and triterpenoids (5). By neutralizing free radicals, these antioxidants can support overall health.
Some studies indicate jujube supports immune function. Jujube polysaccharides enhanced antibody production and natural killer (NK) cell activity in animal research (6). The antioxidants may also strengthen immunity by protecting white blood cells. These immune-boosting effects could help prevent illness.
Jujube Extract for Sleep and Stress Management
Traditional Chinese medicine has long used jujube to calm the mind, relieve anxiety, and promote restful sleep (7). Modern research has identified jujube’s calming mechanisms. It appears to increase serotonin and GABA, neurotransmitters involved in relaxation and sleep regulation (8).
Jujube extract has also been shown to reduce cortisol levels and anxiety in animal studies (9). The combination of jujube’s soothing effects may make it effective for insomnia and stress relief.
Digestive Health and Jujube Extract
Jujube fruit is considered a digestive aid in traditional practices. The fiber, nutrients, and phytochemicals in jujube support regularity and gastrointestinal function (10).
Studies also indicate jujube modulates the gut microbiota. It increased levels of beneficial bifidobacteria and lactobacilli in human trials (11). By optimizing the gut microbiome, jujube fruit extract may improve digestion and deliver prebiotic-like benefits.
Metabolic Health and Jujube Extract
Emerging evidence suggests jujube could offer benefits for metabolic health. Human studies report jujube decreases blood sugar levels in diabetic patients by improving insulin sensitivity and antioxidant status (12).
Jujube extract also reduced obesity-associated inflammation and liver fat accumulation in animal models of metabolic syndrome (13). More research is needed, but Jujube shows potential for supporting healthy blood sugar regulation.
Skin and Hair Benefits of Jujube Extract
With its antioxidant and anti-inflammatory properties, jujube may benefit skin health. Jujube extract exhibited anti-wrinkle effects when applied topically by protecting collagen and reducing inflammation in a rodent study (14).
Jujube’s immune-boosting ability could also help clear skin; one study found jujube polysaccharides reduced acne lesions (15). For hair, jujube fruit extract accelerated the anagen hair growth phase and increased the proliferation of dermal papilla cells in mice (16). This indicates it may combat hair loss and promote thicker, stronger hair.
Does Jujube Make You Sleep?
As mentioned earlier, jujube does appear to have mild sedative properties that can promote sleep. The flavonoids, saponins, and triterpenoids found in jujube act on GABA and serotonin receptors involved in sleep-wake cycles (8). Human and animal studies show jujube extract reduces sleep latency, increases non-REM and REM sleep, and improves overall sleep quality (17,18). The recommended dosage is 400-600 mg taken 30-60 minutes before bedtime.
Jujube Extract as a Nutritional Supplement
Jujube extract is available in capsule, liquid tincture, or powder forms. For general wellness, a dosage of 300-500 mg once or twice daily is common. For sleep support, 400-600 mg before bedtime is optimal. It’s best taken with food to increase absorption.
Jujube is generally well tolerated, but side effects can include drowsiness, diarrhea, nausea, and bloating when over-consumed. Jujube may interact with sedatives and blood sugar-lowering medications. As with any supplement, consult your doctor before use.
What Are the Side Effects of Jujube Extract?
Jujube extract powder is considered safe for most people when used appropriately (19). However, jujube may cause some mild side effects including:
- Drowsiness - Due to its calming effects, high doses can cause excessive sleepiness.
- Diarrhea - Jujube has laxative properties that could cause loose stools if over-consumed.
- Bloating and gas - The fiber in jujube can cause abdominal discomfort in sensitive people.
- Rash - Allergic reactions are uncommon but possible. Discontinue use if rash develops.
- Drug interactions - Jujube may increase sedation with anti-anxiety medications. It may also lower blood sugar and interact with diabetes medications.
To avoid side effects, stick to recommended dosages, start with small amounts and consult your doctor about potential medication interactions. Further studies are needed on the long-term safety of jujube supplements.
Conclusion
With its unique blend of antioxidants, minerals, and natural plant compounds, jujube fruit extract offers a wide array of potential benefits. Science indicates jujube can help strengthen immunity, calm the nervous system, support digestive health, and potentially regulate blood sugar levels. Topical jujube shows promise for improving skin and hair as well. Jujube’s calming properties also promote restful sleep. While more research is still needed, jujube extract is emerging as a versatile wellness supplement. As with any new supplement, speak to your healthcare provider to determine if jujube extract is right for you.
