Jasmine Green Tea
Also known as: Jasmine green tea, Scented green tea, Jasmine tea, Camellia sinensis (Jasmine Green Tea)
Overview
Jasmine green tea is a flavored tea made by scenting green tea leaves with jasmine flowers. Originating primarily in China, it combines the health benefits of green tea (*Camellia sinensis*) with the aromatic properties of jasmine (*Jasminum* spp.). The key bioactive compounds include catechins (especially epigallocatechin gallate or EGCG), caffeine, L-theanine, and volatile aromatic compounds from jasmine such as benzyl acetate and linalool. It is consumed for its antioxidant effects, potential weight management benefits, cardiovascular health support, and relaxation properties. While green tea extract (GTE) is well-studied, research specific to jasmine green tea is less extensive, with most effects attributed to the green tea base. It is available as loose leaf tea, tea bags, and standardized extracts.
Benefits
Jasmine green tea, primarily through its green tea component, offers several evidence-based benefits. Meta-analyses show that green tea extract (GTE) supplementation can lead to modest reductions in body mass (BM), body fat percentage (BFP), and BMI (p < 0.05). GTE also increases total antioxidant capacity (TAC) and reduces malondialdehyde (MDA), a marker of oxidative stress. Furthermore, green tea supplementation has been shown to reduce triglycerides (TG) when the intervention lasts longer than 12 weeks. GTE can also increase adiponectin, a hormone associated with improved metabolic health. These effects are most consistent in adults with overweight/obesity or metabolic risk factors, typically observed after 8–12 weeks of consistent use.
How it works
The health benefits of jasmine green tea are largely attributed to the synergistic effects of its components. Catechins, particularly EGCG, act as potent antioxidants by scavenging free radicals and upregulating endogenous antioxidant enzymes. Metabolically, it increases energy expenditure and fat oxidation through catecholamine stimulation and inhibition of catechol-O-methyltransferase (COMT). The polyphenols present also modulate inflammatory pathways. These components primarily affect the metabolic, cardiovascular, and nervous systems. Key molecular targets include the Nrf2 pathway (antioxidant), beta-adrenergic receptors (metabolic), and adiponectin (metabolic). Catechin absorption is moderate and can be enhanced by consuming it on an empty stomach.
Side effects
Jasmine green tea is generally safe for most adults when consumed in typical dietary amounts. Common side effects, affecting more than 5% of users, include mild gastrointestinal upset and insomnia, primarily due to the caffeine content. Less common side effects (1-5%) may include headache, dizziness, and palpitations. Rare side effects (less than 1%) include reports of liver toxicity, mainly associated with high-dose extracts. It may interact with anticoagulants, stimulants, and certain antidepressants. Contraindications include pregnancy, severe liver disease, and caffeine sensitivity. Individuals with anxiety disorders, hypertension, or arrhythmias should exercise caution. Monitoring caffeine intake and starting with lower doses can help mitigate potential adverse effects.
Dosage
For metabolic and antioxidant benefits, a dosage of 300–600 mg of green tea extract (GTE) daily, standardized to 50% EGCG, is generally recommended. A minimum effective dose is around 250–300 mg GTE daily. While up to 800 mg GTE daily is considered safe for most adults, higher doses may increase the risk of side effects. It is best taken in the morning or early afternoon to avoid sleep disruption. Capsules or standardized extracts allow for precise dosing, while brewed tea is suitable for general consumption. Taking it on an empty stomach can optimize catechin absorption. No specific cofactors are required, though vitamin C may enhance catechin stability.
FAQs
Is jasmine green tea safe?
Jasmine green tea is safe for most adults in moderate amounts. Monitor for caffeine sensitivity and potential interactions with medications. If you have liver issues, consult your healthcare provider.
When is the best time to drink jasmine green tea?
It is best to consume jasmine green tea in the morning or early afternoon to avoid sleep disruption due to its caffeine content. Avoid late-day consumption.
What are the expected benefits of jasmine green tea?
Expect modest improvements in body composition and oxidative stress after 8–12 weeks of regular consumption. Benefits are primarily from the green tea base, not the jasmine.
Is jasmine green tea different from regular green tea?
Jasmine green tea is not significantly different from regular green tea in terms of health effects. The primary difference is the added aroma from jasmine flowers.
Research Sources
- https://pubmed.ncbi.nlm.nih.gov/38031409/ – This systematic review and meta-analysis of 59 RCTs (n=3,802) found that green tea extract (GTE) supplementation significantly reduced body mass (BM), body fat percentage (BFP), and BMI, while also increasing total antioxidant capacity (TAC) and adiponectin. The study highlights the potential of GTE in improving body composition and reducing oxidative stress, although it notes heterogeneity in study designs and populations.
- https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2022.1084455/full – A meta-analysis of 40 clinical trial arms indicated that green tea consumption reduced triglyceride levels in studies lasting longer than 12 weeks and including both sexes. The study suggests that the duration of green tea intervention is a critical factor in observing its beneficial effects on cardiovascular risk factors, specifically triglycerides.
- https://www.mdpi.com/2306-5710/2/2/16 – This systematic review focused on the effects of green tea catechins on anthropometric and metabolic markers in adults with overweight or obesity. The review found that green tea catechins modestly improved these markers, suggesting a potential role in weight management and metabolic health, though it acknowledges variability in interventions and outcomes.
