Organic Matcha Green Tea Leaf Powder
Also known as: Matcha Green Tea, Green Tea Powder, *Camellia sinensis*
Overview
Matcha is a finely ground powder derived from the leaves of the *Camellia sinensis* plant, which is notably used for making various tea types. This unique tea is typically shade-grown, enhancing its chlorophyll and L-theanine content, which significantly improves its flavor and nutritional benefits. Matcha is regarded as a potent dietary supplement, rich in antioxidants like EGCG (epigallocatechin gallate), caffeine, and L-theanine. These compounds contribute to its use as a beverage, food ingredient, and supplement, promising potential health benefits. The body of research on matcha is substantial, including randomized controlled trials (RCTs) and meta-analyses covering cardiovascular and metabolic health, confirming many of its health claims.
Benefits
Matcha is associated with several health advantages backed by research. Significant benefits include its ability to improve cardiovascular health, as evidenced by a meta-analysis indicating reduced LDL cholesterol and increased HDL cholesterol. It also aids in lowering blood pressure and improving glycemic control, with evidence from well-structured studies. Secondary effects include weight loss through increased energy expenditure and a reduced risk of certain cancers; meta-analyses demonstrate lower breast, colon, and prostate cancer risks. Additionally, the cognitive benefits from the combination of caffeine and L-theanine are well-documented, with studies indicating improvements in focus, mood, and reduced fatigue.
How it works
The mechanism of action of matcha primarily involves its active component, EGCG, which enhances energy expenditure and promotes fat burning through mechanisms like thermogenesis and lipolysis. It also modulates lipid profiles and blood pressure, making it beneficial for cardiovascular health. The synergy between caffeine and L-theanine enhances mental alertness and relaxation, thus positively impacting cognitive function. The bioavailability of catechins is significantly higher in matcha than in brewed green tea, as whole leaves are consumed in powder form, maximizing their therapeutic effects.
Side effects
Matcha is generally safe when consumed in moderation; common side effects are rare. However, individuals sensitive to caffeine may experience jitteriness, anxiety, or insomnia, particularly at high doses. Uncommon side effects include gastrointestinal discomfort and allergic reactions, which are rare. While there are no well-documented significant rare side effects, caution is advised when consuming matcha alongside certain medications, particularly blood thinners, as catechins may interact adversely. Contraindications include high caffeine intake for pregnant individuals, children, and those with certain cardiovascular conditions. Older adults and those with sensitive digestive systems should consult healthcare providers regarding matcha consumption.
Dosage
For cardiovascular benefits, a minimum effective dose is 250-500 mg of catechins per day, achievable with 1-2 cups of matcha tea. Generally, 1-3 cups of matcha daily is recommended for health benefits, translating to about 1.5-3 grams of matcha powder. While no established maximum safe dose exists, excessive consumption (more than 5 cups/day) may lead to high caffeine intake. Timing of consumption is flexible, although mornings or early afternoons are preferable to avoid sleep disturbances. Furthermore, matcha powder tends to have superior bioavailability than brewed tea due to whole leaf consumption. It's important to stay hydrated and maintain a balanced diet to optimize benefits.
