Organic Matcha

Also known as: Matcha Green Tea, Green Tea Powder, Camellia sinensis, Camellia sinensis (Matcha)

Overview

Matcha is a finely ground powder made from the leaves of the *Camellia sinensis* plant. It is a type of green tea known for its high concentration of antioxidants, particularly catechins, and other beneficial phytochemicals like chlorophyll and quercetin. Matcha is consumed as a beverage, added to foods, and used in dietary supplements. It is characterized by its high levels of antioxidants, caffeine, and L-theanine. Research on matcha and its components is ongoing, with numerous studies exploring its potential health benefits. The quality of available evidence is generally high, with several systematic reviews and meta-analyses providing robust support for its effects. Due to the ingestion of the entire leaf, the powdered form may enhance absorption compared to brewed green tea.

Benefits

Matcha offers several evidence-based benefits. Consumption is associated with significant reductions in systolic and diastolic blood pressure, with a meta-analysis reporting reductions of -2.08 mm Hg (95% CI -3.06, -1.05) and -1.71 mm Hg (95% CI -2.86, -0.56), respectively. It is also linked to improvements in lipid profiles, including reductions in total cholesterol (-0.15 mmol/L [95% CI -0.27, -0.02]) and LDL cholesterol (-0.16 mmol/L [95% CI -0.22, -0.09]). The polyphenols in matcha, especially catechins, provide anti-inflammatory and antioxidant effects. L-theanine in matcha may improve concentration and alertness, and it has been shown to increase maximum leg strength, reduce subjective fatigue after exercise, and enhance skeletal muscle mass in response to training. The cardiovascular benefits are more pronounced in individuals with higher baseline blood pressure (≥ 130 mm Hg).

How it works

Matcha's beneficial effects are primarily attributed to its high concentration of catechins, especially epigallocatechin gallate (EGCG), which interact with various biological pathways. These pathways include antioxidant defense mechanisms, inflammation reduction, and modulation of lipid metabolism. Matcha affects the cardiovascular system by improving blood pressure and lipid profiles. L-theanine influences the nervous system, potentially enhancing alertness and concentration. Catechins target molecular pathways involved in inflammation and oxidative stress. The powdered form of matcha may enhance absorption compared to brewed green tea due to the ingestion of the entire leaf.

Side effects

Matcha is generally considered safe when consumed in moderate amounts. Common side effects, occurring in more than 5% of users, are primarily caffeine-related, including jitteriness, insomnia, and increased heart rate, especially in sensitive individuals. Uncommon side effects (1-5%) may include gastrointestinal upset, such as nausea or stomach discomfort. Rare side effects are not well-documented, but high doses of caffeine can lead to more severe adverse effects. The catechins and caffeine in matcha may interact with certain medications, such as blood thinners and stimulants. High caffeine content may be contraindicated in pregnant women, children, and individuals with certain heart conditions. Pregnant or breastfeeding women, children, and individuals with caffeine sensitivity should consume matcha with caution.

Dosage

The minimum effective dose for cardiovascular benefits is not well-defined, but typical consumption ranges from 1-2 teaspoons (about 2-4 grams) per day. For cardiovascular health, consuming 2-3 cups of green tea or 1-2 teaspoons of matcha powder per day is often recommended. The maximum safe dose is not strictly defined, but high caffeine intake (>400 mg per day) should be avoided. Matcha can be consumed at any time, but avoiding it close to bedtime is recommended due to its caffeine content. The powdered form of matcha may offer better bioavailability compared to brewed green tea. The absorption of matcha's components can be influenced by the presence of other nutrients, such as fats and proteins.

FAQs

Is matcha safe to consume?

Matcha is generally safe, but high caffeine intake should be avoided, especially in sensitive populations like pregnant women, children, and individuals with heart conditions.

When is the best time to consume matcha?

It is best to consume matcha in the morning or early afternoon to avoid disrupting sleep due to its caffeine content. Avoid consuming it close to bedtime.

What are the expected benefits of consuming matcha regularly?

Regular consumption may lead to improvements in cardiovascular health, such as reduced blood pressure and improved lipid profiles. Individual results can vary based on overall health and lifestyle.

Is matcha a weight loss supplement?

Matcha is not a magic bullet for weight loss, although it may contribute to these benefits as part of a balanced lifestyle. It can support overall health and well-being.
