Green Tea leaf extract

Green tea has been studied extensively over the years, and is widely recognized for supporting longevity and health aging in Asian countries with regular consumption. Perhaps the most well studied and familiar compound, caffeine is a naturally occurring alkaloid found in several plant species, commonly in high abundance in tea leaves and coffee beans. Unlike synthetic versions, natural caffeine from green tea, delivers a slow, metered release of caffeine, and has natural synergistic ingredients like L-theanine that counteracts “jitters” or anxious feelings associated with caffeine intake.


Healthy aging
Support healthy inflammation response
Promote longevity
Improve energy
Reduce stress
Improve cognition

How it works:

Green tea is high in bioactive polyphenols, such as the natural catechin known as ECGC. These have many targets within the body, with strong clinical research to support both cardiovascular health and a healthy inflammation response, two key indicators of longevity and healthy aging. Recent clinical studies have shown that polyphenols, such as ECGC, are capable of crossing the blood-brain barrier and provide neuroprotective effects that help with cognition during aging.

Caffeine stimulates the release of neurotransmitters and has been shown to aid in energy levels, cognition, focus, and reaction time, during presence of stress.

Safe and Effective Dosage:

Dosages and historic use have varied widely in research, with safe dosages of polyphenols over 4,000 mg per day.

Our dosage:

135 mg (44 mg polyphenols, 22 mg EGCG, 45 mg caffeine). This is roughly equivalent to 1 cup of green tea.





"Beneficial effects of green tea: A literature review"


The health benefits of green tea for a wide variety of ailments, including different types of cancer, heart disease, and liver disease, were reported. Many of these beneficial effects of green tea are related to its catechin, particularly (-)-epigallocatechin-3-gallate, content.

There is evidence from in vitro and animal studies on the underlying mechanisms of green tea catechins and their biological actions. There are also human studies on using green tea catechins to treat metabolic syndrome, such as obesity, type II diabetes, and cardiovascular risk factors.

Long-term consumption of tea catechins could be beneficial against high-fat diet-induced obesity and type II diabetes and could reduce the risk of coronary disease.

Further research that conforms to international standards should be performed to monitor the pharmacological and clinical effects of green tea and to elucidate its mechanisms of action.

"Psychological effects of dietary components of tea: caffeine and L-theanine"


This review summarizes the literature on the association between two dietary components of tea, caffeine and L-theanine, and the psychological outcomes of consumption; it also identifies areas for future research.

The studies reviewed suggest that caffeinated tea, when ingested at regular intervals, may maintain alertness, focused attention, and accuracy and may modulate the more acute effects of higher doses of caffeine.

These findings concur with the neurochemical effects of L-theanine on the brain. L-theanine may interact with caffeine to enhance performance in terms of attention switching and the ability to ignore distraction; this is likely to be reflective of higher-level cognitive activity and may be sensitive to the detrimental effects of overstimulation.

Further research should investigate the interactive effects of caffeine, L-theanine, and task complexity, utilize a range of ecologically valid psychological outcomes, and assess the neuroprotective effects of L-theanine using epidemiological or longer-term intervention studies among individuals at risk of neurodegenerative disease.
