Ceremonial-grade matcha grown in Grandma Keiko's own garden in Japan — harvested once a year by her granddaughter Yuki. 100% pure. 0% sugar. The same daily ritual that's kept her mind sharp for over a century.
As we age, cognitive changes can affect our daily quality of life. If you've noticed any of these signs, you're not alone — and there may be natural ways to support your brain.
Millions of Americans experience age-related changes in memory and cognitive function. Meanwhile, Japan has one of the lowest rates of cognitive decline in the world — and one of the highest rates of daily matcha consumption. Coincidence? Research says probably not.
Grandma Keiko is 103 years old. She still lives independently, cooks her own meals, and has a memory that puts people half her age to shame. Her secret? A bowl of matcha every single morning — made from the tea leaves grown in her own garden in Japan.
Grandma Keiko's tea garden in Japan — where every tin of Secret Matcha comes from.
Matcha contains a unique combination of natural compounds studied in peer-reviewed research for their effects on cognitive function:
Matcha contains 5x more L-Theanine than regular green tea. This amino acid crosses the blood-brain barrier and promotes alpha brain wave activity — the same pattern associated with calm, focused attention. Studies show L-Theanine may support attention, memory, and mental clarity without the jitteriness of coffee.*
Epigallocatechin gallate (EGCG) is the most abundant catechin in matcha. Research in the Journal of Nutritional Biochemistry suggests EGCG may help protect neurons from oxidative stress, support brain blood flow, and promote healthy brain cell signaling.*
Unlike steeped green tea (where leaves are discarded), matcha means consuming the entire leaf ground to a fine powder. This delivers up to 137x the antioxidant concentration of regular green tea, according to a study in the Journal of Chromatography.*
Not all brain support is created equal. Here's how Secret Matcha stacks up.
