The Science

The science, not the hype

We make coffee — real arabica, whole bean and instant — and we blend some of it with functional mushrooms. We would rather show you what the research actually says than make big promises. Here is an honest look at the ingredients we use, with sources you can read yourself.

Coffee & caffeine

Coffee is one of the most-studied things you can drink. It is naturally rich in polyphenol antioxidants, which help counter the oxidative stress that builds up in the body, and its caffeine is a well-established way to support alertness, concentration, and focus. Harvard’s Nutrition Source notes that moderate coffee intake — roughly one to five cups a day — is associated with a range of benefits, with or without caffeine. (Harvard T.H. Chan School of Public Health)

Matcha: caffeine + L-theanine

Shade-grown green tea is unusual because it delivers caffeine alongside an amino acid called L-theanine. In controlled studies, that pairing is linked to what researchers call “relaxed alertness” — improved attention and task-switching with less of the jittery edge caffeine alone can bring. It is the reason a bowl of matcha tends to feel steadier than a strong cup of coffee. (Nutritional Neuroscience)

Lion’s mane

Lion’s mane (Hericium erinaceus) is an edible mushroom that has become one of the more interesting subjects in nutrition research. Early randomized, placebo-controlled trials have reported improvements in visual attention, working memory, and mood, and laboratory work points to its effect on nerve growth factor (NGF). The honest caveat: these human trials are still small and short, and larger studies are needed before anyone can claim more. (Frontiers in Nutrition, 2025; Alzheimer’s Drug Discovery Foundation)

Chaga

Chaga (Inonotus obliquus) has been brewed as a tea for centuries. Modern lab research has isolated antioxidant compounds — polysaccharides, triterpenoids, and polyphenols — and shown antioxidant and anti-inflammatory activity in cell and animal studies. Most of that evidence is still preclinical, so we treat it as promising traditional-use context rather than a proven benefit. (Therapeutic properties of Inonotus obliquus, 2024 review)

How we think about claims

Coffee and caffeine have decades of solid human research behind them. Lion’s mane and chaga are earlier in that journey — genuinely promising, but not settled. We will keep our language honest as the science develops, and we will always point you to the source.
