Medium roast Peruvian decaf blended with organic reishi and chaga extracts. Four Sigmatic's formula aims for stress relief and calm without the jitters—use 4 Tbsp per 12 oz of water. Third-party tested for heavy metals, mycotoxins, mold, yeast, and pesticides.
Individual adaptogenic herbs (ashwagandha, rhodiola) show modest RCT support for stress and fatigue outcomes, and coffee polyphenols have observational links to cardiovascular and metabolic health. However, the blend as a formulation has not been studied, and adaptogen efficacy varies widely by dose, extract type, and population. The decaffeination removes caffeine's well-established cognitive benefits, which is a trade-off worth noting.
Adaptogens are plant compounds proposed to help the body resist physical, chemical, or biological stress by modulating the hypothalamic-pituitary-adrenal (HPA) axis and stress hormone levels. Common adaptogenic ingredients (ashwagandha, rhodiola, eleuthero) contain bioactive compounds like withanolides and phenolic acids that may influence cortisol, ACTH (adrenocorticotropic hormone), and immune function. Decaffeination removes caffeine's stimulant effects, potentially reducing jitteriness while preserving other coffee polyphenols.

Observational
“BACKGROUND: Ashwagandha (Withania somnifera (L.) Dunal) is a herb traditionally used to reduce stress and enhance wellbeing.”
“BACKGROUND: The coronavirus disease-2019 (COVID-19) pandemic has resulted in a surge in stress, anxiety, and depression worldwide.”
“Chronic stress has been associated with a number of illnesses, including obesity.”
“PURPOSE OF REVIEW: Tea and coffee, after water, are the most commonly consumed beverages in the world and are the top sources of caffeine and antioxidant polyphenols in the American diet.”
Most adaptogen RCTs are small (N < 100), often conducted in Asia with limited replication in Western populations. The 'adaptogenic' category itself lacks a unified biomarker or consensus definition—regulatory agencies do not formally recognize it. Blended formulations are rarely tested as a unit; efficacy claims rest on individual ingredient studies. Decaffeinated coffee loses caffeine's proven acute alertness and endurance benefits. Quality and standardization of adaptogenic extracts vary widely across brands.
