How it works
Maintain -- EGCG is among the most potent dietary catechin free-radical scavengers, also chelating pro-oxidant metal ions
Transform -- studied for modest effects on fat oxidation and metabolic rate, likely via catechol-O-methyltransferase interactions
Adapt -- activates Nrf2 antioxidant-response signaling similar to other polyphenols
Process -- green tea's combination of EGCG and L-theanine is studied for calm-alertness and attention, a Process-relevant cognitive effect
Form matters
The same nutrient can be made in very different forms -- and a study done on one form does not automatically apply to another. Methylcobalamin is not cyanocobalamin; magnesium glycinate is not magnesium oxide; a whole-food extract is not the synthetic isolate that was studied. Two things decide whether what is in the bottle behaves like the research: the exact form, and independent lab verification (a Certificate of Analysis) that the form and dose on the label are truly what is inside. Without a COA, you are trusting a label, not the science.

- NutrientGreen Tea, EGCG, and the Case for a Real DoseGreen tea's benefits trace mostly to polyphenols, especially the catechin EGCG. Research associates them with how the body handles heavy metals, healthy metabolism, and lower cancer risk in population studies -- association, never proof. The catch is dose: getting a therapeutic range from brewed tea can mean roughly 7 cups a day.8 min read
- NutrientHow Do I Support My Immune System Without Simply "Boosting" It?A human meta-analysis found green tea supplementation lowered TNF-alpha but showed no clear effect on CRP or IL-6, which is modulation rather than a uniform boost. A year-long trial in postmenopausal women found high-dose extract changed none of the three versus placebo. The reliable supports remain sleep, protein, movement and barrier health.4 min read
- NutrientWhat Actually Raises Metabolism and Fat Oxidation?Green tea's catechins interact with real fat-metabolism pathways, but the human effect on body fat is small and dose-dependent. A trial using 583 mg of catechins daily saw greater body-fat reduction than a lower-catechin control, while a meta-analysis found only small additional weight loss on top of exercise.4 min read
