What You Can Read Here
Start with ergothioneine, equol, or collagen peptides if you want to understand an ingredient. Readers familiar with the research can explore the HPA axis, mitochondria, autophagy, and zebrafish-based formulation screening.
How is ergothioneine transported? How is equol related to soy isoflavones? In what form are collagen peptides absorbed? Start with a specific ingredient.
The recovery series explores the genome, telomeres, autophagy, mitochondria, cellular senescence, and inflammation resolution.
Read about zebrafish models, formulation screening, and cocrystal technology, including study methods, ingredient stability, and formulation applications.
CONTENT PRINCIPLES
How Do You Read a Study?
A research finding may come from a cell experiment, an animal model, or a human observational or intervention study. First look at how the study was done, then consider how it relates to your question.
Who or What Was Studied?
Cell, animal, and human studies answer different questions. Findings about an ingredient cannot be assumed to apply to a finished formulation containing it.
What Dose and Duration Were Used?
How much of the ingredient was used, for how long, and what was measured? These details help establish what a result can tell you.
Distinguish Measurements from Experience
Feeling better is a personal experience; blood markers, sleep scores, and skin measurements are specific observations. Look at what the study actually recorded.
