You're getting 500mg of **Relora** — a patented magnolia and phellodendron bark blend — right at the standard dose used in the two clinical trials that showed reduced self-reported stress and anxiety. At one capsule daily, you're hitting the clinical range without needing to split doses throughout the day, which is convenient for a stress-support product.

The formula also includes 100mg of **Oligonol**, a lychee-derived polyphenol extract. This sits at the minimum dose from a single small study on exercise-induced cortisol, but there are no human trials testing it for everyday psychological stress. Its role here is more speculative than proven.

The honest caveat: both ingredients carry limited clinical evidence. **Relora** has only two small, manufacturer-funded trials, and **Oligonol** has just one. The stress-reduction results are based on self-reported questionnaires rather than objective cortisol measurements, so the "cortisol balance" in the name oversells what the research actually showed.
