Study, Trial or Testing Result Summary
Members OnlyHuman studies
No study in people has tested Java tea for aging, cell repair or DNA repair, and no study has measured biological age or any aging marker in humans taking it [1]. The only related research is a 2019 mouse study. It used rosmarinic acid, a single compound taken from Java tea extract, rather than the whole tea. In those mice the compound protected the gut lining from damage caused by a high-fat diet, lowered oxidative stress (chemical wear on cells linked to aging) and reduced cell death in the gut lining [1]. The study did not report how many animals were used, how long it lasted or what dose was given, so it cannot be compared with this product [1]. This product is a whole Java tea liquid extract at 0.13 milliliters per serving, and how much rosmarinic acid that supplies is not stated. Because the research was done only in animals with one isolated compound, it is not known whether taking this supplement would have any effect on aging or cell repair in people [1]. Animal and cell studies are never counted.

RAL Summary
Members OnlyTier 4 for Healthy Aging
The only study cited tested isolated rosmarinic acid in mice, not a whole Java tea extract like this product, so there is no real study support for this goal and the tier should be 4. So it is graded Tier 4, lower than the rules alone gave.
- Emerging: not enough evidence to rank higher yet.
