Quick Answer
Olive Leaf Extract Sleep Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Results At day 60, both VL-G-A57 and VL-G-E12 significantly reduced Perceived Stress Scale (PSS) scores compared to placebo (p Conclusion The study concluded that both VL-G-A57 and VL-G-E12 were associated with reductions in stress, fatigue, and anxiety while improving mood and sleep quality.
Key Takeaways
- 01Results At day 60, both VL-G-A57 and VL-G-E12 significantly reduced Perceived Stress Scale (PSS) scores compared to placebo (p Conclusion The study concluded that both VL-G-A57 and VL-G-E12 were associated with reductions in stress, fatigue, and anxiety while improving mood and sleep quality. [McKinney E (2026)]
- 02Background Chronic stress is detrimental to the maintenance of the main response system - the hypothalamic-pituitary-adrenal (HPA) axis. [McKinney E (2026)]
- 03The current study aimed to investigate the efficacy of two plant-based adaptogens, a formula containing Rhodiola, holy basil and Schisandra chinensis (VL-G-A57) and a full-spectrum ashwagandha (VL-G-E12), on stress and related symptoms in individuals with high stress. [McKinney E (2026)]
- 04Following a nutritious, well-balanced diet has been found to lower the risk of depression [], whereas consuming diets high in processed and sugary foods and low in fiber and healthy fats correlates with a higher risk of depression [,,,]. [Martínez-Zamora Lorena (2025)]

- 13 14 15 One of the most important phytochemicals found in olive by-products is hydroxytyrosol (HXT), which has garnered attention during the last twenty years due to its important health benefits. [Martínez-Zamora Lorena (2025); evidence level 3]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
