Ashwagandha Boosts Mood, Sleep, and Brainpower.

Ashwagandha, a powerful herb used in traditional medicine, has been shown in a 2025 review to help reduce stress, fatigue, anxiety, and depressive symptoms. It also supports better sleep and sharper mental focus, boosting overall feelings of well-being—even for older adults aged 60–85.

The review highlights multiple human and animal studies, including a 12-week trial in older individuals taking 600 mg daily of ashwagandha extract, which led to noticeable improvements in sleep quality and mental alertness. In lab and mouse trials, specific extracts increased restorative non-REM sleep. Ashwagandha appears to balance cortisol and inflammation, enhance antioxidant defenses, and promote healthy sleep patterns and cognitive resilience.

If you’re dealing with stress, fatigue, poor sleep, or brain fog, consider trying a quality ashwagandha supplement (600 mg daily)—it could be a natural game-changer.
