Ashwagandha, also known as Withania somnifera, is a popular adaptogenic herb that has been used for thousands of years in Ayurvedic medicine. The root of the plant is rich in active compounds such as alkaloids, flavonoids, and withanolides, which are believed to be responsible for its medicinal properties.
In recent years, ashwagandha root extract capsules have gained popularity as a natural supplement for managing stress, and anxiety, and improving overall health. But what does science say about its benefits? Let's take a look at some of the studies.
Stress and Anxiety Relief
One of the most well-known benefits of ashwagandha is its ability to reduce stress and anxiety. In a randomized, double-blind, placebo-controlled study published in the Journal of Clinical Psychopharmacology, 64 adults with a history of chronic stress were given either a placebo or ashwagandha root extract for 60 days. The group taking ashwagandha showed a significant reduction in perceived stress and anxiety compared to the placebo group.
Another study published in the Indian Journal of Psychological Medicine found that ashwagandha root extract was effective in reducing anxiety and depression in 64 adults with a history of chronic stress. The participants taking ashwagandha had significantly lower levels of the stress hormone cortisol and reported improvements in sleep quality.
Improving Brain Function
Ashwagandha has also been shown to have neuroprotective properties and may improve brain function. In a study published in the Journal of Dietary Supplements, 50 adults with mild cognitive impairment were given either a placebo or ashwagandha root extract for eight weeks. The group taking ashwagandha showed significant improvements in memory, attention, and information processing compared to the placebo group.
In a separate study published in the Journal of Ethnopharmacology, ashwagandha was found to protect against brain damage caused by oxidative stress. The study was conducted on rats, but the results suggest that ashwagandha may be beneficial in preventing neurodegenerative diseases in humans.
Anti-Inflammatory and Immune-Boosting Properties
Ashwagandha also has anti-inflammatory and immune-boosting properties. In a study published in the Journal of Ayurveda and Integrative Medicine, ashwagandha root extract was found to significantly reduce markers of inflammation in 25 adults with osteoarthritis. The participants taking ashwagandha reported a reduction in pain and stiffness compared to the placebo group.
Another study published in the Journal of Ethnopharmacology found that ashwagandha root extract was effective in boosting immune function. The study was conducted on mice, but the results suggest that ashwagandha may be beneficial in supporting immune health in humans.
Dosage and Safety
While ashwagandha root extract capsules are generally considered safe, it is important to follow the recommended dosage and speak with your healthcare provider before taking any new supplement. The recommended dosage of ashwagandha root extract is typically 250-500mg per day.
Ashwagandha root extract capsules have been studied extensively for their potential health benefits. The research suggests that ashwagandha may be effective in reducing stress and anxiety, improving brain function, and boosting immune health. However, more research is needed to fully understand the potential benefits and risks of ashwagandha. If you're interested in trying ashwagandha root extract capsules, be sure to speak with your healthcare provider to determine if it's right for you.
