Discover the Science Behind the Benefits of Ashwagandha
Share
Ashwagandha, also known as Withania somnifera, is an ancient medicinal herb that has been used for centuries in Ayurvedic medicine. It is known for its adaptogenic properties, which means it helps the body adapt to stress and promotes overall well-being. But what is the science behind the benefits of Ashwagandha? Let's dive into the research and explore the evidence behind this powerful herb.
1. Reduces Stress and Anxiety
One of the most well-known benefits of Ashwagandha is its ability to reduce stress and anxiety. Several studies have shown that Ashwagandha can lower cortisol levels, a hormone that is released in response to stress. In a randomized controlled trial, participants who took Ashwagandha experienced a significant reduction in stress and anxiety compared to those who took a placebo.
2. Improves Cognitive Function
Ashwagandha has also been shown to improve cognitive function. In a study published in the Journal of Dietary Supplements, participants who took Ashwagandha for 8 weeks showed significant improvements in memory, attention, and information processing compared to those who took a placebo. This may be due to the herb's antioxidant properties, which help protect the brain from oxidative stress.
3. Boosts Immune System
Ashwagandha has been found to have immunomodulatory effects, meaning it can help regulate and strengthen the immune system. In a study published in the Journal of Ethnopharmacology, researchers found that Ashwagandha increased the activity of natural killer cells, which are responsible for fighting off infections and cancer cells. This suggests that Ashwagandha may help enhance immune function and protect against illness.
4. Supports Sexual Health
Ashwagandha has long been used as an aphrodisiac in traditional medicine. Recent studies have shown that it may indeed have positive effects on sexual health. In a study published in the Journal of Sexual Medicine, men who took Ashwagandha experienced improved sperm quality and increased testosterone levels. Additionally, women who took Ashwagandha reported increased sexual satisfaction and arousal.
5. Manages Blood Sugar Levels
Research suggests that Ashwagandha may help manage blood sugar levels, making it beneficial for individuals with diabetes or prediabetes. In a study published in the Indian Journal of Experimental Biology, participants who took Ashwagandha for 30 days showed a significant reduction in fasting blood sugar levels. Ashwagandha may also improve insulin sensitivity, which can help regulate blood sugar levels.
Science Behind Ashwagandha
- Ashwagandha for Vitality - Overweight men aged 40–70 years with mild fatigue were given a placebo or an ashwagandha extract for eight weeks (Source).
- Ashwagandha for Anxiety - Five studies concluded that ashwagandha intervention resulted in greater score improvements (significantly in most cases) than placebo in anxiety or stress scale outcomes (Source).
- Ashwagandha for Sleep - The study confirms that Ashwagandha root extract can improve sleep quality and help manage insomnia. All study participants tolerated Ashwagandha root extract well, irrespective of their health condition and age (Source).
- Ashwagandha for Mood - Administration of Ashwagandha (Noogandha) supplements daily improves physiological, cognitive, and psychological stress response over a 30-day period (Source).
- Pepper for Effect Increase - Piperine increases the bioavailability of different drugs ranging from 30% to 200%. Subsequent research has shown that it increases curcumin bioavailability by almost ten-fold (Source).
Overall, the science behind the benefits of Ashwagandha is promising. However, it's important to note that more research is needed to fully understand its mechanisms of action and potential side effects. If you're considering incorporating Ashwagandha into your wellness routine, it's always best to consult with a healthcare professional to ensure it's safe for you.
