Guys, Great thread.
I love this herb more than any other botanical/adaptogen I have tried so far. I have been using ashwagandha for last 4 years. I started initially with Himalaya Ashwganadha and felt nice. Then switched to sensoril, since it is clinically shown to reduce stress. However, I never found it do any positive effects on me. Rather, it created bloating in me and I had to discontinue after a couple of weeks. I returned to Himalaya, until I came across Nutrigold ashwagandha last year. Since it was the only other clinically proven ashwagandha besides sensoril, I wanted to give it a try (I have always been inclined to using branded ingredients as they are clinically proven to show the effects).
I believe that KSM-66 is a miraculous supplement for me. I started to feel the effects after 3 weeks of use or so. When I take in the morning, it gives me energy to run a marathon and when I take in the night, puts me to sleep like that of a baby. Nothing had ever worked for me so good as this supplement. This created a lot of inquisitiveness in me and I ended up doing quite a lot of search on ashwagandhas. I think what really sets KSM-66 aside is that it is a full spectrum root extract. Not only traditionally, roots extracts have been recommended, but all the modern clinical studies have used roots. Even the pharmacopeias and regulatory bodies the world over suggest the usage of roots (USP, Britain, India, Canada). The makers claim that they do not use any alcohol for extraction and make the highest potency extract on the market. That might be an another advantage. It is also organic. I recommended this product to my family, and my sister and mother equally love it. I would strongly recommend this product. However, I also believe that it should be taken along with another ingredient called Zembrin for the best effects. There is a product I now take called Zembrin Mood Plus, which combines KSM-66 with Zembrin, and it has been the best so far.
