I've been using the capsules and the powder for over a year now. I discovered the product while looking for natural and effective cancer fighters. I'm 54 and now I have abundant energy, running 6 miles 2-3 times a week. All inflammation is almost 90% gone ( mind you i beat my body at work and at the gym regularly.) The results come slowly but at some point you realize that you just feel better and the symptoms, illnesses have subsided. I take it daily for over a year now. 4 to 6 capsules a day. I also use omega 3s, pychnogenol, zinc, mushroom extracts and many other supplements. Customer service is also great. I had an issue with a shipment, and they immediately replaced the products
