I'm a 64-year-old man who's used Basis for a month. I've noticed a few changes. I am sleeping more deeply, I'd say 20% better.
Another thing struck me. I don't usually run and haven't for, I'm guessing, a year. The air quality here has been poor all summer. We finally had a cooler day with good air last week. Usually, when I haven't run I go one mile and do okay. This time, when I hit the one-mile mark I kept going and ran two miles. I was a little sore the next day and more sore the second day, as is usual. (I also hiked about 7 miles up and down hills on the second day.) But to run an extra mile was unusual. At the time, it felt totally normal.
So I think something is happening but I don't know what it is.
Bottom Line: Yes, I would recommend this to a friend
