BETTER BUT WITH SIDE EFFECTS
I experment with it now and then and find that it does have an effect.. Most notably on inflammation.. (for myself).. However initially found it affected my digestion. (diarrhea) I also take it with a multi cartenoid. Since it is just one of hundreds of beneficial cartenoids.. With this one it is good to take breaks since there are no long term studies. & better not to overdue it. I just take one 4mg at bedtime.. There are a few supplements and herbs I seem to go back to and this is one.. But as you see in the posts here it's affects depend on the individual...
