My DHEA-S levels after supplementing with 1 x 50mg slow release caps per day came back at 700 mcg/dL. So I did some looking around.
It looks like it is a bit too high which can cause other disruptions - see below

If you google a link to LEF and another link (Dr jack Kruse), you will see a couple of good articles.

LEF have their ideal range at 350 – 490 mcg/dL = (9 – 13 umol/l)
Dr Jack Kruse – 500 – 640 mcg/dL = (13 – 16 umol/l)

My level is 700 supplementing with 50mg/d, so I will halve it.
It seems I ought to aim for the 350 - 400 mark, as higher may have unwanted side effects such as prostate related issues.
