THANKS Chrisb1.

Chrisb1 hope you are well and thanks for this.

Is anyone trying to "map" all these nutritional associations?

Recognising individual variability and the "status" of the supplement would need to be part of the mapping.

Perhaps that may be too big a task but the idea is deeply attractive. Just knowing a "baseline" reference point was available could be great. Perhaps using the net in a constructive way (being able to weed out the commercial sector??) may make that task easier.

Probably a messy wish of mine.
