I thought people often workout or exercise need slightly higher vitamin D level?
Quite possible, but as Boxcar was noting, we found research showing that as it gets into the 40s ng/mL, vitamin D is associated with decreasing testosterone. And PeakT points to the link to higher mortality as you get into the 50s.
The other issue is that we're lacking evidence of benefits from forcing vitamin D to a particular level via supplementation. Ongoing studies should tell us more.
