alt Hacker NewsI started back on Vitamin-D and Omega-3 (with extra EPA & DHA) about 2 months ago or so. Sadly, I don't feel much of a difference, but I believe the potential harms are quite minimal, so I am going to maintain supplementation for the purposes of self-experimentation.
It took me more than 3 months to get to the lower edge of the desired range with my blood level on about 8000 UI daily. There was no instant improvement, it takes time.
Do keep your levels in check though.
