I am one month short of 50.
Plazma. Doesn't matter your goal. Plazma. And sorry, but at my age, I find it to be a "needed" supplement. Yeah, you can do without, but the upside is way to good too ignore.
The rest, as noted above, not needed. I do find Omega's (Flameout) quite helpful (overall health and joint health).
The rest depends on your goal(s).
