I've been taking similar quantities in years and my WellnessFX labs and annual physicals are perfect. Even if supplements are not help me (much), they are not hurting me (much) either although it's hard to tell as often damage accumulates over years and labs only expose a few pixels of the whole picture.

If you can't tell, or it's hard to tell, over years, then why go through all the trouble and expense?

Well, maybe I'd be getting worse if I wasn't taking them... How can I know, right? :)

Science demands you double blind placebo test!
