I know there have been threads discussing short breaks... but specifically to the initial question: Do you believe that most exogenous supplements lose their effectiveness after 6-12 months of continued use? That could be a reason to take such a long break and possibly find an alternate vector. I can only imagine none of the usual cast here believes this as I don't recall (or find it in a search) anyone bringing it up.
That is a good question. Some drugs lose their effectiveness after continued use (some hormones, CNS drugs etc.) the issues are very complicated and due to receptors being up or down regulated, feedback loops, enzymes being increased or decreased etc. Ones body want to return to homeostasis. I think we need some of the biochemists on the board to give us some more info on the subject with regards to supplements.
From my perspective, I am trying to take things that have been shown in long term studies to be beneficial for human populations and in Rats and other Mammals to be beneficial for years which translates to decades in humans.
There are supplements that I know of that supposedly showed beneficial measurable results long after supplementation ended. Bacopa and the ALCAR/ALA stack on cognitive functioning. So theoretically one could take a longer break from some supplements and still have benefits and then restart the supplments with one's body maybe being more sensitive to them... or in the time that you stopped taking them you could also accumulate more age related damage. I think for supplements like AGE blockers taking them most every day (multiple times per day) without cycling is a good thing as they are preventing the accumulation of damage, for other supplements maybe a longer break might be good.
For now ill stick with my mini breaks until I see some evidence. Its an interesting discussion though and maybe worth looking into but I think that it will have to be done on a supplement by supplement basis.
There is a guy on here JamesGreen who is really into the whole Telomerase idea and copying the TA-65 protocol which apparently does a lot of one month on one month off and the sort of cycling you are talking about maybe you should PM him and see his ideas.
http://www.imminst.o...reen-m4099.html I not a believer, I've only talked to him to get his ideas on Astragalus/Astragalosides as telomerase enhancers, but he might give you a different perspective. I think he does things like two weeks of a SIRT Resveratrol based program then stops that and does two weeks of an Astragaloside Telomerase program and a month on and a month off of other things. Seemed way too complicated to me.
edit: spelling + more info
