Justin Miller asked Timothy Ferriss:

Are there any pills/drugs/supplements that you never cycle off of? For example, I haven't cycled off of fish oil in about 2 years. Would you recommend I cycle off it?

Timothy Ferriss I cycle off of all supplements (or a given supplement) every 4-8 weeks, typically. It's hard to know all of the negative-feedback loops in the a biological system as complex as the human body, so better safe than sorry, IMHO.
