I have never cycled my adaptogens. I've been taking ashwagandha and rhodiola for years as a daily.
That doesn't mean you should, man. A personal choice is a personal choice but when a personal choice is not the best one it's not wise to recommend for others to partake.
And I think you know me well enough to understand I'm not calling you out.
OP, let's take a little metaphorical walk lol.
Adaptogens such as Rhodiola and Ash are serotonergic, which means they increase serotonin. In fact, their adaptogenic properties are largely due to this MOA. Rhodiola also interacts with GABA receptors etc. This is important to know because elevated levels of serotonin or anything for that matter will cause down regulation of other important neurotransmitters, hormones, vitamins, hell, even fats.
Staying on topic with Rhodiola and Ash specifically. Dopamine and serotonin are antagonistic, meaning that if you have a constant rise in serotonin you will effectively lower dopamine. Dopamine is important for all sorts of roles in the body, one very important one being stimulating LH release, which stimulates the interstitial cells to make testosterone.
If you take something continually without cycling it, you never give your body a chance to restore homeostasis, which can cause a cascade of effects you don't necessarily want. The body operates in a dynamic state trying to stay completely balanced and operating with as little variance as possible. Everything in the body interacts with another part, hormone, neurotransmitter etc, which is why you should cycle EVERYTHING multivitamins, fish oils, supplements, so on and so forth
Moral of the story, everything should be cycled, everything, including foods
