What's the deal with melatonin doses? 0.3 vs 3 vs 10 mg?
I've been reading a lot about melatonin for sleep support, especially since I'm ramping up my training for a marathon. Some sources say lower doses like 0.3 mg are effective, while others recommend the standard 3 mg or even up to 10 mg. I'm skeptical about just throwing a bunch in my system without understanding the science behind it. What have you all experienced? Does higher mean better, or is there a sweet spot that actually works? I'm trying to find the most effective dose without messing with my sleep cycle or feeling groggy the next day.
