Sleep and NMN

Hey Dr.H Curious to understand dosage timings for NMN, Alpha GPC and NR. For example, taking Alpha GPC, NMN, Rhodolia 5x/week in the AM (0600) works great for focus at the gym. I am cautious to take additional in the afternoon in case it keeps me up at night . Has there been any evidence to suggest this is true? Thanks

Low solar angle in the summertime for people who live way North

Hi Andrew. I’ve heard you talk multiple times about procedures for how to deal with sunlight in the wintertime when you live north (I live in Denmark) and how important sunlight timing is for sleep. However what about summertime when the sun rises at 3-4am and doesn’t set until 11pm? What’s the procedure in regards to sleeping schedule? I assume it wouldn’t make much sense going to bed 1130pm or midnight and waking up at 4am for the entire summer period due to insufficient sleep. I guess my question comes down to what constitutes low solar angle? If the sun rises at 4am is it still low at say 8-9am that same day? How do us northerners deal with the summertime sunlight? Kind regards Nicolai

Taking paracetamol daily

I might've overrheard or just simply misunderstood some info about taking paracetamol, ibuprofen or any other type of these pharmaceuticals and dosing them to half a pill a day. No idea which guest of yours said this info but I'm pretty sure I've heard this. So what's your opinion on taking half a pill of these drugs every day, even though I'm not in any sort of pain. Just simply for building immunity or taking it as a supplement. Might seem silly this question but I'm genuinely curious. Thank you.
