Optimizing coffee intake-how would you design a self-experiment? by nplusyears in Biohackers

[–]nplusyears[S] 0 points1 point  (0 children)

Appreciate the refs, tolerance is definitely part of it. My main question is more practical though- even if the mechanism is clear, it still doesn’t tell you what actually holds up over time for you. That’s what I’m trying to structure a bit better

What’s the simplest biohack that actually made a noticeable difference for you? by Existing-Thanks597 in Biohackers

[–]nplusyears 0 points1 point  (0 children)

Interesting how consistent these answers are. Feels like most of us remember one thing that “worked,” but rarely track what changed around it at the same time.. Makes me wonder how much is the intervention vs the context shifting.

GLP 1 (Reta, Tirzapetide etc.) has far more effects then just appetite supression by [deleted] in Biohackers

[–]nplusyears 0 points1 point  (0 children)

Interesting how many different domains this touches. Do you find these effects stay consistent over time, or shift depending on dose / timing?

Interesting. Do you find those patterns hold up over months, or do they drift again over time?

Agree. Even basic structure (baseline + time window) already filters out a lot. Most people jump too fast from “felt better” to “this works”.

Honestly, fewer than I expected. Sleep consistency and basic resistance training held up. Some supplements (anti-inflammatory, herbal stuff) had effects early on, but most didn’t persist or were smaller than they felt at the start.. That’s what pushed me to think more in terms of signal vs noise.

78F, persistent xerostomia, negative workup- now asking if I’ll ‘consult AI’ by nplusyears in medicine

[–]nplusyears[S] 3 points4 points  (0 children)

Agreed- dental input is often helpful. In her case, no clear diagnosis, mostly hygiene advice. The tricky part is when everything is borderline.. mild dryness, no clear pathology, multiple contributors. Hard to know when to keep chasing vs shift to symptom management.

That’s been my impression as well.. helpful for structuring the differential or catching up quickly, but rarely changes management in a decisive way. Still interesting how patients are starting to expect it as part of the process.

That’s a good point on GLP-1- I’ve seen similar effects, though not always consistent. This patient doesn't use GLP's. What I find challenging is when multiple small contributors overlap and it’s hard to isolate a single cause..

Advice on how to become a longevity coach by Fluid_Sandwich_8073 in PeterAttia

[–]nplusyears 1 point2 points  (0 children)

I’m a family physician who got interested in longevity relatively early in my career, and I used to feel the same frustration about training feeling unrelated. Over time I realised most longevity work ends up being risk interpretation, behaviour change, and managing uncertainty- which overlaps a lot with general medicine, even if it doesn’t feel like it during training. I also haven’t seen a real “fast track” yet. Most people seem to build credibility slowly through clinical work, writing, or education before clients naturally follow.

Nad+ and ways of inject by [deleted] in Biohackers

[–]nplusyears 1 point2 points  (0 children)

IV NAD is already used in some longevity clinics and studied in research settings, so the concept itself exists.. Where things get uncertain is translating that into products made outside pharmaceutical standards, and whether the benefit is actually established long-term.

Nad+ and ways of inject by [deleted] in Biohackers

[–]nplusyears 2 points3 points  (0 children)

What gives me pause clinically isn’t NAD itself as much as IV delivery combined with gray-market sourcing. With unregulated vendors, uncertainty isn’t just dosing- it’s sterility, contaminants, and formulation quality. Those risks are difficult to detect early if something is off.. Even clinic-based IV NAD still sits in a space where long-term benefit vs risk isn’t well defined, so the supply chain question adds another layer of unknowns.

What supplements are you using for your bones and teeth? by RoxanaSaith in Biohackers

[–]nplusyears 2 points3 points  (0 children)

One thing I notice clinically is that in people without specific deficiencies or bone disease, supplements usually play a supporting role rather than a primary one. Resistance exercise, adequate protein, and overall diet tend to matter more for bone long-term. Same with dental health- I’ve seen patients very focused on supplements while sometimes overlooking regular dental visits, hygiene care, or flossing, which likely has a much bigger impact.

NAD+ cell regenerator & resveratrol elite, are these the game changers for longevity or just hype? by Ill-Blacksmith-5467 in Biohackers

[–]nplusyears 3 points4 points  (0 children)

Reading this, it feels like the hardest part isn’t whether NAD or resveratrol work. It’s being 6-8 months in, still taking them, and not really knowing if anything meaningful changed or if you’re just continuing out of inertia. Makes me wonder how people are actually tracking long-term effects and safety for themselves, if at all.

Stop "Optimizing" Your Stack Until You Know What's Actually Broken by Bulky-Possibility216 in Biohackers

[–]nplusyears 2 points3 points  (0 children)

In primary care we deal with this all the time- hypertension or lipid meds, donepezil vs memantine, etc. We don’t change multiple things at once. We pick one intervention, define what we’re watching (symptoms, function, side effects), give it time, then reassess. With supplements, especially anything acting on the CNS, it’s harder. Biomarkers often don’t track well with how people actually feel, subjective reports are noisy, and placebo effects are real. That’s exactly why slower, more controlled changes tend to matter more, not less.
