00:00:00.000 Hey everyone, welcome to a sneak peek, ask me anything or AMA episode of the drive podcast.
00:00:15.820 I'm your host, Peter Atiyah. At the end of this short episode, I'll explain how you can access
00:00:20.280 the AMA episodes in full, along with a ton of other membership benefits we've created,
00:00:24.900 Or you can learn more now by going to peteratiyahmd.com forward slash subscribe.
00:00:30.600 So without further delay, here's today's sneak peek of the Ask Me Anything episode.
00:00:38.900 Welcome to Ask Me Anything AMA episode 85.
00:00:42.000 Today we're talking about medications and supplements.
00:00:44.360 This is one of the topics I get asked about more than almost anything else,
00:00:47.620 and I think it's also one of the easiest areas to go wrong.
00:00:51.000 People tend to ask me whether something is good or bad, whether they should take it or not,
00:00:54.600 but those are, I think, kind of the wrong questions. The right question is whether a
00:00:58.240 specific intervention makes sense for a specific person with a specific problem, and that's what
00:01:03.020 I'm going to try to get to today. So in this episode, we'll cover why defining the problem
00:01:07.340 matters more than picking the intervention, the different jobs a medication or supplement can do,
00:01:12.780 and why the evidence bar should move depending on the job, how to tell strong evidence from weak
00:01:18.180 evidence, and why mechanism alone isn't enough, why baseline risk changes everything, and how
00:01:24.140 relative risk can mislead you. How to think about the real downside of taking something,
00:01:30.120 side effects, yes, but also cost, hassle, and opportunity cost. How to determine whether the
00:01:36.120 supplement you're taking is having any real effect. How to stop taking something. Why supplements
00:01:42.540 specifically deserve a lot more skepticism than people give them. And finally, the short list of
00:01:49.080 over-the-counter supplements that I think are probably worth the risk-reward trade-off.
00:01:54.820 So without further delay, I hope you enjoy AMA number 85.
00:02:03.660 Peter, welcome to another AMA. How are you doing?
00:02:06.100 Very well, thanks.
00:02:07.080 Good. We will get right into it today on AMA All-Around Medications and Supplements. So
00:02:13.500 So first question, before someone takes any medication or supplement, how do you think that they should define what the problem is in a way that increases the odds that they look for and pick interventions that actually benefit them and reduce risk opposed to at best waste money and at worst cause other harm that they don't know about?
00:02:36.080 You know, I think this is actually one of the biggest challenges from a sort of mental model standpoint is plaguing most people when they think about supplements in particular, but I think also, frankly, pharmaceuticals.
00:02:47.740 So people are, I think, typically defining the problem at the wrong level of abstraction.
00:02:53.960 So they'll say things like, I want to be healthier or I want more energy or I want to pursue better longevity.
00:03:01.680 And the challenge is that those are not really actionable problem definitions. They're vague, difficult to measure, very difficult to falsify, and things like that. So I would suggest that we reframe this discussion around what would be actionable metrics or actionable parts, right?
00:03:19.500 So one would be a metric that can be studied. Two would be a threshold against which you would
00:03:25.000 measure. And then I think a third potential one would be a time horizon. So what am I measuring?
00:03:30.740 What level tells me that there's a problem and by extension, a solution? And when do I expect
00:03:38.100 that to happen? And so if you can't come up a priori with some sense of those things, you're
00:03:43.320 probably not in a good spot to start anything. So for example, let's use a tangible example.
00:03:49.680 Instead of saying my cholesterol is bad, you would say my ApoB is 130 milligrams per deciliter. I
00:03:55.740 want to get it below 60 milligrams per deciliter, and I'd like to do that in the next six months.
00:03:59.980 Instead of saying, you know, my sleep is bad, you might say it takes me 60 minutes to fall asleep
00:04:04.320 on, you know, four or five nights a week, and I want to make that under 10 minutes to fall asleep
00:04:11.560 within two months. So that's a real problem definition. The next question is the counterfactual.
00:04:18.280 What happens if I do nothing? Does this problem meaningfully increase risk, reduce quality of life,
00:04:23.820 or create some downstream consequence? So I think this question is important because it separates
00:04:29.060 real problems from things that merely feel actionable. And it matters because poor problem
00:04:35.540 definition almost guarantees some sort of false positive. So if the problem is vague, almost
00:04:40.500 anything can look like it helped. You sleep a little better one week, your energy is a little
00:04:45.200 better on Tuesday, one lab improves a little, and now you're telling yourself a story. And we all
00:04:50.880 do this. I mean, we're storytelling machines. And I think that's how people end up taking things for
00:04:56.100 years without ever knowing if they've solved anything real. So I think the rule here could
00:05:02.400 be pretty simple, right? Do not start with the molecule, start with the problem. Define tightly
00:05:07.940 enough that you could actually be proven wrong. So if you can't state the metric, the threshold
00:05:12.960 and the timeline, and even the consequences of doing nothing, you're not really making an
00:05:18.140 intervention decision. You're, you're probably impulse shopping on, you know, your favorite
00:05:21.900 website. And when looking at different medications and supplements, how do you think about and maybe
00:05:28.800 classify the quote unquote job that they would do? And based on that classification, does it
00:05:37.200 change the evidence threshold you like to see and how much risk you're willing to tolerate?
00:05:43.880 Well, once the problem is defined, I think the next question is asking, okay, what is the purpose
00:05:51.500 of that intervention? And again, it matters because it requires different standards. So
00:05:57.640 if you don't classify this job as you describe it correctly, you're very likely going to apply
00:06:03.180 the wrong evidence threshold and accept the wrong amount of risk. So I think we could put these into
00:06:08.920 four buckets, disease treatment, symptom relief, risk reduction, and I hate the term, but I think
00:06:17.780 we just need to use it and it's optimization. So they might sound sort of similar on the surface,
00:06:23.100 but they're actually quite, quite different. So if the, if the quote unquote job is disease
00:06:26.980 treatment, the bar is high, right? Does this improve the disease in a meaningful way? And of
00:06:33.380 course, here you would be willing to accept more downside because the underlying problem is serious
00:06:38.020 and the counterfactual is strong. Presumably, if you have a disease and you do nothing,
00:06:43.120 the disease will get significantly worse. But at the same time, you're going to want stronger
00:06:47.000 evidence, ideally hard outcome trials, or at least some well-validated surrogate endpoint,
00:06:52.520 not just a compelling story. Now, if the job is symptom relief, the question is a bit different.
00:06:58.180 Does the person actually feel or function better? And here we're dealing with something that's
00:07:04.080 subjective. You may be willing to frankly tolerate placebo risk because if the symptoms
00:07:09.820 meaningfully improve and the downside is low, that could still be a reasonable trade-off.
00:07:14.880 If the job is risk reduction, you're treating something that a person can't feel almost by
00:07:20.860 definition. So the evidence bar again here needs to be pretty high. That usually means hard outcomes
00:07:25.920 when available, or again, at least a very validated surrogate marker. And again, not all biomarkers
00:07:32.200 are equal here. ApoB is a very well-validated surrogate biomarker, whereas some vague
00:07:40.180 inflammatory marker or heavy metal is not necessarily going to be in that category as
00:07:46.740 someone's pontificating about detoxifications or something like that.
00:07:50.860 If the job is optimization, then I think skepticism should go up, right?
00:07:55.860 This is where error rates are highest.
00:07:57.900 The person is usually starting from a relatively healthy baseline, and the expected effect is often small.
00:08:03.920 The claims are usually made in a mechanistic way, and there's generally no objective way to determine whether the supplement or medication is benefiting you, making your ability to basically fool yourself enormous.
00:08:18.660 So I think the challenge and probably the reason we're even doing this episode is in part because most of the longevity interventions are really optimizations masquerading as risk reductions.
00:08:31.160 They kind of borrow the language of prevention, aging, healthspan, resilience, longevity, but the actual evidence that they put forth looks much more like speculative optimization interventions rather than true risk reduction.
00:08:43.500 And I think this distinction really matters, right? This classification should change both
00:08:47.840 your evidence threshold and your risk tolerance. I think the more serious and concrete the problem,
00:08:53.460 the more downside you may be willing to keep, as I said, and the more speculative the goal,
00:08:58.300 the less downside you should be willing to tolerate. So I guess to summarize that,
00:09:02.500 if you're looking at disease treatment, you want to demand strong evidence, but you'll accept more
00:09:06.220 risk. If you're looking at symptom relief, you prioritize the actual lived benefit, but watch
00:09:11.240 for placebo and noise and factor in the unknowns about safety. Risk reduction, you're going to
00:09:16.360 have to look at validated surrogates or hard outcomes, although the latter tends to be
00:09:19.900 challenging. And if it's about optimization, you're going to default into a skeptical state,
00:09:25.360 especially around safety. So Peter, let's double click on one of the things you briefly mentioned
00:09:31.020 there, which is kind of evidence when looking at medications and supplements. So when people
00:09:36.160 are evaluating how they're thinking about a medication and supplement for themselves,
00:09:39.940 what are common ways that you see people confuse the different tiers of evidence and how can people
00:09:47.880 prevent that in practice so how can people be a little bit more aware so when they're looking at
00:09:52.980 various claims they start to understand how good those claims are thank you for listening to today's
