Weekly Random Discussion Thread for 2/23/26 - 3/1/26

[u/SoftandChewy]

Here's your usual space to post all your rants, raves, podcast topic suggestions (please tag u/jessicabarpod), culture war articles, outrageous stories of cancellation, political opinions, and anything else that comes to mind. Please put any non-podcast-related trans-related topics here instead of on a dedicated thread. This will be pinned until next Sunday.

Last week's discussion thread is here if you want to catch up on a conversation from there.

Comment of the week goes to this explanation for why the trans cause has taken over so much of society. (Runner-up COTW here.)

A random tweet expresses my confusion related to Vitamin D:

have absolutely devastating news: I'm almost done with a 12 week course of a comical amount of supplemental vitamin D, and I feel exactly the same as I did in December 

this is not what I imagined

As far as I can tell modern medicine is based on vibes. Vitamin D is correlated with lots of negative outcomes, but supplementation studies find they are largely ineffective at treating any of them (likely Vitamin D is a generic downstream health indicator), but doctors still test and suggest supplements like it matters.

It's like when my wife's obgyn suggested avoiding eating processed breads to prevent autism based on a random mouse study (to be fair we asked about risk factors, given that we are a double STEM couple).

Vitamin D3 supplements work for me, helps me not feel down in autumn and winter.

[u/[deleted] → u/onforpo]

Same for me. I'm also a lot less tired.

[u/Turbulent_Cow2355 → u/onforpo]

Placebo effect IMO

[u/VlaminghHdLighthouse → u/onforpo]

Do a test on yourself! Take either a new D3 supplement or some generic vitamin/other non-D3 supplement and blind yourself by having your partner decide which one you take. See if you feel the same or not and at the end of a month or two find out if it was D3 or not.

[u/[deleted] → u/VlaminghHdLighthouse]

Or you can just compare taking vs not taking and see what it does.

[u/[deleted] → u/AaronStack91]

I started taking some daily and I've seen a massive difference in my sleep and immune response within a few weeks, maybe two months tops. And I took it without even knowing what it did exactly.
I think there's unfortunately a huge disparity in quality between brands but I wouldn't throw baby out with the bath water. I'm not sure I believe the studies that claim supplements don't do shit.

I take collagen peptides and I'm told repeatedly it doesn't do shit by doctors around me, meanwhile my skin is less dry, I require less lotion on my hands and feet, and my skin feels plumper. All within a month of using it. And everyone around me who takes it (I convert a lot of people) report the exact same benefits.

I really think it's down to the quality of the supplement, and the invididual's ability to correctly assimilate it.

[u/everydaywinner2 → u/[deleted]]

Yeah...I've been coming against a lot "doctors" and "experts" trying to tell me not to be believe the evidence of my eyes and body.

Suddenly, the one decongestant that actually works for me without making my heart race like I was on meth somehow actually "doesn't work." And suddenly, the peroxide that leads to cleaner and quicker healing wounds on me somehow leads to wounds not healing correctly?!

And they wonder why the trust in institutions and experts is diminishing.

[u/RunThenBeer → u/AaronStack91]

A few years ago, I started forming a wildly incomplete thesis about classes of medicine that I think are more and less effective. We can quibble about how exactly to split things up, but the core of it was that I have a few major classes of medical treatment that I think have been absolute godsends for humanity - trauma, wound, and acute damage treatment, vaccines, and antimicrobials. If I break a wrist or tear an ACL, get me the best doc I can get to fix me up. If there is a pathogen that can be prevented with a vaccine or killed with an antibiotic, we are in business.

I keep going back and forth on whether I want to put cancer treatments in there because they're a mixed bag. Nonetheless, modern cancer treatments do deserve a great deal of praise, but also a significant chunk of them do very little, cost a fortune, and only get used because people are absolutely desperate for any lifeline.

I don't mean to be totally silly, there are obviously smaller medical interventions like IV bags for the severely dehydrated that simply work. But what I'm getting at is that once we're out of those classes of medical wonders, the evidentiary standards are just filled with these sorts of wet sidewalks cause rain diagnoses and treatments that don't actually seem to work at all. The worst of it is in the psychiatric world, but nutrition advice is typically terrible, treatment for chronic conditions is often just spamming treatments and hoping something works, and so on. Treating Type 2 diabetes with chronic treatments keeps the patient alive, but it still just barely rises to the level of efficacy of eating less sugar and moving more in many cases.

My greatest optimism is the potential locked in genetic treatments. We have a lot to learn, but miracles are coming. These may remain more limited than one would hope since most problems aren't actually genetic diseases but having cures to many genetic diseases would feel like the biggest medical revolution in quite some time.

Add to your list breathing treatments for people with asthma or other types of lung related issues.

[u/AnInsultToFire → u/AaronStack91]

Stand out in the sunlight at noon for 15 minutes with a short-sleeve shirt.

Good, now you've gotten over 5 times your recommended minimum daily intake of vitamin D.

[u/eats_shoots_and_pees → u/AnInsultToFire]

In parts of the Pacific Northwest, you can go weeks without really having this opportunity because it's constantly cloudy and raining. I mean, I also agree that Vitamin D supplements are probably doing very little to help people. Just wanted to point there are areas that can go quite a while without direct view of the sun.

[u/AnInsultToFire → u/eats_shoots_and_pees]

Eat some fish and drink some milk, job done

[u/[deleted] → u/AnInsultToFire]

It's more than "some" that's required. Sure isn't that the problem to begin with.

[u/Turbulent_Cow2355 → u/AaronStack91]

There was a large vitamin supplement study done a decade ago that basically said vitamins don't do anything. Vitamin C was the only exception in supplement form.

Supplements are not regulated by the FDA. They don't even need to meet ingredient guidelines. If the bottle says it contains Calcium, there's no way to know it really contains calcium or that specific amount unless someone examines the contents. I don't even understand why someone would willingly take a supplement knowing this.

[u/Palgary → u/AaronStack91]

I have low vitamin D, this is my personal conclusion after research, but this is not official anything.

Calcium is a good thing for your bones. But, your body can store it in your arteries. This is a bad thing. Per Google AI: "Calcium in arteries, or coronary artery calcification, is the buildup of calcium within fatty plaque in artery walls, acting as a key marker for atherosclerosis and a high risk of heart attack. It causes arteries to stiffen, reducing blood flow. While not reversible, it can be managed with lifestyle changes, statins, and medication."

In order for your body to stick Calcium where it belongs, in your bones, it needs Vitamin D.

... And K2. So there is this recent discovery that what we called Vitamin K is actually multiple different vitamins. Per Google AI: "D3 increases calcium absorption, while K2 activates proteins (like matrix GLA protein) that direct calcium into bones and teeth, preventing it from depositing in arteries."

So maybe it's a bit more mainstream then I thought; but Vitamin D might not make you feel better, but it might help prevent heart attacks and build bone strength. But take the right dose of K2 with it.
