Summary
The episode focused first on the Trump administration’s warning against Tylenol use in pregnancy and the claim that acetaminophen may be linked to autism. The guest said there are studies showing a correlation, but stressed that correlation is not causation and that the strongest evidence comes from sibling analyses, which have not found increased risk. She also noted that the relevant studies generally examine frequent use, defined as more than 28 days during pregnancy, not short-term use for a fever.
The guest argued the market impact on Kenvue and other acetaminophen makers should be limited because pregnant women are only a small slice of demand. She said Kenvue’s Tylenol business is only a high-single-digit portion of sales overall, and that media attention around drug safety usually causes a temporary stock move rather than a lasting shift.
The second half turned to TikTok’s US future and what an investor would actually be buying. The guest said the main assets are $1.6 billion in year-to-date in-app revenue, strong ad value, and highly engaged users who spend 80 minutes per day on the app in the US. She said ByteDance may license the algorithm to US owners, but any meaningful change to recommendations could hurt engagement and ad demand, with Instagram Reels likely a beneficiary if users migrate.
Key takeaways
- The guest said the best Tylenol studies use sibling comparisons, and those studies did not show increased autism or ADHD risk.
- She said the warning is aimed at frequent Tylenol use, meaning more than 28 days during pregnancy, not short-term fever treatment.
- Kenvue’s Tylenol exposure is limited because the brand is only a high-single-digit portion of sales, in her view.
- The guest said TikTok US is attractive for its $1.6 billion in year-to-date in-app revenue and heavy ad engagement, not just for the app itself.
- She said Instagram Reels is the most likely beneficiary if TikTok’s algorithm or user experience changes materially.

I don't know, Scarlet, I've said this before on Eric, Tylenol for my entire life has been the magic drug that fixes everything for me.
I know I have a mother who uh suffers from migraines and she would reach for the Tylenol all the time. So, what President Trump is saying is certainly uh eyepopping, I think, for a lot of people. — Yeah, exactly. Uh it's move in the stock as Charlie was just reporting. We want to get the latest uh from Bloomberg Intelligence and Hunter Van Kirk joins us. She covers the healthcare stuff for Bloomberg Intelligence. And what is the what's the science behind all of this? Is there science behind all of this or is this just President Trump and Mr. Secretary Kennedy kind of going off the the range a little bit?
Uh that's a that's a loaded question. Uh there are a lot of studies on it. Um it's certainly driven by an increase in finding a solution for the increased rates of ADHD and autism.
I think it's really important here to qualify um or quantify what we're talking about with frequent Tylenol use. And most of the studies are looking at um measured as more than 28 days over the course of your pregnancy. So that is a lot of Tylenol use.
We're not talking about you have a high fever and you take it for a day or two. Um this is this is kind of more long-term use.
