Key Takeaways
- ✓Creatine brain dosing: The body's muscles absorb most of the first 5 grams of daily creatine, leaving little for the brain. Supplementing at 10 grams daily causes measurable creatine increases across multiple brain regions, per a German study. Those under cognitive stress, jet lag, or sleep deprivation benefit most from this higher threshold.
- ✓Sleep deprivation offset: A dose of 25–30 grams of creatine given to subjects sleep-deprived for 21 hours fully negated their cognitive deficits in studies by Dr. Darren Candow at the University of Regina. Cognitive performance actually exceeded that of well-rested, unsupplemented individuals, making high-dose creatine a practical tool for unavoidable sleep-deprived high-performance situations.
- ✓Hair loss myth debunked: A single 2009 study on rugby players given 25 grams daily showed elevated DHT levels but never measured actual hair loss and has never been replicated. A 2025 randomized controlled trial with 45 resistance-trained men taking 5 grams daily for 12 weeks found no significant difference in hair outcomes versus placebo.
- ✓Depression and creatine combined therapy: A 2025 study found that patients receiving creatine supplementation alongside cognitive behavioral therapy showed greater reduction in depressive symptoms than those receiving CBT alone. Creatine appears to reduce brain stress through both energy regeneration and a newly identified anti-inflammatory mechanism, though the exact pathway remains under active research.
- ✓Fasting window for metabolic benefit: Compressing eating into a 6-hour window and fasting for 18 hours produces measurable improvements in glucose regulation and blood pressure beyond what caloric restriction alone achieves. Studies comparing equal-calorie groups show the fasting group consistently outperforms on these metabolic markers. Autophagy activation typically begins after 12–16 hours of fasting once liver glycogen depletes.
What It Covers
Rhonda Patrick explains creatine's dual role in muscle performance and brain function, covering optimal dosing strategies from 5 to 25 grams, cognitive benefits under sleep deprivation and stress, cancer risk associations, and how fasting triggers autophagy for cellular repair and metabolic improvement.

Notable Moment
Rhonda Patrick reveals that a 2025 observational study of 25,000 people linked each incremental rise in creatinine levels to a 14 percent reduction in cancer risk — directly contradicting a widespread public fear that creatine supplementation might promote cancer development.
Episode Transcript
The thing I think about most, especially when I'm on the go, but also when I'm sat here in the Diary of a CEO studio, is the WiFi and Internet that we have to work with. In fact, anytime I'm filming away from the studio, one of the first things I do is when I arrive, I open up an app and do a speed test to see how strong the signal is. And the number of screenshots I've sent to my team about WiFi signals at different locations is actually pretty crazy. It matters that much to me because it's such a competitive advantage to have fast WiFi. Because on any given day, if I'm recording, let's say, hours and hours of footage with a podcast guest, I then often have to have my team send that across to our London team who then do the edit. So fast WiFi and Internet is not nice to have. It is absolutely business mission critical. So when it came to finding the best provider who could supply Internet and WiFi to our new LA studio, which I'm certain right now, we looked at every single option. And of all the providers, the one that came back with the steadiest connection, as well as being the cheapest, was today's sponsor, Spectrum Business. Spectrum Business keeps businesses of all sizes connected with fast, reliable Internet, advanced Wi Fi, phone, TV, and mobile services. Millions of business owners already rely on Spectrum to keep their operations connected. So if you wanna join them, head to spectrum.com/business to learn more. That's spectrum.com/business. Restrictions apply. Service not available in all areas. When I asked you before this conversation started rolling, what you're really excited about at the moment, your response to me was there was a few things, but one of them, which lit up your face, was creatine. Yes. And it's funny because It lit up your face again. Yeah. It's it's funny because creatine has been around for, I mean, ever, for decades. And it's always been in my mind, it was, like, one of those gym bro things. I'm like, I don't need to be swole. Yeah. Yeah. I don't need creatine to get get swole. And, you know, this is this was the thought for for many, many years. And then over the last five years or so, the effects of creatine on the brain started to really get my interest. Anything that affects the brain, I really become interested in. And so that's kind of what did get me the most excited about about creatine. But also I started doing a lot of resistance training, and so I was like, okay, here I am now. I'm like one of those gym guys. I'm doing I'm doing the barbells. I'm doing the, you know, the squats and the deadlifts and all that, and so so why not give myself some of the creatine? Well, what is creatine? Right? Why is it important? …
