Most Replayed Moment: Can Creatine Offset Sleep Deprivation? Is It Really The Best Supplement?

Before we hit record I asked what you’re most excited about right now, and you lit up about creatine—why?

I used to think creatine was just a gym-bro thing, but the brain benefits pulled me in as I got serious about lifting; our liver and brain make a little, yet muscles are greedy because creatine helps regenerate energy.

With resistance training it lets you squeeze out extra reps and recover faster between sets, so five grams a day meaningfully boosts strength and lean mass when you actually train.

The brain is energy-hungry too, and under stress—like poor sleep or heavy cognitive load—creatine seems to shine once muscles are topped up and more can reach the brain.

I take ten grams daily and go to twenty to twenty-five grams when I am jet-lagged or facing high-demand days, and I notice fewer afternoon dips even if placebo plays a part.

Vegans often feel a big lift because they get little through diet, with many reporting steadier energy and sometimes needing less sleep.

Do you need a loading phase, or could a morning dose sharpen thinking that same day?

Loading just speeds muscle saturation for studies, but for the brain you can get an acute effect when intake exceeds five grams because spillover reaches the brain, especially under stress.

I saw a 2025 study where adding creatine to cognitive behavioral therapy improved depressive symptoms more than therapy alone.

Depression is brain stress tied to inflammation and oxidative strain, and early data hint creatine may temper inflammation and bolster energy; a small uncontrolled Alzheimer’s pilot using twenty grams showed cognitive gains, but we need rigorous trials.

There was also a large cohort suggesting tiny increases in creatine intake correlated with lower cancer risk.

That link is intriguing and flips the old fear on its head, though mechanisms—possibly anti-inflammatory—are still unclear.

People worry about bloat and hair loss.

A 2025 randomized trial found no differences in dihydrotestosterone or hair with five grams over twelve weeks, unlike an old rugby study that only showed a DHT bump at very high doses.

That hair-loss scare came from a single unreplicated study, and real-world water weight from creatine is small and usually a nonissue.

Let’s switch to fasting—how should we approach it and who benefits?

Start with your goal, because for weight loss a calorie deficit does the heavy lifting and time-restricted eating mainly helps you eat less without counting.

Does a calorie deficit alone put you in ketosis?

Not necessarily, since fasting flips on pathways you do not trigger while fed, like autophagy that clears damaged cellular material, including plaques.

Mitochondria get cleaned up via mitophagy, and while human markers are limited, autophagy likely ramps after roughly twelve to sixteen hours once liver glycogen is depleted.

Beyond weight, fasting can improve glucose control and blood pressure, and tight windows—like six hours eating and eighteen hours fasting—often beat equal-calorie diets on those measures.

That was one of our most replayed moments from a past episode; the full conversation is linked in the description—thanks for listening.
