- Loading phases, timing, and the simplest way to take creatine
- Depression, brain injuries and emerging creatine research
- Why creatine won’t turn you into Mr Olympia, and why that’s good news

Ask yourself while you listen:
“Am I chasing supplements to avoid facing how I actually live?”

Timestamps:
- Creatine is basically stored potential energy in your muscles – and your brain can use it too. (01:43–02:10)
- If you’re asking, ‘Do I need creatine if I don’t exercise?’… my first question is, why don’t you exercise? (04:18–04:35)
- We think creatine really matters when the brain is under stress – sleep loss, low oxygen, mental fatigue, trauma, disease. (05:10–05:34)
- For 99.9% of kids, creatine isn’t necessary. I always ask, why are we giving supplements to children? (08:34–09:18)
- Creatine doesn’t damage your kidneys – but it can confuse your bloodwork if your doctor doesn’t understand creatine metabolism. (09:38–11:10)
- Some creatine gummies we tested had literally zero creatine in them. They were just candy. (13:25–14:15)
- We found no difference taking creatine before or after training. The best time is when you’ll actually take it. (24:15–26:20)
- Creatine might help preserve some of those fast-twitch fibres as you age, but you still need to move explosively. (32:07–33:13)
- If you’re sleep deprived, creatine can blunt the drop in brain performance – your passing accuracy stays almost the same. (34:31–35:30)
- People with depression tend to have lower brain creatine, and in several trials creatine plus meds worked better than meds alone. (37:54–39:15)
-The effect size of creatine is small. It’s not going to turn you into Mr Olympia.” (44:16–45:07)
