I'm not a doctor or a dietitian. I'm a 35-year-old desk worker who took zero supplements his whole life, then started boxing and got humbled. Now I'm trying things one at a time, on myself, and writing down what actually happens. This is my log, not advice.

Restarting — a week of stomach flu, 79 kg, and rethinking iron
One week of porridge and soup. No training, no supplements, weight down to 79 kg. Restarting today, and thinking about adding iron.
Where I've been for a week.
I've been sick. Bad stomach flu — the kind that keeps you close to home and empties the tank. For the past **seven days** it's been almost nothing but **porridge and soup**. That's the whole menu. Anything heavier and my stomach wasn't having it.
What I stopped.
Everything. **No boxing. No running. No lifting.** Not a single training session in a full week. And because I couldn't hold real food down consistently, I also **stopped the supplements** — creatine and the multivitamin both. Taking pills on an empty, angry stomach felt like a bad idea, and I'd rather pause cleanly than half-take things and muddy the log.
The weight.
**Down to 79 kg.** I was at 80 and trying to work my way toward 85. A week of porridge undid weeks of eating on purpose. Not surprising, but still frustrating to see on the scale.
The frustrating part.
The whole point of this log is a clean n=1 — one variable at a time, consistent doses, honest observation. A week-long break in the middle of the creatine + multivitamin run means **I lose a clean read** on what those two were actually doing. The pump, the recovery, the morning heaviness — I can't cleanly compare "week 3 on creatine" against "week 5 on creatine" now, because week 4 was a hole.
That's just how real life goes. You don't get to control for illness.
Restarting today.
Starting today I'm back on the stack:
- Creatine 5 g, daily.
- Multivitamin, one cap with a meal.
No loading phase, no doubling up. Just picking up where I left off and letting the levels come back over the next couple of weeks. I'll ease back into training too — probably a light run before I go back to full boxing rounds.
The new thing I'm thinking about — iron.
Here's what's been on my mind. Over the last little while, before and during the illness, I've been noticing what feels like **mild anemia symptoms** — a bit lightheaded standing up too fast, more fatigue than the training alone should explain, that generally washed-out feeling. Being sick and under-eating for a week almost certainly made it worse, so I can't fully separate the two.
But it's enough of a pattern that I want to think seriously about adding iron to the stack.
I'm not going to just start swallowing iron pills tomorrow. A few things I want to work through first:
- Iron isn't like a multivitamin — too much is genuinely harmful, and men in particular don't clear excess iron well.
- The right move is probably a blood test first. Ferritin, hemoglobin, the basics. Guessing on iron is a bad idea.
- If I do end up supplementing, dose and timing matter a lot — iron with vitamin C helps absorption, but iron next to calcium or coffee fights it.
So for now: iron is on the "next candidate" list, but it goes in after I get labs, not before.
Overall condition.
**Weak, but on the mend.** Stomach is finally cooperating. Appetite is coming back slowly. Energy is still low. Today's the reset — real food, restart the two supplements, no training yet, and start planning the iron question the right way instead of the fast way.
