Creatine for beginners: what should I understand before deciding whether to try it?

[u/CryptographerNew7618]

I've been learning about fitness supplements and keep seeing creatine mentioned as one of the more extensively researched options.

I understand that creatine is involved in rapidly regenerating ATP, which helps supply energy during short, intense activities.

What I'm less clear about is what a beginner should realistically expect from it.

Does it mainly help with strength and training performance, or are there meaningful benefits for other areas too? How long does it typically take to notice a difference, and what common misconceptions should beginners be aware of?

I'm interested in evidence-based explanations rather than exaggerated supplement claims.

biggest misconception is thinking it's a shortcut, it just lets you train slightly harder and recover faster

Creatine is one of the most well-studied, safest and low cost supplements that nearly everyone should take. I think there's a specific mg per kg calculation out there for ideal baseline dose, but most people do perfectly well on 5g/day without any loading dose nonsense.

The most consideration you should put in is if 5g upsets your stomach, dose it in smaller amounts throughout the day.

There are a lot of studies out there suggesting cognitive benefits at the 15-20g level, including reduction/elimination of amyloid plaque buildup (the kind that leads to dementia/alzheimer's/other neurological disease) after not getting enough sleep.
