Common questions

Fitness supplements FAQ

Which fitness supplement should I start with?

Whey protein for recovery and creatine monohydrate for strength are the two best-researched starting points. Both have decades of evidence behind them.

Is creatine safe to take daily?

Yes. Creatine monohydrate is one of the most studied supplements in the world and is generally considered safe for healthy adults at recommended doses (3–5g daily).

Whey concentrate or whey isolate?

Isolate has more protein per scoop and less lactose, while concentrate is cheaper and slightly less processed. Both are excellent — pick based on your budget and digestion.

Do pre-workouts contain dangerous ingredients?

Most are fine at label doses, but check for transparent ingredient labels and avoid proprietary blends with undisclosed amounts. Caffeine-sensitive people should start with half a scoop.
