Frequently asked questions

How much protein do I really need?

Active people often do well at 1.6 to 2.2 g per kg. Sedentary needs are lower; this tool sets the range from your goal.

Can I eat too much protein?

For healthy people, high protein is generally safe. Those with kidney conditions should consult a doctor.

Does timing matter?

Total daily intake matters most; spreading protein across meals (20 to 40 g each) is a reasonable practice.
