Frequently Asked Questions

How much protein do I need per day?

Most people benefit from roughly 1.2 to 2.2 grams of protein per kilogram of body weight per day, depending on activity level and goal.

Can too much protein be harmful?

For most healthy adults, higher protein intakes within normal dietary ranges are not harmful, though anyone with kidney conditions should consult a doctor.

Is more protein always better for muscle gain?

No. Protein needs plateau once daily targets are met; extra beyond roughly 2.2 g/kg generally does not add further muscle-building benefit.
