Frequently Asked Questions

How much protein do I really need?
Protein needs vary based on factors like weight, activity level, and goals. The general RDA is 0.8g per kg of body weight, but active individuals may need 1.2-2.2g per kg. Our calculator personalizes this for you.
Can I consume too much protein?
While rare in healthy individuals, excessive protein (over 3g/kg long-term) may strain kidneys. Our calculator shows a safe range. Consult a doctor if you have kidney issues.
Is plant protein as good as animal protein?
Plant proteins can be just as effective when properly combined (like rice + beans). Our calculator adjusts for diet type to ensure you get complete protein.
When is the best time to consume protein?
Spread intake evenly throughout the day. Post-workout (within 2 hours) is especially important for muscle recovery. A protein-rich breakfast can help control appetite.
Do I need protein supplements?
Most people can meet needs through food. Supplements can help if you struggle to consume enough protein or need convenience post-workout.
How does age affect protein needs?
Older adults may need more protein (1.0-1.2g/kg) to combat age-related muscle loss. Our calculator accounts for this in the recommendations.
