How Much Protein Do You Really Need?

Protein often gets the spotlight when it comes to nutrition—and for good reason! It’s essential for building and repairing tissues, supporting muscle strength, maintaining healthy hair, skin, and nails, and keeping you feeling full and satisfied. But how much protein do you actually need each day—and can you have too much?

How Much Protein Do You Need? 

• The ideal amount of protein depends on your age, activity level, and goals. 
• For most healthy adults, the general guideline is 0.8–1.2 grams of protein per kilogram of body weight per day. 
• If you’re active, trying to build muscle, or working on body recomposition, you may benefit from 1.2–2 grams per kilogram. 
• Older adults or those recovering from illness may also need a bit more to help preserve lean body mass.

For example, someone weighing 150 pounds (about 68 kg) might aim for 80–100 grams of protein per day spread across meals and snacks.

Best Sources of Protein

You can meet your protein goals through a mix of animal and plant-based options, such as: 

• Lean meats, fish, poultry, eggs 
• Greek yogurt or cottage cheese 
• Beans, lentils, quinoa, and soy products 
• Nuts and seeds

Can You Have Too Much Protein?

While protein is important, more isn’t always better. Consistently eating very high amounts (especially from supplements rather than food) can strain your kidneys and liver in those with pre-existing health conditions. Excess protein may also crowd out other vital nutrients like fiber and antioxidants.

The key is balance—aim for steady protein intake throughout the day, paired with colorful vegetables, whole grains, and healthy fats to support overall wellness.

The Bottom Line

Protein is a powerful ally in your health and metabolic goals, but it’s not a solo act. Finding the right amount for your body helps you build strength, stabilize energy, and feel your best—without overdoing it.
