Quick answer

Most adults need 0.8 to 2.2 grams of protein per kilogram of body weight daily, depending on activity level and goals. Athletes and those building muscle generally aim for the higher end.

Why protein needs vary

Your daily protein requirement isn't a one-size-fits-all number. Factors like age, muscle mass, physical activity, and overall health all influence how much protein your body actually uses. Sedentary individuals need less, while athletes or those recovering from injury need significantly more.

The role of convenience in meeting your target

Hitting a higher protein target can feel like a chore, especially with a busy schedule. Ready-to-drink shakes offer a quick, portion-controlled way to add protein without cooking or measuring. They're especially useful post-workout or as a snack between meals.

Frequently asked questions about daily protein intake

How much protein do I need per day for general health?

The Recommended Dietary Allowance (RDA) is 0.8 grams per kilogram of body weight. For a 150-pound (68 kg) person, that's about 55 grams daily. This is the minimum to prevent deficiency, not an optimal target for active individuals. Use 0.8 g/kg as your baseline, not your goal if you exercise.

How much protein do athletes need?

Athletes and those training regularly often need 1.2 to 2.2 grams per kilogram. Endurance athletes are on the lower end (1.2–1.6 g/kg), while strength athletes may need up to 2.2 g/kg to support muscle repair and growth. Adjust your intake based on training intensity, not just body weight.

Can I get enough protein from food alone?

Yes, but it requires planning. Whole food sources like chicken, eggs, dairy, legumes, and tofu can meet your needs. However, for convenience or when appetite is low, a ready-to-drink shake like the Optimum Nutrition Gold Standard Protein Shake can help fill the gap without extra effort. Whole foods first; supplements are a backup for busy days.
