How Much Protein Do You Need Daily?

Protein is a vital macronutrient, essential for building and repairing tissues, supporting immune health, and maintaining muscle mass. But how much protein do you actually need each day? The answer depends on various factors, including age, activity level, and overall health. Let’s break it down. 

The General Recommendation 

The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight per day. For example: 

However, the RDA is the minimum amount to prevent deficiencies—not necessarily the optimal amount for health and performance. 

Recent evidence indicates that these requirements may be underestimated. Analyses suggest higher needs of 0.91 g/kg to 1.2 g/kg for healthy adults based on refined nitrogen balance studies (Elango et al., 2010). 

Active Individuals and Athletes 

If you’re physically active or an athlete, your protein needs increase to support muscle repair and growth. Research suggests that: 

For example, a 70 kg (154 lbs) athlete may require between 84-154 grams of protein daily, depending on the type and intensity of exercise. 

Additionally, increasing protein intake can enhance lean body mass and strength, particularly in those engaging in resistance exercise, with optimal intakes of 1.2–1.6 g/kg for different age groups (Nunes et al., 2022). 

Protein Needs for Older Adults 

As we age, maintaining muscle mass becomes crucial to prevent sarcopenia (age-related muscle loss). Older adults often require 1.0-1.2 grams per kilogram to preserve muscle mass and overall physical function. For those with chronic illnesses, higher intakes of 1.2-1.5 grams per kilogram may be recommended (Bauer et al., 2013). 

Protein intake above 1.2 g/kg/day is associated with higher muscle, bone, and fat mass in elderly women, highlighting its role in reducing the risk of frailty (Genaro et al., 2015). 

Special Considerations for Women 

Women, particularly during pregnancy, lactation, or menopause, may have different protein requirements. For example: 

Protein and Weight Management 

Higher protein intake can also support weight management by promoting satiety and preserving lean muscle during weight loss. A daily protein intake of 1.2-1.6 grams per kilogram may help regulate appetite and improve body composition. 

How to Meet Your Protein Needs 

To meet your protein requirements, include a variety of high-quality protein sources in your diet, such as: 

A Practical Approach 

For most adults, aiming for 15-30 grams of protein per meal and including protein-rich snacks can help you meet your daily needs. Filling in the gaps with Organika's Protein Collection can help meet the daily requirements for protein. Remember, spacing your protein intake throughout the day is beneficial for muscle synthesis and overall health

The Bottom Line 

Protein needs vary based on individual factors like age, activity level, and health status. While the general RDA is a helpful starting point, many people benefit from higher protein intakes to support muscle health, weight management, and overall well-being. Recent studies highlight that optimal protein intake ranges from 1.2–1.6 g/kg for active individuals and aging populations, ensuring improved health outcomes (Nunes et al., 2022). Listen to your body, assess your lifestyle, and consult with a healthcare professional to determine the right amount of protein for you.
