Proteins are essential macromolecules found in all living organisms and human cells. They are composed of long chains of amino acids and organic compounds derived from carbon, hydrogen, nitrogen, oxygen, and sometimes sulfur.

Proteins are essential for tissue building, repair, immune function, enzyme function, hormone production, and daily health maintenance, making their intake crucial for daily functioning.

Why Should You Take Protein?

Protein is a crucial component of our diet, playing a vital role in preserving and building muscles, repairing and developing muscle tissue, and maintaining good health, making it essential to consume enough for optimal health.You should know about the detailed benefits of protein that are given below.

Amazing Benefits of Protein

  • Muscle Growth and Repair: Protein is crucial for muscle building and repair, especially during resistance exercises involving micro-tears in muscle fibers, and provides amino acids for muscle growth and adaptation over time.
  • Maintaining Muscle Mass: As we age, we lose lean body mass, known as sarcopenia, and a higher protein intake is linked to preserving muscle mass, promoting mobility, and reducing frailty and fall risks in older individuals.
  • Weight Management: Protein-rich foods like chocolate protein bars are satiating and reduce appetite, aiding in weight management by maintaining a sense of fullness and reducing total caloric intake, as they are typically consumed with each meal and snack.
  • Immune Function: Antibodies are proteins in the immune system that recognize and disable foreign entities like bacteria and viruses, ensuring immune protection and promoting health.
  • Healthy Hair, Skin, and Nails: Proteins like collagen, keratin, pure protein bars, and elastin are essential for hair, skin, and nail growth and maintenance, providing health and beauty to these tissues.
  • Energy Source: Despite carbohydrates and fats being the primary energy sources, protein can be converted into amino acids and glucose through gluconeogenesis during exercise or fasting.
  • Transportation and Storage: Proteins transport molecules in an organism, such as hemoglobin in red blood cells, which transports oxygen from the lungs into tissues, and other proteins transport nutrients across cell membranes or store essential molecules like iron.
  • Hormone Production: Hormones, or peptides derived from proteins like insulin, glucagon, and growth hormone, control physiological processes like metabolism, growth, and reproduction.

How Much Protein Should You Eat Per Day?

Protein intake varies based on age, sex, body weight, activity level, and health goals, with general guidelines for daily intake. A nutritionist can provide personalized advice, ensuring the ideal protein intake based on your specific circumstances and a tailored approach to your health needs.

The recommended daily protein intake is 0.8 grams per kilogram of body weight, equivalent to 0.36 grams per pound, which is sufficient to meet nutritional requirements and prevent deficiencies.

Different Sources of Protein

  • Animal Sources: High-quality animal sources, such as chicken, eggs, beef, and pork, are rich in essential amino acids and provide protein, iron, and B-complex vitamins, making them ideal for obtaining essential amino acids.
  • Plant-based: Plant-based proteins like beans, legumes, and soy are essential for a healthy diet, providing protein, fiber, and nutrients with minimal fat and cholesterol.
  • Protein Supplements: Protein supplements like whey and protein bars with collagen are available for athletes and those seeking to increase macronutrient intake, easily adding to smoothies, shakes, or baked goods to meet daily protein goals.

What is The Best Time To Take Protein?

  • Pre-Workout: Consuming protein before exercise boosts muscle amino acid intake, aids in protein synthesis, and reduces muscle breakdown, especially during high-intensity exercises. It is recommended to consume a protein-rich snack or meal 1-2 hours before exercise.
  • Post-Workout: Protein is crucial for muscle recovery and growth post-exercise and can be consumed between 30 minutes and 2 hours post-exercise for building muscle mass or experiencing muscle breakdown from regular exercise.
  • Before Bed: Consuming a protein-rich snack or beverage before bedtime can help muscles recover and grow during sleep, especially casein protein, found in milk-based foods like cottage cheese or casein protein powder, due to its slow digestion rate.
    Daily Meals: Maintaining a consistent daily amino acid intake is vital for muscle protein synthesis, immune function, and overall health, promoting satiety and energy through a balanced diet.


Adults require 0.8 grams of protein daily for basic nutrition, while physically active individuals or athletes should consume 1.2 to 2.2 grams per kilogram of body weight, incorporating both animal and plant-based sources. Protein intake is crucial for muscle mass, immune function, and overall health; consult a healthcare professional to determine the appropriate intake for individual needs.
