What Are Protein Supplements?

Protein supplements are products designed to provide a concentrated source of high-quality protein.. They come in various forms, like powders, barras, ready-to-drink shakes and capsules. Its main objective is to help meet daily protein needs when it is not possible to do so through diet alone..

Why Are Proteins Important??

Proteins are essential macronutrients made up of amino acids, that perform multiple critical functions in the body:

  • Building and repairing muscle tissues.
  • Production of enzymes and hormones.
  • Strengthening the immune system.
  • Maintaining skin health, hair and nails.

Who Needs Protein Supplements?

Although we all need protein, Not all people require supplementation. Next, We present some groups that can benefit:

1. Athletes and People Who Train Regularly

  • Aim: Increase muscle mass, improve recovery and optimize performance.
  • Because: Intense training causes microdamage to the muscle that needs to be repaired with proteins.

2. People Looking to Lose Weight

  • Aim: Preserve muscle mass while reducing body fat.
  • Because: Proteins increase the feeling of satiety and keep the metabolism active during a low-calorie diet.

3. Older adults

  • Aim: Prevent age-related muscle loss (sarcopenia).
  • Because: As we get older, our protein needs increase to preserve strength and mobility.

4. Vegetarians and Vegans

  • Aim: Supplement a diet that may be low in complete proteins.
  • Because: Plant sources often lack some essential amino acids, and supplements can help balance intake.

Types of Protein Supplements

Not all proteins are the same. Depending on your needs, dietary preferences and goals, some types of supplements will be more suitable than others.

1. Whey Protein (Whey Protein)

The whey protein It is the most popular supplement and one of the most studied. It is obtained from whey, the liquid left after cheese making.

  • Advantages:

    • High bioavailability (absorbs quickly).
    • Rich in essential amino acids and leucine, key to muscle synthesis.
    • Ideal for post-workout consumption.
  • Types of Whey Protein:

    • Concentrated: Contains between 70-80% of protein and a small amount of carbohydrates and fats.
    • Isolated: Contains more than 90% of protein, with less lactose and fat.
    • Hydrolyzed: Pre-digested for faster absorption and lower risk of allergies.

2. Casein Protein

Casein is also derived from milk, but it is digested much more slowly than whey.

  • Advantages:
    • Sustained release of amino acids during 6-8 hours.
    • Ideal to take before bed to prevent nocturnal catabolism.

3. Vegetable Proteins

Perfect for vegetarians, vegans or people with lactose intolerance.

  • Types of Vegetable Proteins:

    • Pea Protein: Rich in essential amino acids and highly digestible.
    • Brown Rice Protein: Complete source when combined with other plant proteins.
    • Soy Protein: Considered a complete protein, comparable in quality to those of animal origin.
  • Advantages:

    • Suitable for plant-based diets.
    • Low in allergens such as lactose or gluten.

4. Egg Protein

Egg protein is another high-quality option.

  • Advantages:
    • High bioavailability.
    • Gluten lactosa.
    • Contains all essential amino acids.

When to Take Protein Supplements?

When you consume protein can influence the benefits you get. Here we explain the best times to take supplements:

1. After Training (Post-Workout)

  • Because: During this “anabolic window,” muscles are more receptive to amino acids.
  • Benefit: Speeds recovery and maximizes muscle protein synthesis.

2. Before Sleep

  • Because: Overnight, the body enters a fasting state.
  • Benefit: Consuming casein before bed prevents catabolism and promotes nocturnal muscle repair.

3. Breakfast or Between Meals

  • Because: Some people have difficulty meeting their daily protein requirements from food alone.
  • Benefit: Supplementing between meals keeps the body in a constant anabolic state.
