🔬 Why Is Protein Most Important?
Proteins are the main building material for muscles. After training, muscle fibers are damaged and need amino acids for recovery and growth. However, NOT all proteins are the same — different forms have different absorption rates, amino acid profiles and purposes.
📊 All Protein Forms — Comprehensive Comparison
| Form | Absorption Rate | Protein % | Lactose | Price | Best Use |
|---|---|---|---|---|---|
| Whey Concentrate (WPC) | Fast (1-2 hours) | 70-80% | Yes | Low | After Training |
| Whey Isolate (WPI) | Very fast (1 hour) | 90%+ | Minimal | Medium | Post-workout, lactose intolerance |
| Whey Hydrolysate (WPH) | Especially fast (30 min.) | 80-90% | Minimal | High | For professionals, competitions |
| Casein (Micellar) | Slow (6-8 hours) | 80-85% | Yes | Medium | Before sleep, between meals |
| Egg Protein | Medium (2-3 hours) | 80-85% | None | Medium-High | Lactose-free, high quality |
| Soy Protein | Intermediate | 80-90% | None | Low | For vegans, plant-based |
| Pea Protein | Intermediate | 80-85% | None | Medium | For vegans, those allergic to soy |
| Beef Protein | Medium-Slow | 90%+ | None | High | Lactose-free, paleo diet |
🎯 Which Form to Choose by Goal?
💪 For Muscle Growth
Whey concentrate (WPC) post-workout + casein before sleep. WPC quickly supplies amino acids for recovery, casein maintains a steady level throughout the night. Best price-quality ratio.
⚖️ For Weight Loss
Whey isolate (WPI) or casein. Both are low in carbohydrates and fat. Casein provides a feeling of satiety for longer — perfect as a snack replacement.
🌱 For Vegans
Pea + rice protein blend. Separately, they do not have a complete amino acid profile, but together they complement each other. Ideal leucine content for muscle protein synthesis.
🤧 For Allergy Sufferers / Sensitive Individuals
Egg protein or pea isolate. Lactose-free, soy-free, gluten-free. Egg protein has the highest biological value (BV=100).
⏰ When to Take Which Protein?
- Morning: Whey concentrate/isolate — quickly replenishes amino acid stores after overnight fasting.
- Before training: Whey isolate (30-60 min. before) — easily digestible, does not cause a feeling of heaviness.
- After the workout: Whey concentrate/isolate within 30-60 min. — the so-called "anabolic window".
- Before sleep: Micellar casein — slowly releases amino acids for 6-8 hours during sleep.
- Between meals: Casein or plant protein — maintains a feeling of satiety and a steady amino acid level.
