Protein Powder Selection Guide: Whey, Casein, Vegan, and More
Protein powder is the most popular supplement in the fitness world. However, finding the right product can be difficult with hundreds of options on the market. In this guide, we explain protein types, quality criteria, and how to choose the right one for your needs.
Why Is Protein Powder Necessary?
Basic Information
Protein powder is not a "miracle" - it's simply a convenient protein source. Your priority should always be getting protein from real food.
When Should You Use Protein Powder?
- If you can't meet your daily protein needs through food
- If you want fast protein intake after training
- If you need a practical solution during travel or busy work schedules
- If you want to build or maintain muscle mass
Daily Protein Requirements
| Activity Level | Protein/kg body weight |
|---|---|
| Sedentary | 0.8g |
| Lightly active | 1.0-1.2g |
| Regular exercise | 1.4-1.6g |
| Intense training | 1.6-2.0g |
| Professional athlete | 2.0-2.4g |
Protein Types
1. Whey Protein
Derived from milk, the most popular protein type. Ideal for post-workout due to its fast absorption.
Whey Concentrate
- Protein ratio: 70-80%
- Contains lactose and fat
- Most economical option
- Best taste
Whey Isolate
- Protein ratio: 90%+
- Low lactose and fat
- Faster absorption
- Suitable for those with lactose sensitivity
Whey Hydrolysate
- Protein ratio: 90%+
- Pre-digested
- Fastest absorption
- Most expensive option
SPECIFICATIONS
2. Casein Protein
Derived from milk, slow-digesting protein. Preferred for overnight muscle feeding.
PROS
CONS
3. Vegan Protein
Alternatives derived from plant sources, lactose-free.
Common Vegan Protein Sources
| Source | Protein/100g | Missing Amino Acids |
|---|---|---|
| Pea | 80g | Methionine |
| Rice | 75g | Lysine |
| Soy | 85g | Complete profile |
| Hemp | 50g | Lysine |
| Chia | 20g | - |
Combination Matters
Pea + rice protein combination creates an amino acid profile close to whey. That's why quality vegan proteins are usually in blend formulas.
4. Beef Protein
Derived from hydrolyzed beef protein. An alternative for those with milk allergies.
5. Egg Protein
Derived from egg whites. High bioavailability, medium absorption speed.
Quality Criteria
Label Reading Guide
Attention!
Products labeled "protein blend" or "proprietary blend" have mixed protein sources without specified ratios. Choose products with transparent labels.

When to Use Which Protein?
Timing Guide
| Time | Recommendation | Reason |
|---|---|---|
| Morning | Whey + carbohydrate | Break overnight fast |
| Pre-workout (1-2 hours) | Whey | Amino acid pool |
| Post-workout (30 min) | Whey Isolate | Fast absorption |
| Midday | Whey or Casein | Meal supplement |
| Pre-sleep | Casein | Overnight feeding |
Anabolic Window Myth
The "you must take protein within 30 minutes" myth is largely exaggerated. Total daily protein intake is as important as timing.

Things to Consider
Side Effects
Excessive protein intake can affect kidney health (especially with existing kidney problems). Don't exceed 2-2.5g/kg per day and drink plenty of water.
Common Mistakes
- Relying only on protein: Real food should always be priority
- Excessive dosage: Portions over 40g are wasteful, absorption decreases
- Not counting calories: Protein powder also contains calories
- Cheap product obsession: Low-quality protein isn't worth the money
