Whey protein is the most popular sports supplement among athletes. It is a byproduct of cheese production that contains all the essential amino acids and is quickly absorbed by the body within 30–60 minutes after consumption.
Why You Should Take Whey Protein
Studies show that whey protein stimulates protein synthesis 68% more effectively than casein. Key benefits:
- Fast recovery—ideal after a workout
- High leucine content—a key amino acid for muscle growth
- Convenience—easy to prepare and take with you
- Digestibility — 95–100% biological value
Types of Whey Protein
Concentrate (WPC)—contains 70–80% protein, retains lactose and fats. The most affordable option with a good taste.
Isolate (WPI) — 90–95% protein, minimal lactose. Suitable for people with lactose intolerance; absorbed more quickly.
Hydrolysate (WPH) — pre-digested protein; absorbed the fastest, but the most expensive.
How to Choose a High-Quality Product
Check these parameters before buying:
- Ingredients — protein should be the first ingredient
- Protein content — at least 20–25 g per serving
- Certifications — NSF and Informed Sport guarantee quality
- Amino acid profile — full BCAA profile
- Solubility — high-quality protein mixes easily
When and how much to take
Optimal doses: 20–30 g of protein per serving. The best time to take it is within 30 minutes after a workout and between meals. To gain muscle mass, you need 1.6–2.2 g of protein per kilogram of body weight daily.
