Whey protein

According to the position of the International Society of Sports Nutrition (ISSN), consuming 20-40 grams of whey protein after a workout has been shown to stimulate muscle growth and recovery. Whey protein is a complete protein source, rich in essential amino acids, especially leucine, which is key for activating protein synthesis. Its rapid digestibility makes it ideal for consumption around workouts, ensuring a quick supply of building blocks to the muscles.
In my practice with athletes from various sports, I observe that whey protein is an indispensable part of their recovery protocol. It not only aids recovery but also contributes to maintaining lean muscle mass during periods of caloric deficit, and improves strength performance. The EFSA also confirms the benefits of proteins for maintaining and growing muscle mass.
The choice of appropriate whey protein depends on individual goals and tolerance. Concentrate is an economical option with good protein content, while isolate offers higher purity and less lactose. Hydrolysate is the fastest-digesting, ideal for people with sensitive stomachs or those needing maximum fast recovery. For optimal results, dose between 20-40 grams, distributed throughout the day, depending on your total protein intake and training volume.

Whey Protein — Complete Guide
Whey protein is the fastest-absorbing type of protein with the highest biological value (BV ~104). It is ideal for consumption immediately after a workout, when muscles are most receptive.
Concentrate, Isolate, or Hydrolyzate?
- Concentrate (WPC) — 70-80% protein, low in lactose and fat. Best price/quality ratio.
- Isolate (WPI) — 90%+ protein, under 1% lactose. We recommend AllMax IsoFlex (cross-flow microfiltration) and Ultimate ISO Sensation 93.
- Hydrolyzate (WPH) — pre-digested peptides for maximum fast absorption. AllMax Hydro Pure is the gold standard.
Recommendations from SportZone Experts
For advanced trainees and people with lactose intolerance, choose pure isolate from AllMax or Ultimate Nutrition. For beginners — Prostar 100% Whey offers an optimal concentrate + isolate combination at an affordable price.
All our whey products come with purity certificates (cGMP, NSF) and are sourced directly from the manufacturer — exclusive import for Bulgaria.
