help Optimum Nutrition Pro Gainer FAQ
How much protein does Optimum Nutrition Pro Gainer provide per serving?
Each serving typically provides around 50-55 grams of protein, derived from a blend of whey protein concentrate, whey isolate, micellar casein, and egg white proteins, offering both fast and slow-digesting protein sources.
When is the best time to take Pro Gainer for maximum benefits?
The optimal times are immediately post-workout for muscle recovery or between meals to increase daily calorie and protein intake. Taking it before bed can also support overnight muscle recovery due to the casein content.
Is Pro Gainer suitable for cutting or weight loss phases?
While primarily designed for mass gaining, the higher protein ratio means it can be used during cutting with portion control. However, standard weight gainers with higher carb content are generally better suited for bulking phases.
How does Pro Gainer compare to standard weight gainers?
Pro Gainer distinguishes itself with a higher protein-to-carbohydrate ratio (approximately 1:2) compared to traditional weight gainers (often 1:5 or higher), making it better suited for lean muscle gains with less fat accumulation.
Does Pro Gainer contain any allergens?
Yes, it contains milk (whey and casein) and egg proteins, making it unsuitable for individuals with dairy or egg allergies. It is also manufactured in facilities that process soy and wheat.
