Buying Guide: Key Purchase Considerations
- Calorie intake per serving: Weight gainers vary from around 400–1200 kcal per serving. Match calories to your daily target and training load to avoid unwanted fat gain.
- Protein content: Higher protein helps with muscle synthesis and satiety. Look for products delivering 30–45 g of protein per serving as a baseline, depending on serving size.
- Carbohydrate source and sugar content: Carbs expend energy for workouts and aid recovery; check for complex carbohydrate blends and lower added sugar where possible.
- Protein sources: Whey is common for fast absorption; blends including soy or casein add amino acid profiles and slower digestion.
- Creatine and other additives: Some mass gainers include creatine or digestive enzymes, which can support strength and digestion, but consider tolerance and dietary preferences.
- Flavor and mixability: Palatability influences consistency. Chocolate and vanilla flavours tend to mix well with water or milk and can affect daily adherence.
- Serving size and practicality: Larger tins reduce cost per serving but require planning for daily use. Consider liquid volume per shake and storage.
- Diet compatibility: Ensure the product fits your overall diet, including any lactose or gluten considerations and your total protein intake from all meals.
- Brand reputation and third-party testing: Look for established brands with transparent ingredient lists and reputable manufacturing standards.
