Protein
Protein is one of the most important nutrients for anyone looking to support muscle growth, recovery, performance, and overall health. Whether you’re lifting weights, training for endurance, playing sport, or simply aiming to increase your daily protein intake, quality protein supplements make it easier to meet your goals. Research consistently shows that adequate protein supports lean muscle development, helps reduce muscle breakdown, improves recovery between sessions, and can assist with appetite control and healthy body composition.
At Sportsfuel, we offer one of the most comprehensive ranges of protein supplements in NZ. Our collection includes whey protein, casein protein, plant-based and vegan protein, protein bars, ready-to-drink (RTD) shakes, high-protein snacks, and mass gainers from trusted local and international brands.

Frequently Asked Questions
-
Protein supplements are used to help support muscle growth, recovery, strength, performance, calorie intake, and overall daily protein intake. They make it easier to meet protein requirements, especially for active individuals.
-
The best protein depends on your goals and dietary needs. Whey protein is fast-digesting and ideal post-workout, casein is slower-digesting and great before bed, and plant-based protein suits those who are dairy-free or vegan.
-
Protein supplements aren’t strictly necessary if you meet your protein needs through food, but they are a convenient and effective way to consistently support muscle growth and recovery.
-
Most active individuals benefit from around 1.4–2.2 grams of protein per kilogram of bodyweight per day, depending on training intensity and goals.
-
Protein can be taken any time of day. Many people use it in a morning smoothie for a high-protein breakfast, post-workout to support recovery, between meals to increase intake, or before bed (casein) to support overnight muscle repair.
-
Yes, protein bars, RTDs, and powders can all support muscle growth and recovery if they provide enough high-quality protein per serve.
Whey protein powders are highly bioavailable and rich in essential amino acids, especially leucine, which helps stimulate muscle protein synthesis. Many bars and RTDs also use whey or milk protein, making them similarly effective.
Some bars use soy protein isolate (a complete protein with good digestibility) or plant-based blends. These can still support muscle growth when total daily protein intake is sufficient. However, collagen protein is not a complete protein and is less effective for muscle building.
Powders usually offer better value per serve, while bars and RTDs provide added convenience. -
Whey protein contains all essential amino acids, is naturally high in leucine, and is highly bioavailable, which makes it particularly effective for stimulating muscle protein synthesis and supporting recovery after training. It’s often considered the gold standard for muscle growth due to its strong research backing and rapid digestion.
However, high-quality plant-based proteins can also effectively support muscle growth when total daily protein intake is sufficient. Well-formulated blends such as pea and rice protein provide a complete amino acid profile and can deliver comparable results over time. The best choice ultimately depends on your dietary preferences, digestive tolerance, and overall nutrition plan. -
Protein can support weight management by increasing satiety, helping preserve lean muscle mass, and supporting recovery during a calorie deficit.
-
For healthy individuals, protein supplements are generally considered safe to use daily when consumed within recommended protein intake levels as part of a balanced diet.
