The 7 Best Protein Supplements For Men [Australia 2025]

Struggling to hit your daily protein targets on meals alone? You’re not the only one. These days, protein supplements are basically gym currency. Nearly half of all gym-goers are reaching for a shake or powder to help smash their fitness goals, and men are leading the charge. Almost 70% of them use protein supplements in some form, compared to just 35.6% of women.

The catch is; Walk into any supplement store and you’ll be flooded with more tubs, bags, and “miracle blends” than you can shake a shaker at, and picking the right one can feel like trying to find a needle in a haystack.

For guys who train hard, the sweet spot is 2.2–3.4 grams of protein per kilo of bodyweight every day. If your regular meals aren’t hitting that, a solid protein supplement can be the difference between gains and… well, no gains.

However, most brands will leave you scratching your head; confusing labels, conflicting claims, and zero guidance on what actually works. That’s why we’ve put together this guide: to help you find the protein supplement that actually gets results.

Protein and Its Role in Men’s Health

Protein is your body's fundamental building block that supports growth and maintenance. It keeps your muscles, hormones, and even your metabolism running at full throttle. Unlike carbs and fats, protein is made up of amino acids, which your body needs for just about everything: repairing tissue, producing hormones, and keeping your energy up.

Your body uses 20 amino acids to function properly. It can make 11 of them on its own but the other 9 need to come from your diet. For men, in particular, adequate protein intake also plays a key role in healthy testosterone production. Without enough protein, you’re risking slower recovery, weaker gains, and even dips in energy and strength.

Not all protein sources are created equal, though. Complete proteins (like meat, eggs, and fish) have all the essential amino acids your body needs in the right proportions. Most plant proteins, with the exception of soy and quinoa, are considered incomplete as they lack one or more essential amino acids.  That’s why the quality of your protein source (whether food or supplements) matters just as much as the quantity.

Protein also has a unique advantage over carbs and fats: your body burns 20–30% of protein calories just digesting it, compared to only 5–10% for carbs and 0–3% for fats. In other words, eating more protein naturally boosts your metabolism and makes fat loss a whole lot easier.

How Protein Works in Your Body

Muscle Repair & Growth: Every workout leaves microtears in your muscle fibres. Protein provides the amino acids needed to repair and strengthen these fibres, a process called muscle protein synthesis (MPS). This is how muscles grow bigger and stronger. Research shows 20–40g of high-quality protein post-training is the sweet spot.

Fat Loss & Body Composition: Protein keeps you fuller for longer and prevents your body from burning muscle when you’re cutting calories. This makes fat loss more efficient and sustainable.

Hormone Support: Amino acids are the raw material for hormones, including. Adequate protein intake supports muscle strength, bone density, and energy levels. Insufficient intake, on the other hand, can throw off your hormone balance and overall performance.

How Much Protein Do Men Really Need?

Your protein needs aren’t one-size-fits-all. They depend on your lifestyle, training, and age:

• Sedentary men: ~0.8g per kg of bodyweight daily (the bare minimum)
• Recreational exercisers: 1.0–1.5g/kg
• Endurance athletes: 1.2–1.6g/kg
• Strength athletes & bodybuilders: 1.6–2.2g/kg
• Men over 50: Add 25–50% more to offset muscle loss from ageing (anabolic resistance)

👉Pro tip: it’s not just how much protein you eat, but when you eat it. Studies show spreading protein across the day does more for muscle building than cramming it all into one or two big meals.

Types of Protein Supplements

Whey Protein

Whey is the most popular protein supplement. Derived from milk during the cheese-making process, it’s a complete protein, meaning it provides all nine essential amino acids your body needs. It’s also digested quickly, making it ideal for post-workout recovery and stimulating muscle protein synthesis.

Whey comes in three main forms:

• Whey Protein Concentrate (WPC): Contains around 58–89% protein, with some fat and lactose. Affordable and effective, it’s great for beginners and men looking to build muscle without breaking the bank.
• Whey Protein Isolate (WPI): Delivers 90–95% protein with minimal fat and lactose. A smart choice for those who want lean muscle growth while keeping carbs and fats low.
• Whey Protein Hydrolysate (WPH): The premium option, containing up to 99% protein. It’s pre-digested through hydrolysis, allowing faster absorption. This makes it especially beneficial for immune support and advanced recovery.

Casein Protein

Casein (also found in dairy) differs from whey because it digests slowly, releasing amino acids steadily over 6–12 hours. This makes it an excellent choice before bed or during long gaps between meals, as it helps prevent muscle breakdown. Micellar Casein is the purest form, forming a gel in the stomach that prolongs digestion (about twice as long as whey.) Each serving typically provides around 24–25g of protein.

Casein is particularly useful for:

• Overnight muscle recovery and growth
• Maintaining stable protein levels between meals
• Protecting lean muscle during fat loss phases

It also contains bioactive peptides that may support heart health by lowering blood pressure.

Plant-Based Protein

For men following vegetarian or vegan diets, plant-based protein supplements are effective alternatives. While many plant proteins are incomplete (missing one or more essential amino acids), some offer complete profiles or can be blended for balance.

Popular options include:

• Soy Protein: A complete protein with all essential amino acids, making it comparable to animal sources.
• Pea Protein: Easily digested and a solid substitute for soy or dairy proteins.
• Hemp Protein: A complete protein that also provides essential fatty acids for overall health.
• Smooth Protein™(watermelon and pumpkin seed): The premium vegan protein at the heart of Protein of the Gods: Ultimate Harvest. Specially processed to reduce bitterness and grit, it delivers a silky-smooth texture with improved mouthfeel and a clean finish. Smooth Protein™ make shakes more enjoyable and versatile while maintaining high nutritional value.

Though plant proteins often have slightly less protein per serving, they add valuable extras like fibre, antioxidants, and micronutrients. Research also shows pea and rice protein can be just as effective as whey for building muscle.

Collagen Protein

Collagen is unique because it comes from connective tissues such as skin, bones, and ligaments (typically from bovine or marine sources). It’s rich in amino acids like glycine, proline, and hydroxyproline, and is usually hydrolysed for better absorption.

Collagen supports:

• Joint and tendon health
• Gut recovery
• Skin, hair, and nail condition

Recommended dosages vary depending on your goals:

• 2.5–10g daily for skin health
• 15–20g for muscle support
• 2.5–5g for joint health

Egg Protein

Egg protein is made by dehydrating egg whites into a powder. Like whey, it’s considered a complete protein, containing all nine essential amino acids in the right ratios. It’s also naturally fat-free, cholesterol-free, and lactose-free, making it an excellent choice for men who want a clean, allergen-friendly option.

Key benefits of egg protein:

• High biological value, meaning your body absorbs and uses it very efficiently
• Supports muscle growth and repair
• Naturally low in carbs and fat, great for lean muscle goals
• Ideal for men who can’t tolerate dairy but still want an animal-based complete protein

Protein Blends

Protein blends combine different sources, such as fast-digesting whey with slow-release casein. This creates a sustained release of amino acids, giving you both immediate recovery after training and longer-lasting support between meals.

Blends are particularly useful for men with intense training schedules or long periods without eating, as they provide consistent muscle fuel over several hours.

Comparison At A Glance

Popular Protein Supplement Forms

• Protein Powders: Protein powders (like Protein Of The Gods) are by far the most popular form. They’re versatile, affordable, and deliver a high amount of protein per serving. Mix them with water, milk, or even add them to foods like oatmeal, smoothies, or pancakes.
• Ready-to-Drink (RTD) Shakes: Pre-mixed protein shakes are all about convenience. Just grab, shake, and go. They’re perfect for busy men who want protein on the move, though they tend to cost more than powders. Beyond convenience, many RTDs also come fortified with extra vitamins and minerals, giving you a well-rounded nutritional boost.
• Protein Bars & Functional Foods: Protein bars are another portable way to combine protein with carbs and fats. They stay fresh on the shelf and often include ingredients like nuts, seeds, dried fruits, and protein isolates. You’ll find options made from whey, milk, egg whites, soy, or pea protein. Research shows that protein-rich snacks not only curb hunger but may also support weight management.
• Protein Capsules: Protein capsules are a less common option, but they appeal to men who want zero prep work. Typically made with concentrated hydrolysed protein or amino acid compounds, they’re easy to carry and allow for precise dosing. However, capsules contain much less protein per serving than powders or bars, so they’re usually used to top up specific amino acids rather than replace primary protein sources.
• Protein Gels & Sachets: Protein gels are lightweight packets designed for quick use during training or endurance events. They’re especially popular with runners and cyclists, as they can be consumed without extra water and fit easily into pockets or belts. Some gels also contain caffeine for an added performance boost. Athletes often test them during training before using them in competition, to make sure their stomachs can handle the formula.

Key Factors to Consider When Choosing a Protein Supplement

Picking the right protein supplement doesn’t have to be confusing. With so many options on the market, it helps to know exactly what to look for so you can hit your fitness goals without wasting money or dealing with a shake you hate. Here are the key things to keep in mind:

1. Protein Content and Amino Acid Profile

At the end of the day, protein is the ingredient. Check how much protein you get per serving and whether it’s a complete protein (one that has all nine essential amino acids your body can’t make on its own.) Complete proteins like whey, egg, and soy are perfect for building and repairing muscle.

Also, if you’re focused on muscle growth, pay attention to BCAAs (branched-chain amino acids like leucine, isoleucine, and valine). These help kickstart muscle protein synthesis and speed up recovery.

2. Taste, Mixability, and Digestibility

Let’s be honest, if your protein tastes terrible or leaves a chalky mess in your shaker, you’re less likely to use it consistently. Look for products that:

• Mix smoothly with water, milk, or your favourite smoothie
• Come in flavours you actually enjoy (chocolate, vanilla, salted caramel, or even cookies & cream)
• Are gentle on your stomach

Some supplements even include digestive enzymes or hydrolysed protein, which help your body absorb the protein faster and cut down on bloating.

3. Added Ingredients: Sugars, Fillers, and Artificial Flavours

Not all protein powders are created equal. Some sneak in extra sugar, fillers, or artificial flavours that can ruin the nutritional value

• Extra sugar = extra calories and energy spikes
• Fillers = less actual protein per scoop
• Artificial flavours or colours = potential digestive issues or weird aftertaste

A clean, minimally processed protein gives you the most bang for your buck and keeps your nutrition goals on track.

4. Price and Value for Money

Protein powders can vary from bargain-bin to premium pricing. But, don’t just look at the price tag; check the value you’re getting:

• How many grams of protein per serve?
• Quality of the protein (whey isolate vs concentrate, hydrolysed vs non-hydrolysed)
•  Extra benefits like BCAAs, vitamins, or digestive support

Sometimes it’s worth paying a bit more for a product that actually works and tastes great.

5. Certification, Lab Testing, and Quality Standards

When it comes to supplements, safety matters,  especially if you train hard and rely on them to hit your fitness goals. In Australia, supplements cover a huge range of products: vitamins, minerals, protein powders, and other sports nutrition goodies. Some are regulated as foods, and some as medicines, depending on what’s in them and what they’re meant to do.

If a product is considered a medicine, you’ll see an ‘AUST’ number on the label. This means it’s listed on the Australian Register of Therapeutic Goods (ARTG) and has been approved for sale by the TGA. Products can be:

• AUST-R: Registered medicines
• AUST-L: Listed medicines

Even for protein powders and sports supplements classified as foods, it’s smart to look for extra quality measures. A reliable protein should be:

• Third-party tested to make sure there are no banned substances, hidden nasties, or misleading labels
• Certified by groups like Informed Choice or Informed Sport
• Made under strict quality control, so what’s on the tub actually matches what’s inside

Taking a little time to check these details means you can focus on your training and recovery, not worrying about what’s in your protein shake. Clean, tested supplements give you peace of mind and let you get on with smashing your goals.

Protein Supplements for Specific Goals

Muscle Building

If your goal is bigger, stronger muscles, focus on high-quality protein that your body can absorb quickly. Whey protein is a standout choice because it digests fast and delivers the essential building blocks your muscles need.

While total daily protein matters most, consuming protein soon after a workout can give your muscles an extra boost, especially if you train on an empty stomach. Incorporating protein consistently across the day ensures your body has what it needs to repair and grow muscle tissue efficiently.

Weight Loss and Fat Management

Protein isn’t just for building muscle; it’s also an effective tool for managing weight. High-protein supplements help keep you feeling fuller for longer, which can reduce cravings and prevent overeating.

Low-calorie protein options give you a substantial protein hit without adding too many extra calories. They also help protect lean muscle while you’re losing weight, ensuring that most of the weight you shed comes from fat stores. Plus, digesting protein naturally burns more calories than carbs or fats, giving your metabolism a little boost along the way.

Endurance and Athletic Performance

For athletes focused on endurance (think runners, cyclists, or triathletes), protein supports both recovery and stamina. Combining protein with carbohydrates during or after training helps repair muscles and replenish energy stores, so you’re ready for your next session faster.

Certain supplements, like those rich in key amino acids, can also help reduce fatigue and muscle soreness. The right protein strategy allows endurance athletes to recover efficiently while maintaining strength and performance over long periods of training.

Aging Men

As men age, the body becomes less efficient at using protein, making it even more important to focus on intake and timing. High-quality proteins like whey and casein can help preserve muscle mass, maintain bone strength, and support overall vitality.

Consuming protein consistently throughout the day, and including a slow-digesting protein before bed, can help older men maintain muscle and support recovery, even if activity levels aren’t as high as they once were.

Finding the Right Protein Supplement for You

The protein supplement market in Australia moves fast, and it can feel like a jungle out there. Men are looking for products that not only deliver results but also fit into busy lifestyles.

Which supplement works best comes down to your goals and habits. Fast-digesting protein helps fuel recovery right after a workout, while slow-release formulas support overnight muscle repair. Specialised blends can even tackle multiple goals at once, making it easier to stay on track without juggling a dozen tubs.

Consistency is key. The most expensive, high-tech protein won’t do much if you only use it occasionally. Protein supplements are tools to complement a well-rounded diet, not replace it, so regular use alongside whole foods is the real game-changer.

Unlike many brands that leave you guessing, Hercules Supplements actually cares about your results. Our range is designed to support your goals with quality, transparency, and ease of use. Shop today and find the protein that works for you.
