The Protein Puzzle: Do Shakes Work?

‍

Protein is the building block of muscle, and adequate intake is crucial for anyone engaged in regular exercise. But the question remains: do you need to get it from a shake?

‍

The Science Behind Protein Supplementation

Your body needs protein to repair and build muscle tissue after exercise. Research shows that consuming protein after resistance training can enhance muscle protein synthesis — the process by which your body builds new muscle.

While whole food sources of protein provide essential nutrients beyond just protein, shakes can be a convenient way to meet your daily requirements, especially for busy individuals. 

‍

How Much Protein Do You Actually Need?

‍

The most up to date evidence-based recommendations suggest:

• Sedentary adults: 1.0 g of protein per kg of body weight
• Recreational exercisers: 1.1-1.4 g per kg
• Those focusing on building muscle: 1.5-2.0 g per kg and occasionally above for athletes with very advanced training regimes and specific needs

For a 70kg (154lb) person who exercises regularly, this translates to roughly 100-140g of protein daily. To put this in perspective, a chicken breast - or an average size protein shake - contains about 25-30g of protein.

While increasing protein intake can support muscle development, studies indicate that intakes above 1.6g/kg/day provide diminishing returns in strength and hypertrophy gains, and over 2.0g additional benefits taper off completely, so there is no need to go crazy!

Types of Protein Supplements

‍

Not all protein supplements are created equal. Studies comparing these protein sources show differences in digestion speed, amino acid availability, and more. Here's a breakdown of the most common types:

‍

Whey Protein 

A fast-digesting, complete protein derived from milk. Available as concentrate (less processed, contains some lactose) or isolate (more processed, less lactose, higher protein content). One study found that whey protein supplementation did not significantly enhance myofibrillar protein synthesis or recovery parameters in resistance-trained men over a short-term training period. However, other studies suggest that whey protein can enhance whole-body protein metabolism and improve recovery of exercise performance over 24 hours post-exercise.

Casein Protein

Slow-digesting protein also derived from milk. Ideal for sustained release of amino acids, making it a good option before bed.

‍

Plant-Based Proteins

Options like pea, rice, hemp, and soy protein are suitable for vegans or those with dairy allergies. Often combined to create a complete amino acid profile. 

‍

Plant-Dairy blends

Blends of soy and dairy proteins have also shown promise in extending the period of muscle protein synthesis after training, potentially outperforming whey alone in certain contexts.

‍

Collagen Protein

Growing in popularity for joint health and skin benefits, though less effective for muscle building due to its incomplete amino acid profile.

‍

When to Use Protein Supplements

‍

Protein shakes can be particularly valuable in certain situations:

• When you struggle to meet your protein needs through whole foods
• For convenience when traveling or on busy days
• In the post-workout window when rapid absorption may be beneficial
• As a between-meal snack to help maintain protein distribution throughout the day

Remember that supplements should complement a diet rich in whole, nutrient-dense foods that provide a spectrum of macronutrients as well as vitamins and minerals beyond just protein.

Pre-Workout : Necessity or Nice-to-Have?

‍

Walk into any gym, and you'll see people sipping colorful drinks before their workout. But what's in these pre-workout supplements, and do they actually work?

‍

Common Pre-Workout Ingredients and Their Effects

• Caffeine: Probably the most effective pre-workout ingredient, caffeine enhances focus, reduces perception of effort, and can improve performance in both strength and endurance activities. Effective dose: 3-6mg per kg of body weight. For context, an espresso has around 200mg of caffeine, and therefore that would already be sufficient for a 70kg person.
• Beta-Alanine: Helps buffer acid in muscles, potentially delaying fatigue during high-intensity exercise lasting 1-4 minutes. The tingling sensation many people feel after taking pre-workout is often from beta-alanine. Effective dose: 3-5g daily.
• Citrulline Malate: Increases nitric oxide production, potentially improving blood flow to working muscles. Some studies show modest benefits for reducing soreness and improving endurance. Effective dose: 6-8g.
• Creatine: While typically thought of as its own supplement, many pre-workouts include creatine. We'll cover this in detail later. Effective dose: 3-5g daily.
• BCAAs (Branched-Chain Amino Acids): The evidence for BCAAs alone is mixed, with most research suggesting they're unnecessary if you're consuming adequate protein.

Pre-Workout: Timing and Considerations

‍

For optimal results, most pre-workout supplements should be consumed 30-60 minutes before exercise. However, individual responses vary based on metabolism, sensitivity to ingredients, and the specific formulation of the product.

However it is very important to note that the benefits of pre-workout supplementation is marginal at best, questionable at worst, and might be largely due to the placebo effect. Whilst caffeine does have concrete benefits, often pre-workout drinks have a substantial excess of caffeine, totally unnecessary for the performance benefits and in fact potentially hazardous at extreme doses.

‍

Coach's Tip

If you're sensitive to caffeine or train in the evening, look for stimulant-free pre-workout options. These typically rely on ingredients like citrulline malate, betaine, and electrolytes to enhance performance without affecting sleep.

‍

Pre-workout supplements can enhance your performance whether you're at the gym or working out at home with limited equipment. The key is matching the supplement to your specific workout needs.

Post-Workout Nutrition: Your Recovery Rituals

‍

While the "anabolic window" (the period immediately following exercise when nutrition supposedly has the greatest impact on recovery) isn't as narrow as once thought, post-workout nutrition still matters — especially if you're training frequently or intensely.

‍

What Your Body Needs After Exercise

After a challenging workout, your body prioritizes:

• Replenishing glycogen stores (carbohydrates)
• Repairing muscle damage (protein)
• Rehydrating (fluids and electrolytes)

Post-Workout Supplement Options

• Protein Shakes: A convenient option that provides rapidly digesting protein to jumpstart recovery. A dose of approximately 30g of high-quality protein (up to 50g in some studies) appears optimal to stimulate muscle protein synthesis in most adults following resistance training.
• Recovery Formulas: These typically combine protein with carbohydrates in a ratio designed to optimize recovery for both resistance and endurance training.
• BCAAs and EAAs: Essential amino acids (particularly leucine) can trigger muscle protein synthesis, though complete protein sources are generally far more effective.

Timing: Does the Post-Workout Window Matter?

Current research suggests that the post-workout "window" is wider than previously believed. For most recreational exercisers, consuming adequate protein within a few hours of training is sufficient. However, if you're training multiple times per day or in a caloric deficit, more immediate post-workout nutrition may be beneficial.

‍

Whole food sources can also effectively support post-exercise muscle remodeling, especially when timed appropriately within the broader recovery window. Learning to balance nutritional needs with occasional indulgences is crucial for sustainable fitness success, especially when developing your post-workout nutrition strategy.

Creatine: The Supplement That Lives Up to the Hype

Among all supplements, creatine stands out for its extensive research backing and proven effectiveness. Let's explore why this supplement deserves special attention.

What is Creatine and How Does It Work?

Creatine is a naturally occurring compound found in small amounts in certain foods (particularly meat and fish) and produced by your body. It plays a crucial role in energy production during high-intensity, short-duration activities like weightlifting or sprinting.

‍

Supplementing with creatine increases your muscles' phosphocreatine stores, which helps your body produce more ATP (adenosine triphosphate) — your cells' primary energy currency. This translates to:

‍

• Increased strength and power output
• Enhanced ability to perform high-intensity exercise
• Improved muscle growth over time
• Potentially faster recovery between sets

The Evidence Behind Creatine

Creatine is one of the most thoroughly researched supplements available, with hundreds of studies demonstrating its efficacy and safety. Research consistently shows that creatine supplementation can increase strength gains by 5-15% and improve high-intensity exercise capacity by 10-15% compared to training without it.

‍

Types of Creatine

While many forms exist, creatine monohydrate remains the gold standard — it's the most researched, most affordable, and most effective form. Other types like creatine HCL, ethyl ester, or buffered creatine claim better absorption or fewer side effects, but research hasn't consistently demonstrated advantages over monohydrate.

‍

How to Take Creatine Effectively

Loading Protocol

20g per day (divided into 4 doses) for 5-7 days, followed by a maintenance dose of 3-5g daily.

Simplified Protocol

3-5g daily without loading. This approach takes longer to fully saturate muscle stores (about 3-4 weeks) but is equally effective long-term and may cause fewer digestive issues.

‍

Creatine works through accumulation in your muscles over time, so consistency is key. It doesn't matter when you take it — pre-workout, post-workout, or any other time of day — as long as you take it regularly.

‍

Creatine is particularly beneficial for those focused on strength training and power movements, as it directly supports the energy systems used during these exercises.

Beyond the Basics: Other Supplements to Consider

‍

While protein, pre-workout formulations, and creatine get most of the attention, several other supplements may benefit specific fitness goals.

‍

Omega-3 Fatty Acids

These essential fats, found in fatty fish and some plant sources, offer numerous benefits:

• Reduced exercise-induced inflammation
• Improved recovery
• Enhanced cardiovascular health
• Potential improvements in body composition

Typical dosage: 1-3g of combined EPA and DHA daily.

‍

Vitamin D

Often called the "sunshine vitamin," vitamin D plays crucial roles in:

• Bone health
• Immune function
• Muscle function and recovery
• Hormone regulation

Many people are deficient, particularly in northern climates or those with limited sun exposure. Typical dosage: 1000-2000 IU daily, though individual needs vary based on current levels.

‍

Magnesium

This mineral is involved in over 300 enzymatic reactions in the body, including:

• Muscle contraction and relaxation
• Energy production
• Protein synthesis
• Sleep quality

Typical dosage: 200-400mg daily, with different forms (citrate, glycinate, etc.) offering varying benefits.

‍

HMB (Beta-Hydroxy Beta-Methylbutyrate)

A metabolite of the amino acid leucine, HMB may:

• Reduce muscle protein breakdown
• Support recovery, particularly during periods of caloric restriction
• Benefit those new to resistance training

Typical dosage: 3g daily, divided into three doses.

‍

These supplements can be particularly beneficial when paired with a comprehensive cardio routine, as they support endurance, recovery, and overall cardiovascular health.

Navigating the Supplement Market: Quality Matters

‍

With thousands of supplements on the market and minimal regulation, choosing high-quality products requires vigilance.

What to Look For In Supplements

• Third-Party Testing: Organizations like NSF Certified for Sport, Informed Choice, or USP verification indicate that products have been tested for banned substances and contain what they claim.
• Transparent Labels: Look for products that clearly list all ingredients and their amounts without hiding behind "proprietary blends."
• Minimal Additives: Fewer artificial colors, flavors, and fillers is generally better.
• Reputation: Established companies with strong reputations have more to lose from cutting corners.

Red Flags to Avoid

• Extreme claims that sound too good to be true
• Products marketed as "pharmaceutical grade" (a meaningless term in supplements)
• Excessive use of proprietary blends that don't disclose specific amounts
• Products claiming to be "banned substance free" without third-party verification

Coach's Tip

Start with the basics. Before investing in numerous supplements, focus on consistent training, adequate protein intake, and overall nutrition. Add supplements one at a time to assess their individual impact on your performance and recovery.

‍

Many experienced coaches wish they'd known the importance of quality over quantity when it comes to supplements when they first started their fitness journeys.

The Bottom Line: Supplements vs. Real Food

‍

While supplements can be valuable tools in your fitness arsenal, they should complement — not replace — a nutrient-dense diet.

‍

The Case for Food First

Whole foods provide:

• Complete nutrient profiles with vitamins, minerals, and phytonutrients
• Greater satiety and better appetite regulation
• Synergistic effects between nutrients that enhance absorption and utilization
• Fewer artificial ingredients and additives

When Supplements Make Sense

Supplements are most beneficial when:

• You struggle to meet specific nutrient needs through diet alone
• Convenience is a priority in certain situations
• You have specific performance goals that require targeted nutrition
• You have identified deficiencies through testing or professional assessment

Finding Your Personal Balance

The optimal approach combines the nutritional completeness of whole foods with the strategic use of supplements based on your individual needs, preferences, and goals.

‍

This food-first approach is especially important for those focusing on bodyweight training methods, where nutritional quality directly impacts performance and recovery.

Beyond Shakes: A Supplement Strategy That Works

‍

Supplements can be valuable tools in your fitness journey, but they're exactly that — supplementary to the fundamentals of consistent training, adequate nutrition, quality sleep, and stress management.

‍

Remember that the supplement industry is primarily driven by marketing, not science. The most effective approach is to:

1. Focus first on optimizing your overall diet and training
2. Identify specific areas where supplements might address gaps or enhance performance
3. Choose quality products backed by research
4. Monitor your results and adjust accordingly

At Zing Coach, we believe in evidence-based approaches to fitness and nutrition. While we recognize the potential benefits of strategic supplementation, we emphasize that no supplement can compensate for inconsistent training or poor nutrition.

‍

As you plan your fitness goals for the coming year, consider how strategic supplementation might support — but not replace — the foundational elements of your training program.
