Choosing a protein powder can be confusing when different products offer different protein amounts, ingredients, serving sizes, flavors, and formulas. A simple protein powder checklist can make the comparison easier by helping you focus on what is actually inside the package rather than relying on the front label alone.
Before choosing a product, check the protein source, protein amount per serving, ingredient list, nutrition facts, allergens, and serving information. These details can help you understand whether a product fits your dietary preferences and intended use. Myprotein offers several protein options, including Impact Whey Protein and Impact Whey Isolate, making label comparison especially useful when exploring the range.

Why a Protein Powder Checklist Matters
Protein powders can look similar while having noticeably different nutritional profiles. Two products may both be described as whey protein, yet one may contain whey concentrate while another uses whey isolate.
A useful checklist helps you compare products on consistent criteria:
- Protein source and amount
- Ingredient list
- Serving size

- Carbohydrates, fats, sugars, and sodium
- Allergens and dietary suitability
- Price and value per serving
Looking at the complete nutrition panel gives you a better picture than focusing only on the protein number highlighted on the package.
1. Check the Protein Source
Start by identifying the type of protein used. Common options include whey concentrate, whey isolate, casein, and plant-based proteins.
Myprotein’s Impact Whey Protein is a whey protein concentrate product. One current vanilla listing provides 20g of protein per 25g serving, while its ingredient list identifies whey protein concentrate as the primary ingredient.
Impact Whey Isolate is a different option. A current Myprotein Australia listing provides 25.2g of protein per 30g serving and uses whey protein isolate as its primary ingredient.
The important point is not that one type is automatically right for everyone. Instead, understand the protein source and compare it with your own dietary preferences.
2. Compare Protein Per Serving
Never compare powders only by container size. Check the serving size and protein provided per serving.
For example, a current Impact Whey Protein listing provides 21.7g of protein in a 30g serving, while the listed nutrition values can vary between flavors and product versions.
This is why reading the exact product label matters. A larger tub does not automatically mean more protein per serving.
Also compare protein per 100g when evaluating different products. This can provide a more consistent comparison when serving sizes differ.
3. Read the Full Ingredient List
The ingredient list can tell you much more than the product name.
Look for the main protein ingredient first, then review flavorings, sweeteners, emulsifiers, cocoa, or other added ingredients. For example, Myprotein’s vanilla Impact Whey Protein listing includes whey protein concentrate, lecithin, flavoring, and sucralose.
If you have specific dietary requirements or ingredient preferences, this step becomes especially important.
4. Check Allergens and Dietary Information
Protein powders can contain common allergens. Whey products are milk-based, and some Myprotein products also list soy through ingredients such as soy lecithin.
For example, Myprotein’s Impact Whey Isolate listings identify milk and soy in their allergen information.
Always read the current product label before choosing a powder, particularly if you need to avoid specific ingredients.

5. Compare the Complete Nutrition Panel
Protein is important to compare, but it should not be the only number you examine.
Check:
- Calories or energy
- Protein
- Carbohydrates
- Sugars
- Fat
- Sodium
Current Myprotein listings show that these values can differ between products and flavors. For example, one Impact Whey Isolate listing provides 25.2g protein, 0.3g fat, and 1.1g carbohydrates per 30g serving.
Comparing the complete panel helps you understand what you are actually getting from each serving.
6. Check Serving Size, Price, and Availability
Finally, look beyond the headline price. Compare the package size, number of servings, serving size, and price per serving where available.
Prices and availability can change, so check the current store listing before making a decision. Myprotein Australia currently lists multiple Impact Whey Protein and Impact Whey Isolate sizes and flavors, but stock status can vary between products.
This approach makes it easier to compare value without assuming that the largest package is automatically the most economical.
How Myprotein Fits the Checklist
Myprotein provides multiple protein products that can be compared using the same six-point checklist. Its Impact Whey Protein range includes whey concentrate products, while Impact Whey Isolate provides an isolate-based alternative.
Rather than choosing based only on brand recognition or flavor, review the specific product page, nutrition panel, ingredients, allergen information, serving size, current price, and availability.

Frequently Asked Questions
What should I look for first in protein powder?
Start with the protein source and amount per serving. Then check the ingredient list, allergens, complete nutrition panel, and serving size.
Is more protein per scoop always better?
Not necessarily. Serving size and the rest of the nutrition panel also matter. Compare products using both per-serving and per-100g information.
What is the difference between whey concentrate and isolate?
They are different forms of whey protein. Their nutritional profiles and processing can differ, so compare the exact product label rather than assuming they are interchangeable.
Should I check allergens in protein powder?
Yes. Always review the current ingredient and allergen information, especially if you need to avoid milk, soy, or other ingredients.
Does protein powder replace a balanced diet?
Protein powder is a supplement rather than a complete replacement for a varied diet. Myprotein’s product information also describes these products as supplementary sports foods to be used alongside a nutritious diet.
