Overall Results


Brand Country of Origin

This refers to where the brand operates and conducts manufacturing. This data does not contribute to the overall results.Comparison of whey protein brand country of origin including Optimum Nutrition, LeanFit, Dymatize ISO100, Thrive Whey Isolate, Revolution Nutrition High Whey, Naked Whey, and BioSteel Whey Protein in Canada.

Section 1: Product Performance

Protein Per Serving

Here are the grams of protein per 32 g net weight of each product.

EAAs Per Serving

Essential amino acids (EAAs) are the nine amino acids the body cannot produce itself and must obtain from the diet; they are important because they are the building blocks required for muscle building and recovery (muscle protein synthesis). Higher EAA levels mean the protein is providing more of these building blocks.

The graph below shows the grams of EAAs per 32 g net weight of each product.

BCAAs Per Serving

Branched-chain amino acids (BCAAs) are three essential amino acids (leucine, isoleucine, and valine) that play a key role in muscle protein synthesis. Leucine in particular acts as the primary trigger for this process, meaning higher BCAA levels can help stimulate muscle building and recovery.

The graph below shows the grams of BCAAs per 32 g net weight of each product.

Kcals & Macros Per Serving

Calories and macronutrients per serving reflect how efficiently a protein powder delivers protein relative to fats and carbohydrates. Lower calories and fewer carbs or fats generally indicate a purer protein source.

The graph below shows the kcals, fat, carbohydrate, and sugars per 32 g net weight of each product. The score is based on the total kcals per serving.

Section 2: Product Quality

Whey Type

Whey protein is primarily produced in two forms: concentrate and isolate. Isolate is purer and contains a higher percentage of protein and fewer fats and carbohydrates than concentrate. Because isolate is purer and contains less lactose, it is easier for many people to digest. Some brands also use hydrolysed whey, which in theory is broken down faster, but in reality this makes no meaningful difference and therefore is not scored differently.

Full points are awarded for 100% isolate, 7 points for a blend of isolate and concentrate with more isolate than concentrate, 6 points for a blend with more concentrate than isolate, and 5 points for 100% concentrate.

Non-Medicinal Ingredient Quality

Non-medicinal ingredients are the flavourings, sweeteners, and additives used to improve taste and texture. Higher quality products avoid artificial sweeteners, artificial flavours, maltodextrin, modified food ingredients, and vegetable oils, which add no nutritional value and are often used to mask lower quality formulations or enhance taste at the expense of the product’s overall health quality. 

The graph below depicts the non-medicinal ingredient quality of each product. Below the graph is a table showing the ingredients used and the associated scoring penalties for artificial or modified ingredients.

Use of Dairy Hormones

Recombinant bovine growth hormone (rBGH), also known as recombinant bovine somatotropin (rBST), is used on some dairy farms to increase milk production. It is banned in the European Union, although it is still used in some U.S. dairy production. Studies have shown that treatment with rBST/rBGH can lead to measurable biological changes, including slightly higher IGF-1 levels in milk and detectable changes in gene expression in treated cows (1) (2). While these differences may be small, they are measurable.

High-quality, health-conscious whey brands generally source whey from cows not treated with rBST/rBGH.

The graph below shows whether or not the whey is certified hormone free.

Third Party Testing

Third-party testing refers to independent laboratory analysis used to verify that a supplement contains what the label claims and is free from contaminants such as heavy metals, microbes, and contaminants. Brands that publish full test panels provide the highest level of transparency. 

For the full third-party testing notes for each product, as well as the scoring key, view the accompanying data sheet summary tab.

Taste

Taste was assessed across the following metrics: Sweetness strength, flavour strength, and texture. Then, a score was assigned for overall enjoyability. 

The graph below shows the overall enjoyability score. The detailed notes for each product's sweetness stength, flavouring strength, and texture are available in the appendix

Cost Per Kilogram

The graph below shows the cost per 1 kg of each product. Note that it is very common in whey protein brands to use low weights in very large tubs to give the illusion of value; therefore, this shows the true cost.

Overall Results

Overall comparison and ranking of whey protein powders in Canada including Thrive Whey Isolate, BioSteel, Dymatize ISO100, LeanFit, Revolution Nutrition, Naked Whey, and Optimum Nutrition.

🥇 Thrive Natural Whey Protein Isolate takes first place. Scoring near the top for every metric, with 25.4 g of protein, 12.7 g of EAAs, 5.9 g of BCAAs, only 118 kcals, 100% whey isolate, no artificial ingredients, hormone-free whey, enjoyable taste, and a cost of $69.99 per kg, it scores 87% in the analysis. 

🥈BioSteel takes second place. Scoring highly for protein content with 26.5 g, 12.9 g of EAAs and 5.9 g of BCAAs, 121 kcals, with no artificial ingredients, and hormone free whey. The product ranked midway for whey type, using a blend of isolate and concentrate, and cost at $66.12 per kg. But scored low for taste enjoyability, and conducts no third-party testing beyond banned substance testing. 

🥉 Dymatize takes third place. Scoring highest for protein content (26.7 g) and kcals content at 110 kcals, and scored high with 12.5 g of EAAs and 5.9 g of BCAAs, and used 100% whey isolate. However, the product performed poorly for non-medicinal ingredients with artificial flavours and sweeteners, does not use certfiied hormone free whey, conducts no third party testing beyond banned substance testing, and costs $103.26 per kg. 

Products to avoid:

Optimum Nutrition Gold Standard Whey

After conducting this analysis, I was very surprised at the amount of poor-quality ingredients in Optimum Nutrition’s Gold Standard Whey. This is the number 1 selling whey protein worldwide, but it is certainly not the gold standard of what whey should be given the non-medicinal ingredient list (natural flavour, artificial flavour, sunflower or soy lecithin, sunflower oil, maltodextrin, modified food starch, dipotassium phosphate, tricalcium phosphate, tocopherols, guar gum, acacia gum, xanthan gum, sucralose, acesulfame potassium). In addition the product lacks third-party testing for metals, contaminants, and microbes, and has no certification for hormone-free dairy.

Data Sheet

For the full data set used to build this article, view this data sheet. The sheet includes a greater level of detail than the article. The 'summary' tab best shows the data, and has notes which can be viewed by hovering over each table.

Taste

Here are the detailed notes from the taste testing panel:

Optimum Nutrition

Optimum Nutrition was one of the sweetest samples, scoring 8/10 for sweetness, likely due to sucralose (artificial sweetener).

Flavour strength was also 8/10, but the vanilla flavour did not come across as natural. Instead, it was described as artificial, with some honey-like notes and a noticeable aftertaste. 

The texture was thicker and more viscous than most of the other samples. 

Overall enjoyability was low at 3/10, with the testers indicating they would be unlikely to drink it on its own.

LeanFit

LeanFit had a balanced sweetness strength, scoring 5/10, with a 5/10 flavour strength. 

The vanilla flavour was clear but not overly strong, and it was described as mild and natural tasting. 

The texture was smooth and uniform. 

Overall enjoyability was 7/10, making it one of the most pleasant samples in the tasting.

As it's not overly sweet or strong, it's a good option for both smoothies and drinking on its own.

Dymatize

Dymatize was one of the sweeter samples, with 8/10 sweetness and 8/10 flavour strength, likely due to artificial sweetener and flavour.

The vanilla flavour was described as artificial and quite concentrated, with a slight coconut-like note. 

The texture was smooth and uniform. 

Overall enjoyability was 6/10. It was drinkable but the sweetness and artificial flavour limited its appeal.

Thrive

Thrive had a relatively mild sweetness, scoring 4/10, and a 4/10 flavour strength. 

The vanilla flavour was fairly subtle. 

The texture was smooth and slightly milky. 

While the flavour was not particularly strong, the lighter sweetness made it easy to drink. 

Overall enjoyability was strong at a 7/10.

Like LeanFit, as it's not overly sweet or strong, it's a good option for both smoothies and drinking on its own.

Revolution Nutrition

Revolution Nutrition had 6/10 sweetness strength and 7/10 flavour strength. 

The vanilla flavour came across as authentic and enjoyable, with a smooth texture. 

Overall enjoyability was 8/10, making it one of the better-liked samples.

NAKED

Naked had almost no sweetness, scoring 1/10, and 1/10 flavour strength. 

The flavour was extremely mild, almost neutral, and was compared to water or skim milk.

The texture was smooth but slightly thinner than the other samples. Because it has no gum, the whey does split apart, which doesn't look very nice, but it still had a good texture.

Overall enjoyability was 4/10. It was drinkable, but not particularly appealing on its own. However, it is the most neutral and would be ideal for smoothies. 

BioSteel

BioSteel had 5/10 sweetness strength and 8/10 flavour strength. 

Despite the strong flavour, it was described as artificial and not particularly vanilla-like. 

The texture was smooth, although some slight separation was noted. 

Overall enjoyability was 2/10, making it one of the least enjoyable samples in the tasting.
