Ranking of popular cost-effective proteins! Recommended WPC Whey by price per gram of protein

Ranking of popular cost-effective proteins! Recommended WPC Whey by price per gram of protein

The cosmetic value of protein cannot be judged solely by the selling price. What matters is how much protein you get for the price you pay. In this article, we will compare the most standard of powdered proteins, WPC whey protein. The standard product, SAVAS Whey Protein 100, is used as a benchmark, and the cosmetics of each brand are organized in a ranking format based on price per gram of protein.

Key Points for Choosing a Cost-effective Protein 1Manufacturers that are strong in direct sales and e-commerce often offer the best value for money

It is easy to make a bad decision when choosing a protein product based on the price of a single bag alone. What you should look at is how much protein you get for the price you pay. In this article, we compared the real cosmetic value of each product based on “price per gram of protein. In particular, brands that are developed around the manufacturer’s official sales page on direct sales sites or Amazon often offer lower prices than standard brands with widespread in-store distribution. The top products in this survey were all from brands whose strength lies in direct sales and EC-centered sales.

Points for choosing a cost-effective protein 2If you want to keep going, aim for a large-capacity type of around 3 kg

Even with the same brand of WPC whey protein, the price per gram of protein varies greatly between a regular capacity of around 1 kg and a large capacity of around 3 kg. The price per gram of protein varies greatly. If you assume continuous consumption, this difference cannot be ignored on a multi-month basis. If you are looking for a cost-effective option, the large volume is a strong choice. On the other hand, if you can’t finish it because you don’t like the taste, the sweetness doesn’t suit you, or you get bored halfway through, the cost performance will quickly deteriorate. It is important to do research before purchasing, such as looking at reviews of buyers, choosing the manufacturer’s standard popular flavors, and trying a small volume product first.

Key Points for Choosing a Costa Protein 3Protein content can vary by flavor

One thing that can be easily overlooked is the difference in protein content between different flavors. Even within the same series, same volume, and same price, the protein content may vary slightly by flavor, such as chocolate, yogurt, berry, or milk tea. This is because the ratio of whey ingredients may change due to the addition of ingredients such as cocoa powder, fruit juice powder, acidifiers, flavors, sweeteners, etc., which are used to create flavors. If you want to close the unit price as much as possible, you should look not only at the product price, but also at the Nutrition Facts label of the flavor you are considering.

Plain and non-flavored products are very cost-effective per gram of protein because of their low selling price to begin with. Avoiding flavors and sweeteners is also an advantage. However, it is also true that for many people it is easier to choose flavored flavors that can be dissolved in water or milk and consumed as is. In this study, we compared the flavored flavors that are popular or symbolic of each brand. Since flavored flavors do not necessarily have the same amount of protein, the ranking was estimated based on the nutritional composition of the representative flavors shown in the text. Since taste, sweetness, solubility, and compatibility with body constitution vary greatly among individuals, these are supplemented as characteristics of each product rather than rankings.

Benchmark: price sensitivity of a classic proteinSAVAS Whey Protein 100 980g / 2,200g

SAVAS Whey Protein 100 should be looked at as a benchmark to get a feel for price before ranking. The 980g type has approximately 69.6g of protein per 100g, which is calculated based on the Rich Chocolat flavor. The price per gram of protein is approximately 7.3 yen. On the other hand, ZABAS also has a large capacity type of 2,200g, which can be found in major EC at around 9,880-10,798 yen. Assuming the same nutritional composition, the total protein content in 2,200g is about 1,532g, and the price per gram of protein is calculated to be about 6.5-7.0 yen. 980g is a standard volume that many people can easily get a feel for the price, and 2,200g can be seen as a reference value for continued ZABAS purchases. The 2,200g is the standard volume that many people can easily afford. By placing these two criteria, it becomes easier to understand the cosmetic value of the top large-volume WPC products.

Zabas is a product that is easy to get a feel for the price of a standard product when viewed at 980g. On the other hand, there is also a large 2,200 g type, so it is too early to assume that Zabas itself is overpriced; putting the two criteria together makes it easier to see how low the unit price per protein is for the top large-volume WPC products.
