Questions about whey protein

Answered with the data on this page

Which whey protein should you buy?
HSN Raw Series 100% Whey protein concentrate 2Kg from HSN, with 80 points out of 100 at €30.00/kg. The mark is 35 % price against the cheapest in the category, 35 % verifiable quality (certification, purity and additives), 20 % the category's own requirements and 10 % the buyers' rating at the store, and no commercial deal moves the ranking.
Which is the cheapest whey protein?
HSN Sport Series Evobasic whey 2Kg from HSN, at €20.00/kg (2000 g pack for 39,99 €). It sits at verification level 1 out of 4. Cheap is not the same as well scored: price is 35 % of the mark and most of the rest is how verifiable its certification is.
How much does a kilo of whey protein cost?
Between €20.00/kg and €89.32/kg across the 17 stores compared, with a median of €45.14/kg. That is the price per kg, not per pack: two tubs at the same price can cost twice as much as each other depending on what is inside.
What certification should whey protein have?
Of the 251 products compared, 1 reach level 4 (the certification is backed by a third party: either we checked it with the body that issues it, or the product carries in its name a trademark that requires a third party behind it, such as Creapure or IFOS) and 4 reach level 3 (a lab report published by the brand itself). The remaining 246 stop at a certification claimed on the product page, or none at all. Only level 4 is checked against whoever issues the certification.
How much whey protein should you take a day?
The reference dose this site uses for whey protein is 20 g - 40 g a day, with strong evidence. Source: Jager R et al. ISSN position stand: protein and exercise. J Int Soc Sports Nutr. 2017;14:20. Dosis de 20-40 g de proteina por toma para maximizar la sintesis proteica muscular.. That is the dose of the ingredient in the study cited, not a recommendation for you nor a claim about any product in the table.
