When choosing a product, are there other parameters to consider than protein per dollar? Are there any interesting metrics for "quality"? I'd assume it's not just "protein is protein". Would be interesting to see other metrics deployed, and the ability to find my own "sweet spot".

100%, we have collect some nutrition data that we don't expose yet e.g. cholesterol, added sugar, trans fat etc. Sort of optimised for not having the table _extremely_ wide. But might be an option adding in some extra, as well as adding filter options for that to allow you to tweak it and find your sweet spot.

Optimally we'd have even more information re: amino acids etc, but that information is _hard_ to parse out

Now this is awesome. Hope iHerb appreciates this as it should will lead to more sales through them. Scraping is always tricky.

Love that you’ve included other nutritional facts. Would be cool to also incorporate review scores and/or taste somehow, however subjective.

Really nice work.

Looking over this list it seems like this is mainly for bulking protein (sold in larger volumes).

Taste is a big factor, as well as how it makes you feel. Some brands "go down" better than others. How the protein is made/filtered/etc can also have an impact on the quality of what you get.

Then of course there is flavorings etc.

In general, I've heard it said that if "lifestyle" protein is what you are looking for, you're gonna shop for quality not for quantity.

If you are bulking and you need 250g+ protein per day... then you buy what fits your budget and you can hold down. ;)

I'm surprised to see some difference in the result for "Plant based" and "vegan"

I guess there could be cases where a product is plant based, but still contains some animal products. But I'll double check the matching to see if anything looks weird. Also, feel free to provide an example here or to elina@nutritionprices.com of a badly categorised product and I'll investigate

I've read that some forms of protein (such as from animal sources) are more "bio available" than others, and thus result in a higher net result of protein absorbed.

I see I can filter out specific sources, but it'd be cool if as part of the normalization, that it took this into account in some way.

I think pricing differs by retailer too. Could you do the same thing for different countries (Canada, UK, etc)?

Yes, on the roadmap to add more countries and retailers e.g. Amazon, and other large protein retailers. Any particular countries/retailers you'd like to see first?
