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".

Doesn't seem to include Costco Isopure, which is $60 for 3.5lbs, sometimes found on sale for $50. It's my goto because it has nothing except protein.

Or skip the middlemen and buy whey protein isolate directly from a dairy/creamery, in bulk: https://old.reddit.com/r/Supplements/comments/16r3xjt/psa_i_...

I wonder if there are similar upstream sources for soy, pea, or rice protein isolate?

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.

Doesn't include Form protein (https://formnutrition.com/), which has the added benefit of not coming in a plastic container.

It would be great if standard form for sites like this would be for people to give their email address in order to be updated as new features are added. I would love to know when Canada is added but am afraid that without signing up for updates, this will slip from my memory before the day is done. I shudder to think how many sites this has happened to me already - where features have since been added that would make the site applicable to me but I’ll never know because I couldn’t sign up for updates!

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.

Nice. I hadn't heard of iHerb before. Would be great to include myprotein (tricky with "discount" codes) or one of the expired protein powder sources (e.g. supplementhunt).

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

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

it would be nice to see all the ingredients and see which ones have poor/toxic additives
