This is a survey of around 40 popular protein brands in India. 

The results are very surprising. Here are a few observations:

1. Almost all flavored proteins have chemicals like xantham gum (INS 415), anti-caking agents, anti-foaming agents. So try to go with unflavored protein if possible.
2. The only flavored protein that is relatively cleaner is MyProtein, which does not have INS 415.
3. NakPro turns out to have the highest protein content at good price according to the survey.
4. Whey Isolate is costlier than Whey Hydrolyzed in some brands while cheaper in others. Not sure why.
5. Some of the most popular brands turned out to have the worst quality and highest price (per gram of protein).
6. Brands are using different scoop sizes, servings per container, protein per scoop, etc which becomes very confusing for consumers.

Tip: The spreadsheet can be sorted by the "quality of protein" column so that you can see the highest quality proteins at the top. (Click on the small triangle near the column title)

Note: The pricing and other product details keep changing, but the above data gives you a broad idea of the landscape.
