When you browse protein products, all manufactures determine how much protein goes into a serving and how large a serving is. It's completely arbitrary. That makes it impossible to order products by serving price, because we're comparing apples to oranges.
To fix this, we gather all products, together with their nutrition facts, and calculate normalized serving size, where each serving consist of 25 grams of protein. This enables us to compare price and nutrition facts for all products.
We collect our prices from iHerb.com.
Our products are updated once a day.
We filter out out-of-stock items during our daily update. However, if a product goes out of stock during the day, we won't be aware until the next update.
We gather categories and nutrition facts directly from product details and apply post-processing to clean up any inconsistencies. We're constantly tweaking this algorithm. If you notice any errors, please contact us at [email protected].
We don't include shipping and tax as they vary by location. However, iHerb generally offers free shipping for orders over $30 within the U.S.
