I misunderstood your OP. I thought you were making your own protein shakes from ingredients. I see that you purchase a commercially prepared product instead. The only comment I have about that applies to any commercially prepared product, especially one aimed at the ‘low carb’ and/or ‘keto’ community.
Read the label very carefully, including the list of ingredients and the order they’re listed in. The first 3 or 4 ingredients are generally the main ones. You will be shocked by how often you see one of the many stealth words for sugar. Another thing to watch for is whether or not the total calories of the product matches the total calories of the individual macros listed in the nutrition breakdown. Producers of a product aimed at the low carb market have a lot of incentive to hide as much carbs as they can get away with. If there’s little or no difference, you can ignore it. But if the difference is multiple calories just assume they’re hidden carb calories and add to the carb total. That’s the only way to avoid consuming a lot of hidden carbs.
