Since I care about how my stomach feels after drinking protein, I pay attention to digestibility. Hydrolyzed whey protein isolate is often a better choice for people like me who want something light and easy on the stomach. If I know I’m sensitive to dairy, I make sure the label confirms low lactose content.
Price vs. Value
I don’t always choose the cheapest option. Instead, I look at the cost per serving and the overall quality. Sometimes a more expensive product is worth it if it has better ingredients, better taste, and better digestion. I try to balance my budget with what actually works for me.
