SupplementsThe most popular supplement in every gym bag. Here's what it does, and whether you're actually one of the people who needs it.
A byproduct of cheese-making, whey is a fast-digesting milk protein containing all essential amino acids โ essentially a convenient, concentrated way to hit a daily protein target without cooking or measuring out whole foods.
People struggling to hit protein targets through meals alone โ busy schedules, limited appetite, or a mostly vegetarian diet where protein-dense whole foods take more planning. It's a convenience tool, not a requirement.
Anyone already comfortably hitting their protein target through dal, paneer, eggs, curd, or chicken. An extra scoop on top of an already-sufficient diet is just additional calories with no extra muscle-building benefit.
Protein content per scoop (ideally 20-25g), a reasonably short ingredient list, and third-party testing certification if available โ a marker of quality control that's worth prioritizing over flashy marketing claims.
A daily habit for millions, but the evidence on whether they actually do much for most people is more mixed than the marketing suggests.
