Food first. Powder when the math does not work.
Protein powder is not magic and not a scam. It is a convenience with a real use case.
The honest case for it
Anyone doing strength work wants roughly 1.2 to 1.6 grams of protein per kilogram of body weight a day, and older adults need the high end because aging muscle responds less to each meal. Most people can eat that. Some cannot: small appetites, vegetarian plates, busy mornings. That gap is the entire, legitimate market for protein powder.
Whey or plant, flavored or not
Whey is the best studied and cheapest per gram; a pea and rice blend does the same job for anyone avoiding dairy. Unflavored powder disappears into oatmeal, yogurt and soups, which beats drinking sweet shakes you will tire of. Skip anything sold with proprietary blends or amino acid halo claims; protein content per scoop is the whole spec sheet.
What it will not do
It will not burn fat, build muscle without training, or detox anything. A scoop is simply 25 grams of protein that did not require cooking. Judged as that, it earns its shelf space; judged as a supplement with powers, it disappoints.
Check your real number first
Run your weight through the protein guide in the library. If your meals already reach the target, save the money. If they fall short by a scoop a day, now you know exactly what the powder is for.
Not magic, just convenient
Useful when your plan calls for more protein than your meals reach, especially for older adults protecting muscle. Whey or a plant blend both work; unflavored mixes into anything.
