I sure hope so! I use Optimum Nutrition Gold Standard whey protein. I have no affiliation with the brand but it's easy to find, tastes awesome, and it's not hard to find on sale (at least here in the US). I look for whey ISOLATE which should be very low in carbs and void of soy protein (many sources say men should avoid large quantities of soy protein)
Casein protein powder can be especially beneficial because it's often much lower in carbs than milk is, yet it still digests very slow (perfect for drinking just before bed).
Either way, I say it all the time on this forum and I'll say it again: supplements are ultimately a waste of money for most people. Many people make the mistake of assuming supplements will help them achieve their fitness/health goals quicker, but that's not always true.
Supplements fill in the gaps to an imperfect diet, but if there aren't any gaps (deficiencies) you're just wasting your money. Again, I do use protein powders and some basic supplements, but I spend very little money on them.
