Protein Powder

I'm a 31-year-old woman in the USA who strength trains 4 times a week and works a full-time desk job, looking for the best protein powder. What would you recommend?

For your routine — strength training four times a week and spending much of the workday at a desk — I’d prioritize a protein powder that helps you build and maintain muscle, is easy to use consistently, tastes good enough to enjoy daily, and doesn’t cost a fortune.

My recommendation: start with a high-quality whey protein isolate if you tolerate dairy. You generally don’t need a special “women’s protein,” a collagen blend, or an expensive formula with lots of extra ingredients.

What I’d look for in a protein powder

25–30 g of protein per serving

A convenient amount for supporting muscle recovery and growth after strength training.

A complete protein source

Whey, casein, soy, or a well-formulated plant blend can all work. Whey is especially convenient because it provides all essential amino acids.

Good digestion and independently tested quality

Choose a product with clear ingredient labeling and, ideally, NSF Certified for Sport, Informed Sport, or another credible independent testing program.

A reasonable price per serving

You’re paying for useful protein, not a long list of added ingredients or flashy marketing.

My top protein powder picks

These are the options I’d shortlist for someone who lifts regularly and wants a practical everyday supplement. Current expert reviews also highlight Transparent Labs and Optimum Nutrition as strong choices.

Best overall

Transparent Labs Grass-Fed Whey Protein Isolate

Whey isolate · Premium

About 28 g protein per serving

Low in carbs and fat, with no added sugar in the reviewed chocolate formula

Independently certified, with a relatively transparent ingredient list

Why I’d choose it: A great starting point if muscle-building support and ingredient transparency are your priorities.

Trade-off: relatively expensive, at roughly $2 or more per serving.

Best everyday value

Optimum Nutrition Gold Standard 100% Whey

Whey blend · Everyday use

Around 24 g protein per serving, depending on flavor

Widely available with plenty of flavor options

A blend of whey protein isolate, concentrate, and hydrolyzed whey

Why I’d choose it: You get plenty of protein without paying a premium for a pure isolate. It's a sensible choice for daily shakes after lifting or alongside breakfast.

Trade-off: contains some lactose, so it may not suit sensitive stomachs.

Momentous 100% Plant Protein Powder

Plant-based · Dairy-free

A vegan-friendly alternative

Designed to provide protein for training and recovery

Worth considering if you avoid dairy or prefer plant-based foods

Why I’d choose it: It lets you keep a consistent protein routine without whey. Check the current label for protein per serving and certification before buying.

How much protein should you aim for?

The powder matters less than your total daily protein intake.

For adults who strength train regularly, a useful target is approximately 1.4–2.0 grams of protein per kilogram of body weight per day, depending on training demands and goals.

Here’s what that looks like:

Body weight | Daily protein target |

120 lb (54 kg) | 76–109 g |

140 lb (64 kg) | 90–128 g |

160 lb (73 kg) | 102–146 g |

180 lb (82 kg) | 115–164 g |

You don't need to get all of this from supplements. Aim to spread protein across meals, with roughly 25–35 g at each main meal as a practical starting point.

For your desk job: A shake can be particularly useful as a quick afternoon snack or an easy breakfast addition on busy days. You don't need to drink it immediately after your workout; your overall daily intake is more important than a narrow post-workout window.

Let’s narrow it down to the best one for you

I can make a more specific recommendation if I know a little more about your goals and preferences.
