How to Choose Protein Powder
Check Protein Content
Look for 20-30g protein per serving. Under 20g is under-dosed. Over 30g is likely filler.
Read the Ingredients
Avoid artificial sweeteners if possible. Look for stevia or monk fruit. Avoid gums and fillers.
Calculate Cost per Gram
Divide price by total grams of protein. Under $0.04/g is excellent. $0.04-0.06/g is good.
Third-Party Testing
Look for NSF Certified for Sport or Informed Sport labels to ensure label accuracy.

FAQ
What is the best protein powder in 2026?
Transparent Labs Whey Protein Isolate ($59) is the best overall protein powder. It contains 28g protein per serving, is naturally sweetened with stevia, has no artificial ingredients, and is third-party tested. For budget, Nutricost Whey ($35) offers 25g protein at a lower price. For plant-based, Transparent Labs Plant Protein ($55) is the top pick.
How much protein do I need to build muscle?
To build muscle, consume 0.8-1.0 grams of protein per pound of body weight daily. For a 180 lb person, that is 144-180g protein per day. Protein powder supplements help you reach this target but should not replace whole food protein sources like chicken, beef, eggs, and fish.
Whey isolate vs concentrate: which is better?
Whey isolate is filtered to remove more lactose and fat, resulting in 90%+ protein content vs 80% for concentrate. Isolate is better for lactose-sensitive individuals and those cutting calories. Concentrate is cheaper and retains more beneficial subfractions. For most people, concentrate is sufficient and better value.
When should I drink protein powder?
Drink protein powder within 30-60 minutes after training for optimal muscle protein synthesis. You can also use it as a meal replacement or snack between meals. Total daily protein intake matters more than timing — aim for 20-40g per meal spread across 4-5 meals.
Is plant-based protein as good as whey?
Plant-based protein can be as effective as whey for muscle building when it contains a complete amino acid profile. Look for blends of pea and rice protein, which together provide all essential amino acids. Transparent Labs Plant Protein and Vega Sport are excellent options with 20-25g protein per serving.
