Protein powder is one of the most-used supplements for a reason — it's convenient, effective, and well-studied. But with hundreds of options on the market, choosing the right one is overwhelming. We've done the research so you don't have to.
What to Look For in a Protein Powder
Before buying, consider:
- Protein per serving — aim for 20–30g
- Leucine content — drives muscle protein synthesis
- Ingredients — avoid excessive fillers and artificial sweeteners
- Taste and mixability — you have to actually drink it
- Price per serving — calculate cost per gram of protein
Top Picks for 2025
Best Overall: Optimum Nutrition Gold Standard Whey
The gold standard for a reason. With 24g of protein, excellent mixability, and a proven track record, this is the safest bet for most people.

Types of Protein Powder Explained
Whey Concentrate
The most common and affordable form. Contains some lactose and fat. Great for post-workout.
Whey Isolate
Further filtered to remove most lactose and fat. Higher protein percentage per serving. Better for lactose-sensitive individuals.
Casein
Digests slowly — ideal for a nighttime protein source to fuel overnight muscle repair.
Plant-Based
Pea, rice, hemp blends for those avoiding dairy. Look for blended plant proteins for a complete amino acid profile.
How Much Protein Do You Actually Need?
Research suggests 0.7–1g of protein per pound of bodyweight is optimal for muscle building. For a 160-pound person, that's 112–160g of protein per day.
Protein powder should supplement your diet, not replace whole food sources. Prioritize chicken, eggs, fish, beef, and legumes.
When to Take Protein Powder
- Post-workout — within 1–2 hours after training
- Morning — if your breakfast is low in protein
- Between meals — to hit daily targets
Common Mistakes
- Relying only on powder — real food protein sources are more satiating
- Taking too much — more than 40g in one sitting provides diminishing returns
- Ignoring total daily intake — the timing matters less than the total
Conclusion
For most people, a quality whey concentrate like Optimum Nutrition Gold Standard is all you need. If budget is a concern, MyProtein delivers excellent quality at a lower price point. Focus on consistently hitting your daily protein goals, and the source matters less than you think.

Frequently asked
Questions people ask about this
How much protein per day do I need to build muscle?
Research suggests 0.7–1.0 g of protein per pound of bodyweight daily for building muscle. For a 160-pound person, that's 112–160 g — ideally spread across 3–4 meals throughout the day rather than consumed in a single large dose.
When is the best time to take protein powder?
Post-workout (within 1–2 hours of training) is a popular choice because muscles are primed to absorb amino acids, but total daily protein intake matters far more than timing. Any meal that falls short of 20–30 g of protein is a good time to add a shake.
Is whey isolate better than whey concentrate?
Only if you're lactose-sensitive or want the leanest possible macros. Isolate is further filtered to remove most lactose and fat, giving a higher protein percentage per serving — but concentrate is cheaper and equally effective for muscle building in most users.
Can I take too much protein powder?
The main risk is diminishing returns, not harm. More than roughly 40 g in one sitting provides limited extra muscle-protein-synthesis benefit. Spread your intake across meals rather than loading a single large shake.
Are plant-based protein powders as effective as whey?
They can be, but choose carefully. Single-source plant proteins like pea or rice alone are incomplete in certain essential amino acids. Look for blended plant proteins — typically pea + rice + hemp — which together provide a complete amino acid profile comparable to whey.
Do I really need protein powder?
No. Protein powder is a convenience, not a requirement — whole-food sources like chicken, eggs, fish, beef, and legumes are more satiating and nutrient-dense. Powder is most useful when your diet falls short of daily targets or you need a quick post-workout option.
