Aim for 0.7–1 gram of protein per pound of bodyweight daily — that single number is the clearest answer current science gives you for calculating your protein needs for muscle building. Everything else is fine-tuning. Here’s exactly how to apply it to your body, your diet, and your goals without guesswork or expensive labs.

The Science Behind the Number
nn
A 2022 meta-analysis in the British Journal of Sports Medicine covering 49 studies confirmed that muscle protein synthesis plateaus around 1.62 g per kilogram of bodyweight (roughly 0.73 g/lb) for most resistance-trained individuals. Going higher won’t hurt you — excess protein is simply oxidized for energy — but it won’t build more muscle either. The Mayo Clinic adds that protein quality matters: leucine-rich sources like whey, eggs, and chicken activate muscle-building pathways most efficiently.
nn
Your personal formula: Bodyweight (lbs) × 0.7 = minimum. Bodyweight (lbs) × 1.0 = upper ceiling. Land anywhere in that range and you’re covered. Beginners starting their first 3 months of training can sit closer to 0.7; advanced lifters in a caloric deficit should push toward 1.0.
nn
Spread it out. Consuming protein in 4–5 meals of 30–40 g each maximizes muscle protein synthesis better than eating the same total in one or two sittings. Think of each meal as a separate anabolic trigger.
nn
⚠️ Safety note: If you have kidney disease, a history of kidney stones, or are pregnant, consult your doctor before significantly increasing protein intake. High protein is safe for healthy adults but requires medical clearance for certain conditions.

Top Protein Supplements Compared
nn
nn
#1. Optimum Nutrition Gold Standard Whey — Best Overall for Muscle Building
nn
Gold Standard delivers 24 g of whey protein per scoop — including whey isolate as its first ingredient — making it the benchmark every other protein powder is measured against. It’s third-party tested, mixes clean with no gritty texture, and has been a gym staple for over 20 years for a reason. If you’re new to protein supplements or just want something that works without thinking, this is your answer. The American Council on Exercise consistently recognizes whey isolate as the gold standard for post-workout recovery.

#2. Garden of Life Sport Plant Protein — Best Dairy-Free Option
nn
Garden of Life Sport packs 30 g of protein per serving from a blend of pea, navy bean, lentil, and garbanzo — enough to rival whey when paired with a leucine-rich diet. It’s NSF Certified for Sport, meaning it’s tested for banned substances, which matters if you compete in any tested athletic event. The combination of plant sources creates a complete amino acid profile that single-source plant proteins (like plain pea protein) often miss.
nn
- n
- ✅ 30 g protein per serving — highest in its plant-based category
- ✅ NSF Certified for Sport — verified clean for competitive athletes
- ✅ Added 2 billion CFU probiotics for improved digestion and absorption
- ❌ Slightly thicker texture — some users prefer blending over shaking

Frequently Asked Questions
nn
Can I get enough protein without supplements?
n
Absolutely — a 6 oz chicken breast delivers roughly 53 g of protein on its own. If your daily target is 150 g, three solid whole-food protein sources per day plus Greek yogurt or eggs gets you there without ever opening a tub of powder.
nn
Does protein timing actually matter?
n
Total daily protein matters far more than timing — research shows that hitting your daily target produces the same muscle gains regardless of whether you eat before or after training. That said, spreading intake across 4–5 meals of 30–40 g each is the most practical way to maximize absorption and stay consistent.
nn
Is 1 gram per pound of bodyweight too much?
n
For healthy adults, no — studies show intakes up to 2.4 g/kg (1.1 g/lb) are well-tolerated and safe long-term. If you’re in a caloric deficit or doing high training volume, 1 g/lb actually helps preserve lean muscle while fat is being lost.
nn
Our Pick
nn
Calculate your target using the 0.7–1 g per pound formula, prioritize whole-food sources first, and use a supplement only to close the gap. If you need one, Optimum Nutrition Gold Standard Whey is the most tested, most trusted, and most cost-effective option on the market in 2026 — I’ve recommended it to clients for eight years and the science hasn’t changed that verdict.
