What to Look For
- Isolate vs. concentrate: Whey isolate is processed to remove most fat and lactose, giving higher protein per scoop (90%+) and less digestive distress. Concentrate retains more natural co-factors but has slightly less protein per gram.
- Protein per serving: Look for 20–25g protein per scoop as a baseline for post-workout recovery. Check the label for total grams, not just percent daily value.
- Certifications: Third-party tested products (NSF Certified for Sport, Informed Sport) confirm what the label claims and are free from banned substances — important if you compete.
Frequently Asked Questions
What is the difference between whey isolate and concentrate?
Whey isolate undergoes additional filtration to remove most lactose and fat, resulting in 90%+ protein by weight and faster absorption. Whey concentrate is less processed, contains 70–80% protein, and retains more naturally occurring growth factors. Isolate is the better choice if you have lactose sensitivity.
How much protein do I actually need per day?
The research-backed range for active people is 0.7–1g of protein per pound of bodyweight per day. Most people eating a balanced diet get enough from food; protein powder is most useful for hitting targets around training or on busy days.
Can I take whey if I am lactose intolerant?
Whey isolate is a good option for people with mild lactose intolerance, since most of the lactose is removed during processing. If you have a true dairy allergy, avoid all whey products and choose a plant-based alternative instead.
