Frequently Asked Questions
-
Whey protein comes from milk during the cheese-making process. It’s considered a complete protein because it contains all nine essential amino acids.
-
The ‘best’ type of whey protein powder depends on your goals and budget. Here are the differences between each type:
- Whey Concentrate: Least filtered. Around 70–80% protein, with some natural carbs and fats. Tasty, affordable, and a good all-rounder.
- Whey Isolate: More filtered. About 90% protein and very low in lactose or fat. Perfect if you want premium protein with minimal extras. Digestive friendly for lactose sensitive individuals.
- Whey Hydrolysate: Similar to the premium quality of whey isolate, but is also pre-broken down so your body absorbs it super quickly. Great for recovery and gentle on digestion. -
The easiest option is to mix the whey protein powder with water, milk, or a milk alternative to make a protein shake. You can also blend it into smoothies, stir it into oatmeal or yogurt, or add it to pancakes and baked goods. Heat has very little effect on whey’s nutritional value, so baking with it is perfectly safe and still delivers a high-quality protein boost.
-
Yes, when used as part of a balanced diet, whey protein can be a convenient and safe way to increase protein intake. Whey protein powder supports muscle growth and recovery, can help with weight management by promoting fullness, and may even benefit immune health and blood sugar control. Some people who are sensitive to lactose may prefer whey isolate or hydrolyzed whey, which are easier to digest.
-
The fast-digesting nature of whey protein means it is commonly used after exercise to assist with muscle building and recovery, however, it is safe and effective to be consumed any time of day to help meet your daily protein requirements.
-
Yes, whey protein is safe to consume daily for most healthy adults. It is a high-quality, complete protein that supports muscle growth, recovery, and overall nutrition. When taken in moderation and as part of a balanced diet, daily whey protein can help meet your protein needs without harmful effects. However, those with kidney issues, or other medical conditions should consult a healthcare professional before using whey protein regularly.
-
Whey protein is safe for most people, but there are some cases where it should be limited or avoided. People with kidney or liver disease may need to restrict protein intake because high amounts can place extra strain on these organs. Those with severe lactose intolerance might experience digestive discomfort from whey concentrate, though whey isolate or plant-based proteins are often better tolerated. Individuals with milk allergies should avoid whey protein altogether since it is derived from dairy. In addition, anyone on a medically restricted diet or with specific health conditions should consult a healthcare professional before adding whey protein to their routine.
-
The amount of whey protein you need each day depends on your goals. For general health, a single serve of around 20-25 grams can help cover any gaps in your diet. If your goal is muscle growth and recovery, 1–2 servings (20–50 grams) per day is typically recommended. Whey protein is a lean protein source, so for weight loss, 1-2 servings (20-50 grams) can help reduce appetite and preserve lean muscle while cutting calories. Athletes or those training intensely may benefit more from 2 servings per day (40 grams or more), depending on their total daily protein requirements. Whey protein should always supplement a balanced diet rather than replace whole food sources.
-
Pure whey protein is naturally gluten free because it comes from milk. However, not all whey protein powders are guaranteed to be gluten free, as some flavored or blended products may contain additives, thickeners, or ingredients with gluten. If you have celiac disease or gluten sensitivity, it’s important to choose a whey protein that is clearly labeled “gluten free” to ensure safety.
