Question 1

Protein powder — the short answer

Accepted Answer

Whey protein is the most common and most-researched type of protein powder, and the best choice for most people who train. A typical serving is 20-30 grams of protein, and total daily intake matters more than exact timing. Trainees need 1.6-2.2 grams of protein per kilogram of body weight per day, and protein powder simply fills the gap left by food. To compare products, the right metric is how much protein there is per 100 grams of powder — not the price per package or the flavor.

Question 2

What is protein powder and why do you need it?

Accepted Answer

Protein powder is a concentrated protein supplement used to support muscle building, tissue repair, and immune function. Active individuals need 1.6-2.2g protein per kg of body weight, which is hard to achieve from food alone. Protein powder offers a convenient, cost-effective way to close this gap, especially post-workout.

Question 3

What are the different types of protein powder?

Accepted Answer

There are a few main types of protein powder, and the difference between them is mainly protein percentage, absorption speed, and price. Whey Concentrate (WPC) — 70-80% protein, fast-absorbing and tasty; the most common and most cost-effective type, suitable for most people who train. Whey Isolate (WPI) — extra-filtered to 90%+ protein with less lactose and fat; suited to the lactose-sensitive and to cutting. Hydrolysate — whey that is partially pre-broken-down for faster absorption; the most expensive type, and its advantage over isolate is small for most people. Casein — slow-digesting milk protein over hours, nicknamed the 'night protein' since it is taken before bed for sustained release. Plant-based — pea, soy, or rice; suited to vegans and the lactose-sensitive, and a good blend provides a complete amino acid profile. For most trainees, concentrate or a concentrate-isolate blend is the sensible choice.

Question 4

How do you choose a protein powder?

Accepted Answer

Choose based on your goal (muscle building: whey concentrate/isolate; weight loss: isolate; overnight recovery: casein), lactose tolerance (isolate or plant-based if sensitive), and budget (concentrate is most cost-effective). Look for products with protein as the first ingredient, at least 20-25g per serving, and minimal added sugars.

Question 5

When is the best time to take protein powder?

Accepted Answer

The most important window is 30-60 minutes post-workout for optimal muscle recovery with fast-absorbing whey. Other useful times: morning to break the overnight fast, before bed with casein for sustained release, and between meals as a high-protein snack. Spreading protein across 3-4 servings throughout the day matters more than exact timing.

Question 6

How much protein should you consume daily?

Accepted Answer

Recommendations vary by activity: sedentary adults need 0.8g/kg, strength trainers 1.6-2.2g/kg, and those dieting with exercise up to 2.4g/kg to preserve muscle. For example, an 80kg lifter needs 128-176g daily — if food covers 100g, one or two protein shakes fill the gap. Exceeding 2.4g/kg has not been shown to provide additional benefit.

Question 7

Are there side effects of protein powder?

Accepted Answer

For most healthy people, protein powder is safe for daily use. The most common side effects are lactose-related (bloating, gas) — easily solved by switching to isolate or plant-based protein. Very high intake (above 3g/kg long-term) may stress kidneys in people with pre-existing kidney issues, but research consistently shows high protein intake is safe for healthy kidneys. Stay well hydrated and maintain a varied diet.

Question 8

What is the difference between isolate and concentrate?

Accepted Answer

The main difference is the level of filtration: concentrate (WPC) contains 70-80% protein with slightly more lactose and fat, while isolate (WPI) is extra-filtered to 90%+ protein with less lactose. For building muscle both work the same — the difference matters mainly for those sensitive to lactose or counting calories. Concentrate is cheaper and enough for most people; isolate is worth the extra if you have lactose sensitivity or are cutting.

Question 9

How many scoops per day?

Accepted Answer

There is no fixed number — it depends on how much protein you are missing from food. A typical scoop provides 20-30 grams of protein, and most trainees use one to two scoops a day to complete the daily target of 1.6-2.2 grams of protein per kg. The simple rule: calculate how much protein you get from regular meals and how much is left to the target — that decides how many scoops. There is no benefit to piling on more; protein beyond what the body uses is simply burned for energy.

Question 10

Does protein powder make you gain fat?

Accepted Answer

Protein powder by itself does not make you gain fat. Fat gain comes from a total daily calorie surplus, not from any specific protein. A typical serving contains only about 100-130 calories, and protein actually increases satiety. If you add shakes on top of a full diet without watching calories, you can of course gain weight — but that is true of any food. Used correctly, protein powder is a tool that helps preserve muscle mass even while dieting for weight loss.

Question 11

What is the best recommended protein powder?

Accepted Answer

It depends on your needs. For most people: Super Effect whey protein (chocolate flavor) offers an isolate/concentrate blend with 25.8g protein per serving, made in Israel, great taste, and fair price. For premium brands: Ronnie Coleman Signature Series delivers rich flavors. For variety: MusclePharm COMBAT is solid for fast post-workout absorption.
