Question 1

What is whey protein powder and what does it do?

Accepted Answer

Whey protein powder is a fast-absorbing protein made from the liquid left during cheese production from cow's milk. It supplies all nine essential amino acids, which may support muscle repair and growth after exercise. Active adults often use it to help meet daily protein targets that food alone may not cover. It is a supplement, not a meal replacement.

Question 2

Is whey protein powder vegetarian or non-vegetarian?

Accepted Answer

Whey protein is lacto-vegetarian because it comes from cow's milk, so most vegetarians in India can use it. It is not vegan and is unsuitable for anyone with a milk allergy. People with lactose intolerance may find whey isolate easier to digest than concentrate, as isolate contains less lactose. Check the label for added milk solids if you are sensitive.

Question 3

Is it safe to take whey protein every day?

Accepted Answer

Daily whey protein is generally considered safe for healthy adults when total protein stays within sensible limits. People with existing kidney disease, liver disease or a milk allergy should be cautious and seek medical advice first. ICMR-NIN recommends meeting protein needs through everyday foods where possible, using supplements only to fill genuine gaps rather than as a routine replacement for balanced meals.

Question 4

Does whey protein cause hair loss?

Accepted Answer

Current evidence does not establish that whey protein directly causes hair loss. Some concern comes from creatine or added ingredients in certain blends, not from whey itself. Hair loss is usually linked to genetics, stress, thyroid issues or nutrient gaps, and these symptoms are non-specific with many possible causes. If hair thinning continues, a doctor can help identify the actual reason.

Question 5

Does whey protein damage the kidneys?

Accepted Answer

Current evidence has not shown whey protein to impair kidney function in healthy individuals at sensible intakes. The concern mainly applies to people who already have kidney disease, who should follow medical guidance on protein. For healthy adults, staying within reasonable daily protein and drinking enough water is prudent. Very high intakes over long periods have not been well studied.

Question 6

Whey isolate vs whey concentrate: which is better?

Accepted Answer

Whey isolate is more processed, so it holds more protein per scoop and less lactose and fat, while concentrate is cheaper and keeps more natural milk nutrients. For lactose sensitivity or a higher protein percentage, isolate may suit you better; otherwise concentrate works well. Check Unbox Health's lab-tested data to verify whether the declared isolate or protein content matches the actual tested amount.

Question 7

How much whey protein should I take per day?

Accepted Answer

Most adults use one to two scoops daily, but this depends on your total protein target. ICMR-NIN recommends about 0.83g of protein per kg of body weight for sedentary adults, while active individuals may need 1.2 to 2.0g per kg. Count protein from food first, then use whey only to cover the remaining gap rather than exceeding your needs.

Question 8

When is the best time to take whey protein?

Accepted Answer

There is no single required time, as total daily protein matters more than timing. Many people take whey after workouts because it absorbs quickly, and it can also be used between meals to reach a daily target. Taking it with or after food may ease digestion for some. Consistency across the day matters more than any single anabolic window.

Question 9

How do I know if my whey protein is real and not fake?

Accepted Answer

Check for FSSAI licensing, a batch number, manufacturing details and an intact seal, and buy from trusted sellers. These steps lower the risk of counterfeits but cannot confirm the actual protein inside. Studies suggest many protein supplements in India are mislabelled, some delivering far less than claimed. Unbox Health independently lab-tests whey products to verify whether declared protein levels match actual tested content.

Question 10

How do I choose the best whey protein powder in India?

Accepted Answer

Compare products on real protein per serving, amino acid quality, added fillers and third-party testing rather than only price or flavour. Watch for amino spiking, where cheap ingredients like glycine inflate the protein figure on the label. Use Unbox Health's independent lab-tested ratings to compare which brands actually deliver the protein content and label accuracy they claim.
