Most Protein Powders in India Are Not What the Label Says

The tub says 24 grams of protein per scoop. It cost you three thousand rupees. The question nobody asks at the point of sale is whether there are actually 24 grams in there.

In 2024 a group of Indian researchers decided to check. They bought 36 of the most popular protein supplements sold here, paid for the testing themselves, and published what they found. It is not comfortable reading.

What the testing found

Close to 70% of the products contained less protein than the label claimed. Not marginally less. Two products from a single manufacturer came in 62% and 50.4% below their stated protein content. One widely prescribed brand — the sort handed out in hospitals — was roughly 30% short.

Then the contaminants. Across the sample, lead turned up in around three quarters of products, cadmium in just over a quarter, and aflatoxins — fungal toxins — in about one in seven.

And a third category that concerns me most as a pharmacist: several powders contained herbal extracts that were never the reason you bought a protein supplement. Green tea extract, garcinia cambogia, ashwagandha, curcumin. Added for the label rather than for you, and several with a documented association with liver injury.

A follow-up study published in 2025 looked specifically at whey powders and reported the same pattern — poor quality, and marketing claims the contents did not support.

What the testing actually measured

The scale is worth pausing on. These were not obscure products bought from a back street. They were the supplements most commonly sold and most commonly recommended, including ones dispensed through pharmacies.

Why this happens

Protein content is usually measured by nitrogen. Protein contains nitrogen, so more nitrogen reads as more protein. The trouble is that cheap nitrogen-rich compounds read the same way to the test — the same loophole behind the melamine scandals in dairy years ago. The technique is politely called protein spiking.

The wider reason is regulatory. In India these products sit in the nutraceutical category rather than being regulated as medicines, so nobody is routinely checking whether the tub contains what the printing says. The testing that does happen is largely voluntary, which means it happens most reliably at the companies that least need it.

The liver part, which is the bit I care about

Supplement-induced liver injury is real, rising, and consistently underestimated because people do not think of a health product as a drug. Green tea extract and garcinia cambogia are repeat offenders in that literature, and neither belongs in a protein powder.

This matters more here than in most places. Fatty liver is extremely common in India, often in people who feel entirely well and have never had a drink, and a liver already under strain is not the organ you want to hand an unlabelled herbal load. If that is you, the fix is dietary rather than pharmaceutical, and it does not include a proprietary blend.

If you have been taking a supplement with a herbal blend and feel unusually tired, itchy or nauseated, or you notice dark urine or yellowing of the eyes, stop it and see a doctor. Liver function tests are cheap and already sit in most standard panels.

How much protein you actually need

Worth asking before you buy anything. For building or keeping muscle, the benefit flattens out at roughly 1.6 grams per kilogram of bodyweight per day. For a 65 kg person that is about 105 grams.

Most people reach that with dal, curd, paneer, eggs, soya, milk and fish, and doing it that way costs less per gram of protein than any tub on the shelf. Powder solves a convenience problem, not a nutritional one. If you are vegetarian or vegan and genuinely struggling to hit the number, that is the legitimate case for using one.

What protein actually costs, per gram

The case for a tub is convenience. It is worth seeing what that convenience costs against food you already buy.

Soya chunks are the uncomfortable comparison. They deliver roughly two thirds the protein density of whey at a small fraction of the cost, with no label to distrust.

Where the regulation actually stands

Protein supplements in India sit under the food and nutraceutical rules rather than the drug rules. That distinction decides almost everything about this article.

A medicine must prove its contents, batch by batch, to a regulator that inspects. A nutraceutical carries a label the manufacturer writes. Enforcement is largely complaint-driven and post-market, which means a product is typically investigated after somebody is harmed rather than before it reaches a shelf.

This is not an argument that every tub is dangerous. It is an argument that the label is a marketing document, not a guarantee, and that third-party batch certification is the only thing that converts it into evidence.

If you are going to buy one

• Read the protein per 100 g, not per scoop. Scoop sizes are chosen by the marketing department. Per 100 g lets you compare two tubs honestly, and a decent whey concentrate sits around 75–80 g per 100 g
• Want a short ingredient list. Whey protein concentrate or isolate, a flavouring, a sweetener, perhaps lecithin. That is a complete list
• Treat added herbal extracts as a reason to put it back. Green tea extract, garcinia, fat-burner blends and anything described as proprietary belong in a different aisle
• Look for genuine third-party testing — Informed Choice, NSF Certified for Sport, or a published lab report with a batch number. A gold sticker reading lab tested, with no lab named, is decoration
• Be suspicious of a price that is too good. Whey is a commodity with a floor price. A tub well below it is telling you something about what is inside
• Buy from the brand or an authorised seller. Counterfeits of the popular imported brands are widespread in Indian marketplaces

Reading a label properly

Who is most exposed by this

Not everyone carries equal risk from a contaminated daily powder.

• Anyone with existing liver disease, including the very common fatty liver, where an added herbal load is the last thing the organ needs
• Anyone with reduced kidney function, given the cadmium and lead findings
• Pregnant women, for whom heavy metal exposure carries specific risk
• Children and teenagers, who are often handed the same tub as the adult in the house at a fraction of the bodyweight
• Daily long-term users — a contaminant that is trivial once a month is a different proposition twice a day for three years

Do you need one at all?

Work through this honestly before you spend anything.

• Add up your current protein for two ordinary days. Not a good day. An ordinary one. Most people discover they are 30–50 g short rather than 100 g short
• Ask whether the gap is a food problem or a timing problem. A missing 30 g is usually one meal that was tea and a biscuit
• Try closing it with food for three weeks. Soya chunks, curd, eggs, an extra katori of dal. If you close it, you are done
• If you genuinely cannot — travel, appetite, a vegan diet with a high requirement — then buy one, and buy it on certification rather than flavour

I have no objection to protein powder. I object to it being the first purchase rather than the last resort, because that sequence is how people end up paying a premium for lead.

What I will not tell you

That protein powder is dangerous. Clean whey is one of the better-studied and better-tolerated things you can buy. The problem is not whey. The problem is not knowing which tub contains it.

That you need one. Almost nobody does. It is a convenience, and it is priced as one.

That expensive means clean. The testing found short-weighted protein across price points, including brands sold through pharmacies and recommended by clinicians.

A note on what I actually recommend

Clients ask me to name a brand. I will not, for the reason this whole article exists: the testing found problems across price points and reputations, and a recommendation I made today could be a different formulation by the next batch. What travels better than a brand name is the checklist — protein per 100 g, short ingredient list, no herbal blend, named third-party certification with a batch number. Apply that and the shelf narrows very quickly on its own.

The short version

• Independent testing of 36 popular Indian protein supplements found close to 70% contained less protein than claimed, some by more than half
• Lead, cadmium and aflatoxins appeared across a large share of the sample
• Several powders carried herbal extracts with a documented link to liver injury, added for marketing rather than nutrition
• Nitrogen-based testing allows protein spiking, and the nutraceutical category is barely policed
• Protein benefit plateaus near 1.6 g per kg of bodyweight, and food gets most people there more cheaply
• If you do buy: protein per 100 g, a short ingredient list, no herbal blends, real third-party certification

Before you act on any of this

I am a pharmacist and a nutritionist. I am not your doctor, and this article is general information rather than advice about you specifically. If you have liver or kidney disease, are pregnant, or take regular medication, check before adding any supplement — herbal ingredients interact more often than people expect. Nothing here is a reason to start, stop or change a prescribed medicine. What this article can do is tell you which questions are worth asking at your next appointment.
