Our "Protein Project" report is here

What is it?
Unique public-health project funded by @paraschopra to analyze common/well-known protein supplements sold in India

Who did it?
Me & team at The Liver Institute with world class, independent food/drugs testing Neogen Labs. Image
2/30 What did we analyze?

36 brands
- pure whey, whey-blend, whey & herbal blend, plant based and vegan types
- national, multinational and local brands
- all bought from authorized sellers or brand website
- none were spurious, authenticity of products checked✔️
3/30 Which brands did we analyze?

Here they are, all 36 of them

All received with packing and seal intact

Opening the seal and pack removal for analysis was done by the lab personnel at the main lab before analysis and for sterile/safe storage for analysis repetitions Image
4/30 What analysis did we perform on these protein products?

Analysis of protein % (Kjeldahl method)
Detection of fungal toxins/aflatoxins (HPLC)
Pesticide (GC & LC MSMS)
Heavy metals (ICP-MS)
Complete GC-MSMS profiling
Synthetic, anabolic steroids (GC-MS HP5 column)
5/30 Results - I

Protein content/protein %

..which could cause liver injury without additional data on safety.

The full list of protein supplements, their brands and labelled and detected protein percentages are given below. Image
11/30 Results - I (end)

In this figure, we have shown how severe the mislabeling on the protein products is, with respect to protein content advertised on the bottle/package vs what is actually discovered on analysis. The gradient shows least to worst protein percent mislabeling Image
12/30 Results - II

Fungal toxins & Pesticide detection

Aflatoxin is a toxin produced by the fungus Aspergillus flavus, which can infect crops at pre- and post-harvest stages and negatively impact food quality. Exposure to aflatoxin can lead to reduced growth in children.. Image
13/30 Results - II (cont)

liver damage, and liver cancer. Per guidelines, the limit of aflatoxin exposure in processed food such as cereals in humans is 10 ppb (parts per billion). We identified five out of 36 protein products with aflatoxin contamination. These included..
14/30 Results - II (cont)

Ultra-soy protein by Forever Life (product code 10), Whey isolate by Optimum nutrition (code 15), B-protin by British Biologicals (code 17), Protein powder by Elements (code 30), and Nutrilite plant protein by Amway (code 36). Of these..
15/30 Results - II (cont)

the last two brands, Protein powder by Elements & Nutrilite plant protein by Amway, had aflatoxin above safe limits. Aflatoxin detection and corresponding product codes are shown below. For product code, please refer to tweet 3 or descriptions above. Image
16/30 Results - II (cont)

Concerning pesticide detection, three out of 36 samples were contaminated by a trace amount of pesticide. Vegan Protein by Big Muscles contained Fenobucarb at 0.061 mg/kg; Protein & Herbs by Oziva contained Azoxystrobin at 0.033 mg/kg AND..
17/30 Results - II (end)

..Dimethomorph at 0.013 mg/kg & Weight Plus Protein by Dr. Vaidya’s contained Thiamethoxam at 0.017 mg/kg. Only among protein brands that were purely plant/vegan was pesticide residue identified, & none were noted in pure whey or blended whey products. Image
18/30 Results - III

Heavy metal detection

In all 36 samples, Mercury and Thallium were not detected. Five samples contained trace levels of Arsenic. These included Ultra-soy protein by Forever Life; Protinex by Danone; My first protein by Healthkart; Protein powder..
19/30 Results - III (cont)

..by Vestige, and Protein Plus by Bakson’s Homeopathy. Ten products also had traces of Cadmium (very low levels). Most samples contained Lead at low levels, and Copper was found in all the samples at different levels, with the highest in..
20/30 Results - III (cont)

..Ultra-soy protein by Forever Life.

Complete results of heavy metal detection is below. I would be cautious about any amount of Lead in products as there is no safe level of Lead. Even high levels of Copper isnt ideal as it is toxic to brain/liver. Image
21/30 Results - III (end)

Companies may argue that Lead detected was within range as per regional rules, but fact is Lead has no safe limit of exposure. Also, notable is that there were brands WITHOUT any detectable Lead or metal for that matter showing good production quality. Image
22/30 An introduction to final summary

Our final summary on best brands took into consideration all relative analysis outcomes, from protein content, mislabeling, heavy metal detection and contaminants. This is a personal opinion of the group and is in no way a recommendation.
23/30 FINAL SUMMARY
Best whey protein- One Science & Ultimate Nutrition
Best medium range whey- Nutrabox
Best Vegan protein- Origin
Best herbal whey- Himalaya[CAUTION]
Worst whey brand- Big Muscles
Worst plant-based- Amway
Worst brands advertised as best- Protinex/Ensure/B-protin
24/30 FINAL SUMMARY (cont)

Worst protein content- B-Protin, Ensure Plus, Bakson's Protein & Vegan by Big Muscles

Brands that need EXTREME caution- Protein by Elements/Nutrilite by Amway [fungal toxins]

Herbal blended proteins have MORE CONTAMINANTS/Pesticides than non-herbal.
25/30 FINAL SUMMARY (cont)

Only vegan/plant-based supplements had pesticide residue - none of pure whey or whey-blends had this issue
[Origin is the best in vegan category, is super clean]

Brands to be used WITH CAUTION
- Himalayan Organics/Patanjali/Himalaya/Herbalife/Oziva...
26/30 FINAL SUMMARY (cont)

...because they contained at least one or more known and documented liver toxic agent such as
green tea/curcumin/turmeric/ Ashwagandha/Garcinia extracts.

STAY AWAY FROM THESE - herbal+dietary supplements are a major cause of liver failure in the West. Image
27/30 Details of purchased products along with ingredient details is available at this link for download
file.io/N8gds52IDmSL

You may use it to find the safest protein for your use, after consulting with your doctor.
28/30

PS: We DID NOT detect significant steroids- synthetic/anabolic in any products analyzed.

Detailed analysis on full scan and trace level detection of steroids -synthetic or plant-based will be provided as supplementary data when this study is published after peer-review.
29/30 Before I conclude,

Whey protein is liver safe
Whey protein does not cause kidney stones
Pure whey/different blends of whey varieties are safe
Whey + herbs -use with caution (ideally, don't use)
Pure plant proteins (soy/pea) are safe, plant proteins + herbal blends aren't.
30/30

This is so cool

A Twitter friend, @_rohitag made a nice little web-app that helps you compare the brands we have analyzed, based on tested features.
protein-project.vercel.app

Maybe this can be improved upon, more brands analyzed, more labs involved with help of public funding. Image

STAY WITH ME.

A few years ago, a patient was referred to me because he was diagnosed with complicated cirrhosis. He had an infection which led to a condition called hepatic encephalopathy (brain failure due to high ammonia levels). The treatment largely involved ammonia reducing therapies. One drug was central to this - Rifaximin - a non-absorbable antibiotic that reduced ammonia in the body. I prescribed him Rifaximin for 6 weeks and advised him follow-up.

He came back to me, not after six weeks, but in 4 weeks, this time, in liver coma (worst stage of brain failure - due to very high ammonia). He spent two days in the ICU and six days in total in the hospital. His hospital bill was close to INR 80,000. He had no insurance and his wife borrowed the money from neighbors and friends to clear hospital dues.

Upon questioning, I found that he was not taking the Rifaximin drug I had prescribed. He was only on the other two drugs (one, a syrup called lactulose for improving ammonia clearance in gut). I was furious, because the patient spent a whole week unecessarily in the ICU and wasted so much money that he never had - just because he was "not compliant" to my orders. I decided it was time for me to school him a bit.

But I was wrong. He was compliant. He had purchased Rifaximin and was on it. For 15 days. Thereafter, he could not afford it. He was an autorickshaw driver who shuttled school children every morning and evening. He could hardly make ends meet. He had two children of his own. The Rifaximin brand I prescribed him was 42 rupees per tablet. He had to consume two a day - which would mean 2520 rupees a month. He just did not have that money - so he skipped it - to not compromise on other important matters - childrens education and food.

He was confused and scared about opting for a cheaper version of Rifaximin because one, he was unsure about the quality of Rifaximin that was not prescribed by me and two, he was "scared" that I would scold him for buying a cheaper Rifaximin and if that got him into trouble.

I was confused and scared about prescribing a cheaper version of Rifaximin because one, I was unsure about the quality of Rifaximin that was not "a good promoted brand" and two, I was "scared" that his family would scold me for prescribing a cheaper Rifaximin and if that got him into trouble.

It is heartbreaking that many doctors still simply don’t trust generic medicines. Too often, they worry that these cheaper options are lower quality or might cause more problems than the big, famous brands. This fear leads them to prescribe expensive drugs instead, and the real tragedy is that it pushes vital healthcare out of reach for the ordinary people who need it most - like my patient.

This narrative, that generic drugs 'are never good' and that only big pharmaceutical marketed drugs are what works has been deeply ingrained into doctors and patients alike - I do not know by whom and since when. Looking back, these strong emotions were based on either opinions, testimonials or second- and third-hand information. Not evidence.

Like I said. Stay with me. This is life changing and will disrupt the drug market in India. Here are the results of The Citizens Generic vs. Brand Drugs Quality Project.
1/11Image
With your help, we analyzed 131 different medicine samples from pharmacies - ranging from expensive top brands to "free" government generics.

This included the highest prescribed and selling (most expensive) branded drugs, generics marketed by the same big brands (branded and local pharma generics), government supplied generics [Central Govt. - Jan Aushadi and State Government - Kerala Medical Services Corporation Limited (KMSCL)], and trade generics [sold at hospital pharmacies and special generic pharmacies - Dava India, Generic Aadhar)

The question: Is the expensive stuff actually better?
2/11Image
The Test
We took 22 types of common (essential) medicines (for heart, pain, antibiotics, liver, sugar) from these 7 different sources, and sent them to an accredited lab - Eureka Analytical Services Pvt. Ltd. in Kundli, Sonipat, an FSSAI-notified and US-FDA and NABL/ISO 17025 accredited laboratory providing comprehensive pharmaceutical, API, and drug testing services.

We tested 5 quality parameters according to standards of Indian Pharmacopeia:
✅ Drug content or assay
✅ Dissolution
✅ Uniformity
✅ Impurities
✅ Physical appearance
