How to Read a Protein Powder Label — The Indian Consumer’s Guide

The Label Is a Marketing Tool, Not a Nutrition Document

Every protein powder label is designed by a marketing team before it reaches a nutritionist. The biggest numbers go in the biggest font. The things that matter most are buried in small print. Once you know what to look for, choosing a protein powder becomes a lot simpler.

Step 1: Find the Serving Size

Everything on the label is stated per serving. The serving size is often manipulated to make numbers look better. A powder might list 25g of protein per serving, but the serving size is 40g (a heaped scoop), meaning only 62.5% of the powder is protein. Compare brands on a per-100g basis to make fair comparisons. Divide the protein grams by the serving size in grams and multiply by 100. Anything above 70% protein by weight is strong.

Step 2: Check the Protein Source

The ingredients list shows protein sources in descending order by weight. The first ingredient should be a quality protein: whey concentrate, whey isolate, pea protein isolate, soy protein isolate, or yeast protein. If the first ingredient is maltodextrin, oats, or a "protein blend" without specifics, be cautious.

Step 3: Spot Amino Acid Spiking

Amino acid spiking is the practice of adding cheap individual amino acids — taurine, glycine, creatine, alanine — to inflate the total protein reading on a nitrogen test. These amino acids are far cheaper than whole protein and do not contribute to muscle building the way complete protein does. If you see individual amino acids listed in the ingredients (not a full amino acid profile in the nutrition facts), the protein count may be inflated.

Step 4: Look at the Carbohydrate and Sugar Content

A clean protein powder should have fewer than 5g of carbohydrates per serving and under 2g of sugar. High sugar or carb counts mean the product is diluted with fillers or designed as a mass gainer rather than a clean protein supplement. Check for maltodextrin specifically — it has a glycaemic index higher than table sugar and is often not listed as sugar on Indian labels.

Step 5: Check for Certifications

In India, look for FSSAI registration as a baseline. More meaningful certifications include Informed Sport (tests for banned substances), third-party lab testing (look for a QR code or batch number you can verify), and Vegan Society certification for plant-based claims. The Pink Tiger certification, developed in India, tests for adulteration and is a reliable indicator of label accuracy for Indian protein brands.

Step 6: Read the Full Ingredients List

Short is good. If the ingredients list requires reading glasses and three passes to understand, that is a red flag. A clean protein powder has 5– 10 ingredients. Anything with artificial colours, hydrogenated oils, or long chemical names you cannot pronounce is likely not worth the money — regardless of the protein count on the front.

Quick Reference Checklist

Protein above 70% by weight. Sugar under 2g. Carbs under 5g. Named protein source as first ingredient. No individual amino acids spiking the count. FSSAI registered. Third-party tested. Ingredients list under 10 items.
