Plant protein has quietly become one of the fastest-moving categories in Indian supplements — and one of the most confusing to shop. Every brand claims “clean,” “easy to digest,” and “no bloating“. Prices range from ₹440/kg to nearly ₹6,000/kg for what’s often the same pea or soy isolate with different marketing.
I pulled and analyzed sales data across 500 plant protein listings on Amazon India — parsing pack sizes, protein-per-scoop claims, and protein source from each listing — to see what the category actually looks like once you strip away the label copy.
This post works both ways: skip straight to a specific recommendation, or read through the full pricing and market-share analysis behind it. Either way, every pick below is backed by the same dataset — no guesswork.

The Category, at a Glance
The plant protein category on Amazon India tracked here does roughly ₹16.9 crore in revenue across 500 listings. Unlike whey — which is dominated by 2-3 giants — plant protein is genuinely fragmented, which is good news if you’re willing to look past the top 2-3 names.
Pea, Soy, Yeast & Brown Rice: Which Costs More?
| Protein Source | Median Price / kg | Revenue Share | What It’s Good For |
|---|---|---|---|
| Soy Protein | ₹1,287 | 6.0% | Cheapest complete protein — full amino profile, budget-friendly |
| Brown Rice Protein | ₹1,268 | 0.5% | Niche, hypoallergenic option — small market, limited brand choice |
| Pea Isolate | ₹1,695 | 19.7% | Good middle ground — solid amino profile, widely available |
| Pea + Rice Blend | ₹2,090 | 25.8% | Most popular format — blending fixes pea’s weak amino acids with rice |
| Fermented Yeast Protein | ₹2,350 | 25.6% | Newest trend — marketed on “no bloat,” commands the highest premium |
Verdict: Soy protein is the value leader by a wide margin — nearly 2x cheaper per kg than fermented yeast protein, for a comparably complete amino acid profile. If digestion comfort is your main concern, pea + rice blends are the tested middle ground; yeast protein is priced as a premium “no bloat” solution, not because it costs more to make.
Who Actually Sells Plant Protein
No single brand dominates the way Tide or Ariel dominate detergent. The top 7 brands combined hold just under 60% of revenue — this is a genuinely open category with real room for smaller players.
Plant Protein — Brand Revenue Share (Amazon India)
| Brand | Revenue Share | Positioning |
|---|---|---|
| Cosmix | 14.8% | Category leader — clean-label positioning, pea + rice isolate blends |
| Millé: A Supergrain Co. | 9.5% | Fermented yeast protein specialist — rides the “no bloat” trend hardest |
| Nutrabay | 9.0% | Value + volume play — cheapest pea isolate options with strong review counts |
| TrueBasics | 8.0% | Premium positioning across both yeast and blend formats |
| NAKPRO | 6.8% | Best value-for-money brand overall — cheapest soy and pea options |
| OZiva | 5.0% | Established wellness brand, mid-premium pricing |
| BEASTLIFE | 5.0% | Fitness-focused, fermented yeast protein |
What Pack Size Actually Sells
Unlike whey (where 5-10kg bulk packs dominate) or detergent, plant protein buyers overwhelmingly choose ~1kg packs — this single band drives 58% of category revenue. Smaller packs under 600g (largely 500g “trial” or premium-priced formats) account for another 26%, but larger multi-kg packs barely register.
| Pack Size | Why It Sells |
|---|---|
| ~1kg (900g–1.1kg) | The default size across nearly every brand — easiest to compare price per kg since almost everyone offers this exact band |
| Under 600g | Common for fermented yeast protein brands (Millé, etc.) — often priced at a steep per-kg premium versus their own 1kg packs |
| 1.1–2kg | Rare — a handful of brands offer this for regular users, usually at a modest per-kg discount |
| Over 2kg | Almost nonexistent — plant protein hasn’t developed the “bulk bag” culture that whey has |
One pattern worth flagging: several yeast-protein brands sell the same product in both 500g and 1kg sizes — and the 1kg size is reliably cheaper per kg. If a brand offers both, the smaller pack is rarely the smart buy.
Price Tiers, Mapped to Brands
- Budget tier (under ₹1,798/kg): Nutrabay, NAKPRO, Asitis Nutrition, and Sparkfusion dominate here — this is where soy protein and value pea isolates live.
- Mid tier (₹1,798–₹2,480/kg): Cosmix, TrueBasics, BEASTLIFE, and OZiva — most pea+rice blends and standard yeast protein SKUs land here.
- Premium tier (over ₹2,480/kg): Millé, TrueBasics, ORIGIN NUTRITION, and Nutrilite — smaller pack sizes, fermented yeast protein, and established wellness brands charging for trust.
Notice TrueBasics appears in both mid and premium tiers — like the detergent brands we’ve covered before, the same brand can sit in different price bands depending on which product line and pack size you pick.

| Nutrilite (Amway) | Blend | 1kg | ₹3,660 | — | 4.2★ (2,679 reviews) | Check Price → |
Verdict: NAKPRO’s pea isolate at ₹799/kg with 28g protein per scoop is the best pure value pick in the entire dataset — cheaper per kg than most soy options while delivering more protein per scoop than most premium blends. If you want the most-trusted bestseller regardless of price, Nutrilite’s 2,679 reviews at 4.2★ is the safest mainstream choice.
How to Actually Choose
Skip “best plant protein” as a question — it doesn’t have one answer. Run through this instead:
- Check protein-per-scoop, not just pack size. Two 1kg tubs can deliver very different total protein depending on scoop size and protein-per-scoop — a 28g/scoop product genuinely gives you more than a 23g/scoop one at the same price.
- Decide if “no bloat” is worth the premium. Fermented yeast protein costs roughly 2x soy protein per kg. If you’ve had digestion issues with pea-based products before, this may be worth paying for. If not, you’re paying for a marketing claim you don’t need.
- Don’t assume the smaller pack is a good trial size. Several brands price their 500g packs at a real per-kg premium over their own 1kg version — buy the bigger pack even if you’re not sure you’ll finish it.
- Weigh review count as much as rating. A 4.2★ product with 2,679 reviews (like Nutrilite) is a far safer bet than a 4.2★ product with 100 reviews — small review counts swing easily.
This is exactly the kind of category math that gets skipped in “Top 10 Plant Proteins” roundups — because ranking by price per kg and protein per scoop takes actual data, not just brand reputation.

Frequently Asked Questions
What is the average price per kg of plant protein in India?
Based on Amazon India listings, plant protein prices range from about ₹800 to ₹3,700 per kg for mainstream products, with pricing varying significantly by protein source — soy is cheapest (~₹1,287/kg median), fermented yeast protein is priciest (~₹2,350/kg median).
Is pea protein or soy protein better value?
Soy protein is consistently cheaper per kg than pea protein in the Indian market — roughly 25-30% less on average — while offering a comparably complete amino acid profile. Pea protein is more widely available and often blended with rice to improve its amino profile.
Why is fermented yeast protein so much more expensive?
Fermented yeast protein commands the highest price premium in the category, largely due to “no bloat” and “easy to digest” marketing claims rather than higher production costs. It’s a newer entrant riding strong demand from people who’ve had digestive discomfort with other plant proteins.
Which plant protein brand has the best reviews in India?
Nutrilite (Amway) has the highest review count among top-selling plant proteins (2,679 reviews at 4.2★), making it the safest mainstream choice by review volume. Cosmix leads the category in overall revenue share at 14.8%.
Should I buy a 500g or 1kg plant protein pack?
1kg packs are almost always cheaper per kg than 500g packs of the same product — several brands offering both sizes price the smaller pack at a real per-kg premium. Buy the 1kg size unless you’re specifically testing a new brand.
