Indian brands turn to yeast protein as whey costs soar past ₹4,500/kg

Fermented yeast protein is a single-cell protein produced through controlled microbial fermentation rather than extracted from dairy or plants, and it now costs Indian brands roughly ₹700–800 per kg of raw material at scale, compared with ₹2,800–2,900 per kg for whey protein concentrate, according to industry estimates cited by Mint on 3 October 2026.

The price gap matters because whey protein powder has gone from around ₹1,000 per kg in 2023 to more than ₹4,500 per kg today. Supplement-grade whey concentrate has climbed from about ₹4.5 lakh per tonne in mid-2023 to nearly ₹30 lakh per tonne now. The root cause is structural: India produces large volumes of milk but relatively little cheese, so supplement makers depend on overseas suppliers for whey ingredients. Supply constraints abroad have compounded the problem. The result is a cost squeeze that is forcing reformulation across the nutrition category at a time when India's protein supplements market, valued at ₹7,461 crore in 2024, is projected to reach ₹13,186 crore by 2033, according to the India Brand Equity Foundation.

What changed

Hindustan Unilever Limited (HUL) is the most recent and highest-profile brand to move. The company has launched Horlicks Protein in ready-to-drink and powder formats, using fermented yeast protein as the primary protein source. Horlicks Protein sachets are priced at around ₹83 per serving; the ready-to-drink shake costs ₹120. Rajneet Kohli, executive director of HUL's foods division, told Mint that yeast protein offers the required protein quality while balancing cost and digestibility, and that the format is aimed at expanding the category beyond gym users. HUL estimates only about 3% of Indian households currently consume protein products.

The move is notable because HUL is not a specialist nutrition company. Its entry signals that yeast protein has crossed from niche to mainstream consideration.

Other brands moved earlier. Marico's Cosmix (Marico acquired a 60% stake in Cosmix Wellness for ₹226 crore in February 2026, valuing the company at about ₹375 crore) started with plant-based supplements, then in January 2025 introduced a plant-and-yeast protein blend, and has since developed a dedicated yeast-protein range using what it calls its Fermagut fermentation process. SuperYou, backed by actor Ranveer Singh, was among the early entrants and now reports repeat purchase rates above 60% on its yeast-protein range. Mille, co-founded by Shauravi Malik, landed on yeast protein after struggling with the taste of plant proteins. Mumbai-based The Good Bug says it began selling about 35 tonnes of yeast protein products per month as of September 2026.

The amino-acid profile is a recurring selling point. Keshav Biyani, co-founder of The Good Bug, described yeast protein as sitting "in the sweet spot of whey and plant" protein, with a smoother texture than plant proteins and better digestibility than whey for consumers who experience lactose-related discomfort. That claim has intuitive logic: yeast is dairy-free and therefore suitable for lactose-intolerant consumers, and fermentation can improve bioavailability. Independent clinical data comparing yeast protein directly with whey or pea protein in Indian adult populations is not yet widely published, so the digestibility and amino-acid claims should be read as brand-level assertions until peer-reviewed studies confirm them at scale.

Yeast protein is not immune to cost pressure either. Nikunj Biyani of SuperYou said yeast protein prices have risen 20% over the past six months. Most brands currently import the ingredient. SuperYou has identified an Indian manufacturing partner but says domestic production has not yet scaled up, and local manufacturing requires significant capital investment.

What buyers and cooks should do

If you currently buy whey protein supplements, the price you pay at retail is unlikely to fall soon. Whey-based products are priced at roughly ₹4,500 per kg at retail; yeast-protein products are priced at around ₹2,000 per kg, according to industry estimates in the Mint report. That gap is real, though actual savings depend on serving size and brand.

Before switching, check the label for a few things. Fermented yeast protein is dairy-free and generally suitable for vegetarians, but it is not always vegan (check for added ingredients like casein or honey). It is not inherently gluten-free either: some yeast strains are grown on grain-based substrates, so people with coeliac disease or gluten sensitivity should look for an explicit gluten-free certification on the pack, not just the word "yeast."

The ICMR recommends 60g of protein per day for an average adult Indian, and average intake sits at 47g, according to the India Brand Equity Foundation data cited in the Mint report. A protein supplement, whether whey or yeast-based, is one way to close that gap, but whole-food sources (legumes, dairy, eggs, soy) remain cheaper per gram of protein than any packaged supplement at current retail prices.

For home cooks interested in the ingredient itself, fermented yeast protein powder is functionally similar to other protein powders: it dissolves in liquids, can be blended into smoothies, and has a milder flavour than most plant proteins. Mille's co-founder noted that taste was the deciding factor in choosing yeast over plant protein, and SuperYou is developing yeast-protein biscuits, which suggests the ingredient works in baked formats too.

FSSAI has not yet released specific labelling or compositional standards for fermented yeast protein as a distinct category. Until it does, the regulatory framework that applies is the general one for protein supplements under the Food Safety and Standards (Health Supplements, Nutraceuticals, Food for Special Dietary Use, Food for Special Medical Purpose, Functional Food and Novel Food) Regulations, 2022. Buyers should look for FSSAI licence numbers on pack and treat any product without one with caution, regardless of how the protein source is described.
