The funding comes months after the startup raised its first institutional round of ₹5.5 Cr. It claims to have grown 5X since then and is now targeting 6-7X growth in FY27 compared with FY26.
Founded by Shreya Jain and Kshitij Rihal in 2024, Bengaluru-based The Stack sells supplements to support sleep, recovery and gut health. The formulations of its five supplements that combine magnesium bisglycinate, glycine, prebiotics and probiotics.
The startup claims that one in three customers places a second order within six months, while several opt for subscriptions spanning six to twelve months. Its top 10% of customers account for 30% of revenue, with referrals and word of mouth driving new customer acquisition.
“We’d rather have five products people keep coming back to than fifty they try once. We’re playing a long game, and our customers are rewarding that patience,” said Rihal, cofounder of The Stack.
The startup aims to become one of India’s most trusted supplements brands over the next three years, with a focus on transparent formulations, clinically studied ingredients and a quality-first approach to product development.
The Stack competes with brands such as Wellbeing Nutrition, Supply6 and Trunativ in India’s health and wellness supplements market.
The funding comes amid growing demand for dietary supplements in India, driven by rising awareness of preventive healthcare, the increasing availability of global brands and the use of supplements to support the management of chronic conditions.
India’s dietary supplements market was valued at $5.8 Bn in 2025 and is projected to grow to $6.6 Bn in 2026 and $12.4 Bn by 2033, at a CAGR of 9.5% from 2026 to 2033, according to Grand View Research.

In July, D2C nutrition and wellness startup Supply6 raised about $5 Mn in a funding round led by Unilever Ventures, with participation from existing investor Zeropearl VC. Before that , nutrition-focused brand TruNativ raised $30 Mn in a Series B round from US-based investor OrbiMed.
