Problem
Calcium matters most in the growth years, but supplements feel like medicine. I wanted something young people would actually enjoy taking.
My role
Founder of NutriCal.
Outcome
FSSAI Central Licence and letters of intent from 7 organisations
How I built it
Each CalShield diskette combines calcium with Vitamin D3, Vitamin K2 and magnesium. It comes in two flavours, chocolate and vanilla, and every box holds 21 daily sachets.
Where it is now
NutriCal holds an FSSAI Central Licence (No. 11525997001220), issued in December 2025.
Seven organisations have signed letters of intent: Pragati Metal Works for 1,000 units for its employees' children and CSR work, Aayush Medical Store in Surat for 800 units, the Rotary Club of Ahmedabad West for a 700-box school pilot, the Ramlal J. Bagadia Charitable Trust for a 500-unit pilot for underprivileged children, Mohar Gems and Jewels for 150 boxes, Suresh U. & Co. for a stall at Bhayandar railway station, and PowerPeaks Athlete Lab for its endurance athletes.
Families can pre-book, and schools, NGOs and organisations can contact me directly for bulk orders.

What worked
Treating it as a snack, not a supplement. The goal was to make an important part of nutrition something children actually look forward to.
