Protein and Supplement Subscriptions for Shopify Brands in India

Sell whey, plant protein, creatine, electrolytes and daily vitamins on plans timed to the tub: a 1kg pack every month, a 90-day course paid upfront, a stack that ships together. Offer prepaid, pay-as-you-go and AutoPay on UPI and cards side by side, with StackBack, the subscription & repeat-revenue platform for Indian D2C brands on Shopify. Our team takes you live in 2 days.

A 1kg Tub Lasts About a Month The Routine Breaks on Day 31

One 33g scoop a day empties a 1kg tub in about 30 days. Creatine at 5g a day lasts 50 days from a 250g pack. Supplements work when they're taken every day, so the refill has to arrive before the gap.

  • Prepaid for the committed: A 3- or 6-month course paid once, at your deepest discount. The Stack runs its prepaid plans at 35% off.
  • Pay-as-you-go for first-timers: A payment link before each tub, for customers still settling on a flavour.
  • AutoPay on UPI and cards for the monthly tub: The customer approves once. Each tub is paid on schedule into your own gateway, with a notice 48–72 hours before.
  • Stacks, not single tubs: Whey, creatine and a multivitamin as one bundle on one plan.
  • A landing page for every stack: One-click pages for each plan and offer, ready for Meta and Google traffic. The Func Lab sells through StackBack's subscription landing pages and bundles.
  • Sachets in early access: Try-before-you-buy sampler plans that roll into a full tub.

On StackBack: The Stack runs prepaid plans at 35% off, with 4.8× LTV and 26% higher AOV. Lightyears Health sells its subscriptions through GoKwik.

Why Supplement Customers Fall Off And How to Keep the Routine Running

Supplement churn rarely comes from the product. The tub empties, the reorder slips by a week, and the habit is gone. Or the customer buys the next tub on a marketplace, where they can't be sure it's genuine.

Most brands chase that customer back with coupon codes and retargeting. It works once, and the cost comes back every month.

  • Sell the plan where the tub is sold, with subscribe-and-save on the product page and cadences matched to pack size: 1kg monthly, 2kg every two months.
  • Keep flavour fatigue in-house with flavour swaps from the portal, so a bored subscriber tries your mango, not someone else's.
  • Reward consistency with a shaker on the 2nd delivery and a sampler on the 6th. You pick the gift and the delivery.

Result: Customers who stay on the routine, with every refill coming from your store, genuine and on time.

Frequently Asked Questions

How do I launch a protein subscription on my Shopify store in India?

Integrate StackBack with your Shopify store, and our team sets up your plans on prepaid, pay-as-you-go and AutoPay on UPI and cards, with subscribe-and-save widgets on your product pages. We take you live in 2 days, with no developer needed on your side.

How often should a protein subscription ship?

Match it to the tub. A 1kg pack at one scoop a day lasts about a month, and a 2kg pack about two. Offer monthly and two-monthly cadences, and let customers move between them from the portal as their training changes.

Prepaid or AutoPay for supplements?

Offer both. Prepaid suits a 3- or 6-month course and usually carries your biggest discount: The Stack runs prepaid plans at 35% off. AutoPay on UPI and cards suits the monthly tub. Pay-as-you-go suits first-timers who want a payment link before each delivery.

Can customers change flavour mid-subscription?

Yes. They swap flavours or pack sizes from the portal before the next delivery, skip a month, pause, or add a product to an upcoming order.

Can I sell supplement stacks on subscription?

Yes. Fixed stacks, mix & match and build-your-own boxes sell once or on a plan, and every stack can have its own landing page for ads. The Func Lab sells through StackBack's subscription landing pages and bundles.

Does StackBack work with GoKwik and other quick checkouts?

Yes. StackBack is the only subscription platform that works with India's quick checkouts. Prepaid and pay-as-you-go plans check out on GoKwik, Shopflo, Shiprocket Checkout, Razorpay Magic Checkout, Cashfree and FlexyPe. Lightyears Health sells its subscriptions through GoKwik.

What happens if an AutoPay payment fails?

It's retried automatically. After three failed retries, the subscription pauses or moves to pay-as-you-go, whichever you choose. On pay-as-you-go, the customer gets a payment link instead of losing their plan. Nothing ships unpaid, and every payment settles in your own gateway account. How AutoPay works.
