It really works!

Amazing product. I can genuinely feel the difference in my immunity within just a couple of days of use. The recurring cold and throat irritation I used to deal with every now and then has simply stopped bothering me.

In my experience, The Stack makes the best supplements in its category on the market. I've pretty much bought all of their products at this point, and every single one has worked amazingly well. I think it comes down to the high-quality ingredients they source from world-renowned manufacturers. Kudos to The Stack's founders and team for challenging and changing the Indian supplements market. Also, a special thanks for running great discounts and sales around times like this — it's what let me pick up this amazing product and try it for myself. I'd never even heard the term "postbiotic" before this; it was through The Stack that I first learned about it. Keep up the great work, and please keep bringing more useful, innovative products our way.

Controls allergy

I was extremely doubtful of its claims but tried anyways as "how bad can it get anymore"?. I was on anti allergy medication almost every day as anything change in temperature/wind/ dust /sitting under a tree could lead to a severe allergy reaction of runny nose/itching and watery eyes/sniffles/sneezing a 100 times. I am on the STACK for 6months now and except for 2 days did not have to reach out for Allegra/Montec LC.Its like a miracle med for me. I feel better in the morning/sleep better. Thankyou for getting this to India . And surely the product does what it says.

A Game Changer for Daily Wellness!

This EpiCor 500mg postbiotic is hands-down one of the best additions I’ve made to my supplement routine. I love that it targets both gut health and immune support in a single daily capsule. Since I started taking it, my digestion has felt much smoother and more regular, and my overall immune resilience has noticeably improved. No stomach upset, no weird aftertaste—just a high-quality product that actually delivers on its promises. Will definitely be reordering!

I'm still trying it out

I'm still trying it out. Too soon to sat, but I had no unpleasant side effects so far, which makes me want to try all the supplements released by this brand. Kindly make the capsules smaller, difficult to swallow for people with GERD. Good brand.

The product quality is something I’d comment on in detail after 8 weeks of usage

The product quality is something I’d comment on in detail after 8 weeks of usage. However, a couple of things at this juncture - Noticed inc in mucosal secretion for sure. Product seems to be science backed.
Packaging - The bottle and the cap feel kinda flimsy. Can be improved a lot.
Also, I did notice a bit of odour as the bottle emptied to the last week worth of capsules… The packaging can be definitely better!
Looking forward to continuing the usage for a few weeks.

Excellent immune support supplement I have tried to date

Excellent immune support supplement I have tried to date, and results are showing.

Clinically studied postbiotic that supports immune balance and gut health from within.
Each serving delivers 500 mg of EpiCor®, a whole-food fermentate proven to strengthen your body’s natural defences and support a resilient gut microbiome.

Backed by Clinical Science

Gut Immune Support is formulated with EpiCor® 500 mg, a patented whole-food fermentate backed by more than a decade of human clinical studies.
EpiCor® helps your immune system respond efficiently - promoting resilience without overstimulation - while improving microbial balance in the gut.

How It Works

EpiCor® is a postbiotic, meaning it delivers bioactive compounds that:

  • Feed beneficial gut bacteria
  • Strengthen mucosal and immune barriers
  • Support antibody production and NK-cell activity
  • Reduce frequency and duration of seasonal colds

The result: a stronger, calmer immune system and a more balanced gut environment.

Why It Matters

Up to 70 percent of your immune cells reside in your gut. A well-balanced microbiome helps you stay energised, less inflamed, and better protected year-round. Gut Immune Support with EpiCor® helps restore that balance naturally.

Clean, Transparent Formulation

  • 500 mg EpiCor® per serving
  • No added sugar, colours, or preservatives
  • Made in India using globally sourced ingredients under global quality standards

Directions

Take 1 capsule daily with or without food. Safe for long-term, everyday use.

  • Take one capsule daily with water, preferably with a meal.
  • For best results, use consistently.

Warnings:

  • Consult your healthcare provider before use if you are pregnant, nursing, taking any medications, or have any medical conditions.
  • Do not exceed the recommended dose.
  • Keep out of reach of children.
  • Store in a cool, dry place.
  • Discontinue use and consult your healthcare provider if any adverse reactions occur.

EpiCor®, Inulin, hydroxypropyl methylcellulose capsule

FAQs

Your questions answered.

What is Daily Gut Defender?

A targeted immune support supplement containing EpiCor®, a clinically proven postbiotic that strengthens your immune system.

How is it different from regular immune supplements?

EpiCor® works within 2 hours and keeps working 24/7. It's backed by 15 clinical trials and supports both immunity and gut health.

When do I take it?

One capsule daily, anytime, with or without food.

How soon will I see results?

EpiCor® starts working within 2 hours, though best results come with consistent daily use.

Does it need refrigeration?

No, it's stable at room temperature - just store in a cool, dry place.

Can I take it year-round?

Yes, it's designed for daily use and provides year-round immune support.

Can I take it when I'm feeling under the weather?

Yes, it can be taken daily, whether you're feeling well or not.

What's the difference between this and probiotics?

While probiotics are live bacteria, postbiotics are the beneficial compounds created when beneficial bacteria ferment ingredients. Think of it like yogurt vs. the nutrients you get from yogurt. EpiCor® is created through a specialised fermentation process, making it more stable and fast-acting than probiotics. It doesn't need refrigeration because it's not "alive" - it's the beneficial end product of fermentation.
