Three questions answer this: what are you getting, how does it compare to what else is available, and what does it cost per day. Each one is answered below.
| Product | 14-day cost | Delayed release | Post-AB specific | Gut lining repair | AM/PM system |
|---|---|---|---|---|---|
| Bifilac (pharma) | Rs. 210 | No | No | No | No |
| Darolac (pharma) | Rs. 178 | No | No | No | No |
| Darolac IBS | Rs. 490 | No | No | No | No |
| Wellbeing Nutrition Daily Probiotic | Rs. 327 | Yes | No | No | No |
| Aegis Protocol | Rs. 2,499 | Yes | Yes | Yes | Yes |
Wellbeing Nutrition uses delayed release technology for general daily use. Aegis is the only product using it specifically for post-antibiotic recovery, combined with Zinc Carnosine and L-Glutamine for structural gut lining repair. No other product in India combines all five elements.
You already spent Rs. 300 to 600 on the antibiotic that caused the disruption. The course of treatment is incomplete without addressing what happened to your gut. At Rs. 178 per day for 14 days, Aegis costs less than most people spend on a single restaurant meal.
A cheaper probiotic uses generic strains, standard capsule shells, and no gut-lining repair ingredients. The Rs. 200 difference in production cost between a generic probiotic and Aegis compounds across every ingredient and every processing step. The price reflects the formulation, not the branding.
The cost of Rs. 2,499 is the cost of a structured 14-day recovery. The cost of doing nothing is months of suboptimal gut function and the persistent symptoms that come with it. Most people spend more than Rs. 2,499 on the follow-up doctor visits that persistent post-antibiotic symptoms generate.
Antibiotics wipe out the good bacteria too. A generic probiotic will not fix it. Here is why.
Most Indian pharmacy probiotics use standard gelatin capsules that dissolve in stomach acid, generic species names without strain designations, and address only one of the three mechanisms of post-antibiotic gut damage.

| LGG ATCC 53103 (WGO Grade A) | ✓ 10×10⁹ CFU specified | ✗ None have this designation |
| Bifidobacterium (specified strain) | ✓ Bl-04, 5×10⁹ CFU | ✗ Generic or absent |
| Zinc Carnosine (mucosal repair) | ✓ 75mg Polaprezinc | ✗ Not in any |
| L-Glutamine (epithelial energy) | ✓ 500mg pharma grade | ✗ Not in any |
| HPMC delayed release capsule | ✓ AM and PM both | ✗ Standard gelatin (acid-soluble) |
| Mechanisms addressed | ✓ All 3 | 1 only (microbial depletion) |
Stomach acid sits at pH 1.5 to 3.5. Standard capsule shells dissolve in it completely. What happens to the bacteria inside determines whether your probiotic actually works.
Every ingredient is chosen for clinical evidence in post-antibiotic recovery specifically, not general wellness. Doses are standardised to clinically validated levels. Nothing is hidden behind a proprietary blend.
Recovery is not instant and it is not linear. Understanding what to expect at each stage helps you stay the course, especially through days 3 to 5 when things can temporarily feel worse before improving.
Your microbiome is at its most depleted right now. Symptoms are typically at their peak. Begin Aegis on the day you take your final antibiotic dose. Do not wait for symptoms to worsen. S. boulardii begins competing with harmful bacteria for intestinal binding sites within hours of the first dose.
As beneficial bacteria begin recolonising, there can be a temporary increase in gas and bloating. This is fermentation activity, a sign of recovery, not deterioration. This is the most common point at which people mistakenly stop their protocol. Continue through days 3 to 5. Improvement typically follows in days 5 to 7.
Most people notice meaningful improvement in stool consistency and reduced urgency by days 5 to 7. Bloating begins to reduce. Appetite typically improves. Energy recovers as nutrient absorption normalises. Zinc Carnosine and L-Glutamine have had sufficient time to begin supporting gut lining repair.
Beneficial bacteria populations are growing and consolidating. Digestion returns toward baseline. Most people feel significantly better than day 1. Continue the protocol. Stopping early is one of the most common recovery mistakes. The bacterial colonies established in week 1 need week 2 to stabilise.
The majority of people completing the full 14-day protocol reach near-normal digestive function by this point. Bowel regularity restored, bloating minimal, energy normal. Complete all 14 days even if you feel better earlier. The final days consolidate everything built in weeks 1 and 2.
Every answer below references peer-reviewed clinical literature. These are the questions most frequently asked about post-antibiotic gut recovery in India.
Without structured intervention, the gut microbiome can take 3 to 6 months to return to baseline after a single broad-spectrum antibiotic course. A landmark 2018 study by Suez et al. in Cell followed patients post-antibiotics and found that those who took standard generic probiotics recovered their native microbiome more slowly than those who took nothing. The critical window is the 14 days immediately after your final dose, when disruption is highest and receptivity to recolonisation is greatest.
Three specific failures. First, delivery: standard gelatin capsules dissolve at stomach pH 1.5 to 3.5, destroying over 90 percent of bacteria before reaching the intestine. Second, strain specificity: generic species names do not carry the clinical evidence of designated strains. The 12 RCTs covering 1,499 patients for LGG were done with ATCC 53103, not generic L. rhamnosus. Third, mechanism coverage: these products address only microbial depletion. Post-antibiotic damage also involves mucosal structural damage (requiring Zinc Carnosine) and epithelial energy deficit (requiring L-Glutamine).
Clinical evidence supports a combination approach. Saccharomyces boulardii CNCM I-745 is the only probiotic that can be started during the antibiotic course because it is a yeast unaffected by antibiotics, with 21 studies and WGO Grade A evidence. After the course ends, Lactobacillus rhamnosus GG ATCC 53103 has 12 RCTs and 1,499 patients behind it. Bifidobacterium lactis Bl-04 addresses the large intestinal compartment. All three must be delivered in HPMC delayed release capsules to survive stomach acid. Zinc Carnosine and L-Glutamine address the two additional damage mechanisms no probiotic can cover.

Start on the day of your final antibiotic dose. For Saccharomyces boulardii specifically, you can begin on day one of the antibiotic course since it is a yeast and completely unaffected by antibiotics. For bacterial strains (LGG ATCC 53103, B. lactis Bl-04), start from the day after your final dose. The 14-day post-antibiotic window is when bacterial recolonisation is most effective. Do not wait until symptoms worsen.
Antibiotics cause mucosal structural damage alongside microbial depletion. They disrupt tight junction proteins (ZO-1 and occludin), reduce mucus layer thickness, and suppress secretory IgA. This physical gut wall compromise cannot be corrected by probiotics. Zinc Carnosine (Polaprezinc 75mg) has RCT evidence published in Gut showing protection against intestinal permeability increases. L-Glutamine addresses the simultaneous epithelial energy deficit: antibiotics deplete systemic glutamine, the primary fuel for gut lining cells, precisely when those cells need maximum energy for repair.

Econorm contains S. boulardii CNCM I-745 and has genuine clinical evidence for during-course antibiotic-associated diarrhoea prevention. It is a good product for that purpose. Aegis Protocol addresses the complete post-antibiotic picture: it adds LGG ATCC 53103 for microbiome restoration, Bifidobacterium lactis Bl-04 for large intestinal recolonisation, Zinc Carnosine for mucosal repair, and L-Glutamine for epithelial energy. All in HPMC delayed release capsules. Different product, different scope, different standard.
The AM capsule containing Saccharomyces boulardii CNCM I-745 and Zinc Carnosine can be taken from day one of an antibiotic course. S. boulardii is a yeast and completely unaffected by antibiotics. The PM capsule containing bacterial strains (LGG ATCC 53103, B. lactis Bl-04) should be started from the day after your final antibiotic dose. Consult your physician before starting any supplement if you have a pre-existing medical condition.
CNCM I-745 is the culture collection number identifying the exact genetic strain deposited at the French National Collection of Microorganism Cultures. All 21 published studies establishing efficacy for antibiotic-associated diarrhoea, C. difficile toxin neutralisation, and secretory IgA stimulation were conducted with this specific designation. Generic Saccharomyces boulardii without CNCM I-745 may be a different organism with no shared evidence base. Strain designation is the difference between a clinically validated intervention and an unvalidated supplement.
