Nearly half of health product consumers abandon their purchase because nobody explains how to use it properly

This Stack Includes Supplement Assist™

Gut optimization requires consistent daily use for weeks before the shift becomes obvious. Most men quit before then — not because they lack discipline, but because nobody built a system to keep them going through the window that matters most.

Supplement Assist exists for one reason: to make sure you get rid of the issue that made you buy this in the first place.

Your 5-compound digestive protocol

What's in the Pack — and Why It's There

Gut health isn't just about probiotics. It's about microbial balance + intestinal integrity + digestive efficiency. This stack addresses all three.

20 Billion CFU

Complete Probiotic

Supports a healthy gut microbiome and promotes balanced digestive function.†

The beneficial bacteria your gut relies on to process nutrients, support immune signaling, and maintain the intestinal environment everything else depends on.

500mg

L-Glutamine

Supports the natural strength of the intestinal barrier and promotes healthy gut barrier function.†

The amino acid your intestinal cells use as their primary fuel source. Supports the structural foundation your gut needs to absorb nutrients and maintain its protective barrier.

500mg

Prebiotic Fiber

Supports healthy bowel regularity and promotes a thriving prebiotic environment.†

The prebiotic fuel that feeds the beneficial bacteria you're replenishing — because probiotics without fiber is like planting seeds without watering them.

250mg

Triphala

Supports healthy digestive motility and promotes gentle, natural cleansing pathways.†

The Ayurvedic botanical blend used for centuries to support the rhythmic movement of your digestive tract — without the harsh effects of stimulant laxatives.

250mg

Quercetin

Supports healthy intestinal barrier function and promotes a balanced inflammatory response.†

The bioflavonoid that supports the tight junctions between intestinal cells — maintaining the selective permeability your gut needs to absorb what it should and block what it shouldn't.

Why only 5? Because your gut doesn't need 15 underdosed ingredients hiding behind a proprietary blend. It needs the right 5 at doses that match published research — taken consistently for long enough to work.

Right Now, You're at a Fork.

One path is familiar. The other changes something.

Path 1 · Close this tab

Tell yourself you'll deal with it later. You've been managing fine.

Week 1

You skip the heavier option at the work dinner. Order something lighter. Again. You've been doing this for years.

Week 4

The occasional bloating is still there. You reach for something at the drugstore and move on. It's fine. It's always fine.

Month 3

You realize you haven't eaten a meal without thinking about what it'll do to you in months. That's just how it is now.

Path 2 · Start the protocol

48 hours from now, the system is live. Here's what happens.

Week 2

You almost skip. Your coaching check-in reaches out: "Gut changes take time. The microbiome needs consistency." You keep going.

Week 3

The bloating after meals starts easing. Digestion feels smoother. Less unpredictable. Something is shifting.

Day 45

You order a meal you used to avoid. You feel balanced and comfortable afterward. You order what you actually want at dinner with clients — without hesitation for the first time in years.

Day 60

First protocol you've ever finished. Your gut is working with you now, not against you. This was never about supplements — it was about rebuilding the system everything else runs through.

Jeff S., 43

Day 44

Frequently Asked Questions

How long before I notice anything?

Individual responses vary. Probiotics typically need 2–4 weeks of consistent daily use for microbiome shifts to become noticeable. Some men report less bloating within the first 1–2 weeks. The Supplement Assist coaching system helps you track subtle changes you might otherwise miss — which is why most men who stick past week 3 report meaningful differences.

What makes this different from buying probiotics on Amazon?

Nearly half of health product consumers abandon their purchase because nobody explains how to use it properly. This isn't just a probiotic — it's a 5-compound protocol addressing microbial balance, intestinal integrity, and digestive efficiency simultaneously, paired with 25 days of personalized coaching and a certified human coach who conducts a Day 21 progress review. The compounds work. The system makes sure you take them long enough for them to work.

Can I cancel anytime?

Yes. No contracts, no commitments. Cancel anytime from your account or by contacting support. We also offer a 60-day satisfaction guarantee — if you're not satisfied for any reason, full refund, even if you've opened every pack. We'd rather lose a customer than trap one.

Is this safe with my current medications?

We always recommend consulting your healthcare provider before starting any new supplement regimen, especially if you're taking medications. Our coaches provide wellness education and can discuss general timing considerations, but they are not a substitute for medical advice.

Why only 5 ingredients?

Because your gut doesn't need 15 underdosed ingredients hiding behind a proprietary blend. It needs the right compounds at meaningful doses — taken consistently for long enough to work. Every ingredient in this protocol is third-party tested, at doses that match published research, with a COA available.

What does Supplement Assist actually do?

Supplement Assist is 25 days of personalized coaching matched to your E25 Assessment scores and your specific digestive protocol. You get daily check-ins timed to your schedule, progress tracking against the gut issue that brought you here, and a certified human coach who reviews your progress at Day 21. It exists because the gap between when people quit supplements and when supplements start working is the core reason most protocols fail.

What's the difference between Subscribe and One-Time?

Both include the same 5-compound daily pack. The subscription ($69.90/mo — 16% off) also includes Supplement Assist™ coaching: 25 days of personalized daily check-ins matched to your E25 scores, plus a certified coach who conducts your Day 21 progress review. One-time purchases include the supplements only. You can cancel the subscription anytime with one click.

Your Gut Has Been Asking for Support. This Is the Answer.

5 compounds at research-referenced doses. Supplement Assist™ coaching matched to your assessment scores. A certified coach who reviews your progress at Day 21. And a 60-day guarantee that means you risk nothing.
