For business travelers
Terminal B — hour 5 of a 14-hour delay

You know the moment.

Five hours in. Gate B47. The board flipped from delayed to canceled to rebooked twice. There's no fridge. There's no water fountain that inspires trust. There's a 12-hour flight ahead, then a hotel room with a mini-fridge full of $18 sparkling water and no vegetables in sight.

Your gut is going to feel this trip whether you address it or not. You know from the last three trips that day three is the hard one — the bloat, the sluggishness, the low-grade feeling that your body is running two hours behind local time even after you've adjusted.

You've done the airport pharmacy tour. The probiotic bottles say "refrigerate for best results" in small print. You've watched roommates chew a chalky ginger tablet at 3 AM in Prague. You've packed a Seed pouch and forgotten it in your other backpack. You've bought a 30-count Culturelle and taken 3 doses before losing track.

What you actually need is not another bottle. Not another routine. What you need is one thing you can throw in a wallet, that doesn't care about temperature, that gets absorbed in 30 seconds under your tongue, and that gives you the same 10 billion CFU on day 12 of a trip that it gave you on day 1.

There's a specific reason capsules keep failing on trips — and a specific way to change it.
How it works

Why sublingual + prebiotic beats a fridge-only capsule.

The delivery route is the whole story. Here's the biology, in plain terms.

01

Why capsule probiotics die in airport life

Standard probiotic capsules dissolve in your stomach — where hydrochloric acid destroys a significant portion of live bacteria before they reach the gut. That's why premium brands ship on ice packs and tell you to refrigerate. Heat + acid = fewer surviving strains.

02

Sublingual delivery bypasses the acid bath

A sublingual strip dissolves under your tongue in ~30 seconds. The Bifidobacterium lactis strain absorbs directly through the mucosal tissue — skipping the harsh stomach environment. No refrigeration required because the strip's pullulan base is shelf-stable at room temperature.

03

The polydextrose prebiotic feeds the strain once it lands

Bifidobacterium lactis needs a food source to establish. Polydextrose (50 mg per strip) is a soluble fiber that Bifido preferentially ferments — giving the strain fuel to colonize once it reaches the gut. This is why our formulation is called Probiotic + Metabolism, not just Probiotic.

Peer-reviewed researchBeneficial Microbes · 2016

Bifidobacterium animalis subsp. lactis HN019 supplementation in adults with functional gastrointestinal symptoms

In a randomized double-blind trial of 90 adults, B. lactis supplementation for 14 days significantly improved digestive comfort scores versus placebo. Whole-gut transit time decreased by an average of 12 hours in the active group.
B. lactis HN019 was associated with statistically significant improvements in defecation frequency and reduced feelings of incomplete evacuation compared to placebo.
Honest limitation: The study population was symptomatic adults, not healthy travelers specifically. Effects may vary in asymptomatic individuals. Also note: B. lactis is one of several strains under the Bifidobacterium umbrella — results are strain-specific.

The format

THE XYNE STRIP

Three layers. Thirty seconds. Straight to the bloodstream.

01
The outer film
A plant-based pullulan film — the strip's structural layer. Same material used in dissolvable vitamin strips. Melts on contact with saliva.
02
Where the ingredients live
Active ingredients are suspended in microscopic capsules across the middle sheet. Each capsule delivers a precise, uniform dose — every strip contains the same amount as every other.
03
The dissolution layer
The base film carries natural humectants that trigger rapid disintegration under your tongue. Full absorption through the sublingual mucosa in about 30 seconds — skips the stomach entirely.

The product

Built for the way you actually travel.

Xyne Probiotic + Metabolism Strips are what happens when a probiotic is designed around the travel routine instead of the pharmacy shelf. One strip a day. Room temperature. No excuses.

  • 10 billion CFU that don't need a fridge
    Bifidobacterium lactis is one of the most-studied probiotic strains for digestive comfort. Sublingual delivery skips the stomach acid environment that reduces the viability of capsule probiotics.
  • Polydextrose prebiotic in the same strip
    50 mg of soluble fiber that Bifidobacterium lactis preferentially ferments — so the strain has fuel to establish once it lands, not just a delivery.
  • Wallet-sized tin, 30-day supply
    One tin covers a full month of travel. TSA-friendly, no liquid, no gel, no refrigeration. Ships every 30 days on subscription — skip a month before a long trip if you overlap.
30-day money-back — keep the tin.
Head-to-head

Xyne vs. Seed
vs. Culturelle.

Honest comparison — Seed has more strains.

Why formats matter
Culturelle is cheaper. Where Xyne wins is the travel scenario: no fridge, sublingual delivery, wallet-sized tin.

Common questions

Travelers' top
10 questions.

In the order business travelers actually ask them — storage first, then TSA, then how-to.

Do I need to refrigerate this?

No. Xyne Probiotic + Metabolism Strips are shelf-stable at room temperature. This is one of the main reasons the sublingual format works for travel — you can leave a tin in a hotel drawer for two weeks without losing potency. Standard probiotic capsules often need refrigeration to keep the bacteria viable.

Is it TSA-safe?

Yes. Not a liquid, not a gel. The tin is smaller than a deck of cards. Fits in a wallet, a passport case, or a laptop bag. Traveled through TSA countless times without a question. Not restricted in international customs either.

How do I take it?

Peel back the seal. Slide the strip under your tongue. Let it sit for 20-30 seconds. Don't chew, don't swallow, don't move it around. No water needed. Best taken in the morning with breakfast, but any time of day works.

What's the refund policy?

30-day money-back guarantee. Keep the tin — no return needed. Email inquireall@xyne.health or use the contact form. We refund without requiring you to ship anything back.

What will this actually do for me?

Support gut microbiome balance — especially during travel, dietary changes, or after antibiotic use. Bifidobacterium lactis is one of the most-studied probiotic strains for supporting digestive comfort. Most customers describe it as their gut being "quieter" on trips — less bloating, less unpredictability. This is not a laxative and is not a cure for any condition.

Are there side effects?

Bifidobacterium lactis is generally well-tolerated. Some customers report mild gas or bloating in the first 3-5 days as the gut adjusts — this typically resolves. If you have a compromised immune system, are on immunosuppressants, or have a serious GI condition, consult your doctor before starting.

Can I take this with my medication?

If you're taking antibiotics, take Xyne Probiotic Strip at least 2 hours away from your antibiotic dose so the probiotic bacteria have time to establish. Consult your doctor if you take immunosuppressants or are immunocompromised. No known interactions with common travel medications (Dramamine, jet lag prescriptions, etc.).

Can I skip a month of my subscription during a long trip?

Yes — one click from your account. You can pause, skip, or cancel any time. Some subscribers skip a month before a long trip to overlap tins, others just add an extra tin on demand. No email required, no phone call.

How fast does it ship?

All orders ship in 2 business days, then standard delivery (free) takes 3-7 business days. Ships from a US warehouse.

Is this FDA-approved?

Supplements aren't FDA-approved — that's a category rule, not a Xyne thing. We ARE manufactured at an FDA-registered cGMP facility specializing in sublingual delivery, and every batch is third-party tested. Certificates of Analysis available on request.

What if it doesn't work for me?

30-day money-back guarantee — keep the tin, no return needed. Email us at inquireall@xyne.health. We'd love to hear why so we can improve, but the refund isn't conditional on that. Some people don't feel probiotics acutely — they work on baseline. If you're not feeling any difference after 30 days, it's the right time to try something else.
