Withanly · Probiotic 40 Billion with Prebiotics

You finished antibiotics
two weeks ago.
Your gut still hasn't.

60 delayed-release vegan capsules · 40 billion CFU · 6 strains + prebiotic

Maybe it was antibiotics. Maybe it was a holiday where the food disagreed with you. Maybe it's just that the bloat after meals has been sticking around longer than it used to. One capsule a day, 40 billion live cultures, six strains, and a prebiotic to feed them — in a capsule built to survive stomach acid instead of dying on the way through. Most probiotics never actually arrive.

Bloating I'd lived with for years just quietly went away.

The formula

Six things to know about what's in the bottle.

  • Black pepper for absorption
  • Vegan pullulan capsule
  • Third-party tested
  • No fillers or flow agents
  • Bottled in the USA, GMP-certified

A quieter system

Three ways the shift shows up.

Actually makes it past your stomach.

Delivery

Actually makes it past your stomach.

Most probiotic capsules are corpses by the time they reach the gut. Delayed-release shells get the live cultures where they're supposed to do their work.

Bloat that quietly stops happening.

Comfort

Bloat that quietly stops happening.

The post-meal heaviness, the irregular week, the rumble at the worst moment — the six strains in here are the families gut-health research keeps coming back to.

Fewer of the colds your kid brought home.

Immune

Fewer of the colds your kid brought home.

Around 70% of your immune system sits in your gut. The healthier the floor down there, the less every winter cough turns into your weekend off.

You're just self-diagnosing here mate. L. Acidophilus is a known probiotic and a normal inhabitant of the human gut. AFAIK probiotic species also usually don't even colonize the gut but just pass through. I'm not saying you aren't suffering, but L. Acidophilus is probably not the reason. You probably just have a dysbiotic gut generally. Restoring balance and diversity is more important than trying to kill off individual species in your gut.

Apr 28 Your stomach is a vat of hydrochloric acid designed to melt foreign microbes. Most probiotics die there, but Bacillus clausii survives by wearing built-in biological armor. The fundamental difference between Bacillus clausii and Lactobacillus lies in their life cycles and cellular structures. Lactobacillus species are vegetative bacteria. They are biologically active but highly vulnerable to environmental stressors like heat, time, and gastric acid. Because of this fragility, many Lactobacillus products require refrigeration to keep the microorganisms viable, and a significant percentage of the

I suspect you might not be consistently eating the right foods for feeding/maintaining your L. rhamnosus culture. Sauerkraut, kefir, & kimchi would probably be good options, as well as yogurt. A variety of these every day of the week would help establish the culture.

I have been taking Pure GG (25 billion l. rhamnosus) for about a month and it has been hugely helpful for me. I have mcas, pots, heds and cfs (or my cfs is a combo of the aforementioned)

Honest answers

Questions you actually asked

Why 40 billion CFU?

The research on digestive-comfort endpoints clusters around 10–50 billion CFU. We chose 40 billion as a defensible mid-range — meaningful colonisation potential, without the unnecessary cost-loading of 100B+ formulas that lack additional research backing.

Why six strains?

Different strains carry different evidence profiles. Lactobacillus covers digestive transit; Bifidobacterium covers regularity; the rest broaden microbiome diversity. Six is the research-supported sweet spot.

Does it need refrigeration?

No. The delayed-release capsule and strain selection are stable at room temperature. Refrigeration is fine and extends shelf life but is not required.

How quickly will I notice anything?

Most people describe a digestive baseline shift in 7–14 days. The deeper microbiome rebalancing builds over 8–12 weeks of consistent use.

Should I take it with food?

Ideally before food in the morning, with water. The empty stomach is the easiest transit path; food slows transit and exposes the capsule to acid for longer.

Will I get bloating when I start?

Some people notice mild gas the first 3–5 days as the microbiome adjusts. This typically resolves on its own. If it persists past a week, halve the dose to one capsule every other day.

Can I take it with antibiotics?

Take the probiotic 2–3 hours after the antibiotic dose. Many physicians recommend probiotic use during and after a course of antibiotics — talk to yours for specific guidance.

Is it safe during pregnancy or breastfeeding?

Most probiotics are considered safe during pregnancy and breastfeeding, but talk to your physician before starting any new supplement during this period.

What if it doesn't work for me?

Email contact@withanly.com within 30 days of delivery and we'll refund the full amount — you don't need to send the bottles back.

How fast does it ship?

From our US warehouse, USPS Ground typically arrives in 2–4 business days within the contiguous US.
