Four well-characterised probiotic strains and a prebiotic to feed them — chosen for the year your body is doing the most and being asked about the least.
Try Renú todayEvery organism is named on the label, with its strain designation. Here's what each one is doing once it gets there.
The most-studied name in the category, and one of the organisms that naturally colonises the small intestine. It helps support a healthy balance of gut bacteria — the population that pregnancy, birth, and any course of antibiotics can disrupt.*
A workhorse further down the tract, where regularity and comfort are decided. Bifidobacteria are among the first organisms to establish in the human gut, and among the first to thin out under stress.*
Probiotics are living things, and living things need to eat. FOS is a plant-derived fibre chain your body doesn't digest — it passes through intact and feeds the beneficial bacteria you just took, along with the ones already living there.*
Stomach acid kills most of what you swallow. This marine-derived carrier is designed to shield the cultures through that stretch, so more of the 40 billion you paid for arrives where it can actually do something.*
Also included: Lactobacillus plantarum (Lp-115) and Lactobacillus paracasei (Lpc-37), which round out the blend across the length of the digestive tract.*
Four things a multi-strain probiotic and prebiotic can support while you recover.
Beneficial strains help support your body's natural defenses through a physically demanding stretch.
Supports healthy digestion and regular bowel movements, and helps reduce occasional bloating.
A settled gut is the ground everything else grows from — including how the middle of the day feels.
Helps replenish beneficial bacteria after pregnancy, birth, antibiotics, and hormonal change.
Built around four named strains and a prebiotic to feed them.
DigestionSupports healthy digestion, regularity, and less occasional bloating.*
Bloating and irregularity are the two complaints moms raise most in the first postpartum year, and they are also the two a probiotic is best placed to address. Bifidobacterium lactis (Bl-04) works further down the tract where regularity is decided, while the fructooligosaccharide feeds the population already living there. Most people who notice a change report it somewhere in the second to fourth week.*
DistensionHelps ease the tight, distended feeling after eating.*
That tight, stretched feeling across the middle — where your waistband sits differently by evening than it did that morning — is one of the most common complaints after birth. A multi-strain probiotic with a prebiotic to feed it supports the bacteria involved in normal fermentation and gas production, which is what drives that occasional distended feeling in the first place.*
ImmunitySupports your body’s natural defenses through recovery.*
A large share of immune activity happens in and around the gut lining, which is part of why gut balance and immune function get discussed together. The weeks after birth are physically demanding and short on sleep. Beneficial strains help support your natural defenses.*
BalanceHelps replenish beneficial bacteria after birth and antibiotics.*
Pregnancy, delivery, hormonal change, and any course of antibiotics all reshape the gut microbiome — often faster than it rebuilds on its own. A multi-strain formula reintroduces beneficial organisms across the length of the digestive tract rather than a single point in it, which is why there are four here and not one.*
RegularitySupports bowel movements that feel more predictable day to day.*
Slower, less predictable digestion is one of the most common shifts after birth, and hormonal change, iron supplementation, and disrupted sleep all feed into it. Bifidobacterium lactis (Bl-04) settles further down the tract where regularity is decided, and the fructooligosaccharide feeds the population already living there. Regularity is usually the first thing moms mention noticing.*
Postpartum wellnessBuilt for the stretch after birth, not borrowed from a general formula.*
The strains here were chosen for the year your body is doing the most and being asked about the least. Nothing in the formula requires refrigeration, the capsule is vegan, and the dose is two capsules a day — because a supplement you have to plan around is one you stop taking.*
Renú is a daily habit, not a quick fix. A gut microbiome shifts over weeks, not overnight, and anyone promising you a result by Friday is selling you something else. Here is an honest picture of the range — including the weeks where nothing happens.
Start your first bottleIndividual experiences vary. These are ranges reported by people taking a daily multi-strain probiotic, not outcomes we can promise you.*
Four strains, each printed with its exact designation — La-14, Bl-04, Lp-115, Lpc-37 — alongside the prebiotic and the marine polysaccharide carrier at their stated amounts. Bring the label to your OB or midwife and there is nothing for them to guess at.
Most brands print the CFU count measured at bottling, which is the flattering number. Ours is guaranteed through the end of the printed shelf life — so the bottle you finish in week four is doing what the bottle you opened in week one did.*
Not a general gut formula with a pink label. Two capsules, split morning and evening, no refrigeration, and a size that fits next to the kettle. Designed around a day that has no schedule in it and a person with no spare attention.

A bottle lasts 30 days. Most moms find the second month is when they stop thinking about it and it just becomes part of the morning.
