What the research says
Backed by published research on probiotics and women's health.
Below is what published nutritional research says about the strain families and probiotics in this formula.
-
Organic Inulin Powder (as Agave tequilana) supports healthy gut motility + relief from pregnancy-related constipation†
A double-blind RCT in the European Journal of Clinical Nutrition found inulin supplementation (5–10 g/day) significantly increased stool frequency + softness in pregnant women experiencing constipation — one of the most common GI complaints in pregnancy. Inulin also acts as a prebiotic, selectively feeding Bifidobacterium strains in the probiotic blend.†
-
Bacillus subtilis (BS31) supports healthy gut microbiome stability + immune function during pregnancy†
Bacillus subtilis is a spore-forming probiotic with exceptional stability at room temperature, making it ideal for no-refrigeration formulas. A clinical study in Beneficial Microbes found B. subtilis supplementation significantly improved gut microbiome diversity + reduced pathogenic bacteria colonization in pregnant women, supporting maternal immune balance.†
-
Vitamin B6 (as Pyridoxal 5-Phosphate) supports reduction of pregnancy-related nausea + healthy fetal brain development†
A systematic review in Obstetrics + Gynecology confirmed Vitamin B6 (10–25 mg doses) significantly reduces nausea + vomiting in early pregnancy and is recommended as a first-line intervention. The bioactive P-5-P form bypasses hepatic conversion, delivering superior bioavailability vs. pyridoxine HCl — particularly important during the first trimester when nausea is most severe.†
-
Infant gut microbiome is shaped by maternal flora at birth and through breastfeeding.†
A 2018 review in Nature Medicine and subsequent studies describe how vaginally-born and breastfed infants acquire their initial gut microbiome from the mother, with Bifidobacterium and Lactobacillus species dominant in healthy infant guts during the first months of life.†

From Amy, Founder + CEO
Gut health was something nobody talked about during my own pregnancies, and looking back, I wish I'd known. This is the probiotic I take alongside my prenatal, and the one we built for the women who ask us, every week, what to do about pregnancy constipation, recurrent yeast, or how to give their baby the best start. Six strains, a real prebiotic, OBGYN-reviewed.

Why Pink Stork
What we believe, and what we won't compromise on.
We've spent a decade saying no to the shortcuts the rest of the supplement industry says yes to. Here's the standard we hold ourselves to, in plain English.
-
Strains you can name.
Every probiotic strain in the bottle is named on the panel by genus and species, so you know exactly which strain families you're taking.
-
Real CFU on the label.
The CFU count on the panel reflects what's in the bottle at expiration, not just at the time of manufacture.
-
Third-party tested every batch.
Independent labs verify strain identity, CFU count, and that heavy metals stay within recognized safety thresholds, every lot, before it ships.
-
Expert-Panel Reviewed, doctor-reviewed.
Built and reviewed by our OBGYN-Led Council. Real doctors with real practices and real patients, not paid spokespeople.
-
Independent and woman-owned.
Still independent. Not owned by Unilever or Nestlé. Not for sale. Accountable to the women who take our products, not to investors waiting on an exit.
-
Built on faith, family, and a better standard for moms.
Founded a decade ago by Amy, a mom who couldn't find supplements she trusted, and built them. She still owns Pink Stork. She still runs it. And she still takes them every single day.
Real women, real results
Over a million women. Still counting.
