What the research says
Backed by published nutritional research.†
Below is what published nutritional research says about the ingredients in this formula.
-
Supports the body's natural menstrual cycle†
According to Strowitzki et al. in a randomized, double-blind, placebo-controlled trial, women receiving Vitex agnus-castus experienced normalization of shortened luteal phases and elimination of deficits in luteal progesterone synthesis, changes that were significant and occurred only in the treatment group, not placebo.†
-
Supports the body's natural progesterone levels during the luteal phase†
According to Milewicz et al., in a randomized placebo-controlled double-blind study of 52 women, Vitex agnus-castus supplementation was associated with reduced prolactin release and measurable improvements in mid-luteal progesterone synthesis within three months of daily use.†

Supports menstrual cycle wellness†
According to Tóth et al., in a retrospective longitudinal cohort study of 1,700 women with menstrual cycle disorders, three months of Vitex agnus-castus extract reduced the percentage of women experiencing irregular cycles from 9.1% to 0.1%.†
-
Supports emotional wellness and comfort during the premenstrual phase†
According to Cerqueira et al., a systematic review of eight randomized controlled trials found that all eight studies reported positive outcomes for Vitex agnus-castus in women with PMS.†

From Amy, Founder + CEO
Pink Stork started because I couldn't find a supplement I trusted for my own pregnancy. Every formula since has been built with our OBGYN-led medical council, third-party tested, and made with the bioavailable forms, Methylated Folate, Chelated Iron, Algae DHA, my own kids deserve. We're still independent, still woman-owned, and still run by me. I take this every day.

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.
-
Bioavailable forms, every single time.
Methylfolate over folic acid. Chelated Iron over ferrous sulfate. Methylcobalamin over cyanocobalamin. We pay more so your body can actually use what's on the label.
-
Real ingredients. Real names. Real forms.
Every ingredient is named on the panel, in its bioavailable form. No anonymous 'special blends' designed to hide what's actually in the bottle.
-
Third-party tested every batch.
Independent labs verify potency, label accuracy, heavy metals, and microbes, every lot, before it ships.
-
Expert-Panel Reviewed, doctor-reviewed.
Built and reviewed by our six-person, OBGYN-led medical advisory 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.
