How it works

Why cramps hit so hard — and what French pine bark does about it.

The real reason

Why it still hurts when your tests look “normal”

On day one, prostaglandins tell the uterus to contract. In some women it squeezes so hard it pinches its own blood supply — so the muscle cramps without enough oxygen. Like a calf cramp that won’t let go.

RelaxedBlood flows in, oxygen gets through.
Day one, squeezedThe cramp pinches its own blood supply.

That’s why the heating pad is the only thing that sort of works: heat opens up blood flow. But only while it’s on.

Illustration, simplified. Doppler ultrasound studies show higher blood-flow resistance to the uterus in women with painful periods (Dmitrović 2000, Altunyurt 2005).

A first in period care

Meet French pine bark — the ingredient no period brand uses.

Pycnogenol® is a patented, standardized extract from the bark of the French maritime pine, grown in the Landes forest of southwest France. It’s been researched for healthy circulation for years — it just never made it into period care. Cramp Relief is the first period cramp supplement built around it.*

  • 100 mg Pycnogenol® per serving

  • Supports healthy blood flow*

    Helps blood vessels relax via nitric oxide — what heat does from the outside, from the inside.

  • Calms the cramp signal*

    Inhibited COX-1 and COX-2, the enzymes that make prostaglandins.

In a double-blind, placebo-controlled trial, women with painful periods who took pine bark needed less painkiller medication, on fewer days.*Suzuki et al., J Reprod Med 2008. No significant difference in women with mild pain.

Made for women who…

  • Get mild to moderate period cramps most months

  • Are 18+ and not pregnant, trying to conceive or breastfeeding

  • Have come off the pill — or never wanted to start

Talk to your doctor first if you take blood thinners, have a bleeding disorder or surgery coming up, take blood-pressure or diabetes medication — or if your pain is severe or getting worse.

What to expect

What to expect, honestly.

  1. Cycle 1

    You’re building it up. Some women notice a difference right away — many don’t yet.

  2. Cycle 2

    In the pine bark study, the benefit grew over time. This is where most women start to notice.*

  3. Cycle 3

    The full routine. In the study, the benefit even held after women stopped.*

Individual results vary. Not a painkiller and not a miracle — a daily routine that supports an easier period.
