Magnesium (Citrate)
200 mgWhy we picked it: Citrate absorbs three times better than the oxide form most cheap supplements use. Relaxes the uterine muscle and softens cramp intensity inside the first cycle.

Finally something that works.
Cramps used to put me in bed for two days. After my second cycle on Happy Flow it was a few hours, if that. The cinnamon flavour is good too.
The natural formula for pain-free periods with less cramps, less bloating and less mood swings.
Tested by women, made for women. Female-owned.
Four clinically researched herbs. No fillers. No fluff.
Six ingredients. Six reasons.
We didn't pick what was trending. We picked what trials show works for cycle support, in the doses they tested. Here's why each one is in the bag.
Why we picked it: Citrate absorbs three times better than the oxide form most cheap supplements use. Relaxes the uterine muscle and softens cramp intensity inside the first cycle.
Why we picked it: P5P is the active form your body uses without conversion. Cut PMS mood and irritability scores by 69% in a 2019 trial.
Why we picked it: Calm without sedation. Smooths luteal-phase anxiety without making you drowsy or replacing your morning coffee.
Why we picked it: Methylcobalamin bypasses the genetic conversion bottleneck many Black women have with the cheaper cyanocobalamin form. Stops day-one exhaustion at the source.
Why we picked it: Powers the COMT enzyme that clears excess oestrogen. Without enough folate, oestrogen builds up. With it, your luteal phase calms down.
Why we picked it: Adrenal support. Caps the cortisol spike that makes PMS week feel like a panic week.

I built Happy Flow because I was tired of being told to push through it.
