- 01Magnesium GlycinateModerate75% match
Magnesium influences aldosterone and sodium-potassium balance, and correcting a deficiency may modestly reduce mild premenstrual and idiopathic fluid retention.
SuggestedMagnesium glycinate, 200 to 400 mg elemental in the evening - 02Vitamin B6Moderate70% match
Vitamin B6 supports neurotransmitter and hormone metabolism and may reduce premenstrual fluid retention, possibly via effects on estrogen clearance.
SuggestedPyridoxal-5-phosphate (P5P), 25 to 50 mg daily - 03PotassiumModerate66% match
Higher potassium intake promotes natriuresis (urinary sodium loss), which can counteract sodium-driven fluid retention.
SuggestedPotassium-rich foods or low-dose potassium citrate, under clinician guidance - 04TaurineLimited60% match
Taurine has mild natriuretic effects and may support fluid balance through osmoregulation and effects on the renin-angiotensin system.
SuggestedTaurine powder or capsule, 1 to 2 g daily - 05Vitamin CLimited55% match
Vitamin C supports capillary wall integrity, which in theory may reduce fluid leakage into surrounding tissue.
SuggestedVitamin C, 500 mg daily with food
