- 01IronStrong82% match
Iron deficiency and anemia reduce oxygen-carrying capacity and can drive lightheadedness on standing, so repletion addresses a common underlying cause.
SuggestedFerrous bisglycinate, 25 to 65 mg elemental every other day with vitamin C - 02Vitamin B12Moderate76% match
B12 deficiency can cause anemia and autonomic dysfunction, both of which may contribute to orthostatic symptoms.
SuggestedMethylcobalamin, 1000 mcg daily (sublingual or oral) - 03PotassiumLimited64% match
Adequate potassium alongside sodium and fluids supports blood volume and electrolyte balance that help stabilize standing blood pressure.
SuggestedPotassium-rich foods, paired with adequate salt and fluid intake - 04Magnesium GlycinateLimited57% match
Magnesium supports autonomic and vascular function, and correcting deficiency may help overall cardiovascular regulation.
SuggestedMagnesium glycinate, 200 to 300 mg in the evening - 05Vitamin CLimited56% match
Vitamin C enhances non-heme iron absorption and supports vascular collagen, mainly aiding orthostatic symptoms indirectly through iron status.
SuggestedVitamin C, 250 to 500 mg taken with iron-containing meals - 06L-TyrosineLimited55% match
Tyrosine is a precursor to norepinephrine, which raises vascular tone, so it is theorized to support blood pressure in orthostatic intolerance.
SuggestedL-tyrosine, 500 to 1000 mg in the morning on an empty stomach
