How this protocol works

In plain language

Postural syncope (fainting) occurs when blood pressure drops significantly upon standing, causing inadequate blood flow to the brain. This causes lightheadedness, dizziness, visual changes, and fainting when going from lying/sitting to standing. It can be caused by dehydration, medications (especially blood pressure meds), aging, diabetes, Parkinson's disease, and autonomic nervous system disorders. It's particularly common in older adults and can lead to dangerous falls.

CRITICAL: Postural syncope requires medical evaluation to identify underlying causes. Rule out heart problems, medication effects, dehydration, anemia, and neurological conditions. Treatment depends on the cause. Medications like midodrine or fludrocortisone may be needed. Compression stockings and abdominal binders help. Physical counter-maneuvers can prevent fainting. Fall prevention is essential. These supplements support blood volume and cardiovascular function but don't replace medical treatment for significant orthostatic hypotension.

Sodium and Fluid Loading* is the first-line non-pharmacological treatment. Increasing salt intake (3-5g daily) along with adequate fluids (2-3 liters) expands blood volume, reducing the blood pressure drop when standing.

Vitamin B12* deficiency can cause autonomic dysfunction leading to orthostatic hypotension. Ensuring adequate B12 levels supports nerve function.

Coenzyme Q10* supports cardiovascular function and energy production.

Iron* - anemia worsens orthostatic symptoms because there's less oxygen-carrying capacity. Correcting iron deficiency can help.

Magnesium* supports cardiovascular and nerve function.

Licorice Root* contains glycyrrhizin which has mineralocorticoid-like effects, helping retain sodium and raise blood pressure. Use with caution and monitor blood pressure.

Expected timeline: Salt and fluid loading can show benefits within days. Other interventions may take weeks to assess benefit. Management is often long-term.
