Orthostatic Hypotension
Orthostatic hypotension is a sudden drop of blood pressure when changing positions (sitting to standing). When changing positions, people may feel dizziness, heart palpitations, or lose consciousness.

Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
Expands blood volume to help maintain blood pressure when standing
Deficiency causes autonomic neuropathy; correction may improve orthostatic symptoms
Supporting Stack (Tier 2)
Vasoconstrictor that can raise blood pressure; helps prevent postprandial hypotension
Contains glycyrrhizin which raises blood pressure by increasing sodium retention
Anemia worsens orthostatic hypotension; correct if deficient
Deficiency associated with cardiovascular dysfunction; supports overall health
Supports cardiovascular function and energy production
How It Works
Orthostatic hypotension (OH) is a significant drop in blood pressure when standing up - defined as a decrease of at least 20 mmHg systolic or 10 mmHg diastolic within 3 minutes of standing. This causes symptoms like lightheadedness, dizziness, blurred vision, weakness, fatigue, nausea, and fainting. OH is common in older adults and can result from dehydration, medications (especially blood pressure drugs, diuretics), autonomic nervous system disorders (diabetes, Parkinson's), prolonged bed rest, or various medical conditions.
CRITICAL: Orthostatic hypotension requires medical evaluation to identify the cause. Medication review is essential - many drugs cause or worsen OH (BP medications, diuretics, antidepressants, alpha-blockers for prostate). Underlying conditions (diabetes, Parkinson's disease, pure autonomic failure) need to be addressed. First-line treatment is non-pharmacological: adequate fluids and salt, compression garments, slow position changes, elevated head of bed. Medications (fludrocortisone, midodrine) may be needed for refractory cases. These supplements support blood pressure but are NOT replacements for comprehensive medical management.
* Electrolytes/Sodium - Increasing salt intake (with adequate fluids) expands blood volume and is the cornerstone of OH management. Target 2-4g extra sodium daily with 2-3L of fluid.
* Vitamin B12 deficiency can cause autonomic neuropathy leading to OH. Levels should be checked and corrected.
* Caffeine is a vasoconstrictor and can help raise blood pressure, especially helpful with meals (postprandial hypotension).
* Licorice Root contains glycyrrhizin which causes sodium retention and raises blood pressure. Use cautiously and monitor potassium - prolonged use can cause problems.
* Iron - Anemia worsens orthostatic hypotension. If hemoglobin is low, correcting anemia often helps symptoms.
* Vitamin D, Magnesium, and CoQ10 support overall cardiovascular function.
Expected timeline: Salt/fluid loading provides rapid improvement (days). Caffeine effects are acute (same meal). Correcting B12 or iron deficiency takes weeks to months. Chronic OH often requires ongoing management.
