Postural Syncope
Postural syncope refers to a sudden drop in blood pressure due to a quick change in position, such as from lying down to standing. It can be caused by dehydration and certain medications. Symptoms may include lightheadedness or dizziness, blurry vision, and fainting.

Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
Increases blood volume through fluid retention; reduces orthostatic symptoms
Deficiency can cause orthostatic hypotension; essential for autonomic nerve function
Supporting Stack (Tier 2)
Supports cardiovascular function and cellular energy production
Anemia worsens orthostatic symptoms; correct if deficient
Contains glycyrrhizin which raises blood pressure through mineralocorticoid effects
How It Works
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.

This goal refers to people with a BMI >25 attempting to reach/maintain their ideal weight. While interventions that work for people with a BMI >25 may also work for people with a lower BMI, the context is often sufficiently different that this isn't assured.
Type 2 Diabetes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.
