Stroke

A stroke is a medical emergency. If you are experiencing stroke symptoms, call emergency medical services, even if they resolve quickly. This page does not discuss acute treatments for stroke, but rather focuses on mitigating the risk of having a stroke and supporting recovery from a stroke. Lifestyle and dietary habits that keep your blood pressure, blood sugar, cholesterol levels, and your weight in check, can help to reduce the risk of stroke.

How It Works

Stroke recovery is a long process that involves rehabilitation to regain lost function. While physical therapy, occupational therapy, and speech therapy are the cornerstones of recovery, nutritional support may help optimize brain healing and reduce the risk of another stroke. The brain has remarkable plasticity—the ability to rewire itself—and proper nutrition supports this process.

CRITICAL: Stroke is a medical emergency. After stroke, medical management including blood pressure control, antiplatelet/anticoagulant therapy, statins, and rehabilitation is essential. These supplements are ADJUNCTIVE to standard medical care, not replacements. Always work with your stroke recovery team.

•Omega-3 Fatty Acids have anti-inflammatory effects and support brain health. After stroke, the brain experiences inflammation that can cause additional damage. Omega-3s may help reduce this inflammation and support the brain's repair processes. They also reduce cardiovascular risk, helping prevent another stroke.
•Citicoline (CDP-Choline) is a building block for brain cell membranes. After stroke, the brain needs to repair damaged neurons and form new connections. Citicoline provides the raw materials for this process. While large trials haven't shown dramatic acute stroke benefits, it may support longer-term recovery and cognitive function.
•Vitamin D deficiency is very common after stroke and is associated with worse outcomes. Vitamin D supports neuroprotection, immune function, and bone health (important given increased fall risk after stroke). Many stroke survivors are confined indoors during recovery, worsening deficiency.
•B Vitamins (B6, B12, Folate) lower homocysteine, an amino acid linked to stroke risk. High homocysteine damages blood vessels. B vitamin supplementation may help reduce the risk of recurrent stroke, though this is still being studied.
•CoQ10 is an antioxidant that supports mitochondrial function—the energy production machinery of cells. After stroke, brain cells are under stress and need energy to repair. CoQ10 may support this recovery process.
•Vitamin E is an antioxidant that may help protect brain cells from ongoing oxidative damage during recovery. Use moderate doses of mixed tocopherols.
•Zinc supports neuroplasticity—the brain's ability to rewire and form new connections. This is crucial for stroke recovery. Zinc deficiency can impair healing and immune function.
•Creatine supports brain energy metabolism. The brain uses enormous amounts of energy, especially when healing. Creatine may help maintain brain energy levels during recovery.
•Ginkgo Biloba improves cerebral blood flow and has antioxidant properties. It may help with cognitive recovery after stroke, particularly for problems with memory and thinking.

Expected timeline: Recovery is gradual over months to years. Supplements support this long-term process. Most improvement occurs in the first 3-6 months, but recovery continues beyond that.

Depression is a chronic state of low mood often associated with hopelessness, apathy, and fatigue. Unlike sadness, depression is a disorder that persists for weeks or months and interferes with daily life.

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.
