Folate (vitamin B9) is critical for DNA and RNA synthesis, cell division, and red blood cell formation. Adequate folate is especially important before and during early pregnancy to prevent neural tube defects. Deficiency can cause megaloblastic anemia, fatigue, and elevated homocysteine levels. People on certain medications, those with malabsorption conditions, and heavy alcohol users are at higher risk.
Vitamin and nutrient testing identifies deficiencies that can drive fatigue, immune dysfunction, neurological symptoms, and long-term disease risk — and confirms that supplementation is working.
Anyone with restrictive diets (vegan, low-fat, low-carb), malabsorption conditions, fatigue, hair loss, mood changes, or currently supplementing and wanting to verify dosing.
