Description
"Vitamin B9" (folate) is a water-soluble nutrient abundant in leafy greens, beans, avocados, and citrus fruits, with synthetic folic acid used in fortified foods. Folate supports the creation of red and white blood cells, enhancing oxygen delivery and immune responses. Cell division and DNA formation rely heavily on sufficient folate, especially during pregnancy. By regulating homocysteine, folate directly benefits cardiovascular health. Optimal folate intake further promotes cognitive clarity and emotional resilience.

Deficiency Symptoms
A deficiency in vitamin B9 can lead to symptoms such as weakness, headaches, irritability, difficulty focusing, heart palpitations, shortness of breath, tiredness, and tongue sores.
Synergists & Antagonists
Vitamin B9 works synergistically with vitamins B2, B3, B5, B6, B12, C, and minerals like copper, iron, magnesium, and zinc to support DNA synthesis, red blood cell formation, and metabolic function. However, excess copper and aluminum may act as antagonists, interfering with vitamin B9 absorption.
