Tag: Cancer and folic acid

According to the Centers for Disease Control and Prevention (CDC), sufficient folic acid intake can prevent up to 70% of neural tube defects, yet persistent advice against taking it circulates widely. The reasons behind this skepticism range from misunderstanding the difference between natural folate and synthetic folic acid to concerns about high-dose side effects and potential risks for specific health conditions. This article clarifies why these cautions are raised and separates substantiated concerns from widespread myths.

According to the Office on Women's Health, taking more than 1,000 micrograms of folic acid per day can hide the signs of a vitamin B12 deficiency, potentially leading to irreversible nerve damage. While this synthetic vitamin is vital in preventing birth defects, understanding what is bad with folic acid is crucial for informed supplementation.

While folic acid is widely known for its role in preventing birth defects and supporting cell growth, certain medical conditions and circumstances make supplementation risky. It is critical to understand who should avoid taking folic acid to prevent serious health complications, such as masking a dangerous vitamin B12 deficiency.
