The best time of day to take folic acid tablets is usually about 1-2 hours after breakfast to facilitate the absorption of the drug. Folic acid is a water-soluble vitamin and usually works best when taken on an empty stomach. However, since folic acid is irritating to the gastrointestinal tract, taking it on an empty stomach may cause nausea, vomiting and other symptoms, so it is recommended to take it 1-2 hours after meals; secondly, the gastrointestinal function is active in the morning, which is conducive to the absorption of folic acid, so it is generally not recommended to take it at night. Folic acid tablets themselves are a kind of vitamin, and if the normal diet is nutritionally balanced, people generally do not need to take special supplements, but if you want to prepare for pregnancy, it is recommended that you can start taking folic acid in the first three months of pregnancy until the initial three months after conception. When taking folic acid, care should be taken to use other drugs with caution, and to ensure a balanced diet and avoid partial and picky eating. If you are preparing for pregnancy, you should pay attention to regular work and rest, avoid straining and staying up late, and keep a happy mood.
