Introduction
The differences between folic acid and composite folic acid include variations in composition, nutritional benefits, target populations, recommended dosages, and usage scenarios. Selection should be based on individual needs. Individuals with specific health conditions or who are planning pregnancy should seek medical advice for professional guidance. Folic acid contains only a single folic acid component and is a water-soluble B-vitamin.

The differences between folic acid and complex folic acid include variations in composition, nutritional benefits, target populations, recommended dosages, and usage scenarios. Selection should be based on individual needs. Individuals with specific health conditions or who are planning pregnancy should seek medical advice promptly for professional guidance.

1. Different Composition: Folic acid contains only a single ingredient—folic acid—which is a water-soluble B-vitamin. Complex folic acid includes folic acid as well as additional nutrients such as iron, other B-complex vitamins, and vitamin D, offering a more comprehensive formulation.

2. Different Nutritional Benefits: The primary role of folic acid is to prevent fetal neural tube defects and improve megaloblastic anemia. In addition to these core benefits, complex folic acid also provides various essential micronutrients, meeting broader nutritional needs.

3. Different Target Populations: Folic acid is suitable for individuals who simply need to increase their folic acid intake, such as women planning pregnancy or those with folic acid deficiency. Complex folic acid is better suited for women who are planning pregnancy, pregnant, or suffering from malnutrition, as it offers a one-stop solution for multiple nutrients essential during pregnancy.

4. Different Dosages: The typical dosage for folic acid supplements is 0.8 mg per tablet, sufficient for basic supplementation. In complex folic acid products, the folic acid content is usually also 0.8 mg, combined with appropriate amounts of other nutrients to avoid excessive intake of any single component.

5. Different Usage Scenarios: Folic acid can be used as a standalone daily supplement with flexible duration. Complex folic acid is more suitable for continuous use from preconception through lactation, providing comprehensive nutritional support for both maternal health and fetal development.

Folic acid or complex folic acid supplementation should follow recommended dosages to avoid blind overuse. Products should be purchased through reputable channels and stored in a cool, dry place. A balanced diet should be maintained during supplementation to promote nutrient absorption and overall health.

What is lacking in megaloblastic anemia?
Folic acid is a key component in DNA synthesis during red blood cell production. Deficiency impairs the division and maturation of red blood cells, leading to the formation of abnormally large but dysfunctional megaloblasts. Folate-deficiency megaloblastic anemia may result from insufficient intake of fresh vegetables in the daily diet, improper cooking methods (such as excessive boiling that destroys folic acid), or malabsorption due to intestinal disorders.

Can folic acid and iron tablets be taken together?
Folic acid and iron tablets can be taken together. Taking them in combination is not only safe but also enhances each other's absorption, making it especially suitable for individuals who are planning pregnancy, pregnant women, and those with iron-deficiency anemia. If severe gastrointestinal discomfort or allergic reactions occur after taking them, medical attention should be sought promptly. Folic acid itself does not interfere with iron absorption and can help improve anemia symptoms by participating in red blood cell synthesis.

Why do I feel dizzy after taking Ornidazole capsules?
A lower than normal number of red blood cells or hemoglobin levels in the body leads to insufficient oxygen and blood supply to the brain. Taking ornidazole capsules may worsen dizziness. This condition is often accompanied by symptoms such as pale complexion and fatigue. Under a doctor's guidance, patients can take ferrous sulfate tablets, folic acid tablets, and vitamin B12 tablets, and consume more iron- and protein-rich foods.

Can folic acid and fluoxetine be taken together?
Folic acid is a water-soluble vitamin primarily used to prevent fetal neural tube defects and to treat megaloblastic anemia and other types of anemia. Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) antidepressant that improves mood by modulating neurotransmitters in the brain. Since their mechanisms of action are different, taking them together usually does not produce toxic side effects or exacerbate adverse reactions.

Are expensive and cheap folic acid supplements equally effective?
The core effects of expensive and inexpensive folic acid are the same. As long as they meet national standards and contain adequate amounts of the active ingredient—folic acid—their effectiveness in preventing folic acid deficiency and supporting fetal neural tube development is identical. If you experience allergic reactions or have specific health concerns after taking it, seek medical advice promptly. Inexpensive folic acid products are typically basic formulations with simple compositions, containing only folic acid or a small amount of essential vitamins.

What should I eat after receiving ovulation stimulation injections to support follicle development?
During the period of receiving ovulation stimulation injections, it is beneficial to consume more foods rich in protein, folic acid, vitamin D, zinc, and omega-3 fatty acids, as these nutrients support follicle development by providing adequate nourishment and help promote follicular maturation and ovulation. If gastrointestinal discomfort occurs after dietary adjustments or if you have any underlying medical conditions, it is recommended to seek medical advice promptly.
