Folic Acid in Older Adults

In the natural aging process, the body undergoes a series of changes that can affect the health and well-being of older adults. In this context, the importance of adequate nutrition takes on a fundamental role in maintaining a good quality of life and preventing chronic diseases. A vitamin that plays a key role in the well-being of older adults is folic acid. In this article, we will explore what folic acid is, why it is essential for older adults, and how they can incorporate it into their diets to maintain an active and healthy life.

What is folic acid?

Folic acid, also known as vitamin B9 or folate, is a water-soluble B complex vitamin that plays a crucial role in various biological functions. It is essential for DNA synthesis, the formation of red and white blood cells, amino acid metabolism and the correct function of the central nervous system. The term “folate” is derived from the Latin “folium,” meaning “leaf,” as this vitamin is found abundantly in green foods and foliate vegetables.

Functions of folic acid in older adults

  1. Maintaining cardiovascular health:
    • Folic acid plays a crucial role in reducing levels of homocysteine, an amino acid associated with an increased risk of cardiovascular disease. As we age, the risk of heart disease increases, and maintaining optimal levels of folic acid can help reduce this possibility.
  2. Prevention of anemia:
    • Adequate red blood cell production is essential to avoid anemia, a common condition among older adults. Folic acid is essential for the formation and maturation of red blood cells, which helps prevent megaloblastic anemia, characterized by large, immature red blood cells.
  3. Cognitive health:
    • Aging is associated with a higher incidence of cognitive and neurodegenerative disorders, such as dementia and Alzheimer’s. Studies have suggested that adequate folic acid intake may help improve cognitive function and reduce the risk of these disorders.
  4. Immune system support:
    • The immune system weakens with age, increasing susceptibility to infections and diseases. Folic acid plays an essential role in strengthening the immune system, which can help older adults stay healthier and more resistant to disease.
  5. Bone health promotion:
    • As we age, bones tend to become more brittle and susceptible to fractures. Folic acid, along with other vitamins and minerals, contributes to the maintenance of strong and healthy bones.

Food sources of folic acid

Fortunately, folic acid is found in a wide variety of foods, making it easy to incorporate into the diet of older adults. Some of the richest sources of this vitamin include:

  1. Leafy greens: Spinach, chard, broccoli, lettuce, and kale are excellent sources of folic acid and other essential nutrients.
  2. Legumes: Beans, chickpeas and lentils are rich in folic acid, protein and fiber.
  3. Fortified cereals: Many breakfast cereals are fortified with folic acid to increase their nutritional value.
  4. Avocado: In addition to being a source of healthy fats, it also provides folic acid.
  5. Citrus fruits: Oranges, lemons, limes and grapefruits are rich in this vitamin and vitamin C.
  6. Liver: Beef and poultry liver is a concentrated source of folic acid, but should be consumed in moderation due to its cholesterol content.

Dosage recommendations

The recommended daily amount of folic acid for older adults varies by country and health institutions. However, in general, it is suggested that older adults consume about 400 to 600 micrograms (mcg) of folic acid per day. Some healthcare professionals may recommend a higher dose for those who have particular needs or deficiencies.

Folic acid supplementation

In some cases, older adults may not be able to get enough folic acid from their diet due to absorption problems or insufficient dietary intake. In such situations, folic acid supplements may be an option recommended by a health professional.

It is important to note that while folic acid is beneficial for health, excessive consumption of folic acid supplements can mask vitamin B12 deficiencies, which can have serious health consequences. Therefore, it is always advisable to consult with a doctor before starting any supplementation.


Folic acid is an essential vitamin that plays a vital role in the well-being and health of older adults. Its ability to maintain a healthy heart, prevent anemia, promote optimal cognitive function, and strengthen the immune system makes it a crucial nutrient for this stage of life. By including a variety of foods rich in folic acid in their daily diet, older adults can enjoy an active, healthy life, enriched by the benefits of this powerful vitamin. However, it is always advisable to consult a health professional before making significant changes to your diet or consuming supplements. With the right support, older adults can age gracefully and optimistically, maintaining a good quality of life throughout their lives.
