Aging impairs immune function, and older adults often lack essential water-soluble vitamins. Supplementing with B vitamins (B1-B12) and vitamin C may support immunity and reduce infection risk in the elderly.
Area of Science:
- Gerontology
- Immunology
- Nutrition Science
Background:
- Aging leads to immunosenescence and inflammaging, increasing infection susceptibility.
- Older adults face risks of inadequate micronutrient intake, including water-soluble vitamins.
- Suboptimal vitamin levels can negatively impact elderly immune function.
Purpose of the Study:
- To review the immunomodulatory effects of water-soluble vitamins in individuals aged 65 and older.
- To focus on the roles of B vitamins (B1-B12) and vitamin C in aging immunity.
- To assess current knowledge on vitamin status and immune function in the elderly.
Main Methods:
- Comprehensive review of human, animal, and in vitro studies.
- Analysis of the relationship between water-soluble vitamin status and immune parameters in older adults.
- Comparison of dietary reference values for investigated vitamins.
Main Results:
- Both aging and low water-soluble vitamin levels correlate with immune decline and inflammation.
- Adequate intake of B vitamins (B1-B12) and vitamin C may mitigate age-related immune changes.
- These vitamins support immune cell metabolism and reduce infection susceptibility.
Conclusions:
- Water-soluble vitamins play a crucial role in maintaining immune function during aging.
- Dietary intake and supplementation are potential strategies to counteract age-related immune alterations.
- Further research, especially randomized controlled trials, is needed to confirm these effects.
