| Vitamin D Immune Meta-Analysis | In addition, vitamin D has been linked to reduced susceptibility to respiratory infections, attenuation of airway inflammation, and potential modulation of airway remodeling, all of which are relevant to asthma exacerbation and long-term disease control (,,,). | 1 | Liu Yongxiu (2026) | Efficacy and safety of vitamin D in the treatment of asthma: an overview of systematic reviews and meta-analyses |
| Vitamin D Immune Meta-Analysis | Therefore, a higher-level synthesis of the existing evidence is needed to critically examine its reliability, consistency, and certainty. | 1 | Liu Yongxiu (2026) | Efficacy and safety of vitamin D in the treatment of asthma: an overview of systematic reviews and meta-analyses |
| Vitamin D Immune Meta-Analysis | In addition, the optimal supplementation dose, whether the benefits are mainly restricted to individuals with baseline vitamin D deficiency, and the long-term efficacy and safety of vitamin D supplementation remain uncertain and require further validation in high-quality evidence-based studies (,). | 1 | Liu Yongxiu (2026) | Efficacy and safety of vitamin D in the treatment of asthma: an overview of systematic reviews and meta-analyses |

| Vitamin D Immune Meta-Analysis | These immunological changes significantly contribute to increased morbidity, mortality, and healthcare costs among older adults (). | 1 | Li Die (2026) | Effects of micronutrient supplementation on immune function in older adults: a meta-analysis |
| Vitamin D Immune Meta-Analysis | Furthermore, immunosenescence is exacerbated by poor nutrition, particularly micronutrient deficiencies, which are common in the elderly due to reduced food intake, metabolic changes, and disease (). | 1 | Li Die (2026) | Effects of micronutrient supplementation on immune function in older adults: a meta-analysis |
| Vitamin D Immune Meta-Analysis | Deficiencies in these nutrients have been linked to weakened immune function, elevated inflammation, and increased susceptibility to diseases (–). | 1 | Li Die (2026) | Effects of micronutrient supplementation on immune function in older adults: a meta-analysis |
| Vitamin D Immune Meta-Analysis | 1 2 3 4 5 Immunosenescence is the gradual deterioration of the immune system that occurs with biological aging (). | 1 | Li Die (2026) | Effects of micronutrient supplementation on immune function in older adults: a meta-analysis |
