How much Immune support supplements should I take daily?

Introduction

Immune support supplements are widely used to enhance the body's defense mechanisms, particularly in populations at risk of immune dysfunction, such as the elderly and critically ill patients. This synthesis aims to provide insights into the optimal daily intake of various immune support supplements based on recent research findings.

Key Insights

Vitamin B6 Supplementation:
- High doses of vitamin B6 (50-100 mg/day) significantly improve immune responses in critically ill patients, increasing T-lymphocyte and T-helper cell numbers.
Multivitamins and Trace Minerals:
- Daily multivitamin or trace-mineral supplements, including zinc (>20 mg/day) and selenium (100 µg/day), along with additional vitamin E (200 mg/day), are recommended for elderly individuals to boost immunity and reduce infection risk.
Selenium Supplementation:
- Supplementing with selenium (50-100 µg/day) enhances immune function, increases cytokine production, and improves viral clearance in adults with marginal selenium status.
Comprehensive Micronutrient Support:
- Adequate intake of multiple micronutrients, including vitamins A, D, C, E, B6, B12, folate, zinc, iron, copper, and selenium, is essential for optimal immune function. Supplementation may be necessary to meet higher daily requirements, especially in populations with increased needs.

Conclusion

To support immune function effectively, a combination of high-dose vitamin B6 (50-100 mg/day), a daily multivitamin with zinc (>20 mg/day) and selenium (100 µg/day), and comprehensive micronutrient supplementation is recommended. These strategies are particularly beneficial for critically ill patients and elderly individuals, helping to enhance immune responses and reduce infection risks.

Vitamin B6 supplementation increases immune responses in critically ill patients

Large doses of vitamin B6 supplementation (50 or 100 mg/day) can improve immune responses in critically ill patients.

Nutritional strategies to boost immunity and prevent infection in elderly individuals.

Daily multivitamin or trace-mineral supplements with zinc, selenium, and vitamin E can boost immunity and prevent infections in elderly individuals.

An increase in selenium intake improves immune function and poliovirus handling in adults with marginal selenium status.

Increased selenium intake improves immune function and poliovirus handling in adults with marginal selenium status, suggesting that 100 micrograms/day may be insufficient for optimal function.
