• Supplements to boost immune system

  • Sources:

    Here are some supplements that mentions can support the immune system:

    1. Vitamin D: Supplementing with 1000 to 2000 IU daily is generally safe and can help maintain adequate vitamin D levels, which is important for immune function. Higher doses may be needed for some individuals, but testing is essential to avoid overdosing 1.

    2. Zinc: This mineral is effective in combating colds, particularly if you take 100 mg or more. It's important to take zinc with food to prevent gastric distress 2.

    3. Glutamine: An essential amino acid that can bolster the immune system by increasing the number of killer cells. It can be consumed in supplement form or from glutamine-rich foods like cottage cheese 3.

    4. Echinacea: Though popular, echinacea may not significantly prevent colds or flu and could potentially weaken innate immune functions if taken in high doses. It should be used sparingly and not for long durations 2.

    It's essential to consult with a healthcare provider before starting any supplement regimen, particularly in cases of pre-existing health conditions or when considering high doses.
