Supplements to boost immune function against cold

To boost immune function against colds, Andrew Huberman suggests several supplements based on current scientific evidence:

1. Zinc: Supplementing with 100 milligrams or more of zinc can combat colds effectively. Lower doses (<75 mg) are ineffective, and it's important to take zinc with food to avoid gastric distress 1.

2. Vitamin D: Generally, 1000 to 2000 IU per day is considered safe and beneficial for immune support. People with deficiencies might need higher doses, but it's essential to get blood levels checked to avoid overdosing 2.

3. N-Acetylcysteine (NAC): This supplement is a precursor to glutathione, a major antioxidant that reduces oxidative stress during infections, potentially aiding the immune system 3.

4. Vitamin C: High doses (6,000 to 8,000 mg per day) might help, but the evidence isn't robust, and such high amounts can cause gastric distress for many people 4.

Other key strategies include maintaining adequate sleep, regular exercise, managing stress, and proper nutrition to support the immune system 5.
