What other supplements can help with flu?

To help with flu symptoms, Andrew Huberman mentions several supplements and practices that can be beneficial:

1. N-Acetylcysteine (NAC): This supplement has shown a significant reduction in influenza risk in studies, with only 25% of those taking it contracting the virus compared to 79% in the placebo group. NAC can increase glutathione levels, which supports overall health and might help shorten the duration of colds or flu. The typical dosage mentioned is 1200 mg per day, divided into two doses of 600 mg each 1 Andrew Huberman.

2. Vitamin D: Supplementing with 1000 to 2000 IU of vitamin D daily is generally considered safe and can help maintain an adequate level to support immune function. However, precise amounts should be determined by measuring your vitamin D levels, as some individuals may require higher doses 2.

3. Other Considerations: Zinc, already mentioned, is effective in shortening colds and potentially flu duration when taken at proper dosages. Additionally, ensuring good sunlight exposure and maintaining gut health through diet are recommended practices for overall immune support.

Echinacea is also discussed but is considered less effective in scientific studies for either cold or flu prevention. It may potentially weaken the immune system if taken in high doses over long periods 3.

As always, be sure to consult with a healthcare professional before starting any new supplement regimen, especially when considering dosages and potential interactions with other treatments.
