  • Hyman also discusses boosting glutathione through liposomal or intravenous glutathione for acute clinical situations

Timing

  • Take with food to avoid stomach upset
  • Johnson takes NAC in the morning as part of his Blueprint stack, noting the stack should be taken earlier in the day due to energy-promoting ingredients

  • Sulfur-rich foods like garlic, onions, and cruciferous vegetables also boost glutathione production and complement NAC supplementation

Recommends for Immune Support

On the Huberman Lab channel, NAC is discussed in two episodes focused on immune health. In his cold and flu episode, Huberman identifies NAC alongside zinc as supplements showing promise in reducing cold duration and potentially preventing infections. Guest Dr. Roger Seheult discusses NAC and zinc as beneficial for supporting the immune system and reducing viral symptom severity, within a broader framework of natural health interventions including sunlight, exercise, and sleep.
