Managing cortisol levels through supplementation can be an effective method for dealing with stress and adrenal hormone imbalances. Here are a few supplements that have been shown to help regulate cortisol levels:

1. Ashwagandha

   • Ashwagandha has been widely studied for its stress-reducing properties. It has been shown to significantly reduce cortisol levels and improve perceived stress and anxiety¹². It is commonly used in doses ranging from 250 mg to 600 mg per day.

2. Vitamin C

   • Vitamin C is a powerful antioxidant that has been found to lower cortisol levels. Studies indicate that supplementation with 1000 mg of vitamin C daily can significantly reduce cortisol in both stressed individuals and athletes following intense physical activity³⁴.

3. Vitamin D

   • Although not as extensively studied for its impact on cortisol as ashwagandha or vitamin C, vitamin D has been shown to reduce cortisol levels and improve stress-related symptoms, especially in the context of chronic stress⁵.
