Top 5 Cortisol Blockers: Reduce Stress & Improve Your Performance

While cortisol can be helpful to some degree in short bursts, chronic stress can cause cortisol levels to remain high which can lead to undesired effects such as increased inflammation, reduced immune function, and even muscle loss. To combat this, there are supplements that are designed to help lower or inhibit cortisol. 

In this blog, we will be taking a closer look at our top 5 cortisol inhibiting supplements and ranking them by their potency and effectiveness.

The Role of Cortisol

Cortisol is a hormone that plays a crucial role in the body's response to stress. It is released by the adrenal glands in response to stress, which can include anything from physical exertion or exercise to emotional stress. 

High cortisol levels can have a massive impact on your health and can lead to a number of undesirable effects such as:

• Increased inflammation
• Reduced immune function
• Muscle loss
• Increased fat storage
• Increased blood pressure
• Decreased bone density
• Insomnia
• Anxiety
• Depression

By reducing cortisol, you can help mitigate these negative effects and improve your overall health while optimizing your performance in the gym.
