Quality sleep is one of the most important factors in pursuing and achieving your goals, whether that be recovery, fat loss, or both! The problem is that it's commonly overlooked. Just one night of poor sleep has been shown to cause an increase in the appetite-stimulating hormone ghrelin. It can also elevate cortisol levels and decrease glucose tolerance, both of which lead to poor metabolism and poor recovery.

That’s why we developed Core-21, a cortisol support supplement that can help support:

Nighttime Recovery
Healthy Cortisol Levels
Metabolic Health
Nighttime Relaxation

In today’s society, stress is everywhere. Whether this stress is mental, physical, or emotional, it increases your cortisol levels. When your cortisol levels remain elevated, it signals your body to hold onto fat in your midsection, and can affect the ability to recover from workouts. It can also lead to chronic lethargy and tiredness. This is where a natural cortisol support supplement can help support balanced stress, fat loss, and proper recovery.

As a nighttime cortisol support supplement, Core-21 can help support restful sleep and healthy stress levels. Deep sleep can help naturally balance cortisol and encourage better recovery. Sleep also plays a critical role in optimal metabolism.

Our cortisol support supplement, Core-21, also includes a blend of key digestive enzymes designed to support overnight digestion and nutrient assimilation.

For maximum results, Core-21 can also be paired with the 1-Db Overdrive (for Men) or 1-Db Goddess (for Women) Weight Loss Systems.

Support natural cortisol reduction and nighttime relaxation with Core-21.*
