Why Measure Cortisol?

Cortisol is your body’s primary stress hormone, produced by the adrenal glands. In a healthy cycle, cortisol peaks shortly after waking and declines throughout the day. Imbalances can contribute to symptoms like:

• Low energy or burnout

• Anxiety, depression, or irritability

• Difficulty falling or staying asleep

• Unexplained weight changes

• Hormone imbalances or menstrual irregularities

Why Choose Saliva Testing?

Unlike blood tests, saliva testing reflects the bioavailable (active) hormones—not those bound to proteins. ZRT’s advanced testing delivers accurate insights into your real-time hormone activity with the convenience of at-home collection.

• No need to stop hormone supplementation
