Dr. Dow uses our Diurnal Cortisol test to check his adrenal stress hormone levels.

Canary Club is proud to be referenced in this new book about stress and cortisol - Heal Your Drained Brain: Naturally Relieve Anxiety, Combat Insomnia, and Balance Your Brain in Just 14 Days, by Dr. Mike Dow.


In his book Heal Your Drained Brain, Dr. Mike Dow offers a 2-week plan designed to help you naturally balance your brain. He explains what drains modern brains, which groups are wired for it, and provides clinically proven tools to help you feel less drained. Dr. Mike offers nutritional tips, recipes, cognitive behavioral tools, supplements, breathing techniques, self-hypnosis, and mindfulness. Stress hormones like cortisol and adrenaline go down as feel-good neurotransmitters like GABA and serotonin rise.

Dr. Dow also referred to Canary Club's home saliva cortisol test on his recent appearance on the Rachael Ray Show!

Our 4x cortisol tests use saliva samples collected at four times throughout the day to measure your full daily cycle. The results provided show your levels compared with the "normal" levels, revealing if you are producing a higher than average amount of stress hormones.

Find out your cortisol levels with one of our 3 focused health tests:

Diurnal Cortisol 4x Test
Measures your full daily cycle of cortisol production by collecting samples at four points during the day.

Adrenal Stress Test
Same as Diurnal Cortisol 4x, but also checks your level of DHEA-S, an adrenal hormone related to weight issues, adrenal cancer, polycystic ovary syndrome (PCOS) and masculine physical characteristics in women.

Cortisol Awakening Response (CAR)
Extra testing of your morning cortisol levels, plus the full daily cycle as in the Diurnal Cortisol 4x test. This shows how fast your cortisol rises upon waking after a night's sleep.
