Cortisol on video, September 2026
What is Cortisol?
Cortisol is a steroid hormone made by the adrenal glands. It helps the body manage energy by raising blood sugar, plays a part in the stress response, and follows a daily rhythm that is usually highest in the morning and lowest at night. Doctors can measure it with blood, saliva or urine tests.
On social video, "cortisol" has become shorthand for stress. Creators tie it to sleep (28% of September cortisol videos), energy (19%), skin (16%) and blood sugar (13%), and they promote routines and supplements they say help, from morning light to ashwagandha and magnesium. This page reports what creators say, not what works.

What this means for marketers
Treat cortisol as evergreen
Share of wellness video moved from 1.55% in August to 1.44% in September. Cortisol is a steady vocabulary for stress, sleep and energy, not a launch-worthy spike.
Goli has the field to itself
Goli appears in 42 of 338 cortisol videos; no other brand passes 5. A stress or sleep brand can enter a conversation with almost no branded competition.
Ingredients beat brand names
Ashwagandha (65 videos) and magnesium (49) show up far more than any product. Creators search and speak in ingredients, so lead with them.
Education drives reach, shop posts drive volume
The top video is an 8.2M-view Huberman clip; Goli's TikTok Shop posts stay under 7K each. 44% of cortisol TikToks carry the sponsored flag.
Claims draw scrutiny
Promises to "drop cortisol" sit next to creators who call out cortisol-supplement marketing. Brands that describe ingredients plainly avoid the backlash.
What skeptics say
Creators pushing back on the trend, with links to each video.
