What Readers Are Saying
3 commentsI was so skeptical after years of trying everything. But 3 months in and I've lost 22 lbs. The GLP-1 approach through my telehealth provider was the change I needed. Wish I'd found this a year ago.

My doctor mentioned I was a candidate for GLP-1 but the cost through insurance was prohibitive. Found a telehealth option for under $200/month which is a game-changer.

Frequently Asked Questions
What are the best supplements for sleep?
The most evidence-backed sleep supplements include magnesium glycinate (200-400mg), melatonin (0.5-3mg), L-theanine (100-400mg), and glycine (3g). However, sleep quality depends on multiple factors — stress, circadian alignment, and cellular energy all play a role.
How does cortisol affect sleep?
Elevated cortisol levels — particularly at night — directly interfere with sleep quality. Cortisol follows a diurnal rhythm, peaking in the morning and dropping at night. Chronic stress disrupts this rhythm, making it difficult to fall asleep and stay asleep.
