Persevere it’s worth it
It took a few weeks for this to kick in but I’m so glad I persevered. Also customer service is great they keep you informed and actually answer emails 😁

I can say when I ran out I noticed the difference more by not taking them. When taking them you don't feel anything is happening, which really it is. This is why I'm reordering.

I read about Corti Help in the middle of the night as I lay awake again with my head full of unwelcome thoughts. Took advantage of a two for one offer with a ‘what have I got to lose’ attitude and a degree of skepticism. After a month I found I was still waking at 3am but drifting off again without needing to pick up a book or phone. Then I realised I was dreaming again after two years without that crucial deep sleep. Thankyou!

The product seems effective in reducing the 'fight or flight' type symptoms I experienced all the time. However the 'reaching out' emails are incredibly annoying, intrusive and patronising. Shame as it is a good product

Good service. Am only on the first bottle but do believe I am sleeping better. Will review again in another couple of months.Feeling less stressed.

I'm still on the fence as I've only been taking it for 2 weeks and not seeing anything different yet I'll stay the course and see if anything changes in the next week or so

Hi Steve! Thank you so much for sharing your experience and for sticking with it! Two weeks is still quite early so please do give it a little more time as most customers start feeling the benefits around the 4 to 6 week mark. If you'd like any help fine-tuning your routine in the meantime, feel free to reach out to us at [email protected] and we'll be happy to help! 🙌
