I took these supplements consistently for over two months, but unfortunately didn’t notice any changes personally. That said, I’m glad they work well for others, and perhaps I simply need a different kind of support. I reached out about a refund and the customer service team was helpful and processed it without any issues.

Good communication, sound advice given. Have noticed a calmer brain at bedtime.

I’ve used this product for a month now and don’t feel any different. I’m not sure I want to persist, either. Firstly, the cheap packaging that my bottles arrived in gave me little faith in the product. I was unsure if I wanted to even start taking the stuff. When I enquired about the manufacturing process, the company was vague and couldn’t give a straight answer. “Business is based in USA but products are made in Asia”. Where in Asia?? The company claims everything is lab tested but no disclosure of what labs are used or certifications provided. I don’t think this is transparent at all. I don’t care to know where operations are based. I want to know where the country of origin is for a product I’m putting in to my body. Is that so much to ask?

Ordered the midnight offer which was the buy one get one free, but if ordered before midnight would get a further 2 bottles for the same price. Only 2 bottles arrived. In questioning they refuse to accept this was the offer I ordered. And cleverly enough the email makes it look this way also. So feel like I have been totally scammed by this.

Ive had the best sleep since taking these no more waking at 2am then not being able to sleep I'm around 3 weeks in and if I do wake up I can get back to sleep again no tossing or turning will continue to take these. Delivery took around 2 weeks so order early if restocking
