    Posted by iHerb Customer on Jan 02, 2018 | Verified Purchase

    After ordering this product on 12th of December and the date today is the 3rd of January, I still have not received this product yet. I am very disappointed as I am waiting for this product to start another phase of the GAPS diet which I'm am currently on and it has thrown the process of the diet out of order. I will in the future being looking to source this product from somewhere else.

    Our Daily "Happy Pills"

    Posted by iHerb Customer on Dec 29, 2017 | Verified Purchase

    My wife and I were both on Prescription Anti-Depressant Medications a couple of decades ago. At some point in time we had a look at all the side effects we were actually experiencing from taking these medications. We chose to make several lifestyle changes wrt. Nutrition and exercise. To this we added 5-Htp. After a few years we came across the Thorne brand and haven't looked back since

    Thanks for your feedback!
