cijenom proizvoda sam zadovoljna. stvarno djeluje na apetit,tj. smanjuje ga. morala sam nakon nekoliko dana prekinuti piti jel sam imala problema sa grčevima u želudcu.

Enteric coating is a huge plus

Posted by Reviewer2776030 on Sep 02, 2016

I usually take 100mg and my only complaint is that Thompson's don't make this in that strength, not available on i herb at least. The quality however is excellent and for anyone with sensitive tummy the enteric coating is a huge plus. It does help if constipation is an issue, and it does help with sleep. I will always use 5htp and will probably use this brand on and off with my stronger dose. It is very cost efficient for a product that actually works... many don't our have negative effects on me.

I took this since I heard it increases your deep sleep phase. It may happen, but I did not feel much.
