Expiration date : 3 years
Been using it for some days now in this lock down, I'm totally surprised by it's effectiveness! Honestly I never had any bloated feeling or sugar rushing feeling after taking it and a big meal, and my stomach never had a bad feeling even if I take it empty-stomach.
Good product, I'm ordering more.
By the way it's one small bag of 5 pills per time before you are going to eat a lot. It doesn't work for whole day.
