I did a search on the internet on this product and I came accross a web site that stated that the only ingredient in cortisol blockers that has any effect is called "Phosphatidylserine". And that if you were going to take it you would be you would need about 800 mg a day for it to have any effect. But you can buy a product with just "Phosphatidylserine" and nothing else. But to take 800 mg a day it would be expensive. Most cortisol blockers that I have seen only contain 8.3mg of this ingredient.
