This supplement works great for lowering high cortisol. One capsule should be taken at night, when cortisol is supposed to be lowest. By lowering the cortisol, melatonin is able to increase on its own, like it's supposed to. This supplement only works for sleep if high cortisol is what is keeping you awake. If your cortisol is low, it's not for you. For those with high cortisol, it often reduces anxiety and also improves bowel function. Just be aware that high cortisol is sometimes because of an underlying inflammatory issue. If that is the case, lowering cortisol with this supplement may cause a flare up in inflammatory symptoms.
I really like the combination of ingredients in this product. I actually came across this when I was looking at a product with identical ingredients at a much more expensive price. This product is high quality, excellent ingredients and much more affordable.
