So I'm finishing my first week of Glucorein PCOS, and so far I've noticed a few positives right away:
My hair is falling out a lot less. Like, it used to clog the drain every time I showered, and now I barely see any hair in drain after a shower.
I'm craving food less and feeling hungry less. I feel more in control over what I eat, not just getting hungry and desperate to eat the first carb that comes across my eyeline.
For those TTC (sorry if it's TMI), my CM has increased and looks to be of a much healthier consistency.

So far, no significant weight loss, and if I don't eat every two hours, my blood sugar feels too low. However, I talked to one of the service reps at Napa Valley Nutritionals (the company that sells the supplement), and they've encouraged me to take the drink with meals instead of before eating, and to try to eat every two hours to keep my blood sugar steady.

The way this apparently works is that it sends food to a more distal part of the intestine to be digested, causing a much slower release of sugars into the bloodstream. This might be causing lows in blood sugar as I'm exercising quite intensely and maybe underestimating the amount of carbs my body needs to accomplish this, so I actually had to up my carb intake and I feel better and have more energy and stamina at my workouts.

Anyways, just wanted to give an update to any who are interested!
