I didnt have a WOW after gelatin, but a slightly better sleep and skin;yes. Sleep also better in the summertime or when at sunny vacations. The winters up here are pretty dark, thats probably why I can notice the difference as marked as I do
I take DE only now and then as it dries me up if I take it regularly. I have to take it in the morning, as taken late disrupted my sleep terribly. Awake and a pounding heart!
I take some nettlepowder for my silica.
