Trusted brand. Recommended by Dietician and Geneticism for hEDS.
DreamySkye—October 4, 2025
Easy to swallow. I hope it’s helping me avoid illness. Size is fine. Can’t measure the value for the money, I just trust the brand. I’m taking this dose because I have Hypermobile Ehlers Danlos and my geneticist said I needed it. Dietician said Thorne is the way to go. Can’t complain yet. Read more
