I have been taking Karen Phytoplankton for about 2 years, hearing about it on Facebook. I definitely noticed my energy level increase right away. It’s helped with my joint pain and my skin looks healthier. I also have thyroid problems and since I’ve been on Karen my levels have been going down so the doctor has reduced my Synthroid medication, waiting for my next year check up hoping I could come off my medication. I also have not been sick with colds since taking Karen. Overall happier feeling.
