    My Experience

    *not professional medical advice* I have taken this on and off for a few years. I originally purchased this at my neuropathy dr office. My endocrine system had began to shut down from stress, this was a game changer. Now that I am in my mid 40s I have began taking it again and this has made a huge difference for me personally. I take it along side an adrenal med.

    100% helped with long term Covid effects

    100% helped with long term Covid effects! I have had no energy brain fog loss of hair and doing some research I found that it had a lot to do with thyroid I took this he five years ago through my natural path. But she gave me so many things I had no idea which was working it which wasn’t. In the last week I have had almost 50% recovery on my energy and lack of brain fog. Also less hair in my hair brush. I have half a thyroid so obviously it wasn’t enough to keep me going now I feel like there’s a future And I don’t want to do on the couch. Thank you for this product!
