    Thyroid is Back in Line!

    My massage therapist touched a spot on my foot that hurt; she told me something was wrong with my thyroid. Bloodwork confirmed. I didn't want to take prescription drugs, so tried Parsley Health's Thyroid Balance. That spot on my foot doesn't hurt anymore and my hair quit falling out! It's a fantastic product and keeps us away from Big Pharma's clutches!

    Worked for me

    My thyroid numbers were up, I took this for a few months, and things were back on my last bloodwork results.

    Thyroid Balance

    So far I’m pleased with the supplement. I stopped taking my Synthroid with proper medical direction and started taking Thyroid Balance. 4 weeks out and I have yet to experience any symptoms of having hypothyroidism.
