Kelp pills not in store mailed to me.
This is the first I have used this product and so I don't have any results. I am taking this Kelp to increase my iodine in my system.

Great for Thyroid issues!
I was diagnosed with Thyroid cancer in 2012 which led to the removal of my entire Thyroid gland. I take my meds as directed and still felt fatigued, no energy, overly emotional and constantly cold. Within 3 days of taking the Kelp, I feel "normal" after suffering for years. Thank you GNC for giving me my life back!
