a fan of Wentz
I’m a big fan of Isabella Wentz. Having Hashimoto’s Disease, I’m always on the lookout for supplements that won’t aggravate my auto-immune condition. Wentz, who specializes in Hashimoto’s, has done a great job creating products specifically for people with this disease.

Good
Product is good so far. It doesn’t have a foul odor as some reviews of other products suggest. It doesn’t cause stomach upset either. I will have a stronger opinion after taking it for a month or so. In my opinion it will take time to build up the immune system.

Great product
Excellent product, I bought as a supplement for Hashimotos and it’s helpful warding off coughs as well… no unpleasant smells as others have reviewed. I’m keeping this one in my daily protocol.

Thyroid Peroxidase Antibodies
I’ve been struggling with Hashimoto’s thyroiditis since 2005 and so I’ve tried several products, dietary and lifestyle changes to help lower my thyroid peroxidase antibodies (TPO). Most of them didn’t yield any results except for this one combined with Rootcology betaine, Rootcology adrenal support and Enzymedica Lacto Digestive Enzymes After trying this for 3 months, I’m happy to report that my thyroid peroxidase antibodies went down by 25% since my last blood tests 3 months ago. I feel much more energized and this feels great.

Izabella Wentz’s Rootcology line is specifically designed for those with autoimmune conditions (mine is Hashimoto’s Hypothyroidism). I feel a remarkable difference in my energy throughout the day. I feel like my concentration is much more focused. I will be buying this again!
