Nutripak Thyroid contains Piperine?

I purchased some nutripak thyroid and when reading the ingredients I noticed that it contained piperine. Doing a cursory search I came across information that it may possibly suppress thyroid function. I am not certain if the amount is significant but what are your thoughts on this?

Nutri-Pak Natural Thyroid contains the following:

Supplement Facts: Serving Size 1 tablet, Servings per Container 90
Thyroid Tissue 130 mg
Other Ingredients: Dicalcium Phosphate, Vegetable Stearate, Pharmaceutical Glaze, Piperine
This is a GLUTEN FREE product
