Strongest Oil of Oregano supplement?

Intention: Antibacterial. I have used Gaia in the past and prefer them over 'North American Herbs and Spice".

Gaia claims 35mg Carvacrol per capsule but Micro Ingredients is claiming 82.5mg Carvacrol per capsule. Can Micro Ingredients really be 2x stronger? I know Gaia is using Co2 to extract their own herbal extracts but I feel Micro is outsourcing and just a marketing company.

Anyone try them both to compare?
