We source our materials globally, including the United States, China and others.

There is a misconception that countries such as China have regulations that are less strict. They actually are more stringent in certain cases. More importantly, raw materials are thoroughly globalized and as such need to be produced to high standards. As a further step in maintaining quality, all material is tested to verify source materials are indeed what they claim to be.

Manufacturing of the final product is in the United States and follows all cGMP processes for identity and purity controls, which is then 3rd party tested.

Maximum potency is 2 years from the “MFG” (manufacture) date, or until the “EXP” (expiration) date, typically 2 years after it has been manufactured. However many supplements remain viable for years after.

This is available only for certain countries, such as Canada or Australia. Please review the available methods at checkout for any option that says “DDP”. If there is none showing then it is not available for your region.
