Purchased thorne vitamin c locally. was going to refill on amazon. can the manufacturer thorne simply state whether ingredients are from china or not?

Dan, one of the reasons I buy Thorne is because the brand is highly recommended by Dr. Andrew Huberman from Standford Med. The ingredients are not from China. Headquaters are in NYC and manufacturing is in South Carolina. Hope that helps.

Is this NSF certified?

There is nothing on the label that says NSF Certified.

Ascorbic acid? so sourced from China?

The container does not specify where it is manufactured.

What are the capsules made of?

Hypromellose – also known as hydroxypropyl methylcellulose – is used to make Thorne's vegetarian capsules. Most of the HPMC Thorne uses to make their vegetarian capsules is naturally derived from wood pulp. In addition, Thorne’s vegetarian capsules are organic compliant, non-GMO, Kosher and Halal certified, vegan, and hypoallergenic.
