Overview
THORNE's Vitamin C supplement provides 1,000 mg per serving in 60 capsules, third-party certified and free of gluten, dairy and soy, formulated for immune function and collagen formation support.
Third-party certification is the standout detail here, since it means an outside lab checks label accuracy, a step not all vitamin C products carry. At 1,000 mg per serving, this sits at a common higher-end dose for vitamin C supplements aimed at daily immune support. The listing doesn't specify how many capsules make up one serving, so whether 1,000 mg is per capsule or per multiple capsules isn't confirmed here.
- 1,000 mg vitamin C
- 60 capsules per bottle
- Third-party certified
- Gluten, dairy and soy free
Who it's for
Fits buyers who specifically want third-party certified supplements and a straightforward vitamin C product without other added ingredients. Less relevant for anyone wanting a combination immune formula with zinc or other vitamins included.
Pros and cons
- 1,000 mg vitamin C per serving
- Third-party certified for label accuracy

Performance notes
Vitamin C at gram-level doses like 1,000 mg is generally taken for immune and collagen support, and third-party certification means the capsule contents were checked against the label by an outside lab rather than the brand alone. Gluten, dairy and soy free labeling addresses common allergen concerns in capsule fillers and coatings.
