Overview
A high-dose vitamin D3 capsule, THORNE Vitamin D-10,000 delivers 10,000 IU per serving in a third-party certified, gluten, dairy and soy free formula, sold 60 capsules to a bottle for people who need a concentrated dose rather than a standard multivitamin amount.
10,000 IU sits well above the amount found in a typical daily multivitamin, which is why a dose this size is usually taken for a diagnosed low vitamin D level or under a doctor's direction rather than for general maintenance. Third-party certification matters most to athletes who need a supplement screened for banned substances. Because vitamin D is fat soluble and can accumulate in the body, a high dose like this is generally something to run past a doctor and confirm with periodic bloodwork.
- 10,000 IU vitamin D3 per capsule

Who it's for
People with a confirmed low vitamin D level or a doctor-directed high-dose plan, and athletes who want third-party certification. Not intended as a casual, general-maintenance daily dose.
Strengths and trade-offs

Performance notes
Each capsule delivers a concentrated 10,000 IU dose of vitamin D3, well past what a multivitamin provides, and the gluten, dairy and soy free formulation targets people managing food sensitivities. Third-party certification adds a layer of verification for what's actually in the capsule, relevant to athletes subject to banned-substance testing.
