What is Thorne Vitamin D?
Thorne Vitamin D is a dietary supplement providing 5,000 IU of Vitamin D3 in each small, easy-to-absorb gel capsule. As a fat-soluble vitamin, D3 requires an oil suspension, which Thorne’s product delivers in a liquid in a softgel form.
Thorne Vitamin D is manufactured by Thorne Research, a U.S. based supplement company known for their exceptionally pure, potent nutritional products. Thorne’s vitamin D uses D3 rather than D2, which studies show is the preferable form with greater bioavailability and efficacy in raising blood levels.
Who Should Take Thorne Vitamin D?
Thorne Vitamin D can benefit certain individuals who need supplemental vitamin D to meet their recommended daily intake, which may include the following groups.
- Older adults over 50 at higher deficiency risk
- People with digestive disorders impacting nutrient absorption
- Those with limited sun exposure due to climate, skin tone, or lifestyle
- Athletes and active individuals needing extra for performance
- Anyone identified with a vitamin D insufficiency or deficiency
How Does Thorne Vitamin D3 Compare to Vitamin D2?
Thorne Vitamin D uses the D3 form (cholecalciferol) rather than D2 (ergocalciferol). Research shows D3 raises blood levels more effectively as it has a chemical structure closer to the D3 our skin naturally produces. D2 also requires conversion to usable D3 by the liver and is more prone to degradation. So Vitamin D3 more directly boosts levels. Unless deficient in D2 specifically, D3 is preferred.
Is Thorne Vitamin D Vegetarian?
No, Thorne Vitamin D3 is not vegetarian or vegan friendly. As a fat-soluble vitamin, D3 requires an oil for absorption, so Thorne uses a softgel capsule made of gelatin for delivery. Vegans can opt for a lanolin-sourced D3 supplement for a plant-based alternative.
Is Thorne Vitamin D Good?
Yes, Thorne Vitamin D is widely regarded by experts as an exceptional vitamin D supplement. It uses the evidence-backed D3 form and provides it in the recommended highly absorbable oil format. On Amazon, the Vitamin D has a 4.8 average review and a 4.5 average review on their website.
Thorne’s stringent manufacturing standards and purity testing ensure maximum potency and stability. The high 5,000 IU dosage also facilitates quickly restoring vitamin D levels when deficient.
How Does Thorne Vitamin D Rate With Consumers?
Based on online reviews, Thorne Vitamin D is highly rated by most consumers. They praise the pure formula, noticeable benefits for deficiencies, and Thorne’s brand reputation. Some note the high price but say the quality is worth it long-term.
A few reviews mention large pills being hard to swallow. Overall, customer sentiment indicates Thorne Vitamin D delivers excellent results for improving and maintaining D levels.
What Do Independent Thorne Vitamin D Reviews Say?
Trustworthy supplement rating sites consistently rank Thorne Vitamin D as one of the top vitamin D products. It earns high marks for the bioactive D3 form, the oil-based softgels for enhanced absorption, and Thorne’s stringent purity testing.
Many reviews cite Thorne’s stellar reputation for quality assurance within the supplement industry. Critical reviewers mainly take issue with the premium pricing, while acknowledging the formula itself is excellent.
What Does Thorne Vitamin D Taste Like?
Thorne Vitamin D softgels will not have any evident taste when swallowed, since the liquid vitamin D3 oil inside has no flavor. The softgel outer shell also masks any taste.
Some vitamins or oils can have mild aftertastes, but consumer reviews don’t mention this being an issue with Thorne’s D3 capsules. Overall, they can be taken without any unpleasant vitamin flavor.

How Fast Does Thorne Vitamin D Work?
With daily use, Thorne Vitamin D can start raising vitamin D blood levels within the first 1-2 weeks. However, it can take 2-3 months to fully replenish vitamin D stored in the body’s tissues to optimal status above 30 ng/ml.
Once restored, continued Thorne Vitamin D supplementation helps maintain healthy levels long-term. Those severely deficient may need prescription strength dosing.
When Will I Feel the Effects of Thorne Vitamin D?
Some positive effects like improved mood and immunity may become noticeable within several weeks of starting Thorne Vitamin D. However, the full effects for bone health, muscle function, and chronic disease risk reduction build over time.
