THORNE Vitamin D-10,000 - High Potency Vitamin D3 Supplement - Supports Bone, Teeth & Immune Health - 60 Capsules

Key Benefits of Vitamin D3

Vitamin D plays a crucial role in several bodily functions. It contributes to the normal absorption and utilisation of calcium and phosphorus, which is essential for maintaining healthy bones and teeth. It also supports normal muscle function and the normal function of the immune system.*

• Bone and Teeth Health: By enhancing calcium absorption, vitamin D helps maintain strong bones and teeth throughout life.*
• Immune Function: Vitamin D modulates immune responses, supporting the body's natural defences.*
• Muscle Function: Adequate vitamin D levels contribute to normal muscle function, particularly important for active individuals.*

Who May Benefit from 10,000 IU Vitamin D3?

Many people struggle to get enough vitamin D from sun exposure alone, especially those living in northern latitudes, older adults, individuals with darker skin tones, or those who spend most of their time indoors. Vitamin D deficiency is common, and a high-potency supplement like Thorne Vitamin D-10,000 can help bridge the gap. Athletes and active individuals may also benefit from maintaining adequate levels for muscle function and recovery.*

Vitamin D3 vs D2: Why D3 is Superior

Vitamin D3 (cholecalciferol) is the form naturally produced in human skin upon sun exposure and is found in animal-based foods. Vitamin D2 (ergocalciferol) comes from plant sources. Research indicates that D3 is more effective at raising and maintaining vitamin D levels in the blood. For this reason, most experts recommend D3 supplementation. Thorne uses only D3 for maximal benefit.

How Vitamin D Supports Immune Health

Vitamin D receptors are present on many immune cells, indicating its role in regulating immune responses. Adequate vitamin D levels are associated with a lower risk of respiratory infections and may help modulate inflammation.* By including Thorne Vitamin D-10,000 in your daily routine, you can help ensure your immune system has the support it needs.

How to Choose a Quality Vitamin D Supplement

Not all vitamin D supplements are created equal. Thorne's formula uses the highly absorbable D3 form and undergoes rigorous third-party testing to ensure accuracy and purity. The supplement is free from common allergens and artificial additives. Thorne is a trusted brand recommended by health care practitioners and used by over 100 professional sports teams.

What Makes THORNE Vitamin D-10,000 Different?

With 10,000 IU of vitamin D3 (cholecalciferol) per capsule, this high-potency supplement is designed for individuals who need extra support to maintain optimal vitamin D levels. Vitamin D3 is the preferred form because it is more bio-available than vitamin D2 — research shows it is more effective at raising and sustaining blood levels.* Thorne's Vitamin D-10,000 is third-party certified, meaning every batch is tested to confirm purity and potency. It is also free from gluten, dairy, and soya, making it suitable for many dietary needs.

Recommended Dosage and Usage

Each capsule provides 10,000 IU (250 mcg) of vitamin D3. As a fat-soluble vitamin, it is best absorbed when taken with a meal containing fat. Typical maintenance dosage for adults may range from 600 to 2,000 IU daily, but higher doses like 10,000 IU are often used under the guidance of a health care professional to correct deficiency. Always consult with your health care provider before starting any new supplement regimen.

Safety and Considerations

Vitamin D is generally safe when taken as directed. However, extremely high doses over prolonged periods can lead to toxicity. The tolerable upper intake level for adults is 4,000 IU per day from all sources, but short-term uses of 10,000 IU is often considered safe under medical supervision. If you are pregnant, nursing, or taking medications, discuss with your doctor before uses.
