Key Benefits of THORNE Vitamin D3

Vitamin D3 is not just another nutrient—it's essential for strong bones, a healthy immune system, and overall vitality. THORNE Vitamin D3 delivers 1000 IU per softgel to help keep your body in top shape. Here's what it supports:

• Bone and Teeth Health: Vitamin D3 enhances calcium absorption, which helps maintain strong bones and teeth.*

Each softgel contains 1000 IU of pure vitamin D3 in a base of medium-chain triglycerides (MCT oil) for optimal absorption—best taken with a meal containing fat to maximise uptake.

Who Should Consider Supplementing with Vitamin D3?

Certain groups are at higher risk for vitamin D deficiency. If you spend most of your time indoors, live in southern latitudes (like much of Australia), have darker skin, or are over 60, you may benefit from supplementation. Additionally, individuals following a vegan or vegetarian diet should note that THORNE Vitamin D3 is derived from lanolin (sheep's wool), so it's not suitable for vegans, but it's a highly pure source. Always consult your healthcare practitioner to determine your optimal dosage based on blood tests.

Understanding Vitamin D3 and D2

There are two main forms of vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D2 comes from plant sources, while D3 is naturally produced in human skin and also found in animal sources like lanolin. Research indicates that D3 is more effective at raising and maintaining blood levels of vitamin D. THORNE uses the superior D3 form, ensuring you get the most bioavailable option for supporting your health.*

Why Take a Vitamin D3 Supplement?

Vitamin D is often called the "sunshine vitamin" because your skin produces it when exposed to sunlight. However, many Australians have insufficient levels due to indoor lifestyles, sunscreen use, and latitude. Supplementing with vitamin D3 is an effective way to maintain healthy levels year-round. THORNE Vitamin D3 provides 1000 IU per softgel, which helps support bone density, immune function, and overall wellbeing.*

How Much Vitamin D3 Do You Need?

The recommended dietary intake (RDI) for vitamin D varies by age, but many experts suggest 600–800 IU daily for maintenance, with higher doses for those with a deficiency. THORNE's 1000 IU per serving provides a moderate yet effective amount for most adults. The tolerable upper intake level (UL) is 4000 IU per day, so this product fits well within safe boundaries. For personalised advise, work with a healthcare professional to check your levels.
