Source Naturals Vitamin D3 2000 IU - 200 Capsules

Who Needs Vitamin D Supplementation?

Some individuals are more prone to insufficient vitamin D levels. Those with limited exposure to sunlight—due to working indoors, living in northern climates, or using sunscreen—may require supplementation. People with darker skin tones produce less vitamin D from sunlight, and older adults have reduced synthesis efficiency. Vegans should be aware that the vitamin D3 in this product is derived from lanolin (sheep's wool), making it unsuitable for a vegan diet. Always consider your dietary preferences.

Key Benefits of Vitamin D Supplementation

Vitamin D plays a role in several bodily functions. It contributes to the normal absorption and utilisation of calcium and phosphorus, which are important for maintaining strong bones. It also supports normal muscle function, which can benefit balance and mobility, particularly in older adults. Additionally, it contributes to the normal functioning of the immune system.

Understanding Vitamin D3 vs. D2

Vitamin D exists in two primary forms: D2 (ergocalciferol) from plants and D3 (cholecalciferol) from animal sources, typically lanolin from sheep's wool. Research suggests that D3 is more effective at raising and sustaining blood levels of vitamin D. Therefore, Source Naturals use D3—the form your body naturally produces. Each capsule contains 50 mcg (2000 IU) of vitamin D3, a potent yet safe daily maintenance dose.

Recommended Dosage and Usage

The UK government recommends a daily intake of 10 mcg (400 IU) of vitamin D during autumn and winter. However, many people may benefit from higher amounts for optimal blood levels. This product provides 50 mcg (2000 IU) per capsule—a common maintenance dose. Take one capsule daily with a meal, as vitamin D is fat-soluble and best absorbed with dietary fat. If you are taking medication or have health concerns, consult your GP before use.

Safety and Considerations

Vitamin D is safe at recommended intakes. However, taking very high doses over prolonged periods can lead to toxicity. Do not exceed the recommended dose unless advised by a health care professional. If you have a medical condition such as hypercalcaemia or kidney stones, consult your doctor before use. Keep out of reach of children.

The Importance of Vitamin D3

Often referred to as the 'sunshine vitamin', vitamin D is produced by the body when skin is exposed to sunlight. Many people do not receive enough sunlight, especially during winter or in northern latitudes. Supplementation can help maintain adequate levels. Source Naturals Vitamin D3 provides cholecalciferol, the same form your body produces naturally. This bioactive form supports calcium absorption and other functions crucial for health.
