What Makes Vitamin D3 Special?

Vitamin D exists in two main forms: D2 (ergocalciferol) and D3 (cholecalciferol). Research indicates that D3 is more effective at raising and maintaining blood levels of vitamin D. D3 is the form your body naturally produces when exposed to sunlight, making it the preferred choice for supplementation. Source Naturals use vitamin D3 to maximise bioavailability and efficacy. As a fat-soluble vitamin, it is best absorbed when taken with a meal containing fat. The liquid drop format allows you to easily mix it into a drink or take it directly, ensuring consistent support for your body’s needs.

Key Benefits of Vitamin D3 Supplementation

  • Bone Health: Vitamin D helps your body absorb calcium and phosphorus, minerals vital for maintaining strong bones and teeth. It plays a key role in bone mineralisation and supports bone density.*
  • Immune Function: Vitamin D supports the normal functioning of the immune system, helping your body defend against seasonal challenges.*
  • Muscle Strength: Adequate vitamin D levels help maintain muscle strength, particularly in older adults, supporting mobility and reducing the risk of falls.*
  • Calcium Absorption: By promoting calcium absorption in the gut, vitamin D ensures that your body can effectively use dietary calcium.*

Who Should Consider Taking Vitamin D3?

Certain individuals may be at higher risk of low vitamin D levels and could benefit from supplementation. These include those with limited sun exposure (such as people who work indoors or live in northern climates), individuals with darker skin (which produces less vitamin D from sunlight), older adults (whose skin synthesises vitamin D less efficiently), and those following a vegan diet (if they choose a plant-based D3 from lichen, whilst this product’s source is not specified). If you suspect you may be deficient, a simple blood test can help determine your vitamin D status and guide appropriate supplementation.

How to Use Source Naturals Vitamin D3 Drops

Take 9 drops once daily, either directly or mixed into a beverage. Each drop provides approximately 222 IU of vitamin D3, so 9 drops deliver 2000 IU. Because vitamin D is fat-soluble, taking it with a meal that contains healthy fats can enhance absorption. The liquid form offers flexibility—you can adjust the number of drops based on your GP’s recommendations. Store in a cool, dry place away from direct sunlight.
