BulkSupplements.com Vitamin D3 Powder - Cholecalciferol, 5000 IU per Serving - Gluten-free, 100g (3.5 oz)

Understanding Vitamin D3 and D2

Vitamin D is an essential fat-soluble nutrient that occurs in two main forms: D2 (ergocalciferol) from plant sources and D3 (cholecalciferol), the kind naturally produced by your skin when exposed to sunlight. D3 is considered more bio-available, meaning your body may uses it more effectively to maintain optimal vitamin D levels. This product supplies pure vitamin D3 in a convenient powder form.

Key Benefits of Vitamin D Supplementation

• Contributes to normal bone health by aiding the absorption and utilisation of calcium and phosphorus.
• Supports the normal function of the immune system through its role in immune cell activity.
• Contributes to normal muscle function and helps maintain daily physical performance.
• Has a role in the process of cell division and overall cellular health.

Who Needs Vitamin D Supplementation?

Many people have low vitamin D levels due to limited sun exposure, darker skin, older age, or living in northern latitudes. Those following strict vegan diets should note that this D3 is derived from lanolin (sheep wool). A blood test can help determine your specific needs; always consult a health care professional before starting any new supplement.

Recommended Dosage of Vitamin D

One level scoop (50 mg) provides 125 mcg (5000 IU) of vitamin D3. For maintenance, many experts suggest 600–2000 IU daily, while higher doses may be used under medical supervision to correct deficiency. Since vitamin D is fat-soluble, taking it with a meal containing fat may support absorption.
