Source Naturals Vitamin D-3 Bioactive Form for Bone & Immune Health* 5000 IU (125 mcg) - 60 Capsules

Who Should Consider a Vitamin D3 Supplement?

Many Canadians are at risk of vitamin D deficiency due to limited sun exposure, especially during fall and winter. Those with darker skin, older adults, and individuals following a vegan diet may also have lower levels. Supplementing with vitamin D3 can help maintain optimal blood levels. Source Naturals Vitamin D-3 provides a potent 5000 IU (125 mcg) dose to support bone and immune health, making it a convenient choice for those with increased needs.

Key Benefits of Vitamin D3

Vitamin D plays several vital roles in the body. It helps the body absorb calcium and phosphorus, which are essential for maintaining strong bones and teeth. Adequate levels also support normal muscle function and contribute to a healthy immune system. Here are the primary benefits:

• Bone Health: Promotes calcium absorption and bone mineralization, helping maintain bone density.
• Immune Function: Regulates the immune response, supporting the body's natural defences.
• Muscle Strength: Contributes to normal muscle function, important for mobility and fall prevention in seniors.
• Calcium Balance: Works with parathyroid hormone to regulate blood calcium levels.

These benefits make vitamin D3 a foundational supplement for overall wellness.

How Much Vitamin D3 Should You Take?

Health Canada recommends a daily intake of 600 IU for adults up to age 70 and 800 IU for those over 70. However, many individuals may require higher doses to achieve optimal blood levels. Each capsule of Source Naturals Vitamin D-3 delivers 5000 IU (125 mcg), a widely used dose for maintenance and correction of deficiency. It's important to have your vitamin D levels tested and consult a healthcare practitioner to determine the right dose for you. As a fat-soluble vitamin, take it with a meal containing fat for best absorption.

Understanding Vitamin D3 and D2

There are two main forms of vitamin D: ergocalciferol (D2) from plants and fortified foods, and cholecalciferol (D3) produced in human skin upon sun exposure and found in animal sources. Research shows D3 is more effective at raising and maintaining blood levels. Source Naturals Vitamin D-3 uses cholecalciferol, the same form your body naturally synthesises.

What to Look for in a Vitamin D3 Supplement

Quality is key. Source Naturals Vitamin D-3 is manufactured in the USA in a GMP-compliant facility. The formula is free from yeast, dairy, egg, gluten, soy, wheat, preservatives, and artificial colours, flavors, or fragrances. This makes it suitable for individuals with food sensitivities. The brand has been trusted for over 35 years, ensuring you receive a reliable product.

Safety and Side Effects

Vitamin D3 is generally well-tolerated at recommended doses. However, excessive intake can lead to toxicity because it is fat-soluble. Health Canada's tolerable upper intake level for adults is 4000 IU per day. Symptoms of excessive intake include nausea, vomiting, weakness, and kidney issues. Always consult your healthcare practitioner before use, especially if you are pregnant, nursing, or taking medications. Keep out of reach of children.

Always read the label and follow directions for use. Consult a healthcare practitioner before use if you are taking medications or have a medical condition.
