Understanding Vitamin D3 and D2
Vitamin D exists in two primary forms: D2 (ergocalciferol) and D3 (cholecalciferol). While both can increase blood levels, research indicates that D3 is more effective at sustaining adequate levels over time. D3 is the form naturally synthesised in human skin upon sun exposure and is also found in animal-based foods. NaturesPlus uses vitamin D3 derived from lanolin, providing a source closely resembling what your body produces. The body's absorption and utilisation of vitamin D depend on its form; D3 has a higher affinity for vitamin D-binding proteins, potentially offering better bioavailability and longer-lasting benefits. For most individuals, D3 is the recommended choice for supplementation.

Key Benefits of Vitamin D3
Vitamin D3 plays several crucial roles in the body. Here are some well-recognized benefits supported by nutritional science:
-
Supports bone health: Vitamin D helps regulate calcium and phosphorus absorption, essential for maintaining strong, healthy bones.
-
Promotes immune function: Adequate vitamin D levels are associated with a balanced immune response, helping your body defend against everyday challenges.
-
Assists muscle function: Vitamin D contributes to normal muscle contraction and may support physical performance.
-
Supports calcium absorption: Without sufficient vitamin D, the body cannot absorb calcium efficiently, even if consumed in the diet.
Remember, vitamin D is a fat-soluble vitamin, so taking it with a meal containing fat can enhance absorption.
Who May Benefit from Vitamin D3 Supplementation?
Certain individuals are more prone to low vitamin D levels. You might consider supplementation if you:
- Spend most of your time indoors or live in northern latitudes with limited sun exposure, common in many parts of Canada.
- Have darker skin, which reduces natural vitamin D production from sunlight.
- Are over the age of 60, as skin synthesis declines with age.
- Follow a vegan diet, though note that this D3 is from lanolin (sheep's wool) and is not vegan.
- Have conditions that affect fat absorption, such as Crohn's or coeliac disease.
Many adults find that 5000 IU per day helps maintain healthy levels, but individual needs vary. A simple blood test from your healthcare provider can determine if you are deficient.
Recommended Dosage and Usage
NaturesPlus suggests taking one softgel daily, preferably with a meal. Each bottle contains 60 softgels, providing a two-month supply at the recommended serving. At 5000 IU per softgel, this supplement falls within the range commonly used for maintenance and correcting deficiencies. However, it is always wise to consult a healthcare professional before starting any new supplement, especially if you take other medications or have underlying health conditions. Because vitamin D is fat-soluble, it can accumulate in the body. While toxicity is rare at typical doses, it is important not to exceed recommended intakes without medical supervision.
Safety Considerations
Vitamin D3 is generally well-tolerated, but extremely high doses over long periods can lead to toxicity. Signs of excessive vitamin D include nausea, weakness, and kidney issues. If you are pregnant, nursing, or have a condition like hypercalcemia, speak with your doctor before use. Keep out of reach of children. Always read the label and follow directions for use. Store in a cool, dry place and use before the expiration date printed on the bottle.
