Member Mark Vitamin D3, 50 mcg (2000 IU), 400 Soft gels

What Is Vitamin D3?

Vitamin D3, or cholecalciferol, is the same form your body produces when your skin is exposed to sunlight. Unlike vitamin D2, D3 is more efficient at raising and maintaining your blood levels of this essential nutrient. As a fat-soluble vitamin, it plays a key role in calcium absorption, which helps keep your bones and teeth strong. It also supports a healthy immune system and normal muscle function.* Member Mark Vitamin D3 is sourced for quality and purity, delivering a reliable dose in an easy-to-swallow softgel.

Key Benefits of Vitamin D3

• Immune Health: Vitamin D helps regulate the immune system, promoting a healthy defence against seasonal challenges.*
• Bone Strength: By aiding calcium absorption, Vitamin D contributes to maintaining bone density and lowering the risk of fractures as you age.*
• Muscle Function: Adequate Vitamin D levels support normal muscle contraction and may help preserve muscle mass.*
• Mood and Wellbeing: Some research suggests Vitamin D plays a role in mood regulation, though individual results vary.

Why Choose Vitamin D3 for Immune support?

Many people don't get enough Vitamin D from sun exposure alone, especially in Canada where sunlight is limited during winter. Member Mark Vitamin D3 provides 50 mcg (2000 IU) of cholecalciferol per softgel—the preferred form for supporting immune function, bone density, and muscle strength.* With 400 soft gels per bottle, this supplement offers a convenient three-month supply for daily wellness.

Who Should Take Vitamin D3?

Vitamin D deficiency is common, particularly in individuals with limited sun exposure, darker skin, older adults, or those living in northern latitudes. If you spend most of your time indoors, wear sunscreen regularly, or follow a vegan diet (note: this D3 is typically derived from lanolin), supplementation can help maintain optimal levels. Always consult your health care provider before starting any new supplement, especially if you have a known deficiency or are taking medications.

Recommended Dosage of Vitamin D

Health Canada recommends a daily intake of 600-800 IU for most adults, but many experts suggest higher doses for those at risk of deficiency. Each Member Mark softgel provides 2000 IU (50 mcg), a level commonly used for maintenance and correction of low levels. Because Vitamin D is fat-soluble, take it with a meal containing fat for best absorption. Do not exceed the recommended dose without medical supervision.

Choosing a Quality Vitamin D Supplement

Look for vitamin D3 (cholecalciferol) rather than D2, as D3 is more bio-available. Soft gels are an effective delivery form because the oil base aids absorption. Member Mark Vitamin D3 is manufactured in facilities that follow stringent quality control procedures. For those with dietary restrictions, check the label for allergens—this product is formulated without common allergens, but always verify.

Safety and Side Effects

Vitamin D is generally safe at recommended doses, but extremely high intake (over 10,000 IU daily for extended periods) can lead to toxicity. Symptoms may include nausea, weakness, and kidney issues. If you are pregnant, nursing, or have a medical condition such as hypercalcemia or kidney disease, consult your doctor before use. Store in a cool, dry place and keep out of reach of children.
