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

What Is Vitamin D3?

Vitamin D3, also called cholecalciferol, is the very same form your skin makes when sunlight hits it. Unlike vitamin D2, D3 is far more effective at raising and keeping your blood levels of this essential nutrient. As a fat-soluble vitamin, it helps your body absorb calcium, which in turn maintains strong bones and teeth. It also supports a healthy immune system and normal muscle function.* Member Mark Vitamin D3 is sourced for quality and purity, delivering a reliable 50 mcg (2000 IU) dose in an easy to swallow softgel.

Key Benefits of Vitamin D3

• Immune Health: Vitamin D helps modulate the immune system, promoting a healthy defence against seasonal challenges.*
• Bone Strength: By aiding calcium absorption, vitamin D helps maintain bone density and may reduce 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?

Vitamin D is crucial for overall health, yet many Australians don't get enough from sunshine alone—especially in winter. Member Mark Vitamin D3 provides 2000 IU (50 mcg) of cholecalciferol per softgel, the preferred form for immune function, bone density, and muscle strength.* Each bottle contains 400 soft-gels, giving you a convenient three-month supply for daily wellbeing.

Recommended Dosage of Vitamin D

The National Health and Medical Research Council 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.

Who Should Take Vitamin D3?

Vitamin D deficiency is common, especially in people with limited sun exposure, those with darker skin, older adults, or those living in southern parts of Australia. If you spend most of your time indoors, wear sunscreen regularly, or follow a vegan diet (note: this D3 is typically sourced 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.

Choosing a Quality Vitamin D Supplement

Look for vitamin D3 (cholecalciferol) rather than D2, as D3 is more bioavailable. 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 labelled 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 hypercalcaemia or kidney disease, consult your doctor before use. Store in a cool, dry place and keep out of reach of children. Always read the labelled and follow directions for use.
