Member Mark Vitamin D3, 50 µg (2000 IU), 400 Soft gel capsules

What Is Vitamin D3?

Vitamin D3, also known as cholecalciferol, is the same form your skin produces when exposed to sunlight. It is more effective than vitamin D2 at raising and maintaining blood levels of vitamin D. This fat-soluble vitamin plays a vital role in calcium absorption, which helps maintain strong bones and teeth. It also contributes to the normal function of the immune system and normal muscle function.* Member Mark Vitamin D3 is sourced for quality and purity, delivering a reliable dosage in an easy-to-swallow soft gel capsule.

Why Choose Vitamin D3 for Immune Support?

Vitamin D is vital for maintaining good health, yet many of us don't get enough from sunlight alone. Member Mark Vitamin D3 provides 50 µg (2000 IU) of cholecalciferol per soft gel capsule—the preferred form of vitamin D for supporting immune function, bone density, and muscle strength.* With 400 soft gel capsules per bottle, this supplement offers a convenient three-month supply for daily wellness.

Key Benefits of Vitamin D3

• Immune Health: Vitamin D contributes to the normal function of the immune system, helping your body defend against seasonal challenges.*
• Bone Strength: By aiding calcium absorption, vitamin D contributes to the maintenance of normal bones and may help reduce the risk of fractures as you age.*
• Muscle Function: Adequate vitamin D levels support normal muscle contraction and help maintain muscle mass.*

Who Should Take Vitamin D3?

Vitamin D deficiency is common, especially in people 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 sourced from lanolin), supplementation can help maintain optimum levels. Always consult your health care practitioner before starting any new supplement, especially if you have a known deficiency or are taking medications.

Recommended Dosage of Vitamin D

The National Health Service (NHS) recommends a daily intake of 10 µg (400 IU) for most adults, but many experts suggest higher doses for those at risk of deficiency. Each Member Mark soft gel capsule provides 2000 IU (50 µg), 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 bioavailable. Soft gel capsules 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, cheque 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 undertake.
