What Makes This Vitamin D3 Special?

You might think you're getting enough vitamin D from the sun, but for many Aussies, that's simply not the case. Members Mark Vitamin D3 provides a convenient 2000 IU (50 mcg) dose per softgel to help support your immune system, bone strength, and muscle function. This non-GM, Gluten Free formula comes in a 400-count bottle that'll last you over a year. Vitamin D3 (cholecalciferol) is the form naturally produced by your skin when exposed to sunlight, and it's recognised as more effective at raising and maintaining blood levels than vitamin D2. Each softgel is easy to swallow and designed for maximum bioavailability when taken with a meal containing fat.

Key Benefits of Vitamin D3

  • Immune Support: Vitamin D3 helps maintain a healthy immune system by supporting the function of immune cells.*
  • Bone Health: Vitamin D3 assists in calcium absorption, which is crucial for maintaining strong bones and teeth.*
  • Muscle Function: Adequate vitamin D levels contribute to normal muscle function and may help reduce the risk of falls in older adults.*
  • Calcium Balance: By promoting calcium absorption, vitamin D3 helps maintain proper calcium levels in the blood.*

Who Needs Vitamin D3 Supplementation?

Many individuals may benefit from vitamin D3 supplementation, including those with limited sun exposure (living in southern Australia or spending most time indoors), people with darker skin (which produces less vitamin D from sunlight), older adults (whose skin synthesises vitamin D less efficiently), and individuals following a vegan or vegetarian diet (since natural food sources are limited). Members Mark Vitamin D3 is a simple way to fill the gap for anyone aiming to maintain healthy vitamin D levels.*

Recommended Dosage of Vitamin D

Health experts often recommend a daily intake of 600–800 IU (15–20 mcg) for most adults, but many choose higher amounts like 2000 IU (50 mcg) per day for additional support. This product provides 2000 IU per softgel, making it suitable for those seeking a moderate daily dose. Always consult your health care provider to determine the right dosage for your individual needs, especially if you have a known deficiency or are taking other medicines.*

Why Choose Members Mark Vitamin D3?

Vitamin D is essential for overall wellbeing, yet many people don't get enough from sun exposure or diet alone. Members Mark Vitamin D3 delivers high-potency vitamin D3 with a pure, non-GM formula free from artificial additives. This 400-count bottle provides a convenient 13-month supply to help you maintain healthy vitamin D levels year-round.

Choosing a Quality Vitamin D Supplement

When selecting a vitamin D supplement, look for a pure formula free from unnecessary additives. Members Mark Vitamin D3 is non-GM, Gluten Free, and contains no artificial flavours, synthetic dyes, sugar, soy, or dairy. The soft-gels are bottled in the USA, ensuring quality and consistency. With 400 soft-gels per bottle, you get an extended supply that simplifies your daily routine.

Safety and Side Effects

Vitamin D3 is generally safe when taken as directed. However, excessive intake (typically above 10,000 IU per day) can lead to toxicity over time. Stick to the recommended serving of one softgel daily. If you are pregnant, nursing, or have a medical condition, consult your health professional before starting any supplement.*
