GNC Vitamin D3 125mcg (5000 IU) Food Supplement, Supports Normal Bones and Teeth, 180 Tablets

Many people in the UK do not get enough vitamin D from sunlight alone, particularly during autumn and winter. That's where GNC Vitamin D3 125mcg (5000 IU) tablets come in, providing a convenient way to support your daily nutrient intake.

Vitamin D3 vs D2: What's the Difference?

There are two main types of vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D3 is the form naturally synthesised by your skin when exposed to sunlight and is found in animal-based foods. Research indicates that D3 may be more effective at raising and maintaining blood levels of vitamin D compared to D2. GNC undertake vitamin D3 to provide a form that closely mimics what your body produces naturally.

Who Might Benefit from Vitamin D Supplementation?

Certain groups may have higher requirements for vitamin D: those with limited sun exposure, people with darker skin (which produces less vitamin D from sunlight), older adults, and individuals following a vegan diet (note that D3 from lanolin is not suitable for vegans). If you are unsure about your vitamin D status, a blood test can help determine whether supplementation is needed. GNC Vitamin D3 is an easy way to ensure a consistent daily dose.

The Role of Vitamin D in Your Body

• Normal bones and teeth: Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, which helps maintain normal bones and teeth.
• Immune function: Vitamin D contributes to the normal function of the immune system.
• Muscle function: Vitamin D contributes to the maintenance of normal muscle function.
• Overall health: Vitamin D is involved in many cellular processes and supports general health and vitality.

Recommended Dosage

The recommended daily allowance (RDA) for vitamin D varies by age and life stage, but many experts suggest 600–2000 IU per day for maintenance. Higher doses, such as the 5000 IU in this supplement, are often used to correct deficiency. The UK government recommends 400 IU (10 mcg) per day for the general population, but higher doses may be appropriate under medical advice.
