Natural Factors Whole Earth & Sea Vitamin D3 – Vegan & Non-GM – 90 Vegetarian Capsules

Understanding Vitamin D3 and D2

Vitamin D exists in two primary forms: D2 (ergocalciferol) from plant sources and D3 (cholecalciferol), which is typically derived from animal sources but can also be obtained from lichen, making it suitable for vegans. Research indicates that D3 may be more effective at raising and maintaining blood levels of vitamin D compared to D2. Natural Factors uses vegan D3 from lichen, offering the preferred form without compromising dietary principles.

Who Needs Vitamin D Supplementation?

While the body can produce vitamin D through sunlight exposure, many people cannot rely on this alone. Supplementation may be beneficial for those living in northern latitudes with limited winter sun, individuals with darker skin (as melanin reduces synthesis), older adults, vegans and vegetarians, and anyone avoiding excessive sun exposure.

Why Vitamin D Matters for Your Health

Vitamin D is essential for numerous bodily functions. It aids calcium absorption, supports bone and dental health, contributes to normal immune function, and plays a role in muscle function. In the UK, many people have insufficient levels, particularly during autumn and winter. Natural Factors Whole Earth & Sea Vitamin D3 provides a reliable plant-based source to help maintain optimal levels.

Key Benefits of Vitamin D

Vitamin D has several scientifically recognized roles in the body:

• Bone health: Vitamin D contributes to the maintenance of normal bones.
• Immune support: Vitamin D contributes to the normal function of the immune system.
• Muscle function: Vitamin D contributes to the maintenance of normal muscle function.
• Calcium absorption: Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus.

These benefits are supported by the European Food Safety Authority (EFSA).

Recommended Dosage of Vitamin D

The UK government recommends a daily intake of 10 mcg (400 IU) for the general population, but many health professionals advise higher levels for optimal health. Natural Factors Whole Earth & Sea Vitamin D3 provides 125 mcg (5000 IU) per capsule. As with any supplement, consult a health care professional to determine your individual needs.
