Why Quest Forte D 4000 IU Stands Out: Quality, Science, and Safety You Can Trust
Vitamin D is essential for strong bones, a healthy immune system, and proper muscle function. Quest Forte D 4000 IU is a high-strength vitamin D3 supplement designed to support these vital areas of health—especially for people with low sun exposure or increased needs. At Quest, we understand and respect the concerns raised by consumers regarding the quality and safety of Vitamin D supplements in Malta. We would Like to reassure all our valued customers with the following facts about our commitment to product integrity and pharmaceutical-grade standards:
Unique Formulation and Bioavailability of Quest Forte D 4000 IU
Each tablet of Quest Forte D 4000 IU provides 4000 IU (100 µg) of vitamin D3 (cholecalciferol). This high-strength dose helps raise and maintain vitamin D levels more effectively than lower-dose options—especially in adults who:
- Get little sun exposure due to spending more time indoors, consistent use of sunscreen & Residing in areas with limited sunlight
- Have darker skin pigmentation
- Are over age 60
- Have higher physiological needs
Vitamin D3 is the preferred form of vitamin D, as it is better absorbed and retained in the body than the type commonly used in basic multivitamins (vitamin D2). Quest’s formulation is free from gluten, dairy, and soya, and is suitable for vegetarians.
