Klaire Labs SFI Health Vitamin D3 5000 IU – 100 Capsules

Understanding Vitamin D3

Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that your body naturally produces when skin is exposed to sunlight. Many people in the UK, particularly during autumn and winter, do not get enough sun exposure to maintain adequate levels. Klaire Labs Vitamin D3 5000 IU provides 125 mcg of bio-available vitamin D3 per capsule, making it a convenient high-potency option to help top up your levels.

Key Benefits of Vitamin D3

• Immune Function: Vitamin D contributes to the normal function of the immune system.*
• Bone Health: It contributes to the maintenance of normal bones by aiding calcium and phosphorus absorption.*
• Muscle Function: Adequate vitamin D levels help maintain normal muscle function.*
• Cell Division: Vitamin D has a role in the process of cell division.*

Who May Need Extra Vitamin D3?

Individuals with limited sun exposure, older adults, people with darker skin, and those following restrictive diets may have increased requirements. Athletes and active individuals also often benefit from vitamin D3 to support muscle recovery and bone density. Since vitamin D is fat-soluble, taking this supplement with a meal containing healthy fats optimises absorption.
