Vitamin D3 5000 IU – Immune & Hormonal Support

60 Vegan Capsules · 5000 IU Cholecalciferol · High Absorption · GMP-Certified

AlphaVita Labs Vitamin D3 5000 IU delivers a high-strength therapeutic dose of cholecalciferol (Vitamin D3) — the most bioavailable form of Vitamin D. At 5000 IU per capsule, this is designed for people with confirmed deficiency, limited sun exposure, or those wanting optimal rather than baseline D3 levels.

Why Vitamin D3?

Vitamin D deficiency affects an estimated 1 in 5 adults in the UK. Unlike Vitamin D2, cholecalciferol (D3) is the form produced by your skin in sunlight and is significantly more effective at raising and maintaining serum 25(OH)D levels. Vitamin D3 functions as a steroid hormone, regulating over 200 genes involved in immune function, bone mineralisation, muscle strength, and hormonal balance.

Key Benefits

• Immune system support — regulates innate and adaptive immune responses
• Bone health — essential for calcium absorption and bone mineralisation
• Hormonal balance — supports testosterone production and thyroid function
• Mood and mental health — low D3 is strongly linked to seasonal depression and low mood
• Muscle strength — supports neuromuscular function and reduces fall risk
• Cardiovascular health — associated with healthy blood pressure regulation

How to Take

Take 1 capsule daily with a meal containing fat — Vitamin D3 is fat-soluble. Morning or lunchtime recommended. If in doubt about appropriate dosing, consult your GP and request a serum 25(OH)D blood test.
