What is the Sunshine Vitamin?
Vitamin D3 is fondly referred to as the 'sunshine vitamin' because it is commonly sourced from the sun's rays. Although this essential nutrient is vital for many different functions in the body, it is most popularly taken to maintain strong bones and teeth. Vitamin D also helps to promote a healthy immune system and normal muscle function.
Why Choose Vitamin D3 Tablets 4,000iu?
The resident team of expert nutritionists at Simply Supplements have exclusively formulated this Vitamin D3 4,000iu supplement to help boost vitamin D levels in those with an insufficiency or clinical deficiency.
✓ Maximum strength - our tablets provide 4,000iu of Vitamin D3.
✓ Supports normal immune function – helps your body's natural defences work at their best
✓ Maintains strong bones and muscles – a key nutrient for active lifestyles and muscle function
✓ Promotes calcium absorption – essential for long-term bone and dental health
✓ One-a-day formula – convenient, effective and expertly formulated for daily use
Higher intakes of vitamin D have been shown to reduce the risk associated with unstable posture and weakened muscles. This is a serious risk factor for bone fractures among men and women of sixty years of age and older. Mature women, in particular, are at increased risk of bone loss due to decreased oestrogen levels after menopause.
