Zahler Vitamin D3 5000 IU is a high-strength daily vitamin D supplement delivering 5000 IU of Vitamin D3 as Cholecalciferol per softgel. Vitamin D3 is one of the most important nutrients for overall health, supporting bones, muscles, teeth and immune function, yet deficiency remains common, particularly in the UK where sunlight is limited for much of the year. This high-potency formula provides a meaningful daily dose in a small, easy-to-swallow softgel that fits seamlessly into any daily routine.

What makes it work:

  • Vitamin D3 as Cholecalciferol 5000 IU (125 mcg, 625% daily value), the most bioavailable and body-ready form of vitamin D, supporting a wide range of essential functions including calcium absorption, bone density, muscle health and immune system regulation
  • At 5000 IU per softgel, this high-strength vitamin D supplement is suited for adults who want to actively maintain or restore healthy vitamin D levels, particularly during autumn and winter when sun exposure is minimal
  • Supports healthy bone density and teeth by promoting calcium absorption and utilisation
  • Plays an important role in supporting a healthy immune system, helping the body maintain its natural defences year round
  • Supports healthy muscle function, making it a well-rounded daily supplement for active adults and those looking to support their overall physical wellbeing
  • The small, easy-to-swallow mini softgel format makes daily compliance straightforward and comfortable

Why high-strength vitamin D3 matters in the UK:

Vitamin D deficiency is particularly prevalent in the UK due to the limited sun exposure experienced during autumn and winter months. Even during summer, factors such as spending time indoors, cloud cover and using sun cream can all reduce the amount of vitamin D the body produces naturally. A high-strength daily vitamin D supplement helps bridge this gap consistently throughout the year.

What you get in every bottle:

  • 120 softgels per bottle, 120 full servings at the recommended dose
  • Kosher Certified and Halal Approved
  • Vegetarian friendly, non-GMO, gluten free, dairy free, soy free and peanut free
  • GMP certified facility
  • Clean formula with no unnecessary fillers

A complete high-strength vitamin D3 5000 IU supplement for daily bone health, immune support and muscle strength.

How to Use
+ -

Recommended dose:
Take 1 vitamin D3 softgel daily with food.

Tips for best results:

  • Take consistently every day with a meal containing healthy fats as vitamin D3 is fat-soluble and absorbs more effectively with dietary fat
  • Year-round daily use is recommended, not just during winter months
  • Consult your GP for guidance on the right dose for your individual needs, particularly at the 5000 IU strength

Important safety information:

  • Do not exceed the recommended daily intake without guidance from your GP
  • Pregnant or breastfeeding women should consult their GP before use
  • Not recommended for children under 18 without medical advice
  • If you have a known medical condition or take prescribed medication, speak to your GP before starting any new vitamin D supplement
  • Keep out of reach of children
  • Store in a cool, dry place away from direct sunlight
