Why choose vitamin D3 over D2?

Vitamin D3 (cholecalciferol) is the form your skin makes from contact with sunlight. It’s the preferred ingredient for use in food supplements due to it being more effective at maintaining healthy levels than D2 (ergocalciferol).

Product Details

4HIM&HER Vitamin D3 provides a full 365-day supply of cholecalciferol (from lanolin) in once-daily 100 μg tablets – daily maintenance for those who want a maximum dosage option.

Vitamin D (cholecalciferol/D3):

  • contributes to the normal function of the immune system¹
  • contributes to maintenance of normal bones, muscles and teeth¹
  • contributes to normal absorption and utilisation of calcium and phosphorus, and to normal blood calcium levels¹
  • has a role in the process of cell division¹

Other ingredients: bulking agents (dicalcium phosphate, microcrystalline cellulose); anti-caking agents (magnesium stearate, silicon dioxide).

¹ EU-authorised health claims (see references below).

  • Adults who get little sun exposure or cover their skin.
  • People who want convenient, once-daily support for bones, muscles, teeth and immunity (EU-approved claims).
  • Those who seek or have been advised a higher-dose option for maintaining healthy vitamin D levels.

Not suitable for vegans (vitamin D3 is derived from lanolin/sheep’s wool). Vegetarians: typically suitable.

  • Take one tablet daily with water, preferably with a meal.
  • Do not exceed the recommended intake.
  • Food supplements should not replace a varied diet.

Vitamin D status builds gradually with consistent daily use; timing depends on sun exposure, diet and baseline levels. The key is regular daily intake alongside a balanced diet.
