Why we love it
  • Optimal vitamin D3 support.
  • Easily absorbed tablet form.
  • Offers multiple health benefits.
Main Highlights
  • IDEAL EVERYDAY DOSE - 2000 IU vitamin D3 supports optimal levels of vitamin D3 in the body without upsetting the delicate calcium to vitamin D3 ratio
  • OPTIMAL, EASILY ABSORBED, TABLET FORM - cholecalciferol is the superior form produced in the body, which is better absorbed than D2. We also use tablets rather than oil-based capsules to avoid issues with fat malabsorption
  • EASY-TO-SWALLOW - our vitamin D3 tablets are rounded and just 6mm in diameter, suitable for both children and adults
  • IMMUNE SUPPORT & MUSCLE FUNCTION – vitamin D3 contributes to normal functioning of the immune system, and by supporting healthy cell division it also helps to maintain normal muscle function
  • PURE & CLEAN - we only use hypoallergenic ingredients with no unnecessary additives (such as silicon dioxide or magnesium stearate), lab verified, vegetarian (derived from lanolin, not suitable for vegans), GMP manufactured in the UK
