Our Maximum Strength Vitamin D3 2000iu capsules are engineered to deliver highly bioavailable cholecalciferol to optimise bone health, particularly for those with specific bone health concerns. Designed for maximum absorption, our 2000iu D3 formulation is also a good choice for those with low vitamin D status.

Product Overview & Key Benefits

  • Maximum Strength: Delivers 2000iu (50µg) of pure-grade vitamin D3 per single, easy-to-swallow capsule.


  • Enhanced Bioavailability: Formulated with cholecalciferol (D3), the body’s naturally synthesised form of Vitamin D, which is proven to be more readily absorbed than plant-derived D2 (ergocalciferol).

  • Superior Absorption Base: Suspended in premium sunflower seed oil. Oil-based capsules significantly improve the absorption of fat-soluble vitamin D compared to standard tablets.

  • Premium Quality Standards: Manufactured in the UK under strict Good Manufacturing Practice (GMP) certification to guarantee purity and safety.

  • Vegetarian Friendly: Sourced from high-quality ingredients suitable for vegetarians. (Note: Contains lanolin-derived D3; not suitable for vegans).

Who Needs Vitamin D3?

UK Government advice is that everyone should consider taking 10mcg (400iu) of vitamin D daily for healthy bones and muscles. This is particularly important during the winter months.

NHS Inform states that certain groups are at increased risk of vitamin D deficiency and should take a daily 10mcg (400iu) vitamin D supplement all year. These groups include:

•    All pregnant and breastfeeding women.
•    Infants and children under 5 years old (unless consuming over 500ml of infant formula daily).
•    Individuals with low or no sun exposure, such as:

o    Those who cover their skin for cultural reasons.
o    People who are housebound or stay indoors for long periods.
o    Residents of care homes.

•    People from minority ethnic groups with dark skin (e.g., African, African-Caribbean, South Asian origin), as they require more sun exposure to produce the same amount of vitamin D.

James U. ★★★★☆

Sized right for daily bone support, these capsules are easy to swallow and don’t leave any aftertaste. I’ve been taking them for three weeks and my levels feel steadier, just wish the bottle came with a few more for the price.

Ryan ★★★★☆

The 2000iu dose is exactly what I needed for my daily bone health support—no aftertaste or weird burps with these capsules. Only giving four stars because the bottle's seal was a bit tricky to open at first.
