A Plant-Based Vitamin D3 at 1000 IU

Vitamin D3 — Cholecalciferol — is the form of vitamin D your body produces when skin is exposed to UVB sunlight. Almost all commercial D3 supplements are derived from lanolin, a wax from sheep's wool. This formulation uses a different source: cholecalciferol derived from algae, providing a genuinely plant-based D3 at 25µg (1000 IU) per tablet, suitable for vegans and vegetarians.

More Than a Standard D3 Supplement

Most D3 supplements use lanolin — a wax extracted from sheep's fleece during wool processing. For vegans and vegetarians, this makes D3 supplementation a concession on dietary values. This formula uses cholecalciferol derived from algae — the same molecular form as sunlight-produced D3, from a plant-based origin. At 1000 IU (25µg) per tablet and 180 tablets per bottle, it provides six months of daily coverage in a single purchase.

A Simple Daily Habit

One tablet per day, taken with food and water. Vitamin D is fat-soluble, meaning it is stored in the body and absorbed more effectively when taken alongside food containing some fat. At 180 tablets per bottle, a single bottle covers six months at the one-tablet daily dose — fewer reorder cycles and uninterrupted coverage through seasons when UK sunlight does not reliably produce vitamin D in the skin.

About Vitamin D in the UK

The UK's Scientific Advisory Committee on Nutrition (SACN) has recommended that all UK adults consider a daily vitamin D supplement of 10µg (400 IU) through autumn and winter, when sunlight in the UK is insufficient for vitamin D production in the skin. At 25µg (1000 IU), this formula provides 2.5 times the SACN reference dose. Vitamin D is produced in skin by UVB light — a process that is heavily reduced by the UK's latitude between October and April, cloud cover, indoor working patterns and sunscreen use. The vitamin D stored from summer sun is estimated to run out by mid-autumn for most UK adults.

Frequently Asked Questions

Is this suitable for vegans?
Yes. The cholecalciferol in this formula is derived from algae, not lanolin (sheep's wool). No animal-derived ingredients are used.

What is the difference between vitamin D2 and D3?
Vitamin D3 (Cholecalciferol) is the form produced in human skin by UVB sunlight. Vitamin D2 (Ergocalciferol) is derived from plant sources such as yeast and mushrooms. Research generally suggests D3 is more effective at raising and maintaining blood levels of vitamin D than D2. This formula provides the D3 form from an algae-derived plant source.

What is the recommended dose?
Adults take one tablet daily with food and water. Do not exceed the recommended daily dose. If you are pregnant or breastfeeding, or taking medications, consult your healthcare practitioner before use.

How should I store this product?
Store in a cool, dry place out of reach of children. Vitamin D is a fat-soluble vitamin — avoid excessive heat and moisture.
