Your skin makes it itself: under the action of \u003cstrong\u003eUVB rays\u003c\/strong\u003e, a molecule in the skin called \u003cstrong\u003e7-dehydrocholesterol\u003c\/strong\u003e is converted into a precursor of vitamin D3. From there it travels through the liver and kidneys, where it's activated in two stages — and only then does it become biologically active.\u003c\/p\u003e\n\u003cp\u003eThe limitation is geographical, not just a seasonal feeling. UVB rays reach the earth in sufficient quantity only when the sun sits \u003cstrong\u003ehigh above the horizon\u003c\/strong\u003e. At a low angle, the rays pass through a much thicker layer of atmosphere and scatter before reaching the skin. The UK sits between \u003cstrong\u003e50° and 59° north latitude\u003c\/strong\u003e — from roughly October to April, the sun's angle is too low and vitamin D synthesis in the skin essentially stops. A clear sky doesn't help: it's the angle that matters, not the brightness.\u003c\/p\u003e\n\u003cp\u003eThat's why, during the darker half of the year, vitamin D needs to come from food or a supplement. This formula provides \u003cstrong\u003e2000 IU (50 µg) of vitamin D3 — 1000% of the Nutrient Reference Value (NRV)\u003c\/strong\u003e, together with \u003cstrong\u003evitamin K2 (MK-7)\u003c\/strong\u003e and \u003cstrong\u003ecoenzyme Q10\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;font-weight:700;margin:22px 0 6px;line-height:1.35;\"\u003eWhat vitamin D contributes to in the body\u003c\/p\u003e\n\u003cdiv style=\"border:1px solid #d9e8c4;border-radius:10px;padding:16px 18px;background:#f7fbef;\"\u003e\n\u003cp style=\"margin:0;\"\u003e\u003cstrong\u003e1 · Immune system\u003c\/strong\u003e\u003cbr\u003eVitamin D contributes to the normal function of the immune system.

With sufficient levels, absorption is around 30–40%. That's precisely why vitamin D contributes to the normal absorption and utilisation of calcium.\u003c\/p\u003e\n\u003cp\u003e💡 \u003cstrong\u003eFact #3 · It works like a hormone, not a vitamin\u003c\/strong\u003e\u003cbr\u003eAfter being activated in the liver and kidneys, vitamin D acts like a steroid hormone — binding to receptors in the cell nucleus and regulating the activity of hundreds of genes.
