Fixed in one softgel daily.\u003c\/p\u003e\u003ch2\u003eThe science\u003c\/h2\u003e\u003cp\u003eVitamin D is technically a hormone precursor — and almost every tissue in the body has vitamin D receptors. Deficiency (serum 25(OH)D below 50 nmol\/L) is estimated to affect over a billion people, with particularly high prevalence at northern latitudes where sunlight is insufficient for synthesis for months at a time. Ireland and the UK are textbook examples.\u003c\/p\u003e\u003cp\u003eRCT evidence supports supplementation for bone density, immune function, mood, and all-cause mortality in deficient populations. D3 (cholecalciferol) raises serum levels significantly more effectively than D2 — the form used in many cheaper supplements. 2,000 IU is a conservative, well-tolerated daily dose appropriate for most adults.\u003c\/p\u003e\u003ch2\u003eHow to take it\u003c\/h2\u003e\u003cp\u003e1 softgel daily with a meal containing fat. D3 is fat-soluble — absorption is meaningfully higher with food. Morning or midday dosing is generally preferred.\u003c\/p\u003e\u003ch2\u003eWhat’s inside\u003c\/h2\u003e\u003cp\u003eEvery batch independently tested.

D2 (ergocalciferol) is plant-derived. Multiple meta-analyses show D3 raises and maintains serum 25(OH)D significantly more effectively than D2 — roughly 87% greater potency in some comparisons. D3 is the clinically preferred form.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if I’m deficient?\u003c\/strong\u003e\u003cbr\u003eA blood test measuring serum 25(OH)D is the only reliable method. Symptoms overlap too broadly with other conditions to be diagnostic. If you live in Ireland, the UK, or a northern latitude and haven’t tested recently, there’s a meaningful probability you’re running low — particularly in winter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShould I pair this with vitamin K2?\u003c\/strong\u003e\u003cbr\u003eThere’s a logical case for it. D3 increases calcium absorption; K2 (MK-7 form) activates the proteins that direct calcium to bone rather than soft tissue. At 2,000 IU the risk is low, but the combination is reasonable for long-term use. Proco’s Bone \u0026amp; Heart Support includes both D3 and K2 in a single formula.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 2,000 IU safe daily?\u003c\/strong\u003e\u003cbr\u003eYes. Toxicity requires prolonged intake at very high doses — typically above 10,000 IU daily for extended periods. 2,000 IU is well within established safe upper limits (the tolerable upper intake level is 4,000 IU for adults). Daily supplementation at this dose is appropriate for most adults without routine monitoring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen’s the best time to take it?\u003c\/strong\u003e\u003cbr\u003eWith your largest meal of the day. Some people report that late-day D3 affects sleep — though the evidence is mixed. Morning or midday dosing is a sensible default if sleep quality matters to you.\u003c\/p\u003e","brand":"Proco","offers":[{"title":"Default Title","offer_id":58008087986440,"sku":"RLC3VTD3","price":20.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1047\/0585\/1656\/files\/1781360568771-generated-label-image-0.jpg?v=1781360605","url":"https:\/\/shop.procohq.com\/products\/vitamin-d3-2-000-iu","provider":"Proco","version":"1.0","type":"link"}
