The strength appears in the name because strength is the main thing people compare when choosing a vitamin D product.\u003c\/p\u003e\n\u003ch2\u003e4000 IU And 100 Micrograms Are The Same Amount\u003c\/h2\u003e\n\u003cp\u003eThis causes more confusion than anything else on a vitamin D shelf, so it is worth setting out plainly.\u003c\/p\u003e\n\u003cp\u003eVitamin D is written in two units. \u003cstrong\u003eIU\u003c\/strong\u003e means International Units, an older measure still widely used, particularly on the front of packs. \u003cstrong\u003eµg\u003c\/strong\u003e or \u003cstrong\u003emcg\u003c\/strong\u003e means micrograms, the metric measure used in nutrition labelling in the United Kingdom and Europe.\u003c\/p\u003e\n\u003cp\u003eThe relationship between them is fixed: \u003cstrong\u003e1 µg = 40 IU\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e25 µg = 1000 IU\u003c\/li\u003e\n\u003cli\u003e50 µg = 2000 IU\u003c\/li\u003e\n\u003cli\u003e75 µg = 3000 IU\u003c\/li\u003e\n\u003cli\u003e100 µg = 4000 IU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSo a pack advertising \"4000 IU\" and a pack advertising \"100 mcg\" are advertising the same amount. If you are comparing products, convert them both to one unit first — otherwise the larger-looking number wins for no reason.\u003c\/p\u003e\n\u003ch2\u003eChoosing Between The Strengths In This Range\u003c\/h2\u003e\n\u003cp\u003eThere are two strengths of vitamin D3 in the range, plus a vegan option at the lower strength. The difference between them is quantity. All are vitamin D3, which is cholecalciferol.\u003c\/p\u003e\n\u003cp\u003eHigher is not automatically better, and this is the one place on this page where we would rather you stopped and thought than simply added to basket. If you already take a multivitamin, a combined D and K product, or anything else containing vitamin D, the amounts add together — and that is the most common way people end up taking more than they meant to.\u003c\/p\u003e\n\u003cp\u003eWhich strength suits you is a question for your doctor or pharmacist. They can look at everything you take, which a product page cannot.\u003c\/p\u003e\n\u003ch2\u003eD2, D3, Lanolin And Lichen\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eD2\u003c\/strong\u003e is ergocalciferol, typically derived from yeast or fungi. \u003cstrong\u003eD3\u003c\/strong\u003e is cholecalciferol, the form used in most supplements.\u003c\/p\u003e\n\u003cp\u003eMost D3 on the market is derived from \u003cstrong\u003elanolin\u003c\/strong\u003e, the oil from sheep's wool, which means it is not suitable for vegans. D3 can also be made from \u003cstrong\u003elichen\u003c\/strong\u003e, which is plant-based. This is a raw-material difference, not a labelling one, and it is why our range carries a separate vegan D3 rather than describing this one as suitable for everyone.\u003c\/p\u003e\n\u003ch2\u003eWhy Vitamin D Comes Up So Much In The United Kingdom\u003c\/h2\u003e\n\u003cp\u003eVitamin D can be obtained from food and also produced by the body through skin exposure to sunlight. Dietary sources are relatively few — oily fish, egg yolk, liver, and fortified foods such as some spreads and cereals.\u003c\/p\u003e\n\u003cp\u003eAt the latitude of the United Kingdom, usable sunlight varies considerably between summer and winter. That seasonality is why vitamin D is discussed here more than in sunnier countries, and why many people take it specifically in the darker months.\u003c\/p\u003e\n\u003ch2\u003eHow It Fits Into Your Routine\u003c\/h2\u003e\n\u003cp\u003eVitamin D is fat-soluble, so it is generally suggested to be taken with a meal containing some fat. It attaches to a mealtime rather than needing a slot of its own.\u003c\/p\u003e\n\u003ch2\u003eWhat You Get In Each Pack\u003c\/h2\u003e\n\u003cp\u003eA single pack, a 2 pack and a 4 pack. Identical product in each; only the quantity changes. Prices are shown on this page before you add anything to your basket.\u003c\/p\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eAdults who want the higher-strength vitamin D3 in the range, and who have checked what else in their routine already contains vitamin D.\u003c\/p\u003e\n\u003cp\u003eIf you follow a vegan diet, choose the vegan D3 instead — standard D3 is usually derived from lanolin. Do not exceed the recommended daily dose, and speak to your doctor before taking it if you are pregnant, breastfeeding, taking medication or under medical supervision.\u003c\/p\u003e\n\u003ch2\u003eQuestions, Answered\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eIs 4000 IU the same as 100 micrograms?\u003c\/strong\u003e\u003cbr\u003eYes. 1 µg equals 40 IU, so 100 µg is 4000 IU.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I convert between IU and micrograms?\u003c\/strong\u003e\u003cbr\u003eDivide IU by 40 to get micrograms, or multiply micrograms by 40 to get IU.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between 1000 IU and 4000 IU?\u003c\/strong\u003e\u003cbr\u003eQuantity. Both are vitamin D3. Which suits you is a question for your doctor or pharmacist, particularly if you take other products containing vitamin D.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan vitamin D add up across different supplements?\u003c\/strong\u003e\u003cbr\u003eYes. Multivitamins and combined products often contain vitamin D, and the amounts add together. Check the labels of everything you take.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between vitamin D2 and D3?\u003c\/strong\u003e\u003cbr\u003eD2 is ergocalciferol, usually from yeast or fungi. D3 is cholecalciferol, the form used in most supplements.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs vitamin D3 vegan?\u003c\/strong\u003e\u003cbr\u003eNot usually. Most D3 is derived from lanolin, from sheep's wool. D3 from lichen is plant-based, which is why a separate vegan product exists in our range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich foods contain vitamin D?\u003c\/strong\u003e\u003cbr\u003eOily fish, egg yolk and liver, plus fortified foods such as some spreads and cereals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I take it with food?\u003c\/strong\u003e\u003cbr\u003eVitamin D is fat-soluble and is generally suggested to be taken with a meal containing some fat.
