Some supplements contain both vitamins D and K together. This is because both are needed for calcium metabolism: vitamin D promotes calcium absorption and vitamin K promotes the calcification of bones and reduces the calcification of soft tissues such as blood vessels (which is a risk with very high vitamin D and calcium intake). From about late March/early April to the end of September, most people should be able to make all the vitamin D they need from sunlight. Some people are at higher risk of vitamin D deficiency. If you are in one of these groups the NHS recommends you take a vitamin D supplement all year around.Usually, most of your body’s vitamin D is in storage, bound to either vitamin D receptors or carrier proteins. Very little “free” vitamin D is available ( 1, 2).

Vitamin D is a fat-soluble vitamin, so it's best to have your supplement with food for optimum absorption.

Summary Read on for advice on how much to take and when, who's more at risk of deficiency and the cheapest places to buy vitamin D tablets, sprays and gummies. Vitamin D3 is considered essential for our bodies as it contributes to the maintenance of normal bones, teeth, muscle function and also supports the normal absorption of calcium and phosphorus. However, it is naturally found in relatively few foods like oily fish, meat and eggs and most of it comes from exposure to sunlight. To maintain your vitamin D levels or prevent deficiency you'll usually take colecalciferol long term.

However, experts have cautioned that much smaller amounts could be associated with health risks. The Food and Nutrition Board indicates that even amounts less than the Tolerable Upper Intake Level (UL) of 4,000 IU (100 mcg) could have negative health effects over time ( 7). Children aged 1 to 4 years old should be given a daily supplement containing 10 micrograms of vitamin D throughout the year. VEGAN WITH NO FILLERS, BINDERS OR ADDITIVES.
