Taking much vitamin D can have a chain reaction effect causing high levels of calcium and phosphorus in the blood because of vitamin D’s role in calcium absorption. Although the current upper limits are set at 4,000 IUs, the evidence suggests that toxicity is rare unless much higher doses of 10,000 IUs or more are taken over a longer duration or while taking high doses of calcium at the same time. Our Experts While our bodies manufacture vitamin D on exposure to sunshine, the levels in many countries is so weak during the winter months that our body makes little or none at all, meaning that dietary supplements are often the best way to safeguard intakes of vitamin D. Many populations, including the majority of those in Europe, require an additional dietary source of vitamin D to achieve and maintain an adequate status of this important vitamin.

It's also popular amongst the five groups identified by the Government at risk of low vitamin D, such as those with specific bone health concerns or the over 65s. We've chosen to suspend our vitamin D3 in a quality sunflower seed oil to support optimal absorption. Capsules are much better suited to oil-based materials, which is why we've decided to use them over tablets.

Vitamin D ima esencijalni značaj za naš organizam. Učestvuje u mnogim biohemijskim procesima, a za osnovnu fiziološku funkciju ovog vitamina, smatra se učešće u metabolizmu kalcijuma i fosfora. Vitamin D je neophodan za resorpciju kalcijuma i fosfora iz digestivnog trakta. Odgovoran je za manje gubitke Ca i P u bubrezima i nužan u procesu njihove ugradnje u koštani materijal. Od suštinske važnosti je za rast i kalcifikaciju kostiju i zuba. Samim tim što učestvuje u metabolizmu kalcijuma, koji je neophodan za normalno funkcionisanje gotovo svih ćelija u našem organizmu, vitamin D je od ključne važnosti za sve vitalne funkcije. Ukoliko organizmu nedostaje vitamin D, resorpcija kalcijuma iz hrane je nemoguća, i organizam za svoje potrebe počinje da koristi kalcijum iz kostiju. Za posledicu se javlja rahitis kod dece, a kod odraslih osteomalacija (omekšavanje kostiju) i osteoporoza (gubitak koštane mase). Nedostatak vitamina D odraziće se na slabljenje imunološke funkcije, zdravlje i kvalitet kostiju, zuba i mišića, ali i na stanje organizma u celini.

Ayla Barmmer, MS, RD, LDN, founder and CEO of FullWell, notes that most people could benefit from vitamin D supplementation. “We are no longer living primarily outside in nomadic tribes. We wear sunscreen and spend a lot more time indoors than our ancestors, which is in part why supplementation fills a gap that modern living creates.”This can cause low blood vitamin D levels, especially during winter months when there is even less sunlight. Ultra Vitamin D provides extra strength vitamin D, a nutrient that plays a truly remarkable role in the body and is important for many areas of health. It not only contributes to the maintenance of normal bones and teeth but is also known for its role in supporting normal function of the immune system, normal cell division and normal muscle function. Vitamin D is a fat soluble vitamin found in foods such as mushrooms, oily fish, butter and egg yolk. Vitamin D has functions and benefits that are probably more wide ranging than any other vitamin. Vitamin D is synthesized by the body on exposure to sunlight. However, many areas of the world receive insufficient sunlight and even in sunny areas, many choose to limit their exposure due to the negative health effects of excessive exposure to the sun's UV rays. These factors have led to widespread low vitamin D levels in many parts of the world.
