Vitamin D3 for children is essential for their development and plays a vital role in the normal growth and maintenance of their bones and immune systems.
Children 1 month to 18 years should take 0. Micrograms are used to measure the biological activity of vitamins and are based on the same measure as International Units IU but are not equivalent. So, 1 IU is the biological equivalent of 0.
An RCT evaluated 38 postmenopausal women (median age years) randomized into 3 groups (placebo or daily oral vitamin D2 in either or 10, IU.
By Dr. Kenneth Madden on December 6, Kenneth Madden biography and disclosures. Every year, one-third of older adults age greater than 65 experience one or more falls. Unfortunately, a closer look at the issue revealed the appropriate dose of vitamin D necessary to safely reduce fall and fracture risk remains controversial.

The Public Health Agency PHA is recommending that everyone take vitamin D supplements during the lockdown period to help keep bones, teeth and muscles healthy. Vitamin D is an essential vitamin for everyone and we get it from two main sources, sunlight and food. We are advising that everyone should consider taking a supplement of vitamin D every day to keep their bones, teeth and muscles healthy. Our body also uses the vitamin D from foods like oily fish such as salmon, mackerel, trout, kippers and sardines , eggs and meat, along with foods that have been fortified with vitamin D such as breakfast cereals and most fat spreads.

Winter is upon us and so is the risk of vitamin D deficiency and infections. Vitamin D, which is made in our skin following sunlight exposure and also found in oily fish mackerel, tuna and sardines , mushrooms and fortified dairy and nondairy substitutes , is essential for good health. Humans need vitamin D to keep healthy and to fight infections. The irony is that in winter, when people need vitamin D the most, most of us are not getting enough.
So how much should we take? Should we take supplements? How do we get more? And, who needs it most? I am a medical microbiologist and immunologist who studies the functions of vitamin D in immune cells. My laboratory has been interested in figuring out why the immune system has vitamin D receptors that determine which cells can use vitamin D. In the immune system, vitamin D acts to improve your ability to fight infections and to reduce inflammation.

During the past decade research studies have found that annual doses of vitamin D do not provide much benefit. There are far fewer studies publishing results with annual doses. Mostly the studies being published since are ones which were started many years ago. We are unaware of any new Clinical Trials using annual doses Sometimes annual doses have actually ended up causing problems – such as more falls. Vitamin D is perhaps the only item for which taking the annual amount in a single day will not cause a call to or immediate death.
Quarterly doses of vitamin D results in significant variation in blood levels of vitamin D – which stresses the body. It appears, however, that the benefits of the vitamin D out-weigh the stresses of quarterly dosing. The half-life for vitamin D for most people is approximately 1 month. Evolution has created bodies which typically experience even larger summer-winter changes in vitamin D levels Note: there is some thought that the body needs to have variation in the vitamin D level – so should not keep it at a constant level all year long.

The information included here will help you learn all about calcium and vitamin D — the two most important nutrients for bone health. Calcium is a mineral that is necessary for life.
