The Department of Health and Social Care recommends that adults and children over 4 take a daily supplement containing 10 micrograms of vitamin D throughout the year if they: are not often outdoors – for example, if they're frail or housebound.
Some people may need a higher dose, however, including those with a bone health disorder and those with a condition that interferes with the absorption of vitamin D or calcium, says Dr. Manson. Unless your doctor recommends it, avoid taking more than 4,000 IU per day, which is considered the safe upper limit.
Some side effects of taking too much vitamin D include weakness, dry mouth, nausea, vomiting, and others. Taking vitamin D for long periods of time in doses higher than 4000 IU (100 mcg) daily is possibly unsafe and may cause very high levels of calcium in the blood.

Signs of too much vitamin D
Symptoms of vitamin D toxicity (a.k.a. hypervitaminosis D) can include a loss of appetite, weight loss, excessive urination, and heart arrhythmia. High doses of vitamin D can raise blood levels of calcium (hypercalcemia), which can damage the heart, kidneys, and blood vessels.
The average intact parathyroid hormone levels were 24.2 pg/ml (D3) vs. 30.2 pg/ml (no D3). In summary, long-term supplementation with vitamin D3 in doses ranging from 5000 to 50,000 IUs/day appears to be safe.

Is it a good idea to take a break from daily vitamins and minerals every so many weeks or months for health and vitamin-effectiveness reasons?
