Vitamin D3 is the more effective type to raise levels of vitamin D in the blood. Vitamin D's most prominent effects on the cells relate to bone health. For example, it promotes the absorption of calcium and phosphorus from your gut and these nutrients help to keep muscles, teeth and bones strong and healthy.
The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years.
The Endocrine Society in the USA recommends supplementing with a daily dose of 1000 IU for children who are over a year old and 1500–2000 IU for adults, so as to achieve a concentration of at least [25(OH)D] 75 nmol/L [48].
Vitamin D supplementation may modestly decrease the risk of infection and the severity of COVID-19. Vitamin D deficiency may increase the risk of menopausal symptoms, i.e., hot flashes, sleep disturbances, depression, and sexual function.
At the end of the year-long study, the researchers found that those in the vitamin D group whose blood levels of the nutrient rose the highest – from inadequate at baseline to normal, or replete levels – had a corresponding drop in circulating estrogens and other sex hormones that are a known risk factor for breast ...
When to take vitamin D. It just plain doesn't matter, as long as you take it with food, says Dr. Manson. Her advice: Take it when you'll remember to take it — morning, noon or night — and take it with a meal, she says.

There are quite a few differences between vitamin D and vitamin D3, but the main difference between them is that vitamin D is a fat-soluble vitamin that regulates calcium and phosphorous levels in the body, whereas the vitamin D3 is the natural form of vitamin D produced by the body from sunlight.

The upper recommended limit is 4,000 IUs or 100 mcg per day. Any more than this without professional guidance could put you at risk of overdoing it. So what does science say? This study found that taking a 1-2,000 international unit (IU) dose once or twice a week didn't really change participants' vitamin D levels.
Researchers believe that vitamin D may affect our shut-eye by interacting with the areas of the brain that regulate sleep. We also know that vitamin D plays a key role in supporting the immune system, and managing inflammation may support better sleep quality.
