My average patient usually does well supplementing with 5,000 IUs a day of vitamin D3. A child or small woman can often do okay on 2,000-4,000 IUs a day. But it may surprise readers that some people, particularly with autoimmune diseases, may require upwards of 40,000 IUs a day initially to help seal their leaky gut.
Vitamin D. Vitamin D is a fat-soluble vitamin that supports your body's health in a number ways.

Unfortunately, there's a high chance you're not getting enough as 80 percent of Southern Californians are Vitamin D deficient (that says a lot). Dr. Gundry pointed out that it can take 40,000 IU a day of Vitamin D to raise someone's Vitamin D levels, which he says is vital to our health.
Supplementation with 800 to 1000 IU/d of vitamin D or 50,000 IU monthly is safe for most people and can ensure levels of vitamin D within the optimal range.
There's no set time of day that's best to take vitamin D supplements. Some people say taking vitamin D supplements at night is an insomnia risk. There's no research to confirm this, but you might want to take your supplement earlier in the day if you think it's screwing with your sleep.
What happens if I take too much vitamin D? Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body (hypercalcaemia). This can weaken the bones and damage the kidneys and the heart.

The study concluded: Vitamin D supplementation for five years, with or without omega-3 fatty acids, helped reduce autoimmune disease by 22%. Omega-3 fatty acid supplementation, with or without vitamin D, helped reduce autoimmune disease rate by 15%.
The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause nausea and vomiting, weakness, and frequent urination. Vitamin D toxicity might progress to bone pain and kidney problems, such as the formation of calcium stones.
Some patient and doctors refer to the units as milligrams (mg) because it is easier to remember/understand. If you are looking for 2000 mg of Vit D you can feel comfortable purchasing 2000 IU of Vit D. They are the same thing.

Vitamin D Levels
Healthy Bones Australia recommends a vitamin D level of at least 50 nmol/L at the end of winter and during summer higher levels are common in the range of 60-70 nmol/L. Your doctor will only test your vitamin D level (with a blood test) if you are at risk of vitamin D deficiency.
"Adequate levels of magnesium in the body are essential for the absorption and metabolism not only of vitamin D but of calcium as well," Dean states. "Magnesium converts vitamin D into its active form so that it can help calcium absorption.
Can you take vitamin D and magnesium together? Yes. In fact, it's probably best to take both together. Because so many people have low magnesium levels, vitamin D supplements on their own aren't very helpful for a large portion of the population.
Growing evidence has demonstrated that vitamin D has a role in sleep regulation [12]. Specifically, vitamin D deficiency (VDD) can increase risk of sleep disorders and is associated with sleep difficulties, shorter sleep duration, and nocturnal awakenings in children and adults [13,14,15].
