Vitamin d3 normal range for female

For adults, a typical level of vitamin D in the blood is 20 nanograms per milliliter (ng/ml) or above. Levels of 12 ng/ml are too low and levels of 50 ng/ml are too high. High or low levels may affect a person’s health. However, needs vary between individuals. The body depends on In this article, we look at: • normal vitamin D levels by age • why vitamin D is important • signs of a deficiency • how to increase vitamin D • if too much is possible Age Amount 0–12 months 10 micrograms (mcg) or 400 international units (IU) 1–70 years 15 mcg or 600 IU 71+ years 20 mcg or 800 IU People who are pregnant or breastfeeding also need 15 mcg or 600 IU of vitamin D per day. Doctors use blood tests to determine if someone has adequate levels of vitamin D. They measure vitamin D using one of two measurements: nanomoles per liter (nmol/l) or nanograms per milliliter (ng/ml). The following table provides According to the Without adequate vitamin D, a person may develop soft, weak, or brittle bones.

Vitamin D deficiency — when the level of vitamin D in your body is too low — can cause your bones to become thin, brittle or misshapen. Vitamin D also appears to play a role in insulin production and immune function — and how this relates to chronic disease prevention and cancer — but this is still being investigated. Although the amount of vitamin D adults get from their diets is often less than what's recommended, exposure to sunlight can make up for the difference. For most adults, vitamin D deficiency is not a concern. However, some groups — particularly people who are obese, who have dark skin and who are older than age 65 — may have lower levels of vitamin D due to their diets, little sun exposure or other factors. The Recommended Dietary Allowance (RDA) for adults is 600 international units (IU) of vitamin D a day. That goes up to 800 IU a day for those older than age 70. To meet this level, choose foods that are rich in vitamin D. For example, choose fatty fish, such as salmon, trout, tuna and halibut, which offer higher amounts of vitamin D, or fortified foods, such as milk and yogurt. Don't overdo it, though. Very high levels of vitamin D have not been shown to provide greater benefits. In fact, too much vitamin D has been linked to other health problems. If you're concerned about whether you're getting enough vitamin D, talk to your doctor about your diet and whether a vitamin supplement might benefit you. • Vitamin D.

Olga Shumitskaya / Getty Images Why You Need Vitamin D Vitamin D, also referred to as calciferol, is a fat-soluble vitamin (meaning one that is broken down by fat and oils in the gut). It is commonly referred to as the "sunshine vitamin" because the D3 type can be naturally produced in the body following exposure to the sun. • Vitamin D2 is naturally found in mushrooms, including shiitake, Portobello, and crimini mushrooms. The vitamin D content increases when these mushrooms are exposed to UV radiation. • Vitamin D3 is naturally found in animals and animal-derived products like milk. It is also directly synthesized in the skin when it is exposed to ultraviolet B (UVB) radiation. Some studies suggest that vitamin D3 raises the vitamin D level in the bloodstream 87% more than vitamin D2. On the downside, vitamin D3 in supplements has historically been synthesized using lanolin derived from sheep's wool. This makes it unsuitable for those who choose to avoid animal-based products.
