Who needs to take natural vitamin D?

This article looks at who may need a natural vitamin D supplement, how much people need by age, and some vitamin D products to consider. It also discusses how to get more vitamin D naturally.

Vitamin D is a fat-soluble vitamin that is essential for healthy bones, immune function, and cell growth.

Who needs to take natural Vitamin D?

Some people are more at risk of developing a vitamin D deficiency. According to the National Institutes for Health (NIH)Trusted Source, these groups include:

  • Infants consuming breast milk: Human milk does not contain much vitamin D. The NIH says that the American Academy of Pediatrics recommends that exclusively and partially breastfed infants receive 400 international units (IU) (10 micrograms [mcg]) of vitamin D per day until weaning.
  • People who get less exposure to sunlight: People who are housebound, who work night shifts, or who cover their skin for religious reasons may not get the sun exposure they need to create vitamin D. People who live in colder climates may also get less sunlight exposure during the winter months.
  • Older adults: Older adults who spend a lot of time indoors may be at risk of developing a vitamin D deficiency. According to the NIH, in the United States, around half of older adults with hip fractures may have inadequate vitamin D levels. Also, the skin’s ability to synthesize vitamin D declines with age.
  • People with dark skin: Dark skin tones contain more melanin, which can reduce the amount of vitamin D the skin makes. However, it is unclear whether or not this has health consequences. Some research Trusted Source suggests that Black people have fewer bone fractures and lower rates of osteoporosis than white people.
  • People with obesity: Having a body mass index (BMI) of 30 or over is associated with lower vitamin D levels, according to the NIH. Individuals who have undergone gastric bypass surgery may also need more vitamin D.
  • People with malabsorption: Conditions such as inflammatory bowel disease affect the gut’s ability to absorb vitamin D. Additionally, people with such conditions may not be able to eat foods that contain vitamin D due to dietary restrictions.

Vitamin  D Deficiencies

If a person is concerned that they might not be getting enough vitamin D, a doctor can provide a blood test to confirm whether or not they have a deficiency.

Vitamin D deficiencies can cause conditions that affect the bones, such as osteomalacia and osteoporosis. This is because vitamin D deficiencies reduce calcium absorption.

Deficiencies in vitamin D can also lead to rickets. However, in the U.S., most companies fortify milk with vitamin D. This has lead to rickets becoming rarer.

How much natural vitamin D do we need?

A person’s daily requirement for vitamin D depends on their age, whether or not they are pregnant, and whether or not they have any underlying medical conditions.

The NIH Trusted Source provides a general guideline as follows:

Age Daily amount of vitamin D required
0–12 months 400 IU
1–18 years 600-2000 IU
19–70 years 600-5000 IU
70 years and over 800-5000 IU

People who are pregnant or nursing should aim to get 600 IU (15 mcg) of vitamin D per day.

Most people meet at least some of their vitamin D requirements by having safe exposure to sunlight. According to the NIH, spending 5–30 minutes in the sun — with the face, arms, legs, or back exposed — at least twice per week is usually enough.

What to look for in natural vitamin D supplements

Vitamin D supplements are available in two forms: D2 (ergocalciferol) and D3 (cholecalciferol). Both are effective, but at high dosages, D3 seems to be more effective Trusted Source.

Manufacturers use yeast to make D2, while vitamin D3 can come from several sources, including:

  • lanolin, which comes from sheep’s wool
  • fish oils, such as cod liver oil
  • algae oil, which is suitable for vegans

Vitamin D supplements are available in different forms, including chewable tablets, liquids, and sprays.

The type of supplement a person uses will depend on their preferences and medical needs. For example, a liquid or spray may be easier to swallow than a pill.
