What to look for in vitamin D supplements
In supplements, two forms of vitamin D are available: D2, called ergocalciferol, and D3, called cholecalciferol. Both are effective, but D3 seems to be more effective at higher dosages.

Manufacturers use yeast to make D2, and they can produce D3 from several sources, including:
lanolin, which comes from sheep’s wool

Who needs to take vitamin D? 
Vitamin D is a fat-soluble vitamin essential for healthy bones, immune function, and cell growth.
Some people are more at risk of developing a vitamin D deficiency. According to the National Institutes for Health (NIH), these groups can include:
National Institutes for Health (NIH)
Infants drinking breast milk: This does not contain much vitamin D. The NIH reports that exclusively and partially breastfed infants receive 10 micrograms (mcg), or 400 international units (IU), of vitamin D per day until weaning.
People who get less exposure to sunlight: People who cannot leave the house, work night shifts, or cover their skin for religious reasons may not get the sun exposure that the body needs to create enough vitamin D. People who live in colder climates may also get less sunlight exposure during the winter months.
Older adults: Older adults who spend more time indoors may be at risk of developing a vitamin D deficiency. According to the NIH, around half of older adults with hip fractures in the United States 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. People with darker skin tones generate vitamin D from the sun more slowly than people with lighter skin. However, it is unclear whether this has any health consequences.
lighter skin
People with obesity: Having a body mass index of 30 or over is associated with lower vitamin D levels, according to the NIH. People who have undergone gastric bypass surgery may also need more vitamin D.
body mass index
People with malabsorption: Conditions such as inflammatory bowel disease affect the gut’s ability to absorb vitamin D. People with such conditions may not eat foods that contain vitamin D due to dietary restrictions.

How much vitamin D do we need? 
A person’s daily requirement for vitamin D depends on age, whether they are pregnant, and whether they have any underlying medical conditions.
The NIH provides these general guidelines:
NIH
Pregnant or breastfeeding people should aim to get 15 mcg (600 IU) 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 a week is usually enough.
However, the American Academy of Dermatology Association recommends getting vitamin D through food sources and supplements rather than sun exposure to limit the risk of developing skin cancer.

Risks and side effects
Taking high amounts of vitamin D by mouth can be toxic. Research suggests that the tolerable upper limit for adults is 100 mcg (4,000 IU) per day.

Some symptoms of vitamin D toxicity include:

It is important to note that vitamin D toxicity usually only stems from excessive supplementation rather than from spending a lot of time in the sun or absorbing too much of the vitamin from food.

Vitamin D supplements can also react with certain medications, such as steroids, weight loss drugs, and medications that lower cholesterol. A person should check with a healthcare professional before taking a new supplement.

Some foods contain this nutrient, including:
foods
oily fish, such as salmon and mackerel

When to contact a doctor 
If a person is concerned that they might not be getting enough vitamin D, a doctor can check for a deficiency via a blood test.
Vitamin D deficiencies can cause conditions that affect the bones, such as osteomalacia and osteoporosis. This is because a deficiency reduces calcium absorption.

Frequently asked questions about vitamin D supplements
According to the NIH the best way to take vitamin D supplements are via food, sun exposure, and dietary supplementation.
NIH

Food: The two main types of vitamin D available in food are D2 and D3. Fatty fish, such as trout and mackerel, and fish liver oil are the best sources of this vitamin. The U.S. and Canada also fortify milk and some milk alternatives with the nutrient.
best sources

Sun exposure: UVB radiation can penetrate the skin and lead to the production of vitamin D3. However, the season, time and length of the day, and the weather can influence this. Also, older people and people with more melanin cannot produce as much vitamin D3 from sun exposure.

Dietary supplements: Supplements contain vitamin D2 or D3. While the way the body processes these in the same way, vitamin D3 may increase the amount of serum 25(OH)D for longer than vitamin D2. Low amounts of this serum can indicate a risk of vitamin D deficiency.

The body converts vitamin D into two forms: D2 and D3.

The NIH states that the body appears to absorb the two types at the same rate. The body then turns the vitamin into serum 25(OH)D.

However, levels of this serum are higher and present in the body for longer with D3 than with D2. This may mean a person has a lower risk of a deficiency if they take D3 supplements.

According to a research review, people should avoid taking more than 4,000 IU per day which is the safe upper limit of daily vitamin D. However, the study also reports that the safety of the dose depends on the person’s current vitamin D status, age, and sex.

Summary
Limited, safe sunlight exposure several times a week can help a person get enough vitamin D, but this may not be possible for many reasons. As a result, some people need to take supplements to get their recommended dose of vitamin D.
A person may only need this supplement during winter, while others may need it year-round.
It is important to note that vitamin D supplements can interact with other medications. As always, check with a healthcare professional before taking a new supplement.
A doctor can take a blood test to look for a vitamin D deficiency. They may then recommend a supplement dosage, considering the person’s age and any other medications.
