Who Needs To Take Vitamin D ?

In preserving sturdy skeletal framework, immunity processes and cellular growth, the fat-dissolvable vitamin D performs an indispensable role.

As per research conducted by the National Institutes for Health (NIH), there exist specific cohorts that are at a heightened likelihood of encountering insufficient levels of vitamin D. These populations include:

Newborn Children Consuming Bosom Milk: Human milk doesn’t contain much vitamin D; according to the NIH and American Institute of Pediatrics guidelines, breastfed babies should get 10 micrograms (mcg)(400 international units [IU]) each day until weaning begins.

People With Reduced Access to Sunlight: Individuals living in smaller living quarters may not receive sufficient sun exposure in order to produce vitamin D, and individuals living in colder regions may also see less daylight during cold weather months.

Individuals of advanced age: Those elders who spend an extensive duration secluded within enclosed spaces could potentially encounter heightened susceptibility to vitamin D inadequacy. According to the NIH, up to half of more established Older adults with hip cracks in the US could have inadequate levels of this vitamin; additionally, skin’s capacity to synthesize it decreases over time.

Individuals with a complexion that is rich in melanin: A surplus of said pigment within the skin may impede its production of vitamin D, although it remains ambiguous as to what extent; certain studies insinuate that those possessing darker pigmentation have lower incidences pertaining to bone fractures or development of osteoporosis when compared against Caucasians.

1–18 years15 mcg (600 IU)
19–70 years15 mcg (600 IU)
70 years and over20 mcg (800 IU)

Pregnant or breastfeeding individuals should aim to consume 15 mcg (600 IU) of vitamin D every day.

At least part of their vitamin D needs are met through safe exposure to daylight, according to the NIH. Spending 5-30 minutes outside two times each week, with face, arms, legs, or back exposed is typically enough.
