Dietitian Says Daily Vitamin D Helps Correct Deficiency in Nearly 50% of People

Nearly half the global population is not getting enough vitamin D, and a dietitian said years of daily supplementation helped keep her blood levels in the sufficient range after a low reading.
30 ng/mL is a key threshold cited in the report: levels below that are linked to higher all-cause mortality, while correcting deficiency may support bone health, immune function and respiratory health.
The reported benefits are largely preventive rather than noticeable day to day, with vitamin D described as quietly supporting calcium absorption, lung function and the body’s first-line immune defenses.
High doses are not advised for everyone: people already in the high-normal range may see no added benefit, and excessive intake can cause hypercalcemia, especially in some kidney or rare disorders.
