Everyone needs vitamin D. You can get vitamin D from the sun and fortified foods, but many people also take vitamin D supplements<\/a>. For most people without a severe deficiency, taking vitamin D in smaller daily doses is better than larger weekly doses.<\/p>\n

There has been debate on the effects of large weekly doses of vitamin D compared to the more traditional smaller daily dose.\n<\/p>\n

For some people, a higher weekly dose of vitamin D could offer more benefits than taking vitamin D every day. A 2023 review found that very high weekly dosages (up to 21,000 IU) reduced intensive care unit (ICU) hospitalization and death in people with COVID-19.\u00a0\n<\/p>\n

A study published in 2018 examined pregnant people who were deficient in vitamin D3. The group that received the higher weekly dose had higher vitamin D blood levels than the group that took a lower daily dose and experienced no adverse effects.\n<\/p>\n

Still, most people who require vitamin D supplements only need a small daily dose<\/strong>. Generally, only people who are severely deficient in vitamin D need a larger, short-term, weekly dose.\n<\/p>\n

Experts recommend that most adults aged 19\u201370 take 15 micrograms (mcg), or 600 international units (IU), of vitamin D per day for healthy bones and immunity. The tolerable upper limit (TUI), or the highest amount that is considered safe, is 4,000 IU for adults.<\/p>\n

Vitamin D Deficiency <\/p>\n

A surprisingly high percentage of people in the U.S. do not get enough vitamin D. About 41% of people in the U.S. have a vitamin D deficiency<\/a>. People aged 20\u201329 are most affected.\n<\/p>\n

Vitamin D deficiency can cause symptoms like:\n<\/p>\n
